Al Msharah River is one of the main controlled feeders of Al Huwayza Marsh in addition to its importance in irrigation of the nearby agricultural areas. A study for evaluating the hydraulic performance of this river has been carried out to develop the ability of the river to accommodate the increase of the required discharge for feeding the marsh and agricultural projects. Achieving this objective require carrying out field hydrological measurements, stage and discharge, at a number of stations distributed along the river for period of six months. A steady one dimensional hydraulic model has been prepared to simulate the flow in this river using the HEC-RAS software (Version 3.1.3). The calibration and verification processes of the model have been carried out by making use of the field measurements. The maximum allowable discharge of this river for the present conditions has been found and the failure, flood, locations have been specified along the river. The required cross sections to develop the capacity of the river have been found considering the marsh and agricultural requirements. ﺍ ﻟﻨﻬﺭ ﺍﻟﻬﻴﺩﺭﻭﻟﻴﻜﻲ ﺍﻷﺩﺍﺀ ﺘﻘﻴﻴﻡ ﻟﻤﺸﺭﺡ ﺍﻟﺨﻼﺼﺔ ﻨﻬﺭ ﺍﻟﻤﺸﺭﺡ ﺃ ﺍﻟﺭﺌﻴﺴﻴﺔ ﺍﻟﻤﻐﺫﻴﺎﺕ ﺤﺩ ﻋﻠﻴﻬﺎ ﺍﻟﻤﺴﻴﻁﺭ ﺍﻟﺤـﻭﻴﺯﺓ ﻟﻬﻭﺭ ﺇ ﺍﻟـﻰ ﻀـﺎﻓﺔ ﻓﻲ ﺃﻫﻤﻴﺘﻪ ﺇ ﺍ ﺭﻭﺍﺀ ﻷ ﻟﻠﻨﻬﺭ ﺍﻟﻤﺠﺎﻭﺭﺓ ﺍﻟﺯﺭﺍﻋﻴﺔ ﺭﺍﻀﻲ. ﺍ ﻟﺘﻘﻴﻴﻡ ﺩﺭﺍﺴﺔ ﺇﺠﺭﺍﺀ ﺘﻡ ﻷ ﺩﺍﺀ ﺍﻟﻨﻬﺭ ﻟﻬﺫﺍ ﺍﻟﻬﻴﺩﺭﻭﻟﻴﻜﻲ ﻟ ﻋﻠﻰ ﺍﻟﻨﻬﺭ ﻗﺎﺒﻠﻴﺔ ﺘﻁﻭﻴﺭ ﺇ ﺍﻟﺘﺼـﺎﺭﻴﻑ ﻓﻲ ﺍﻟﺯﻴﺎﺩﺓ ﺴﺘﻴﻌﺎﺏ ﺍﻟﻬ ﻟﺘﻐﺫﻴﺔ ﺍﻟﻤﻁﻠﻭﺒﺔ ﺍﻟﺯﺭﺍﻋﻴﺔ ﻭﺍﻟﻤﺸﺎﺭﻴﻊ ﻭﺭ. ﺘﻁﻠﺏ ﺇ ﻗﻴﺎﺴﺎﺕ ﺇﺠﺭﺍﺀ ﺍﻟﺒﺤﺙ ﻫﺫﺍ ﻨﺠﺎﺯ ﻓﻲ ﻭﺍﻟﻤﻨﺎﺴﻴﺏ ﺍﻟﺘﺼﺎﺭﻴﻑ ﻗﻴﺎﺱ ﺘﻀﻤﻨﺕ ﻫﻴﺩﺭﻭﻟﻴﻜﻴﺔ ﺍﻟ ﻤﻥ ﻋﺩﺩ ﻋﻠﻰ ﻤﻭﺯﻋﺔ ﻤﻭﺍﻗﻊ ﺴﺘﺔ ﻭﻟﻤﺩﺓ ﺍﻟﻨﻬﺭ ﻁﻭل ﺃ ﺸﻬﺭ. ﺍﺤـﺎﺩﻱ ﺍﻟﺜﺎﺒﺕ ﻟﻠﺠﺭﻴﺎﻥ ﻫﻴﺩﺭﻭﻟﻴﻜﻲ ﻨﻤﻭﺫﺝ ﺇﻋﺩﺍﺩ ﺘﻡ ﺍﻟﺒﻌﺩ ﺍﻟﻨﻬﺭ ﻫﺫﺍ ﻓﻲ ﺍﻟﺠﺭﻴﺎﻥ ﻟﻤﺤﺎﻜﺎﺕ ﺍل ﺒﺭﻨﺎﻤﺞ ﺒﺎﺴﺘﺨﺩﺍﻡ HEC-RAS (Version 3.1.3). ﺒﺎ ﺍﻟﻨﻤﻭﺫﺝ ﻤﻥ ﻭﺍﻟﺘﺤﻘﻕ ﺍﻟﻤﻌﺎﻴﺭﺓ ﻋﻤﻠﻴﺎﺕ ﺇﺠﺭﺍﺀ ﻭﺘﻡ ﻹ ﺍﻟﻘﻴﺎﺴﺎﺕ ﻤﻥ ﺴﺘﻔﺎﺩﺓ ﺍﻟﺤﻘﻠﻴﺔ. ﺍﻟﻨﻬﺭ ﻓﻲ ﺒﻪ ﻤﺴﻤﻭﺡ ﺘﺼﺭﻴﻑ ﺍﻋﻠﻰ ﺘﺤﺩﻴﺩ ﺘﻡ ﻭﺘـﻡ ﺍﻟﺤﺎﻟﻴـﺔ ﺍﻟﻀﺭﻭﻑ ﻓﻲ ﻤﻭﺍﻗﻊ ﺘﺤﺩﻴﺩ ﺍﻟﻔﺸل) ﺍﻟﻔﻴﻀﺎﻥ (ﺍﻟﻨﻬـﺭ ﻁـﻭل ﻋﻠﻰ. ﺍﻟﻁﺎﻗـﺔ ﺘﻁـﻭﻴﺭ ﻭﻟﻐـﺭﺽ ﺍ ﻹ ﺍﻟﻤﻘ ﺇﻴﺠﺎﺩ ﺘﻡ ﻓﻘﺩ ﻟﻠﻨﻬﺭ ﺴﺘﻴﻌﺎﺒﻴﺔ ﺍﻟﻼﺯﻤﺔ ﺍﻟﻌﺭﻀﻴﺔ ﺎﻁﻊ ﺒﻨﻅـﺭ ﺍﺨﺫﻴﻥ ﻹ ﻋﺘﺒـﺎﺭ ﻭﺍﻟﺯﺭﺍﻋﺔ ﺍﻟﻬﻭﺭ ﺇﺤﺘﻴﺎﺠﺎﺕ .
