中國沿海地區(qū)城市洪水預測與風險分析

前言

　　This dissertation is an outcome spanning the joint of thecenturies from 1999 to 2002. It is an attempt to studythe new features of flood disasters during the speededup period of urbanization in the coastal areas of China，and to find out the intrinsic relationship that flood riskvaries with the socio-economic development， and theideas and modes of flood risk management that maymeet the demands of flood prevention. The new meansof numerical simulation techniques for floodriskprediction and analysis in urbanized areas are alsodiscussed with case studies of three coastal cities，Shenzhen， Guangzhou and Tianjin.In the past century， development and utilization of thelarge scale structural engineering measures andinformation techniques have greatly enhanced the floodcontrol capacities of human being， which satisfied thefundamental requirements of development in floodplainsduring the process of population explosion， increasedpressure in food supplies， and rapid urbanization.

章節(jié)摘錄

　　Numerical model for the simulation of flooding in urban areas willbe an effective method. It will be used to predict the floodbehaviors under the varied conditions of urbanization as well as theflood control systems， offering a scientific basis to realize the urbanflood issues for the future and to make flood risk managementsystems reasonably. In recent years， the author has undertaken floodrisk research projects for some coastal cities， such as Shenzhen，Guangzhou， Shanghai and Tianjin. An Urban flood simulationsystem has been developed and perfected during this process. Themodel combined with the advantages of both Finite Volume Methodand Finite Difference Method has been transformed from regulargrid to non-structural irregular grid. In order to use the model in theurban regions， a simulation method for drainage systems has beenimproved. A set of pre-and post-treatment software serving for themodel has been developed. With the function of imaging displayand operator-computer communication， the results of flooding arevisible on screen， which makes the model to be capable to inquirethe information during the calculation and to deal with the suddenaccidents such as levee break. It has now played an important rolein the fields of flood prediction and forecast， flood risk analysis，flood damage assessment， flood control planning and flood fightingdecision support systems.
