In this article we study flood control system of middle and lower X river. Regarding to the complex water system, extensive range, remarkable regional difference, great changeable spatial scale, complicated and verious regional composition, and also stong coupling effect, mutul influnce and restriction, etc, we proposed the overall assumption ahout building mathmatical model of flow and sandiment transport and calculate model for its related links. This achievement is on the base of previous mathmatical model of flow and sandiment transport and starting from exploration of law of flow and sandiment transport, and is the fruit of deeply research on calculate model of various intra-regional hydraulic units in the framework of numerical simulation including calculate model of stream and bedload in distributary estuary and junction, movable boundary of network, sediment tranport rate of lake, resistance of movable and morph of riverway’s cross-section.

Middle and lower reaches X river the rivers and lakes accumulate and release result real-time appraisal value simulation this article to prevent floods the system take X river middle and lower reaches as an object, has outlined the author in recent years in the large-scale complex flood prevention system water sand movement value simulation foundation, faces middle and lower reaches X river to prevent floods successfully the plan proof demand water sand mathematical model to transform for faces X river flood prevention system flood prevention project evaluation demand middle and lower reaches X river the real-time flood forecasting dispatch mathematical model.In order to adapt the real-time forecast dispatcher fast, the accurate appraisal request, proposed based on the hydrodynamics circulation trundle computation pattern, the real-time adjustment pattern and the real-time flood prevention dispatch experimental mechanism.Has realized the hydrology real-time adjustment method and the hydrodynamics mathematical model coupling, has established based on the hydrodynamics real-time adjustment pattern.Under prevents floods the system flood composition in view of X river in to be complex, enters the high water time not to be inconsistent, has Y river three to block the flow the question, for the unification rivers and lakes various key stations flood forecasting and the dispatch result appraised, middle and lower reaches X river in real-time flood forecasting scheduling model, inserts Y river three to move the boundary the computation pattern.Guards against floods the period through X river middle and lower reaches to try the movement, solved the flood-control measure to accumulate and release the result appraisal and the project optimization regulation pattern well and so on the essential difficult problem, has provided the quota basis for the flood prevention plan plan formulation and the real-time flood dispatch plan optimization, the main achievement has applied middle and lower reaches X river prevents floods plans and guards against floods dispatches in the plan.
