Abstract:- This study was conducted to monitor surface water salts along the Damietta Branch-Nile River for a yearlong period to evaluate its quality for irrigation. Damietta Branch was divided into twelve stations along through it where water samples were collected and some physicochemical parameters were analyzed. Results obtained confirmed that the SAR value of water along the branch ranged from 3.93 to 60.28 eq/l. According to SAR calculations and characterizations, it is obtained that Damietta branch water is classified as medium (good water quality), which is suitable for coarse textured or organic soil with good permeability and relatively unsuitable in fine textured soils. Nevertheless, its quality varied between several classes (low, medium, high and very high) at different stations separately along the branch. The PAR value of water along the branch ranged from 1.72 to

    1. eq/l. Thus, Damietta branch water is classified as having low to medium risk of soil dispersion (low to medium water quality) but real risk values are for waters low in EC, typically

      < 65mS/m). However, different stations along the branch varied between several classes (low, medium, high and very high). The ESP value of water along the Damietta Branch ranged from 12.96 to 68.68 and with a mean value of 43.04±20.2 along the branch. Chloride, Sodium, Calcium, and potassium concentration values in water along Damietta Branch were distributed in a regular manner as it increased from upstream to downstream along Damietta branch except for one or two stations.: Na+> K+> Cl- >Ca++> Mg++

      1. INTRODUCTION

        Nowadays, scarcity and pollution of fresh surface water is considered one of the most critical environmental issues. Irrigation accounts for approximately 70 percent of global water withdrawal and 87 percent of consumptive water usage. Irrigated farm land accounts for less than a quarter of all cropped land, which only yields about 4045% of global food production. Thus, it is widely anticipated that irrigation will need to be significantly expanded in the future in order to meet future demand, [1]. However, it is unknown if enough water will be sufficient to complete the requisite extension. As it is very likely that water demands in the domestic and industrial sectors are expected to rise in the future and even regions that do not currently face water shortages are thought to be limited in their irrigation and agricultural production, and hence food security will take place, due to a lack of water, [2].

        Thus, registration system and good measurement for water quality, usage and disposal in general and usage of water for irrigation in particular should be monitored and recorded in every region for the prediction of problems which may occur and work on the development of agriculture and the food sector, [3]. This system of monitoring will also help in the assessment of water and food issues on a continental and global scale.

        The composition of salts in water varies according to the source and properties of the constituent chemical compounds. These salts include substances such as gypsum (calcium sulphate, CaSO4.2H2O), table salt (sodium chloride NaCl) and baking soda (sodium bicarbonate NaHCO3). When dissolved in water, salts separate into ions; e.g. sodium chloride breaks down into sodium and chloride ions, [4], [5].

        Chloride is a common ion in irrigation waters. Although it is essential to plants in very low amounts, it can cause toxicity to sensitive crops at high concentrations. In addition, chlorine alone as Cl2 is highly toxic and it is often used as a disinfectant. In combination with a metal such as sodium it becomes essential for life. Small amounts of chlorides are required for normal cell functions in plant and animal life, [6]. Furthermore, Na is an important cation which in excess deteriorates the soil structure and reduces crop yield. When the concentration of Na+ is high in irrigation water, Na+ tends to be absorbed by clay particles displacing Mg2+ and Ca2+ ions. This exchange process of Na+ in water for Ca2+ and Mg2+ in soil reduces the permeability and eventually results in soil with poor internal drainage. This percentage should not exceed 60, (Table 4), [7].

        The sodium adsorption ratio (SAR), the potassium adsorption ratio (PAR) and Exchangeable sodium percentage (ESP) are used to assess irrigation water and provide a useful indicator of its potential damaging effects on soil physical properties, such as soil structure and its permeability, [8]. SAR is used to assess the relative concentrations of sodium, calcium, and magnesium ions in soil and. The permissible value of the SAR is a function of salinity. High SAR leads to a breakdown in the physical structure of the soil. Sodium is adsorbed and becomes attached to soil particles. The highest SAR values were associated with irrigation contaminated and diluted by sea water, [9]. The potassium adsorption ratio (PAR) describes the ratio of K+ to Ca+ and Mg2+. High PAR values in water

        with low EC values can affect soil properties by making the soil more dispersible. While ESP is the percentage of the capacity that sodium takes up, it is known as the exchangeable sodium percentage. The degree of sodium absorption by clay particles is determined by the concentration of sodium in the water as well as the concentrations of calcium and magnesium ions, [10]. This reaction is called cation exchange and it is a reversible process. The capacity of soil to adsorb and exchange cations is limited. Soils with ESP > 15 are seriously affected by adsorbed sodium. The use of water with a high SAR value and low to moderate salinity may be hazardous and reduce the soil infiltration rate. The SAR of irrigation water indicates the approximate ESP of a soil with water, [11], [12].

        This study was conducted in order to assess the irrigation water quality of the Nile River-Damietta Branch depending on the evaluation of its salt concentration at twelve locations over one year using mathematical method (SAR, PAR and ESP).

      2. MATERIAL AND METHOD

        1. Water Sampling

          Water samples were collected seasonally for a yearlong period, from the River Nile-Damietta Branch, Egypt. Twelve sampling stations were selected along the Damietta Branch, from its beginning at Cairo governorate to its estuaries in the Mediterranean Sea, (Fig.1). The global positioning system (GPS) was used for recording these geographical locations, (Table 1). Water samples were collected in HDPE Jerry Cans that were routinely treated with 0.5 N HCl and rinsed before usage with de-ionized

      3. RESULTS AND DISCUSSIONS

    7.6 during winter to 8.3 during summer, while annual mean values of pH varied between 7.1 at Kafr Shokr and 9.1 at Talkha,. During the winter season, water acidity increases in cold weather as a function of increased carbonic acid content that develops in the water when phytoplankton consume less carbon dioxide, [18], [19]. The obtained result was similar to that recorded by Badr [20]. He reported, values of pH ranged from 7.15 to 8.80, with an average value of 7.93 ± 0.33 and were significantly higher in spring and summer relative to autumn and winter. This may be due to the photosynthetic activity of phytoplankton which removes CO2 from the water. Generally, water streams have a pH ranging, between 6 and 9, and any changes in this range in pH can affect life-forms in aquatic systems. If the pH increases above this range, smaller amounts of ammonia are needed to reach a level that is toxic to fish, while when the pH decreases, the acidity of the water increases, affecting the fish, [21]. The obtained results were also in agreement with those found by [19].

  2. Determination of Salinity and EC

    Salinity acts as a key component of life in the aquatic system. It is an important factor which reflects the changes caused by the mixing between fresh water, drainage water and seawater. Schulz and Cañedo [22], defined salinity as composed of multiple major ions that alter the sensitivity of freshwater species.

    The salinity of water of the Nile River along Damietta Branch is shown in Fig. (3). The salinity value of water of the Damietta Branch ranged from 25.7±3.3 at Kafr Shokr station to 41.7±2.8 at Ellesan / Ras Elbr station. This high value is thought to be due to the flow of water from the sea (water intrusion phenomena). Seasonal mean values of salinity varied between 30.6±6.7 during spring and 37.4±5.8 during summer, (Fig.3). The rest stations have

    lower and in between values, with the exception of Talkha, which has a relatively high and cloth value to that of Ellesan/Ras Elbr, (39.52.7). However, this could be attributed also to seawater intrusion, a phenomenon that appeared after the construction of Faraskour dam. So, we can say that the Faraskour dam acts as an artificial barrier which

    prevents natural equilibrium between Damietta Branch an d the Mediterranean Sea, [23] and that appeared clearly in the result. Agriculture can produce highly saline irrigation return flows that enter freshwater. The main drivers of river and stream salinization are the anthropocene, human activities, and land clearing.

    One of the most important thermo physical properties of river water is its electrical conductivity (EC), which maintains almost a linear relationship with total dissolved solids, [24]. EC is related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds. The more ions that are present, the higher the conductivity of water. Electrical conductivity (EC) of water of the Nile River along Damietta Branch is shown in Fig. (3). The electrical conductivity (EC) value of water along Damietta Branch ranged from 16.3±5.7 mS/cm at Meit Ghmr station to 46.9±3.2 mS/cm at Ellesan/Ras Elbr station while seasonal mean values of electrical conductivity (EC) varied between 34.1±14.4 mS/cm during spring and 44.3±13 mS/cm during summer, (Fig.3). This result can be explained through the effect of temperature, climatic change and intrusion of sea water. Abdo, [25] reported in his investigation that salinity was not detected at all fresh water investigated stations along Damietta branch during different seasons, although the mean value of salinity and EC were close to the current stdy. These findings are consistent with those of [25], [26]. Hannigan [27] reported that when water temperature increases, so will conductivity. For every 1°C increase, conductivity values can increase 2-4%. Temperature affects conductivity by increasing ionic mobility as well as the solubility of many salts and minerals. Seasonal variations in conductivity, while affected by average temperatures, are also affected by water flow. In some rivers, as spring often has the highest flow volume, conductivity can be lower at that time than in the winter despite the differences in temperature. In water with little to no inflow, seasonal averages are more dependent on temperature and evaporation.

  3. Determination of Solids in water (TDS, TSS and TS) Total dissolved solids (TDS), total suspended solids (TSS) and total solids (TS) were determined in river water along Damietta branch, Fig. (4). The total dissolved solids value of water along Damietta Branch ranged from 12.4±4 g/l at Meit Ghmr and Kafr Shokr stations to 40.3±2.7 g/l at Ellesan/Ras Elbr station. This high value is thought to be due to the flow of water from the sea (water intrusion phenomena), [28]. In Fig. (4), seasonal mean values of total dissolved solids varied between 25.3±9.4 g/l during spring and 33.2±8.1 g/l during summer.

    The total suspended solids value of water along the Damietta branch, on the other hand, ranged from 4.80.6g/l at Bosat Kareem Eldein/Sherbein station to 53.64 g/l at Ras Elbr/Elgerby station, with a very clothes value of 53.14% at Ellesan/Ras Elbr station.While seasonal mean values of total suspended solids varied between 25.5±16g/l during spring and 29.4±16.7 g/l during summer, (Fig.4)

    In the same way, (Fig.4), seasonal mean values of total solids varied between 52.7±18.1 g/l during spring and 58.9±19.6 g/l during summer and very clothing value in the winter (58.6±20.5 g/l). But the total solid annual value of water along the Damietta branch ranged from 38.4±3.9 g/l at Shrbas/Faraskoor station to 93±6.1g/l at Ellesan/Ras Elbr station.

    In addition to intrusion of sea water which causes the high increase in these parameters values, [29] especially in site 1 and 2 with unusual increase, the low water level in the Damietta branch during the winter period and the increasing rate of water evaporation in summer causes an increase in the concentration of these parameters in seasonal mean value in summer and winter of the current study period, [19]. The Effect of TDS on irrigational water according to Ayers [30] and from the current result shows

    that the TDS of Damietta branch water causes severe problems as its value exceeds 1920 mg/l.

    Fig. (4): Seasonal variations of TDS, TSS and TS (g/l) values in water samples along Damietta Branch – Nile River

  4. Determination of salts toxicity in water

  1. Determination of chloride (Cl)

    Cloride (Cl) concentration value in water along Damietta Branch increased from up to downstream along Damietta branch and especially at stations one and two, it ranged from 0.14±0.001 g/l at Kafr Shokr station to 15.3±0.8 g/l at Ellesan/Ras Elbr station. This value was followed by a relatively high value at Ras Elbr/Elgerby station (14.6±0.5 g/l), (Fig.5). The rest

    stations have lower and in between values, (Table 2). This was mainly attributed to the strong effect of Mediterranean Sea water mixing with Damietta branch water at these stations. The current results are in accordance with that finding by Abdo [25], oppositely El Sayed [31] confirmed the lower value of Cl where the mean value reported was 33mg/l. Seasonal mean values of Cl varied between 5.7±3.6 g/l during spring and 6.4±001g/l during summer.

  2. Sodium and Potassium concentration

    Sodium concentration value in water along Damietta Branch was distributed in a regular manner as it increased

    at Shrbas/Faraskoor station to 8.24% at Kafr Shokr station, with a mean value of 12.6±2.1% along the branch. The rest stations have lower and in between values, (Table 2,3). The results were unexpected because station 1 and 2 were expected to have the highest value due to the strong effect of Mediterranean Sea water mixing with Damietta branch water at these stations. However, the current findings are consistent with that of Mostafa and Peters [34], who found that Na ions (40-110 mg/l) upstream and (21-34 mg/l) downstream had the lowest concentrations among the rest cations. They stated that this distribution was caused by agricultural runoff or natural distengrations. Water in the Damietta branch was classified as permissible water used for irrigation according to Na% which is less than 60% while there were five stations (Damietta Dam Region, Shrbas/Faraskoor, Elsero/Elzarqa, Bosat Kareem Eldein/Sherbein, Talkha) classified as doubtful water for irrigation with Na% more than 60% and less than 80%, (Table 5).

    Table (3): Sodium percent water class, [33]

    from upstream to downstream along Damietta Branch with the exception of Talkha station, which has a higher value than in the following stations, the concentration of Na decreased once more. It ranged from 21.3 mg/l at Kafr Shokr station to 399.9 mg/l at Ellesan/Ras Elbr station, (Table 2). In the same way, potassium concentration value in water along Damietta Branch was distributed in a regular manner from station1 to station 7 as it increased from

    upstream to downstream, then value varied between increase and decrease linear along Damietta branch. This value ranged from 22.39 mg/l at Meit Ghmr station to 287.3 mg/l at Ellesan/Ras Elbr station and this with a mean value of 143.8±117.4 mg/l along the branch, (Table 2). These results were similar to that reported by Sayed [31], [32].

  3. Calcium and Magnesium concentration

    On the other hand, calcium concentration value in water along Damietta Branch is distributed in an irregular manner along Damietta branch. It ranged from 0.87 mg/l at Kafr Shokr station to 5.34 mg/l at Eladlia station and this with a mean value of 2.45±1.58 mg/l along the branch, (Table 2). The magnesium concentration value in water along Damietta Branch distribution was difficult to detect as most stations have very high value and could not be detected easily. The distribution of rest stops (4 stations) is erratic. It ranged from 0.006 mg/l at Eladlia station to 0.6 mg/l at Smnood station and this with a mean value of 0.067±0.173 mg/l along the branch, (Table 2). The observed decreasing in Sodium values landward may be related to the effect of sea water intrusion. However, the increase and decrease in this ions concentration in the Damietta branch is mainly attributed to the discharge of municipal and industrial wastes, domestic wastes discharged, agriculture activity (mineral-rich fertilizers) and application of extensive irrigation in addition to seawater intrusion, [31], [32], [33]

  4. Percent sodium%

    The sodium percent value in water along Damietta Branch is distributed in an irregular pattern. It ranged from 16.16%

  5. Sodium adsorption ratio (SAR)

    SAR value of water along Damietta Branch ranged from

    1.72 eq/l at Smnood station to 25.55 eq/l at Ellesan / Ras Elbr station and this with a mean value of 8.2±7.4 eq/l along the branch, (Table 2). Acording to SAR calculations and characterizations, it is obtained that Damietta branch water is classified as medium (good water quality), (Table

    4) which is suitable for coarse textured or organic soil with good permeability, relatively unsuitable in fine textured soils, [35]. However, different stations along the branch varied between several classes (low, medium, high and very high), (Table 5) and (Fig.6).

  6. Potasium adsorption ratio (PAR)

    PAR value of water along Damietta Branch ranged from

    1.72 eq/l at Smnood station to 25.55 eq/l at Ellesan / Ras Elbr station and this with a mean value of 8.2±7.4 eq/l along the branch, (Table 2). According to PAR calculations and [36], it is obtained that Damietta branch water is classified as having low to medium risk of soil dispersion (low to medium water quality) but real risk values are for waters low in EC, typically <65mS/m). However, different stations along the branch varied between several classes (low, medium, high and very high), (Table 5) and (Fig.6).

  7. Exchangeable sodium percentage (ESP)

ESP value of water along Damietta Branch ranged from

    1. at Ellesan / Ras Elbr station to 68.68 at Kafr Shokr station and this with a mean value of 43.04±20.2 along the branch, (Table 2) and (Fig.6).

      CONCLUSION

      This study applied mathematical indices (SAR, PAR, ESP) that depend on the concentrations of some salts (ions) to evaluate the water quality of the Damietta branches- Nile River. The concentration of Cl and potassium was much higher and exceeded standard levels of the FAO standard for irrigation water. The studied surface water samples show medium and permissible water quality for irrigation purposes for the branch at all, which appeared to be doubtful at some stations along the branch. This study showed a progressive ecological degradation occurred along Damietta Branch at its estuaries. Hence, there should be regular and continuous monitoring for developing ecosystems of the River Nile system and its irrigation system. It is essential to confirm urgent plans for the management of Damietta branch water quality to maintain pollution levels within the permissible values.

      Environmental law should be developed and enforced to prevent the discharge of wastewater such as agricultural, domestic, industrial, or other sources into the Nile River system. Also, the study concluded that the mathematical indices such as SAR, PAR, ESP indices are valid to evaluate the water quality of the study area.
