limitation of water resources in iran motivates sustaining and preserving of the resources in order to supply future water needs. fulfilling these objectives will not be possible unless having accurate water balance of watersheds. the purpose of this study is to estimate the water balance parameters using a distributed method. the large number of distributed models and methods was studied and “...

Simulation of flow hydrograph at an ungauged site recently has attracted considerable attention. A distributed rainfall-runoff model not only can describe the spatial heterogeneity of physiographical and hydrological characteristics in the catchment, but also can simulate the hydrological processes inside the studied area. If a distributed rainfall-runoff model can be adequately verified based ...

Abstract. Karst trough and valley landforms are prone to flooding, primarily because of the unique hydrogeological features karst landforms, which conducive spread rapid runoff. Hydrological models that represent complicated hydrological processes in regions effective for predicting but their application has been hampered by complex model structures associated parameter set, especially distribu...

Water resources management is critical due to its importance for human lives. In this context, we have developed a web-based system for hydrological applications that integrates geospatial processing services and mapping mashups to provide an interactive and user-friendly geoportal interface to the configuration and execution of scientific models. The server side provides hydrological model log...

This paper considers distributed hydrological models in hydrology as an expression of a pragmatic realism. Some of the problems of distributed modelling are discussed including the problem of nonlinearity, the problem of scale, the problem of equifinality, the problem o f uniqueness and the problem of uncertainty. A structure for the application of distributed modelling is suggested based on an...

For reservoir basins, complex underlying surface conditions, short flood confluence times, and concentrated water volumes make inflow forecasting difficult cause forecast accuracies to be low. Conventional models can no longer meet the required accuracy values for control operations. To give full play role of reservoirs in maximize use resources, high-precision is urgently needed as a support m...
