The improved scheme can ensure the south branch to be open to navigation and the flow here not to be broken in low water seasons , and it will have active effect on protecting the south branch and fuyuan town . this study is an attempt of applying three - dimensional mathematical model in analogue calculation and analysis of flow , sediment and riverbed movements in a long river reach . it is very important for the future thorough research , and has great significance for promoting the application of the three - dimensional model to resolve 本研究是三維數學模型對較長河段水流、泥沙、河床運動模擬計算分析的一次嘗試,其對今后進一步深入研究和應用三維模型解決工程實際問題,完善模擬方法、提高模擬水平,真正發揮數學模型其省時、省力、靈活方便和模擬細膩等在研究水沙運動規律和河床變形等方面研究中優勢具有重要的意義。

( 3 ) dynamic state of groundwater in riverside displays : at middle and supreme areas of yeerqiang , no matter abundant water season or low water season , river water always recharge groundwater . at downsteam , in abundant water season , river water recharge groundwater ; in low water season groundwater recharge the river ( 3 )近河岸地帶地下水動態分析顯示葉爾羌河中上游地區,無論豐水季節還是枯水季節,河水均補給地下水:下游地區,豐水季節,河水補給地下水;枯水季節,地下水補給河水。

At the end of 2003 , yunda successfully completed the marketing and energy - saving promotion planning for the chengdu power bureau during the low water season , designed and produced a lot of promotional materials and souvenirs , and created wide - spread social benefits 于2003年年底,成功完成了成都電業局枯水期市場營銷及節電宣傳策劃,并為其設計制作了大量的宣傳品及紀念品,取得了廣泛的社會效益。

In using the fuzzy optimization , the paper separately computes the subordinative degree of the storage capacity that is opposite to the main high - water season in every stages , and then , determines the present storage capacity 在模糊算法中分別計算各個時段相對于主汛期防洪庫容的該時段的庫容隸屬度,然后確定該時段的庫容。
