Abstract: 

The Slunfeh Basin is one of the most important sub-basins of the Coast Basin due to its economic, tourism and environmental importance. This research was conducted in the Slunfeh Basin during the period 2018-2020. The results showed that the hydrographic network was distinguished by its large ramifications, which divided the basin into two streams, each of them from the fourth order to the Al Kabeer Al Shamali River. Annual and monthly precipitation (P) fluctuated from year to year and (P) increased with height at a rate of 0.55 mm/m. The results also showed that the surface runoff (Q) is proportional to (P), so that the (Q) ratio was about 30% of the (P). The real evapotranspiration (ETR) changed from year to year and from month to month and was closely related to (P) and temperature, so that the (ETR) ratio amounted to 43.5% of (P) and there is a decrease in the value of (ETR) coefficient with the Height at 0.05. The average annual storage (R) ratio was 26.5% of (P), as the average value for 24 hydrological years for the total (R) is 363.02 mm. The results of this study contribute to the preparation of dams to store water to form lakes (water harvesting) that contribute to the development of natural resources in general and eco-tourism in particular, which contributes to the economic and social development of the studied basin area.

Keywords: Slanfeh basin, Precipitation (P), Run-off (Q), Evaptranspiration real (ETR), Storage (R), Water Harvesting.
