Therefore, prediction of precipitation and temperature by climate models as well as simulation and optimization of their runoff with suitable models are very important. In this study, four climate models of the Fifth Coupled Model Inter comparison Project (CMIP5) and RCP8.5 scenario were used to forecast future precipitation and temperature for the next two periods including 2020-2052 and 2053-2085. Mean Observed Temperature-Precipitation (MOTP) method was used to reduce the uncertainty of climate models and the change factor method was used to downscale the climate data. Then, the Lumped-conceptual Identification of unit Hydrographs and Component flows from Rainfall, Evaporation and Stream flow data (IHACRES) model and multi-layer Artificial Neural Network (ANN) model were employed to estimate...

Research paper thumbnail of Comparing the Subjective and the Objective Criteria Weighting in Agricultural Water Resources Management

In this study Integrated Water Resources Management (IWRM) approach is applied to the Aras basin ... more In this study Integrated Water Resources Management (IWRM) approach is applied to the Aras basin in the North West of Iran to integrate different criteria for demand management and decision making. Coupling between the River Basin Management Model (MIKEBASIN) and Visual Basic Macro in Excel with the use of COM/.Net interface as a Decision Support System (DSS) have done to evaluate the performance of 9 indicators of structural alternatives. The Analytical Hierarchical process, Entropy method and the strategy of equal weighting are compared as three different methods of Subjective, Objective and Equal criteria weighting. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used for Multi Criteria Decision Making (MCDM) analysis to determine the best management alternatives. The results show that, the alternative 'Increase water efficiency' and 'Decrease cultivated area' is the most preferred option.
