investments have been increasing day by day in basins. Thus, urban rives create
a serious potential risk in the cities. This paper investigates the impacts of the

and ungauged part of the basin. The fluvial flood events were created by
combining hydrological and hydrodynamic models for various events. Flood events
were designed by using Revitalised Flood Hydrograph (ReFH) rainfall-runoff
models. The impact of land use changes was examined by applying various Extent
of urban and suburban cover (URBEXT) parameter of the Flood Estimation Handbook
(FEH) catchment descriptor. Also, flood extents were simulated by linking Flood
Modeler Suite with </span> <span lang="en-us" xml:lang="en-us" style="font-size:.9em;"> </span> <span lang="en-gb" xml:lang="en-gb" style="font-size:11pt;">TUFLOW </span> <span lang="en-us" xml:lang="en-us" style="font-size:10pt;font-family:’Palatino Linotype’, serif;">, hydrodynamic models. The outcomes of these simulations are probabilistic
inundation maps with maximum water depth values. Thus, the impact of the
different percentages of the impermeable surfaces of the sub-catchments on the
discharge and fluvial flood risk at the downstream can be observed. </span> <span lang="en-us" xml:lang="en-us" style="font-size:.9em;"> </span> <span lang="en-us" xml:lang="en-us" style="font-size:10pt;font-family:’Palatino Linotype’, serif;">These outcomes can be used to enrich the flood resilience approaches by
