Distributed-Framework Basin Modeling System: I. Overview and Model Coupling

To better simulate the river basin hydrological cycle and to solve practical engineering application issues, this paper describes distributed-framework modeling system (DFBMS), which concatenate a professional model system, geographical integrated database management system. DFBMS has two cores, are distributed-frame (DF-PMS) double-object sharing structure (DOSS). An area/region that same mechanism of runoff generation and/or movement is defined as one type feature unit (HFU). DF-PMS adopts different kinds HFUs whole watershed cycle. The concept most important component DF-PMS, enabling process with empirical equations or physical-based submodules. Based on underlying source code, uniform data structure, named DOSS, proposed accomplish integration information (GIS), new way exploring temporal GIS. numerical schemes including conceptual distributed models. feasibility practicability proven through its in study areas.
