Overview of LDK-WEAP Model in AZ-Basin (GW Over-Abstraction)
A WEAP Model was developed to measure the groundwater over-abstraction inAmman-Zarqa Basin, This model was simulated for 15 years (2001-2015). The modelalso shows the water budgeting and mass-balance in the basin using Simplified Rainfall-Runoff Hydrological Modeling

WEAP Simulation of Water Cycle vs. Reality
General WEAP Schematic
Water Modeling Mechanism in WEAP
Full accounting of water flows throughout watershed:
❑ Rainfall-runoff modeling❑ Climate-driven evapotranspiration❑Groundwater-surface water interaction❑Programmable operating rules for infrastructure❑ Represent water demands from all sectors
WEAP Rainfall-Runoff Model
- A Catchment Simulation Method- is Based on the following Criteria:
PrecipAvailableForETLC = PrecipHU * AreaLC * 10 -5 * PrecipEffectiveLC
ETpotentialLC = ETreferenceHU * KcLC * AreaLC * 10 -5
PrecipShortfallLC,I = Max ( 0, ETpotentialLC,I - PrecipAvailableForETLC,I )SupplyRequirementLC,I = (1 / IrrFracLC,I ) * PrecipShortfallLC,I
SupplyRequirementHU = S LC,I SupplyRequirementLC,I
WEAP Rainfall-Runoff Model
"crop coefficient": An estimate of consumptive water use by crops based on evapotranspiration values."Effective Precip. ": Effective Precipitation (EP) is the amount of precipitation that is actually added and stored in the soil. During drier periods less than 5mm of daily rainfall would not be considered effective, as this amount of precipitation would likely evaporate from the surface before soaking into the ground. Effective precipitation enters the soil and becomes available to the plant.
Functionality of WEAP
The main menu in WEAP provides access to the most important functions of the program. There are seven sub-menus:
1. Area Menu2. Edit Menu3. View Menu4. General Menu5. Schematic View6. Advanced Menu7. Help Menu
View Bar Contains:1. The Schematic View2. The Data View 3. The Results View4. The Scenario Explorer View5. The Notes View

Water Demand for Zarqa Governorate
First task ‘’ calculate water demandAssume that :
• A demand site
• population is 2.025 million in 2018
• Population growth rate is 2.5 %
• Annual water use (per capita demand) is 280/cubic meter person/ year
• Consumption is 75%
