EVALUATION OF THE HEC-1 MODEL FOR FLOOD FORECASTING AND SIMULATION IN THE HORMOZGAN PROVINCE, IRAN
Hormozgan province rainfall-runoff flood simulation
2009/10/13
Frequent flood occurrences in the Hormozgan province in the south of Iran cause immense damage to infrastructure, parts of cities and numerous villages, and also claim a number of lives. To study floo...
How crucial is it to account for the antecedent moisture conditions in flood forecasting? Comparison of event-based and continuous approaches on 178 catchments
soil moisture accounting flood forecasting moisture conditions
2009/7/22
This paper compares event-based and continuous hydrological modelling approaches for real-time forecasting of river flows. Both approaches are compared using a lumped hydrologic model (whose structure...
