REMOTE SENSING-BASED DYNAMIC ESTIMATION METHOD FOR OUTFLOW PROCESS OF UNGAUGED FREE OVERFLOW RESERVOIR
A remote sensing-based dynamic estimation method for the outflow process of an ungauged free overflow reservoir comprising the following steps: estimating the storage volumes of the water reservoir at different water levels from the water level-area relation curve of the water reservoir by using a digital elevation model, and thereby establishing an area-storage volume relation curve of the water reservoir; obtaining the storage volumes of the water reservoir at the corresponding times; obtaining the change of the storage volume of the water reservoir through accumulative calculation on the change of the storage volume in the time periods corresponding to the two remote sensing images; gradually approximating an outflow coefficient of the water reservoir by using a bisection method; taking the final approximation result as the outflow coefficient of the ungauged reservoir, and calculating the outflow process of the water reservoir during floods.
