6. 1. Work progress with Model applications The overall objectives of the Jordan case study (Zarqa River Basin) are to implement, test, develop, evaluate, and to exploit an innovation approach to water resources management, in close cooperation with local and regional stakeholders which is intended to increase efficiencies through applying the following modeling procedures: A. Water Resources Model (WRM). B. Rainfall-Runoff Model (RRM) C. Land Use Change Model Univeristy of Jordan, Amman, Jordan

7. 1.1. Contribution to Requirements and Constraints Analysis, WP 01 • Stakeholders with an interest in sustainable water management have been identified. • The issue database, obtained on the base of the stakeholders answers to the issue questionnaire, including, physical conditions, water management, water demand, and water supply. • Analysis of the water issues. • Data requirements were compiled and identified.

9. A. Water Resources Model (WRM) • The Water Resources Model is a daily water budget. Interacting objects River Basin Object Scenarios Interacting objects of the Zarqa River basin were identified based on Digital Elevation Models (DEMs) which is completely prepared in GIS lab at the University of Jordan. Univeristy of Jordan, Amman, Jordan

10. B. Rainfall-Runoff Model (RRM) The RRM rainfall-runoff model is a dynamic basin scale water budget model that operates at a daily time step. It is designed for estimating sub-catchments outflow as a function of basin characteristics including, primarily, elevation distribution, land cover and land use, and rainfall and temperature as dynamic inputs. Basin Characteristics were identified using the preparedDigital Elevation Model. Univeristy of Jordan, Amman, Jordan

11. Watershed delineation with Digital Elevation Model, DEM. • Fifteen Digital Topographic maps of 1:50,000 were used to get full coverage of the study area. • Contour lines were digitized from the Digital Topographic maps using ArcView GIS. Univeristy of Jordan, Amman, Jordan

12. Watershed delineation with Digital Elevation Model, DEM. • TIN was created, and DEM with resolution of 30 m was derived using ArcView GIS. • The software Watershed Modeling System (WMS) can directly use DEM for watershed characterization and delineation. Univeristy of Jordan, Amman, Jordan

23. Flow direction and accumulation was determined with Topographic Parameterization Program (TOPAZ). • Watershed outlet of Zerqa River was defined on downstream between its confluent with Jordan River. • Interior outlets were defined for creating watershed sub-basins. • Drainage basins were defined from defined streams. Zerqa Basin of 4120 km2 in area was subdivided into 6-major sub-basins considering Topographic, rainfall variation, and urban distribution. Univeristy of Jordan, Amman, Jordan

36. Next Steps • Rainfall data is available. But, Due to Basin Rainfall Variability , it is under identification to compute average daily Basin Rainfall. • Nine - rain gages out of 33 have selected to build Thiessen network. These are Jerash (AL0004), Zarqa (AL0015), Suweileh (AL0017), Amman Hussein Collage (AL0022), Rumeimin (AL0028), Qasr el Hallabat (AL0049), Um el Jimal (AL0059), Wadi Es- Sir (AL 0057), and Um el Quttein (F0001). The selected rain gages cover the entire watershed . Univeristy of Jordan, Amman, Jordan

40. Next Steps • Daily Runoff and Temperature data were identified and ready to be used in models . • Number of wells, quantity and usage of ground water that are distributed all over the entire watershed were identified. They are under specification for each sub-catchment. • Data of king Talal Dam, Khirbet As-Samra Treatment Plant were identified and ready to be used in model. Univeristy of Jordan, Amman, Jordan
