Enhancing uncertainty of regional climate models for climate change projection at Western Nile Delta
Publikováno v:
Water Science, Vol 38, Iss 1, Pp 225-238 (2024)
ABSTRACTThe objective of this research is to refine the precision of uncertainty estimates associated with Regional Climate Models (RCMs) for precipitation forecasts in the Western Nile Delta region of Egypt up to the year 2100. This refinement is pr

Stepped spillways have many applications in dam structures, and river engineering. Moreover, stilling basins can be constructed with lower costs as energy dissipation by adding appurtenances to these stilling basins. This study aims to investigate th

Water scarcity in Egypt is an escalating challenge due to the ever-increasing water demands and limited resources. Economically, agricultural drainage water reuse (ADWR) in irrigation is an essential option to cope with freshwater shortage. However,
