Abstract :
Flooding can be considered as the most dangerous natural disasters, which often causes many damages to human life and its wealth. Flooding forecasting and its estimation can play a vital role in urban development and planning. One of the most problems in flood estimation is the lack of data, particularly on runoff amount. To overcome the problem, the flood modeling techniques are suggested. In this paper the instance pick discharge value in Varband River catchment was estimated using SMADA software. Also to determine the homogeneous areas, the Langbein and cluster analysis methods were used. The results of the research showed that parameters such as area and main flow length are the most effective factors in making flood in this study area. The results also showed that between the two mentioned above methods, the cluster analysis method was given better estimation and accuracy than Langbein method.
