الملخص الإنجليزي

Water is one of the most significant issues in the modern world, the challenges of managing water resources start from a single catchment area like Alana valley which is 231 km 2 GIS maps are prepared with all required layers and valley boundary, then the boundary and other GIS layers are checked by a Global Positioning System (GPS) instrument in the field.

The locations of demand and supply are fixed by the GPS instrument, then samples of water are collected from each source to check concentration of DO and BOD from laboratory tests and flow of each source were measured.

All collected data with field data are processed to be used properly in WEAP, for example; all shape-files from GIS maps and field GPS points, required to be processed and change to WGS84 type and extension "ship" by MAPINFO program, and other programs like CropWat4 used for obtaining and check reference Evapotranspiration, and after basic scenario (Reference scenario) generation, six more scenarios were added for each quality, groundwater, proposed reservoir, climatic change, advanced irrigations and downstream requirement.

.

The present research has managed the water resources of Alana valley by using Water Evaluation and Planning (WEAP) software which was developed rapidly during recent drought years by Stockholm Environment Institute.

The WEAP can model demand and supply and build different scenarios that may occur, and it is supported by Geographic Information System (GIS) layers, all climatic data, hydrologic data and any other data available from previous studies and models to give a clear view about Integrated Water Resources Management (IWRM).

The major results were as follows : The application of WEAP program for Alana valley shows that annual runoff in normal year was about (69.8 MCM), for Non-agricultural demands (all water demands except irrigation) represent only 7.3 % of all demands which it was for 1st year of simulation and it was less than (1MCM), and total demand was (8.8 MCM), about 75 % of non-agricultural demands represented by Khalifan village.

Even though the irrigation demands are high, but only 10 % of all arable area are irrigated which is (486ha) and the rest depend on rain or are not cultivated.

Most of irrigation water demand can be reduced too much by increasing the irrigation efficiency.

Water projects from lining canals to building a reservoir system will benefit this area and it's downstream.

At the head of the Alana river (springs), the quality (taste, odor, color, DO and BOD) are good, but it will lose this quality passing through the Alana valley due to disposal of wastes and sewage, but it still in safe side.

Proposed Gali-Bla Dam with capacity of less than 1 MCM, will serve the area in recreation and non-agricultural demands, but it will not cover the need of one month for agriculture demand and nor increases the Gali-AliBeg fall flows.

This area requires reservoir or system of reservoirs with capacity (5MCM) at least to satisfy all demands during summer, which now depend mostly on groundwater resources.

Other options and recommendations are given in this study, like increasing flow of downstream is possible by adding a small dam upstream of the Gali-AliBeg fall for controlling flow of the fall.
