Suitability of Surface Water from Mouillah Wadi of Algeria for Irrigation Purposes
Developments in Soil Salinity Assessment and Reclamation, 2012
Salinity is one of the most severe environmental factors limiting the productivity of agricultural crops. In this chapter, evaluation of water quality of Mouillah wadi was carried out in order to assess its suitability for irrigation purposes. Mouillah wadi is a subbasin of Tafna watershed which is situated in the north-west of Algeria. It feeds the Hammam Boughrara dam with a capacity of 177 Mm 3 . This wadi has important sources of pollution contaminating water whose quality deterioration is a direct consequence of the discharge of the ef fl uents of all categories in surface water (industrial and urban wastes). To evaluate the water quality, chemical parameters such as the residual sodium carbonate (RSC), the magnesium hazard (MH) and the permeability index (PI) using US Salinity Laboratory Staff salinity classi fi cation and the Wilcox diagram were determined, and seasonal variation diagrams were prepared. The electrical conductivity values show the dam waters to be of marginal quality. The waters of Mouillah wadi are of poor to harmful quality according to Wilcox classi fi cation. The calculated values of SAR and % Na plotted on SAR and Wilcox diagrams versus conductivity indicate a good to doubtful use of the dam water for irrigation. High salinity, % Na, Mg hazard and RSC values at Mouillah wadi limit the use for agricultural purposes.

E3S Web of Conferences
This study investigates the suitability of Garmat Ali river (Iraq) for irrigation uses. Two stations were chosen: station A; far from any polluted water discharge point, and station C; near to a very contaminated water discharge point). Water samples were picked up and tested for pH, electrical conductivity, total dissolved solids, sodium, potassium, calcium, magnesium, bicarbonate, sulfate, chlorine, and nitrate. Three samples were collected in January and March 2019 from each site, to reflect the wet season in Iraq. Besides the classification of water quality parameters of Garmat Ali river for watering, other parameters were also calculated, such as sodium adsorption ratio, soluble sodium percentage, exchangeable sodium percentage, magnesium hazard, kelly ratio, permeability index, and potential salinity. According to the Food and Agriculture Organization (FAO) guidelines, the overall results showed that the salinity and chlorine were within the range that causing severe problem t...

This study was conducted to assess the irrigation water quality parameters of the water resources in irrigated lands of Konya-Sarayönü Gözlü Agricultural Enterprise. Water samples were taken from deep wells of the research site and soil samples were taken (0-30, 30-60 and 60-90 cm depths) from different sections of the research site. Water quality parameters and soil physicochemical characteristics were investigated.Soil texture of the research site was identified as clay and clay-loam. Soil pH values varied between 7.11-7.90, EC values varied between 696-803 µmhos/cm. Irrigation water pH values varied between 6.08-7.45 and EC values varied between 1071-1989 µmhos/cm. Water samples were classified as C 3 S 1 (highly saline) according to US Salinity Lab classification system. Despite high salinity levels of irrigation waters, a salinity problem was not encountered in soils of the research site. However, that does not necessarily mean that there won't be a salinity problem in the future since irrigation practices of the region are quite new and sufficient time has not elapsed yet for salt accumulation in soils.Relevant cultural measures should be taken to prevent possible future salinity problems and farmers should be trained about water quality and salinity problems.

The surface water and groundwater hydrochemistry at 45 locations in Qus City, where farming activities are considerably intensive, was investigated to evaluate their irrigation suitability. The irrigation suitability of the collected water samples was evaluated based on the water salinity (EC), effective salinity (ES), sodium percentage (%Na), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), soluble sodium percentage (SSP) and magnesium adsorption ratio (MAR). The results showed that most of the water samples classified under the first class (ES < 3 epm) of water are suitable for irrigation. Based on the SAR classification, it was found that almost all the water samples in the study area are classified under the S1 water class; it is excellent and suitable for irrigation with no harmful effects from sodium. Furthermore, the US salinity laboratory (USSL) classification revealed that most of the water samples fall within the C2-S1 (medium salinity with low sodium hazard) and C3-C1 (high salinity with low sodium hazard) classes. The Wilcox diagram and %Na also classify the water samples as excellent, doubtful, or unsuitable, individually. SSP showed that the majority of the water in the study area range from permissible to doubtful. The overall results showed that the water in the study area is suitable for irrigation, with the exception of few locations that require careful application in irrigation methods.
Assessment of groundwater suitability for irrigation in Madinah City, Saudi Arabia
Arabian Journal of Geosciences, 2015
Over the years, erratic rainfall pattern coupled with increasing population has led to the reliance on groundwater as an alternative and sustainable source for crop irrigation to meet increasing food demand. Irrigation of crops though essential, if not done with care through good practices and use of quality water can lead to soil salinization and ecological unsustainability. This study was carried out to assess the salinity of groundwater used for irrigation in three sub catchments in the Upper Athi River Basin of Kenya. Stratified random sampling technique was used to select representative boreholes and shallow wells for the study. In all, water from 17 boreholes and 17 shallow wells spread across the study area were sampled and analysed for selected physico-chemical properties. Standard methods were used for all the laboratory analysis; temperature, pH and electrical conductivity (EC) of water samples were measured in the field. The results obtained were compared with FAO Water Quality Guidelines for Irrigation. pH ranged from 4.2 to 7.13 indicating weak acidity with about 75% samples falling below lower guideline value. EC values ranged from 467 to 1328 μS/cm which were within FAO and NEMA permissible limits for irrigation purposes. All salts ions were within permissible irrigation water suitability standards except CO 3-, Cl and K +. 97% samples had above the recommended carbonate concentrations while 80% had more potassium than the recommended value with the remaining 20% being boreholes. In relation to chloride concentrations, samples from shallow wells are not suitable for sprinkler irrigation since they were above the recommended levels; however, 58% were suitable for surface irrigation. For the boreholes, chloride concentrations were suitable for both surface and sprinkler irrigation. In conclusion, the boreholes had less ions as compared to shallow wells. This research may serve as a preliminary study to provide baseline information that may direct future water quality assessment studies in the study area.
Assessment of Reservoir Water Quality Using Water Quality Indices: A Case Study from Jordan
International Journal of Engineering Research and Technology, 2020
This study was conducted to evaluate the water quality of King Talal Dam (KTD) in Jordan and its suitability for irrigation purposes based on the measurements of several physicochemical parameters and water quality indices. Surface water was sampled from seven different locations in the dam. The values of electrical conductivity (EC) and total dissolved solids (TDS) indicate that KTD surface water is relatively saline but still falls within the permissible category for irrigation. The dam's water is suitable for irrigation based on the sodium adsorption ratio-(SAR) and magnesium hazard-(MH) data. It lies between permissible to doubtful categories with respect to the results of sodium percentage (Na%) and lies within the marginal category for irrigation based on Kelly's ratio-(KR) values. Therefore, crops that are not sensitive to sodium and soils with light textures and good permeability are recommended. The data of irrigation water quality index (IWQI) showed that KTD water distributed between moderate to high restrictions for irrigation uses, which indicates that the dam's water can be used to irrigate plants with moderate to high salt tolerance and in soils with moderate to high permeability and good leaching of salts. KTD water requires special measures to reduce salinity and sodium hazards.
Physical and chemical properties for water in Wadi Almawaheb and Qa' Asawad were studied for the purpose of classification of this water for irrigation use, where it was adopted on cations ions (Calcium (Ca 2+), Magnesium (Mg 2+), sodium (Na +), Potassium (K +), anions ions (bicarbonate (HCO3-), Chloride (Cl-), Sulfate (SO4 2-), pH value, Electrical Conductivity (EC),and Sodium Adsorption Ratio (SAR), the results showed that, 50% water samples fall within the water class (C3-S1) and 50% water samples fall within the water class (C2-S1) according to USSL system. Whereas, in FAO system, the samples fell within the class (increase in salinity hazard) for the salinity hazard, In addition, pH values were within natural limits.

This study aimed to check the groundwater quality for irrigation in Al-Swawa, Sirte District (Libya), from the dug wells and open ground tanks supplied by the Great Man-Made River. Water samples were collected, and the following parameters were analyzed: pH, electrical conductivity (EC), sodium (Na +), potassium (K +), calcium (Ca 2+), magnesium (Mg 2+), chloride (Cl-), and bicarbonate (HCO3-). Sodium adsorption ratio (SAR), soluble sodium percentage (SSP), ratio of sodium carbonate (RSC), magnesium adsorption ratio (MAR), Kelly's ratio (KR), permeability index (PI), and total hardness (TH) were calculated. The results showed wide variations in water quality parameters for both sources of water. Mean values for pH of 7.7 and 8.4, EC of 8.0 and 0.7 dS m-1, and SAR of 12.0 and 4.8 mg L-1 were recorded at wells water and Great Man-Made River water, respectively. Well, waters were classified as a very high salinity, while the Great River was classified as a medium hazard. Well, waters gave values of Clvaries from 13.0 to 51.5 mg L-1, while Great Man-Made River gave values less than 10 mg L-1, which classified as moderately Clhazard. Except for a sample of the wells, all analyzed water samples showed values of SSP more than 60%, which exceeds Eaton's measure value. It is concluded that wells water just suitable to irrigate a very salts tolerant crop, while the Great Man-Made River water is suitable for irrigation with moderate leaching if intensive management is adopted and followed.
The present study concerns the evaluation of the quality of the water used in irrigation in the perimeter of the DAR EL GUEDDARI wastewater treatment plant, these waters are often purified water coming from the WWTP and sometimes water pumped into the canal. rejection from the Sebou wadi. For this, we realized a set of measures such as: the temperature, the pH, the electrical conductivity, the biochemical demand in oxygen BOD5, the chemical demand in oxygen COD, the suspended matter MES, the total nitrogen (N ( tot), ammonium NH4 +, nitrates NO3-, total phosphorus P (tot), ortho-phosphate PO43-, sulphates SO42-, sodium Na +, chlorides Cl-, potassium K +, metals such as: Cr, Cd, Pb, Hg, Cu, Mn, Fe and Zn The results obtained during this study indicate that the physicochemical quality of the WWTP water used for crop irrigation does not always meet the irrigation water criteria in agriculture (Moroccan standard for irrigation water). They are characterized by low levels of dissolved oxygen, high levels of TSS, BOD5, COD and sodium and low levels of heavy metals such as Cd, Pb, Hg, Cu, Mn. The combination of the electrical conductivity CE and the SAR sodium absorption coefficient according to the irrigation water classification diagram of RISVERD allows to classify these waters in the box of poor quality water. However, the water pumped into the sewage disposal canal from Oued Sebou is likely to meet the criteria set by the Moroccan standard for irrigation. On average, they are less rich in nutrients (NPK) with moderately lower values than wastewater from the WWTP and they are characterized by low levels of sodium, conductivity, SAR and pose no risk of salinization or alkalization; with the exception of nitrates, which have an average value of 4.2 mg / l.
