蓄水

According to the study above and the hydrographical data throughout 2000, the water conservation of forest types in the four main water collection area (Kunaer river, Honghutu river, Gongbiela river and Halatai river) were systematically analyzed and evaluated.

本论文将2000年全年的水文观测数据与流域林型结构及土壤蓄水功能相结合，经过综合分析，针对流域内四个主要支流流域评价森林的水分调节功能。

And according to the characteristics ofunderlaying surface of catchments and that of runoff, the variation of impoundage was takeninto consideration in runoff model.

并通过分析流域下垫面和径流特点，考虑了土壤蓄水容量的变化，进一步认识流域水文循环变化规律，提高了洪水预报精度。

In this dissertation, as for some problems in flood forecast andreservoir regulation, the research had been done based on the special research topic dynamiccontrol on limit water level in flood season using theories of fuzzy optimizing theory,maximum entropy theory, entropy-weighted multi-objective decision making method, geneticalgorithm etc. And the research focused on evaporation calculation, fuzzy description ofcatchraent impoundage, fuzzy similarity calibration method, nolinear watershed concentrationmodel and error distribution maximum entropy model and risk computation of dynamiccontrol reservoir water level in flood season when the flood forecast and precipitation forecastare taken into consideration.

本文从洪水预报和汛限水位动态控制两个研究方向着手，以汛限水位动态控制研究专题的试点水库为工程背景，运用模糊优选理论、极大熵理论、熵权多目标决策法、遗传算法等理论，研究了蒸散发计算和流域蓄水容量的模糊描述、洪水预报模型参数的模糊相似校正方法、流域非线性汇流模型、误差分布的极大熵模型以及考虑洪水预报和降雨预报动态控制水库汛限水位的风险计算方法。

When modeling river system in south of Tianjin, Haihe River participating inflood discharge only in two conditions for it's special situation, in order to washingout rivers and reducing flood discharge pressure of Duliujian River.

南系蓄水和洪水调度数值模拟中，考虑了海河横贯天津市区的特殊地理位置，只有二十年一遇洪水和五十年一遇洪水工况海河才参与泄洪，借以冲刷海河河道并分担独流减河的泄洪压力。

The golf course sits atop a deep portion of the Ogallala aquifer: water is reached at 150ft.

球场坐落在奥加拉拉蓄水层的上面，地下150英寸就有水，含水沙层有800英寸。

This aquifer was named the Ogallala aquifer after the Ogallala Sioux Indians, who once inhabited the region.

这个蓄水层因曾经在这里定居过的奥加拉拉苏族印第安人而得名，被称作奥加拉拉蓄水层。

The Ogallala Aquifer, one of the world's largest stores of groundwater, covers 225,000 square miles beneath parts of eight U.S.

奥加拉拉蓄水层是全球较大的地下水储层，面积225000平方公里，涵盖了美国德克萨斯州至南达科他州八个州的地下土层，是该国五分之一农田的灌溉源。

The High Plains Ogallala aquifer, which runs 1 300 miles from Texas to South Dakota, is drawn down eight times faster than nature refills it.

从得克萨斯州到南达科他州绵延 1 300英里的奥加拉拉高原的蓄水层下降速度比自然补充的速度快8倍。

The Ogallala aquifer is a sandstone formation that underlies some 583,000 square kilometers of land extending from northwestern Texas to southern South Dakota.

奥加拉拉蓄水层属于砂岩结构，在从德克萨斯州西北到南达科塔州的地下绵延了583000平方公里。

Ogallala water has enabled the High Plains region to supply significant amounts of the cotton, sorghum, wheat, and corn grown in the United States.

奥加拉拉蓄水层支撑了北美大平原地区美国棉花、高粱、小麦、玉米的灌溉需求。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
