Abstract
Study area Samsun/Atakum
province is almost under threat of flooding in each year. In this region, the
main reason of devastating flood is the influence of the Degirmen stream
especially during March, April, and July and due to seasonal rainfall, which
eventually makes the district vulnerable to flooding. In addition, the
human-based constructions and the collapse of water retaining structures are
among the main causes of flooding. In this study flood risks of Samsun Degirmen
stream determinate by MIKE 11 and GIS.
Numerical model selection for studies provides advantages in developing
and changing the solutions with time. The flood modeling studies include the
following steps: digitization of topographical data and preparation of digital
elevation model using ArcGIS, simulation of flood discharges of different
return periods using a hydraulic model (MIKE 11), and preparation of flood risk
maps by integrating the results of first two steps. Hydrological models were
also created corresponding to 100 and 500-year return period floods. A 1D
hydrodynamic model was created with MIKE powered by DHI software; MIKE 11. The flood
inundation maps demonstrated that some areas, from the upstream to downstream
of the Degirmen stream basin, is affected by 100 and 500-year return period
events
