“…When vertical and/or horizontal flow occurs, water loss results in the fishponds becoming unsustainable. Other potential sources of water loss include evapotranspiration which is also significantly high during a typical dry season with average temperatures of 33° Celsius in Southern Nigeria [ [29] , [30] , [31] ]. In critical cases of lowered groundwater table and water loss, the ponds dry up and result in the fish's death, which constitutes a significant financial loss for the farmers.…”

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.

Irrigation return flow (RF) is a critical component of the water cycle in an agricultural watershed, influencing the flow regime of downstream river. As such, it should be accurately quantified when developing water resources management plans and practices. Although many studies have proposed ways to quantify RF, uncertainty in RF estimates has not been determined to improve reliability and credibility. This study examines how conceptual (CON) and physically-based (PHY) parameterization approaches affect RF uncertainty. Results showed that PHY had a smaller amount of RF uncertainty compared to CON, as parameters of the PHY approach could be regulated based on their physical meanings. This study also found that the application of constraints created based on the relationship between the conceptual parameter and physical characteristics of irrigated plots could effectively reduce RF uncertainty made using the CON approach. This study demonstrates the benefits of the physically-based parameterization approach and the application of constraints on conceptual parameters to RF estimation.Water 2020, 12, 1125 2 of 14 rainy days. A modeling approach has been recommended to effectively differentiate runoff by rainfall and RF by irrigation in runoff drained from a plot [3,16,17].RF can be estimated by simulating the overall water balance, which consists of rainfall, irrigation, surface drainage, evapotranspiration, and infiltration. Surface drainage is a key variable for quantifying RF, and two parameterization schemes are commonly used to describe surface water drainage processes: conceptual and physically-based approaches. The conceptual approach (CON) employs parameters that are conceptually defined (rather than physically) using the linear reservoir theory [11,[18][19][20][21]. On the other hand, a physically-based parameterization approach (PHY) represents the drainage processes using the broad-crested weir equation [3,7,[22][23][24][25].Parameterization schemes have their own strengths and weaknesses in terms of complexity, accuracy, and uncertainty. Even when there are no drainage observations for calibration, for instance, the parameter values of PHY may be accurately estimated from their physical meanings. In contrast, it can be difficult to reasonably determine the values of conceptual parameters without calibration due to the scale-dependency of system heterogeneity and nonlinearity [26]. In the case of an ungauged watershed, the applicability of conceptual parameters has not received sufficient systematic analysis to guide the selection of approaches.This study evaluated the applicability of conceptual and physically-based parameterization approaches for estimating RF of ungauged watersheds. The accuracy and uncertainty of RF estimates made using the two approaches were compared to each other. We also discuss how expert knowledge can help refine the value range of a conceptual parameter, aiding the reduction of uncertainty in the conceptual approach [27,28]. This study demonstrates how hydrological reasoning ca...
