“…Since then, the model has been applied to several basins, including the application to the California's Sacramento River Basin to evaluate the impact of future climate scenarios on agricultural water management in the region, and to investigate whether water management adaptation could reduce potential impacts of climate change [30]. WEAP has been used for statewide modeling in California in support of assessment of statewide future water demand and supply scenarios, as part of the California Water Plan [31].…”

Aims: Provide a review of key features and several applications of the family of Integrated Water Resources (IWR) models, as the key analytical tools used in evaluation of hydrologic conditions in support of the integrated regional water management (IRWM) programs in California. Methodology: IWR models are a family of models consisting of the Integrated Groundwater and Surface water Model (IGSM), the Integrated Water Flow Model (IWFM), and the IWFM Demand Calculator (IDC). IGSM is an integrated model that simulates the complete hydrologic cycle for a basin. The California Department of Water Resources (CADWR) has upgraded and enhanced the IGSM code and developed an enhanced version, called IWFM. In addition, CADWR extracted the land surface processes module of IWFM as an independent unit, called IDC, which can be used as a stand-alone model for estimating agricultural water demand, groundwater pumping, and deep percolation. The IWR models have been applied to many basins throughout California to evaluate hydrologic conditions, including evaluation of land and water use, surface water and groundwater flow, stream-aquifer interaction, reservoir operation, land subsidence, and regional water quality conditions. An ArcGIS-based Graphical User Interface provides a robust modeling platform for the IWR models. Results: The IWR models have had significant success in analysis of various types of water resources projects, such as integrated regional water management programs,

“…Adgolign et al, (2016) applied the WEAP model to modeling the surface water resources allocation of the Didessa Sub-basin, and the Abbay Basin. Furthermore, the WEAP model was applied for assessment of future and current water demands (McCartney et al, 2009;Mounir et al, 2011;Rayej, 2012), to evaluate water resources development based on an equilibrium scenario of the current water demand (Mutiga et al, 2010), to analyze the impact of planned water resource development on current and future water demands (Chinnasamy et al, 2015), to assess water demand and supply under changing climatic scenarios (Malla et al, 2014), and to manage water shortages (Tesfatsion et al, 2011). This paper aims to present a framework for modeling long-term water allocation and analysis of alternative strategic scenarios in the Bilate Catchments.…”

A water shortage stress might have resulted from the extensive water resources development plan in the Bilate catchment owing to the rapidly growing population, irrigation development expansion, climatic variability, and socioeconomic development. Furthermore, the lack of sufficient knowledge about available water resources and lack of coordination in water resources management skills in the basin often aggravates the competition of fixed waterresources among the users. Therefore, modeling long-term water allocation should be implemented to determine the optimal allocation of water resources, maximize the overall benefits without compromising ecological requirements, and propose mitigation measures that may alleviate the problem of water scarcity during peak demand periods. The Water Evaluation and Planning (WEAP) model is generally used in the formulation and evaluation of alternative plansfor responding to water-related problems and water resources developments. To assist in the assessment of spatialtemporal streamflow simulations within watersheds, the Soil and Water Assessment Tool (SWAT) employed in the Bilate River and its sub-catchments. The Indicators of Hydrologic Alteration (IHA) and CROPWAT 8.0 software programs were used to estimate streamflow requirement (IFR) and the crop water requirement, respectively. Three development scenarios include the agricultural and socio-economic development effect, climatic change, and alternatives that were built in the long-term planning horizons (2013-2050). The modeling water allocation for each sub-catchment was done by considering the Ethiopian water allocation and apportionment criteria and water act priority order. The result revealed that agriculture growth (increasing irrigation projects) and socio-economic development caused a significant increase in water demand. Hence unmet water demands in different parts of the catchments were increased. Similarly, the effect of climatic variation scenarios has been increased unmet demands in the middle year of the planning horizon(2030-2050). Therefore, developing adaptation strategies scenarios helps to mitigate water scarcity and improve water availability for productive use.

“…WEAP has been used mainly to assess both the current and future water management, and projecting the impacts of climate changes [MCCARTNEY et al 2009;RAYEJ 2012], it uses an approach based on scenarios which facilitate the exploration of a large range of variants in order to satisfy demand in a balanced way. Flexibility of the tool and its adaptation to the requirements of different data and environment allows the modelling of a basin like Seybouse, where the data are rare and the conflicts between the various water users are very current [AOUN-SEBAITI et al 2013].…”

“…It is a model of simulation at physical base which integrates water demands from all sectors directly with water supply elements like rivers, tanks, groundwater, channels, desalination and hydropower projects [RAYEJ 2012]. This software is based on the representation of the water system in network form whose nodes (catchment basins, demand sites, different supply sources) are linked through transmission and return flow links [BOUKLIA-HASSANE et al 2016].…”

Water in the Seybouse River basin is getting scarce, yet it is the key to its economic development. A fast growing population, expanding agricultural and industrial sectors and the impacts of climate variability, create demands for new water sources and innovative management of water resources and services. The object of this study is the water resources management in the lower Seybouse basin characterized by a steady increase of water demand to meet different uses. This study takes into account changes in water demand of different urban, agricultural and industrial supply process. Our approach is to integrate data in WEAP modelling software to simulate current and future water balance and then to analyse the situation of water in different scenarios, socio-economic development and climate change to 2050. This software is based on the representation of the feeding system in a form of the network of water demand and supply. Our findings reveal the vulnerability of the region in its ability to the pressures resulting from the increase of needs of different sectors at the horizon of the forecasted period. They also indicate the need for larger mobilization of new resources into the system and lay the foundations for a sustainable water policy in the northern region of the Seybouse valley.
