An application is presented of a new methodology for the real-time operations river-reservoir systems. The based upon an optimization/simulation modeling approach that interfaces optimization with one and/or two-dimensional unsteady flow simulation model (U.S. Army Corps Engineers HEC-RAS). also includes short-term rainfall forecasting, and U.S. HEC-HMS rainfall-runoff modeling. Both forecasted...

With the acceleration of urbanization in a river basin, changes underlying surface structure basin are more and intense, which causes frequent floods. This article aims to analyze applicability HEC-HMS model flood simulation basins influence land use on catchment runoff. Pu River Basin is typical taken as research project. Based changes, soil types, long-term hydrological data Basin, constructe...

The availability, accessibility and quality of data are significant obstacles to hydrological modelling. Estimating the initial values model´’ ’s parameters is a laborious determining task requiring much attention. Geographic information systems (GIS) spatial remote sensing prometting tools for processing collecting data. In this work, we use an innovative approach estimate HEC-HMS model from s...

Los modelos hidrológicos son herramientas esenciales para la planificación y gestión de los recursos hídricos del medio ambiente. En las últimas décadas se han desarrollado diversos hidrológicos, cada uno con características parámetros específicos, el objetivo representar mejor microfísica ciclo hidrológico, aunque, algunos investigadores encontrado que incluso uso técnicas complejas modelamien...

Abstract Frequency of flash floods and droughts in the Mediterranean climate zone is expected to rise coming years due change its climate. The assessment impact at a basin scale essential for developing mitigation adaptation plans. This study analyses variation hydrologic regime small river (the Kalloni Lesvos Island, Greece) by examination possible future scenarios. response was simulated base...
