The paper illustrates a Decision Support System (DSS) for multi-reservoir water resource systems, named WARGI (Water Resources system optimization aided by Graphical Interface). WARGI was upgraded in the SEDEMED II Project to implement a mixed approach that uses optimization and simulation techniques to select the best combination of proactive and reactive measures under drought conditions. The...

To answer the impacts under specific what-if scenarios together with simulation tools has been demanding in different environmental problems. In this contribution, a general software framework for time series scenario composition is proposed to deal with this issue. It is done through providing an interface to process available raw time series data and to compose scenarios of interest. These co...

This study examines the change in current 100year hydrological drought frequencies in the Mediterranean in comparison to the 2070s as simulated by the global model WaterGAP. The analysis considers socio-economic and climate changes as indicated by the IPCC scenarios A2 and B2 and the global general circulation model ECHAM4. Under these conditions today’s 100-year drought is estimated to occur 1...

It is increasingly recognized that the land-use change, especially urbanization has influenced hydrological attributes intensely. But in most urban designs, flood prediction is considered through type of land use (residential, industrial, and so on) and density. However, experiences show that this method has not been very successful. As a result, the present study aims to investigate and explor...

This paper evaluated an integrated water resources management approach through linked WEAP-MODFLOW model. Study area is Ravasnar-Sanjabi plain located in Kermanshah province in the west of Iran. A MODFLOW model was evaluated and then, accepted as a groundwater model for the region in present research. Schematic WEAP model was provided as representing general features of water resources system a...

A hydrological model based in the cellular automata paradigm, capable to handle extended geographical domains discretized in a large number of cells is presented. The automata simulates the natural surface water flow by tracking local water stocks, book-keeping precipitation, infiltration, evapotranspiration, and intercellular flows. The flow resistance is represented with a relaxation local pa...

The Coupled Model Intercomparison Project Phase 6 (CMIP6) provides more scenarios and reliable climate change results for improving the accuracy of future hydrological parameter analysis. This study uses five CMIP6 global models (GCMs) to drive variable infiltration capacity (VIC) model, then simulates response upper middle Huaihe River Basin (UMHRB) under shared socioeconomic pathway (SSPs). s...
