【摘要】:隨著浦東新區(qū)社會和經(jīng)濟(jì)的迅速發(fā)展、水利建設(shè)和防汛設(shè)施不斷完善,全區(qū)江河水情及工情都發(fā)生了變化,現(xiàn)行內(nèi)河防洪警戒水位標(biāo)準(zhǔn)已不能滿足需要,因此需重新檢驗(yàn)和制訂相適應(yīng)的警戒水位。為對城市防洪中暴雨引起的河道水位雍高進(jìn)行預(yù)警,結(jié)合浦東河道水系,將全區(qū)劃分成3個(gè)區(qū)域;將現(xiàn)有水位遙測站與區(qū)域空間分布相結(jié)合,選取各區(qū)域代表水位站;對各代表水位站的特征水位值做經(jīng)驗(yàn)頻率計(jì)算,得到常遇洪水位;根據(jù)各代表站的常遇洪水位,結(jié)合所在區(qū)域的水面積、河道防洪能力及社會經(jīng)濟(jì)條件等,綜合核定得到各區(qū)域的警戒水位。新的警戒水位可滿足需求,在汛期中有效地減少警戒水位超限次數(shù)。
[Abstract]:With the rapid development of society and economy in Pudong New area, water conservancy construction and flood control facilities have been continuously improved, and the water conditions and working conditions of rivers and rivers in the whole area have changed, and the current standard of alert water level for flood control in inland rivers can no longer meet the needs. Therefore, it is necessary to re-check and establish the appropriate alert water level. In order to early-warning the river water level uvula caused by heavy rain in urban flood control, the whole area is divided into three regions according to the Pudong river system, combining the existing water level telemetry stations with the regional spatial distribution, the representative water level stations in each area are selected. The empirical frequency of the characteristic water level of each representative level station is calculated, and the frequent flood level is obtained. According to the frequent flood water level of each representative station, combined with the area of water, flood control capacity and socio-economic conditions of each region, the warning water level of each area can be obtained by comprehensive verification. The new alert water level can meet the demand and effectively reduce the number of warning water level overruns during the flood season.
