Since 1999 the Yuvacik Dam reservoir has been one of the most important arteries supplying water to the city of Kocaeli, located in the southeastern part of the Marmara region of Turkey. Although considered to be a large dam, the spillway is operated every year, especially during the spring months, as large quantities of water come from the basin due to high rainfall and snowmelt. In this respect, the operation of the reservoir becomes an important task as critical decisions have to be made at the right time, with limitations due to the discharging canal. For this purpose, atmospheric-hydrological model integration and application studies were developed to provide an improved decision support system for the operation and management of Yuvacik Dam reservoir. In the present study, HEC-HMS version 3.0.1, released by US Army Corps of Engineers, Hydrologic Engineering Center in April 2006, is applied to the Yuvacik dam basin with a snow component in a semi-distributed manner.
