flood discharge level 中文意思是什麼
flood discharge level
解釋
洪水位-
Jahezi reservoir is located at the northwest arid area of china, the primary tasks of which are flood control land irrigation. it has been reinforced in 2003 so the discharge capacity and the safety of dam were increasing at large degree, which created the conditions to utilize the flood sufficiently by raising the limited water level
夾河子水庫地處我國西北乾旱區，主要承擔防洪及灌溉任務， 2003年除險加固完成後，水庫的泄流能力及大壩安全都有很大程度的提高，為水庫抬高汛限水位，實現洪水資源化創造了條件。 -
We can learn from the result that adopted the different limited water levers in flood season could raise the benefit of reservoir but not increasing the risk of reservoir at the same time. the risk rate of flood control will increase if the limited water level is raised, but the increased flood control risk will not very large at frequent flood owing to the discharge capacity of reservoir is larger
分析發現，水庫實現分期汛限水位控制，可以在不增加水庫防洪風險的同時提高水庫的興利效益，抬高水庫的汛限水位，防洪風險率會增加，但由於水庫的下泄能力較大，在常遇洪水情況下其防洪風險率增加幅度並不會很大。 -
Abstract : based on the results of hydraulic model test and remote - control ship model, the unsteady flow characteristics in the downstream approach channel and the reaches from three gorges project to gezhouba project and navigation conditions in these reaches during the tgp flood - discharge are analyzed. the measures of raising navigation discharge level and improving navigation conditions are given
文摘:根據水工模型試驗成果，分析了三峽工程泄洪時壩下游引航道和兩壩間河段（三峽至葛洲壩）的非恆定波流運動特性，結合遙控自航船模試驗對兩壩間的通航水流條件進行了分析評價，並提出了提高通航流量標準、改善通航條件的相應措施。 -
Using flood progress model and the different discharge of feilaixia reservoir, we can calculate in time the water level and discharge of middle - lower reaches of beijiang, thus increase the accuracy of flood forecast and provide the important technical support for the further research on the optimal dispatch method of f lood control system
其中依據水文學和水力學相結合的洪水演進模型，可根據飛來峽水庫不同的下泄流量，及時計算北江中下遊河道的水面線和下泄流量，提高了洪水預報的精度，為進一步研究防洪體系優化調度方法提供極其重要的技術支撐。 -
Combining with case study, the application conditions of hydrologic meteorology forecast information and flood forecast information in dynamic control of the limit water level during flood seasons are also illustrated. ( 3 ) in order to relieve the contradiction between water discharge in flood seasons and water shortage after flood seasons, the manner of flood operation with fixed limited water level during fixed time should be adjusted
（ 3 ）為改變水庫汛期棄水而汛后又缺水的矛盾局面，調整現行水庫固定時間固定汛限水位的調度方式，利用短期氣象預報和洪水預報信息，在不改變現有防洪標準的前提下研究防洪預報調度方式，實現防洪與興利效益的轉換，提高洪水資源的利用率。
