A review on WEAP21 model for managing water resources

Abstract

Water resources allocation for the optimisation of water uses at each user end is one of the major challenges to the policymakers and stakeholders. Water resources planning needs multi -disciplinary approach for sustainable development. The present paper provides an extensive review on Water Evaluation and Planning Model version 21 (WEAP21) applications as a decision-making tool for water allocation problems and water resources planning in different aspects including water quality analysis, groundwater modelling and climate change simulations. From this literature-summarised review, WEAP21 can be concluded as a powerful IWRM tool for priority-preference based simulations under various scenario generations.
