MIKE FLOOD model-based study on operation scheme of Pajiang River Flood Storage and Detention Area
摘要
Abstract
In order to ensure the reasonable operation of Pajiang River Flood Storage and Detention Area and guarantee the safety of the flood control of the mid-lower reach of Beijiang River,the relevant operation scheme is studied herein.Based on the MIKE FLOOD platform,the 1-D and 2-D coupling hydrodynamic mathematical models of Pajiang Flood Storage and Detention Area are established,and then the comparative study is made among five drafted operation schemes,from which the flood peak discharge at Shijiao Hydrological Station and the submerged area of itself under different schemes are analyzed,the result from the comparison shows that the effect from appropriate delay of the operation start-time of the flood storage and detention area on reducing both the flood peak discharge at Shijiao Hydrological Station and the flooded loss within the area is more obvious.On the basis of this,it is determined that the scheme of that "fully starting the operation of the whole flood storage and detention area in one time,when the water level at the estuary embankment of the river reaching to 22.2 m" is most optimal.Under this scheme,if the floods of P =0.3％,P =0.5％ and P =1％ occur,the flood discharges at Shijiao Hydrological Station can be reduced by 1 150 m3/s,1 407 m3/s and 1 017 m3/s with the maximum submerged area of 86.1 km2.The relevant study result can not only provide a reference for the decision-making of the management of Pajiang River Flood Storage and Detention Area,but also can provide a reference for the study of the operation scheme of the other flood storage and detention area.关键词
