The present study was initiated with the objective of simulating and predicting the effect of future development on the groundwater flow and levels. This supports applications for future planning and wise management of water resources. The study area extends south of El Nubariya canal including Sadat City area and its vicinities in the western Nile delta region. A numerical groundwater flow model (MODFLOW) has been employed to simulate flow and get the budget of groundwater in the study area. The model showed that about 28,101,041 m 3 /day of surface water is infiltrated to groundwater dominantly from canals and excess irrigation water. About the same quantity (28,101,052 m 3 /day), is discharged from groundwater through production wells, open drains and through some reaches of canals. Three development scenarios were simulated to give predictions of the impact of future increasing recharge, construction of new canal and new open drains, and also increased pumping on the groundwater levels in the study area.
Inland waterways are an environmentally friendly and efficient mode of transport. At locations along the Nile River, Egypt, navigation is hindered requiring expensive, resource‐intensive corrective. An increasing number of navigational bottlenecks have occurred between 1982 and 2015 because of changing river channel morphologies. This study provides a suitable method for evaluating navigation conditions within a reach of the Nile River. A 2D morphological model combined with a geographic information system application was created to assess the navigability of a reach of the Nile River, and different maintenance strategies were evaluated. Different scenarios of varying water levels, dredging operations, flow discharge fluctuations, and river channel morphological changes were considered. Results reveal that dredging operations, alone, cannot be adopted as a permanent solution for navigation bottlenecks, with the riverbed returning to its original state within 10 years. An important output of the method is the generation of reach scale hydro‐morphodynamic maps that show the main morphological features, navigation bottlenecks, and navigation conditions. These maps aid in the development of strategic navigability plans and in evaluating long‐term improvement measures. The method presented is applicability to large river systems worldwide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
