“…In addition, the drainage from irrigation or treated living water could also be reused as irrigation water for crop growth [36,37]. The drainage water reuse also needs more engineering and mechanical measures, thus increasing the input, and this should pay attention to avoiding secondary pollution and resource wasting [38]. Besides the terrestrial water resources, the sea water resource was another huge storage.…”

Irrigation is the primary agricultural utilization of water resources worldwide, and it produces 36% of the food. The quality of irrigation water influences crop growth and food safety. The coastal river delta region supplies huge area lands for developing agriculture, and the irrigation in this area is composed of many resources for its special location. This study investigated the agricultural water with different resources and evaluated its quality in the Yellow River Delta. The water samples included irrigation water, underground water, and drainage water. The sampling points were designed in the typical areas of Kenli county and Guangrao county in Dongying city, which is the core area of the Yellow River Delta. Through testing the ions composition and the parameters of electrical conductivity (EC), pH, and so on, six evaluation methods were conducted to assess the water quality. The results suggested that the Yellow River water has good quality for irrigation or unconventional water utilization. The high concentration of Na+ and Cl− was the primary problem of the water resource. The rainfall was also another water resource supplement in this region. Therefore, developing saline water irrigation incorporated with salt-tolerant crop cultivation is a rational measure for improving coastal agriculture in the Yellow River Delta.

“…This tool considers three categories of the water quality parameters; crop yield and soil fertility indicators, hygiene and health quality indicators and irrigation systems indicators. A lot of studies assessed the reuse strategy according to regional standards (Beard, Bierkens, & Bartholomeus, 2019;Cakir, 2016;Haldar et al, 2020;Khan et al, 2019;Lavrnić et al, 2017;Müller & Cornel, 2017;Tripathi et al, 2019) or by developing management tools (Al-Mamoori & Al-Maliki, 2016;Ansari, Alavi, & Ghafoori, 2018;Ashu & Lee, 2019;Hatcho, Kurihara, Matsuno, & Horino, 2018;Jiao, Yu, & Xu, 2018;Sharifipour et al, 2020;Tan, Shao, & Gu, 2018).…”

Assessment of agricultural drainage water reuse for irrigation in El-Behira Governorate, Egypt

Agriculture sector and food security of Egypt are under stresses due to the shortage of freshwater budget. Agricultural drainage water reuse can be considered as the most appropriate solution to overcome the irrigation water shortage. Quality of the reused drainage water is of concern, particularly in arid regions, such as Egypt, due to salinity problems. Therefore, water quality assessment for reuse projects is essential. The objective of this work is to assess three different drainage water reuse projects in El-Behira Governorate, Egypt, based on experimental records and water quality index approach. Thirty-six water samples were seasonally collected from three different projects during 2017. Drainage water, freshwater and blended water were evaluated according to the Egyptian and international (FAO) guidelines for drainage and irrigation water. Moreover, CCME-WQI and NSF-WQI were applied to assess the drainage and irrigation water according to the Egyptian standards. Most the recorded parameters for drainage and irrigation water exceeded the permissible limits. The results confirmed the "Poor" and "Marginal" water quality status of all studied drains (drainage water) according to the Egyptian standards. The water quality status of all studied canals (blended water) was classified as "Bad" according to NSF-WQI. These results confirm that current drainage and blended water in the study are shouldn't be used. To avoid deterioration of the soil, crops, food security elements and health protection, treatment systems for drainage water are urgently recommended. Drainage water reuse projects should be carefully installed, and water quality assessment should be accompanied with these projects. This study is the base for an ongoing pilot project of using a low-cost drainage water improvement technology which can be considered as a supplemented tool to drainage water reuse.

“…To address this problem, scattered ponds can be connected to drainage ditches to temporarily store a portion of the water from a drainage area and reduce the peak flow, and this strategy effectively reduces the impact of agricultural drainage on drainage canals and downstream areas [3,4]. Ditch-pond systems can also reduce the nonpoint pollution from farmlands and simultaneously store some of the drainage water for supplemental irrigation during a drought period [5][6][7].…”

Ditch-pond systems can effectively alleviate the adverse effects of agricultural drainage on downstream canals and flood control in downstream areas. In this study, peak flow reduction rate (PFR) and drainage volume detention rate (DVD) are used to evaluate the effectiveness of an off-line ditch-pond system for reducing peak flow, retarding agricultural drainage water, and examining the key influencing factors. The results show that the PFR and DVD of the off-line ditch-pond system are significantly affected by three parameters: weir depth (Ld), weir width (Lw), and pond area-to-drainage area ratio (Ksp). Both the PFR and DVD increase with the increase in Ld, Lw, and Ksp. The effects of Ld and Lw on the PFR and the DVD are significant, whereas that Ksp is relatively small. Adjusting Ld and Lw increases both the PFR and DVD up to 80%. Specifically, Ld contributes 75% of the variations in the PFR and the DVD, and Lw affects only 17% of the PFR variations and 11% of the DVD variations. These findings confirm that an off-line ditch-pond system can be effectively used for the detention of agricultural drainage water. Thus, when such a system is designed with an appropriate diversion weir, the impact of agricultural drainage water on downstream canals and downstream areas can be reduced remarkably.
