【摘要】：基于大量的實(shí)測和調(diào)研資料,建立了能反映陽澄淀泖區(qū)現(xiàn)狀河網(wǎng)、圩區(qū)分布及水工建筑物調(diào)度的水動力模型,經(jīng)率定和驗(yàn)證后能夠用于該區(qū)域的洪水模擬�；赪eb技術(shù)、GIS技術(shù)和數(shù)據(jù)庫技術(shù),研發(fā)了嵌套水動力模型的動態(tài)洪水風(fēng)險(xiǎn)圖管理系統(tǒng)。針對任意降雨、邊界條件、水工建筑物參數(shù)及調(diào)度參數(shù),系統(tǒng)能快速調(diào)用模型進(jìn)行模擬計(jì)算并生成動態(tài)洪水風(fēng)險(xiǎn)圖。與在線預(yù)報(bào)數(shù)據(jù)結(jié)合,可實(shí)現(xiàn)洪水預(yù)報(bào)預(yù)警,為洪水風(fēng)險(xiǎn)圖在防洪減災(zāi)、洪水管理、洪水預(yù)報(bào)等方面提供技術(shù)支撐和應(yīng)用借鑒。
[Abstract]:Based on a large number of measured and investigated data, a hydrodynamic model which can reflect the current river network, the distribution of polder area and the regulation of hydraulic structures in Yangchengdian area is established. After calibration and verification, the model can be used to simulate the flood in this area. Based on Web technology, GIS technology and database technology, a dynamic flood risk map management system based on nested hydrodynamic model is developed. For arbitrary rainfall, boundary conditions, hydraulic structure parameters and operation parameters, the system can quickly call the model to simulate and calculate and generate dynamic flood risk map. Combined with on-line forecast data, flood forecast and early warning can be realized, which can provide technical support and application reference for flood risk map in flood control and disaster reduction, flood management, flood forecast and so on.
