“…The main objective of this research was to evaluate the effects of future agricultural water management strategies under the influence of climate change on the inflow to the Urmia Lake and the agricultural condition during the years 2015-2040 using the WEAP21 model [22,23]. Considering that the Zarrinehrud and Siminehrud River basins are the largest sub-basins in the Urmia Lake basin, this research was carried out on these two sub-basins.…”

“…All constraints are defined intermittently for each step of time, with regard to the priority of supply and demand. The WEAP model calculates the mass balance equilibrium of water for each node and branch at either daily or monthly time steps [22,23]. Using the time series of the climate, the WEAP model calculates the hydrological cycle components by simulating the rainfall-runoff process at the surface of the catchment area [26].…”

Abstract:In arid and semi-arid areas, unsustainable development of irrigated agriculture has reduced the water level of large lakes such as Aral, Urmia, Hamoon, and Bakhtegan. Urmia Lake, as a hyper saline and very shallow lake, located in the northwest of Iran, has water level reductions of about 40 cm each year over the past two decades. In this research, the indices of environmental and agricultural sustainability are evaluated using performance criteria influenced by climate change and water management strategies for the Zarrinehrud and Siminehrud River basins as the largest sub-basin of Urmia Lake basin. Modeling of hydrologic behavior of these basins is performed using WEAP21 model. The model is analyzed for three future emission scenarios (A2, A1B, and B1), for the period of 2015-2040 and five water management scenarios: (1) keeping the existing situation; (2) crop pattern change; (3) improving the conveyance and distribution efficiency; (4) combining the improvement of conveyance and distribution efficiency with improving the application efficiency using modern technology; and (5) the combination of crop pattern change with the improvement of total irrigation efficiency. The results show that the highest values of indices of environmental sustainability and agricultural sustainability are related to the scenario of combining the crop pattern change with improving the total irrigation efficiency under the B1 emission scenario (B1S4).

“…The Water Evaluation And Planning (WEAP) model of the Stockholm Environment Institute is a water demand, priority and preference driven model which provides a modelling framework for assessing sectoral demand, stream flow, reservoir operation, water conservation measures, allocation priorities and project cost-benefit analyses (Yates et al 2005a;Yates et al 2005b). It is particularly useful for comparing scenarios of hydrological change (Höllermann et al 2010;Harma et al 2012) and has been used for evaluating adaptation options previously (Bonelli et al 2014;Yates et al 2015).…”

The need for credible, salient and legitimate climate change adaptation options in the water sector, which target location specific adaptation requirements, is well recognized. In developing countries, the low-hanging fruit; no-regret options, should be identified with stakeholders and assessed against future changes in water availability and demand, for comparing effectiveness and robustness. Such integrated basin-scale assessments, including reservoir catchment and command areas, can suitably inform adaptation decision-making. In this study, we integrate participatory and modelling approaches for evaluation of reservoir catchment and command area no-regret options addressing water availability and demand in the Kangsabati river basin. Through multi-level stakeholder workshops we identify and prioritize options, followed by evaluation of two reservoir catchment options; check dams and increasing forest cover and three reservoir command options; changing cropping pattern, traditional ponds and waste water reuse, using the Water Evaluation And Planning (WEAP) model. We use four high resolution (~25 km) regional climate model simulations of future climatic factors, along with non-climatic factors affecting water demand, for forcing WEAP. We find that options have varied ability in addressing adaptation requirements. Amongst catchment options, increasing forest cover addresses adaptation requirements more suitably than check dams, while in the command areas we observe mixed abilities of options, leading to the inference that combining complementary options may be a more useful strategy. We conclude by discussing our experiences with this approach in a developing country context, in terms of benefits, limitations, lessons learnt and future research directions.Water Resour Manage (2016) 30:1001-1018 DOI 10.1007/s11269-015-1207-4 Electronic supplementary

“…The data structure and level of detail used can easily be customized to meet the requirements of a particular analysis and to reflect the limits imposed when data is limited [18]. To set up the model, monthly time steps were used in the hydrologic simulation, for the following reasons: (1) compatibility with significant hydrologic process time periods and (2) the existence of the data in a monthly framework.…”

Water resource shortages are always a challenge for Middle Eastern countries in general and for the Palestinian Authority in particular. For over 20 years in Palestine, political factors and a lack of control over water resources have exacerbated the water problem there, seriously affecting water resources, in terms of quality and quantity. This research presents one of the applications of the Water Assessment and Planning (WEAP) model in the Nablus and Tulkarm watershed. The model is applied in evaluating and analyzing the existing balance and the role of treated wastewater and anticipates future scenarios for the management of water resources, taking into account the policies and operating the various factors that may affect the demand and the impact of treated wastewater on the water budget until 2035. The results showed that the amount of treated wastewater in the study area will reach 16 MCM by 2035. The agricultural sector needs 17 MCM and currently only 2.8 MCM are available from artesian wells. The results also showed that one of the reasons for not using treated wastewater is a lack of experience in the planning and selection of wastewater treatment plant sites and of the capacity to match these with agricultural land that could reuse the treated wastewater. Demand management and improvements in living standards are the prerequisites necessary for the proper management of available resources. The results confirmed that the WEAP program provides a solid foundation to assist planners in developing recommendations for the management of water resources in the future, through the detection of hot spots on which to work.
