The hydrological regime of the Tigris River in the city of Baghdad

Abstract

Water drainage pattern in the rivers and changed the nature of the renewed feeding areas in the basin in terms of topographic and geological conditions and climate in addition to the human role in organizing the process flow within these basins. This study addressed the development of the Tigris River Hydrological in the city of Baghdad and found that the annual rate of water drainage in the Tigris River was driven down very significantly, especially in the past twenty years, and since 1996 up to 2014 record flow rates of less than the overall rate of discharge of water, a (950 m3 / s ), in addition to the quarterly decrease the discharge rates, especially since the beginning of the year 2000 and took converge all four seasons rates within the (500 m3 / s). As is the drainage class (501-600 m3 / s) higher categories the disposal again for the discharge of daily Vtakerrt in ten years (2001-2010) Add to it has become water attributed to the River recorded rates within the (27 m) after it was recorded rates of between (28 - 30 m) in the nineties, and resulted in the discharge and the alleged lack of water and low water flow capacity of any reduction in the current speed of the water of the Tigris River in the city of Baghdad to the low speed rates over the previous years.
