Integrated Water Resources Management in Jabla Basin: Applied Hydrological Research

Abstract

This research aims to achieve integrated management of the water resources which are available temporally and spatially in Jabla basin.

The research problem is the water mismanagement and loss. The basin is divided into (12) hydrological basins according to the dividing lines of water.

The water resources in the basin are evaluated according to the average precipitation, the average evaporation rate, and the average of the inbound water from the monthly and annual rain. This is done with various potentials according to the hydrological years at the level of basins, and according to the size of the surface flow rate in a cumulative method. The size of the underground flow rate was assessed for each basin separately.

The priority of water sectors (drinking water, agriculture, and industry) was defined according to Water Demand Management.  

The future and current water balances for the hydrological year (2034-2035) were assessed with various probabilities and they were positive. The water surplus reached (17.6mm³). (2.6mm³) of it is surplus that is wasted in the sea, and (15mm³) of it is groundwater surplus.                            

A future water strategy was set, according to the water balance which has water surplus, to achieve best investment of the surplus in order to develop the basin economically and socially. This is to be done by establishing successive dams in the water course for storing water and drilling wells.
