Componentization Of Flood Routing And Peak Staggering Dispatching Model And Case Study

From basin floods to river floods,the evolution of floods,the encounter of flood peaks in main and tributaries,and the dispatching of staggered peaks in reservoirs have always been the traditional research topics,which have been attached great importance to,but they are not fully controlled.Policymakers are concerned about the occurrence and development of river floods,especially the role of River-related reservoirs.There are many research results on river flood events,but affected by dynamic changes and uncertainties,River flood disasters are still frequent and widespread,which have a serious impact on people's production and life.The randomness and development process of flood events have great uncertainties.In the process of response,it is extremely necessary to have a reliable and manageable means for flood routing and peak staggering dispatch.To meet this important requirement,this paper adopts component technology to granularize the model method of flood routing and peak staggering dispatch into controllable units,encapsulates each unit into components according to component standards,and establishes component library of model method;based on component library,two control modes of"human-computer interaction"flood peak staggering dispatch and adaptive peak staggering dispatch are proposed;and the Shaanxi section of Wei River Basin is taken as an example.Based on the integrated platform,a simulation system of river flood routing and peak staggering dispatching is built by using knowledge maps and components,which provides a feasible application attempt for decision-making of peak staggering dispatching of river flood.The main contents and research results are as follows:(1)River flood routing and Componentization of its model method.The classical Muskingan model method for river flood routing is introduced and grouped into units.Component technology is used to encapsulate the Muskingan model method,which realizes the modularization of river flood routing model method.(2)Componentization of flood peak staggering dispatching model and its dispatching mode.There are many models and methods for reservoir dispatching,but they are not flexible in practical application and divorced from reality.Component technology can also be used to componentize the dispatching models and methods.For single reservoir and multi reservoir flood control dispatching,the optimal dispatching model is established,and the component library of flood peak staggering dispatching model method is established.In order to improve the flexibility and operability of the dispatching process,two peak staggering dispatching modes of flood peak staggering dispatching and adaptive peak staggering dispatching under"human-computer interaction" are proposed.(3)Based on the integrated platform,the simulation system of river flood routing and peak staggering dispatching is developed and implemented.On the basis of knowledge visualization technology and component development technology,taking Shaanxi section of Wei River Basin as an object and based on integrated platform,a simulation system for river flood routing and peak staggering dispatching is built,which realizes"human-computer interaction" and visual flood dispatching decision-making with strong adaptability.(4)Taking the "11.9" flood event of Wei River as an example,the simulation was carried out.Compared with the actual occurrence and development process of "11.9" flood in Wei River,the evolution process of "11.9" flood is simulated by using the developed simulation system of river flood routing and peak staggering dispatching.The comparison and verification of two dispatching modes,adaptive peak staggering dispatching and"man-machine interaction"peak staggering dispatching,are carried out under artificial control.In the process of flood routing,early warning,emergency response and emergency pre-warning are carried out.With the limited storage capacity of reservoirs,the effect of peak staggering is improved,especially the visualization process,so that the occurrence and development of floods can be controlled,which tests the feasibility and effectiveness of the system.
