Abstract
The current study was conducted to both water quantities and quality along Rosetta Branch. The main water stream is divided into segments to facilitate the studying of different features. There are three main regions which are: areas affecting Rosetta Branch, Neutral region, and areas affected by Rosetta Branch. Spatial and temporal water monitoring and assessment were executed. The water share studies indicate that, the five drains could reach up to the half of the water content of mainstream especially during Low-peak periods in addition, El-Rahawy drain is the largest contributor to the domestic drainage. The Water Quality Index (WQI) was used to simplify the water quality results where the results reveals a dramatic deterioration (mostly ranked as ‘Poor’ or ‘fair’) in water quality after the confluence of El-Rahawy drain with main stream then the self purification has a role in slightly improving of water quality. Synchronize with that, evaluation for Dinking Water Treatmnt Plants (DWTPs) located in the selected study area was done showed high sensitivity of DWTPs to changes in source water quantity and quality. In a parallel way, the potential risks could raise in produced drinking water were assessed which pointed out that, there are a couple of high risks could be raised as a consequences of water quality change and the deficiency of some DWTPs components. Water Poverty Index (WPI) was selected as a multidimensional tool to express the water status in the selected study area. The resulted WPI value is (0.44) which is located in the middle of the WPI’s scale. Then, this study has highlighted a group of the adaptation measures (short, mid, and long-term) in order to alleviate the water stress and improve the water recourses in the study area.
