Using Soil and Water Assessment (SWAT) Model to Evaluate the Satellite and Gauges Based Precipitation Data, and Understand The Hydrologic Impacts of Human Activities in the Tigris and Euphrates River Basins.
Abstract
The Euphrates and Tigris rivers are the first and second-largest rivers respectively in Western Asia. The river basins are shared by four countries: Iraq, Iran Syria, and Turkey. In this study, the streamflow in the Tigris and Euphrates river basins is simulated using the Soil Water Assessment Tool (ArcSWAT-2012) model integrated with remote sensing and geographical information systems. The simulation has been applied in two periods: the first period extends from 1931 to 1970 and the second period begins 1971 and ends in 2010. The division into these two periods will help to evaluate the impact of anthropogenic activities such as the construction of dams on the upstream of the Tigris and Euphrates rivers. Most of the dam constructions began in the late 1970s. In this work, we will examine four widely used satellite and gauged-based precipitation products for hydrological evaluation in the Tigris and Euphrates river basins, with an area of ~700000 km2 by SWAT. The multiple precipitation data sources will be evaluated viz. - Global Precipitation Climatology Centre (GPCC), Global Historical Climatology Network Daily Temperatures (GHCN-D), Climate Prediction Center (CPC), and Asian Precipitation Highly Resolved Observational Data Integration towards the Evaluation of water resources project (APHRODITE).
