| 1. | Stochastic model for flood peak discharge and multistation flood volume 洪水多站峰量同时模拟的随机模型 |
| 2. | Meanwhile , the flood peak fell off ceaselessly , witch indicates that the new conformation descended greatly Sin以上,这比现代洪水时期河水位一般上升1 zm左右明显高。 |
| 3. | It has not only the effect of deducting flood peak and retenting flood but also a little decrease of the volume of floods into the yellow river 不同时期堤防的建设标准及河道条件不同,夹滩地区的滞洪作用也不同。 |
| 4. | A flood peak cut coefficient ( ) is proposed to measure the affection of the flood hydrograph for the risk calculating of the flood discharge 本文分析了洪水过程这一不确定性因素,并用洪峰削减系数将洪水过程的不确定性量化。 |
| 5. | The yarkant river flood dynamic rule is extremely complex , extremely high rises the speed by it , the unusual high flood peak value is world famous 摘要叶尔羌河洪水动态规律极为复杂,以其极高的起涨速率、异常的高洪峰值闻名于世。 |
| 6. | Rain in central henan province , in the upper reaches of the river , is pushing the third flood peak of the year towards wangjiaba , a crucial hydrological station in anhui , the local drought prevention and flood control office said yesterday 当地抗旱防汛办公室昨天说:河南省中部地区普降大暴雨.在长江上游,会推动第三次洪峰侵袭安徽省重要的王家坝水文站 |
| 7. | Terraces on slope land delete the conditions of causing soil and water loss . ponds , cistens , water cellars enhance surface water use efficiency , warping dams can store flood , decrease flood peak , retain sediment , and conserve water 坡地修梯田消除了产生水土流失的条件,蓄水池、旱井、水窑提高了对地表水资源的利用率,淤地坝具有蓄洪水、削洪峰、拦泥沙、涵养水源的作用。 |
| 8. | The probability density function of net rainfall relative errors , flood peak discharge relative errors and the time error of the forecasted flood peak are calculated by the model developed 通过建立洪水预报误差分布的最大摘模型,计算出9座典型水库洪水预报的净雨相对误差、洪峰流量相对误差和峰现时间预报误差的概率密度函数,并将其概率密度函数曲线与正态分布曲线进行比较。 |
| 9. | The velocity of flood propagation was great and flood deformation was slightly when flood peak increase to bank full discharge . as the discharge increased to 2 - 2 . 5 times of bank full discharge the velocity reduced to the lowest value and the greatest flood deformation occurred 当洪峰流量接近平滩流量时洪水传播速度最快,洪峰变形最小,当洪峰流量约是平滩流量的2 2 . 5倍时,洪水传播速度最慢,洪水变形最大。 |
| 10. | The simulation model for flood routing along the river channel is studied , and a simulation system is established on computer base . the model is applied to flood peak operation on the upper section of wei river in shaanxi , and the visualization is realized 研究了河道洪水演进仿真系统设计和具体实现方法,特别是建立了渭河陕西段上游错峰调度子系统,并实现了洪水演进过程的可视化;这一子系统具有创新性和实用性。 |
