Abstract

The flood is second destructive incident in Iran. Greater understanding of different points of view Hydro meteo logy and watershed systems and analysis modeling of rainfall, runoff, determination of flood zone reference the hydrological and hydraulic conditions in the watershed, not only in terms of financial and legal, but also to predict and help flood warning systems are helpful ways. The purpose of this research provide the perfect solution to establish flood warning system using hydrological models and hydraulic models in the basin upstream is of the Germichai dam. In hydrological studies after restructuring the data, flood frequency analysis has been done up to a day at the station. To choose distribution for all stations using the Best-fit test based on L- moments of stations, three parameters were normally distributed. Applying the ratio of the maximum one-day flood into flood peak moment values for different return period flood peak moment of the river at the dam site Germichai was calculated. River flooding, especially in the current conditions of relatively high recurrence caused flooding along the river due to the steep terrain of the river is low. By examining the persistence of storms and their levels, early warning alarms were calculated for each of the stations. After the set time alarm events based on the frequency of Miane station, Flood warning system for flood areas within the flood level is designed to suit the threshold.
