The premises of the simulation are that the runoff from upreach is 7.8× 108m3/a and the means of economization on water is in effect. When studied it was thought firstly the water for the lake area and the living plant of the oasis, then for forest-sod irrigation and farmland irrigation.

模拟计算是以上游下泄水量7.8×10~8m~3／a为前提条件，在实行节水措施，完善供水系统的情况下，首先满足维持和恢复一定规模湖泊面积，保证绿洲植被正常生长所需水量，然后考虑林草灌溉用水和农田灌溉用水量。

The theory and basic assumption of distributed hydrological for water resources assessment under various environment is introduced to solve the problems of restoration distortion and restoration invalidation in traditional method. A method, namely UCMV (upreach for calibration and mid-reach for validation), based on parameter calibration by up-stream runoff station and verification by validation midstream station is developed.

为解决变化环境条件下水资源评价中的&还原失真&和&还原失效&问题，本文提出基于物理参数的分布式水文模型用于变化环境下水资源评价方法的原理和假定，以及基于此原理利用上游测站流量进行模型参数率定和中游测站进行验证（简称UCMV， Up-reach for Calibration and Mid-reach for Validation）的水资源评价新方法。

The middle and lower parts of woodland and grassland had higher soil water contents during rainy season, which resulted from smaller evapotranspiration and more infiltrated water with a lower gradient. However, upslope runoff infiltration was another reason for hillslope with a lower cover ratio, such as bare land.

雨季林草地坡中下部土壤水分含量较高的原因，可能主要与其蒸散较小且坡度较缓导致入渗水量较多有关；但是对于植被覆盖度较低的坡地，坡中下部土壤水分含量较高还与上方来水有较大的关系。

Results show that impervious urban land surface runoff model includes 6 critical parameters, which are depression storage, Manning's n, maximum buildup possible, buildup rate constant, washoff coefficient, and washoff exponent.

为了研究城市不透水下垫面的降雨径流过程和污染负荷，以屋面为例，选择径流管理模型SWMM，采用独立场次实测数据，应用基于不确定性分析的HSY算法和Monte Carlo采样方法对模型中的水文水力和水质参数进行识别和验证。

A simulation of storm runoff treatment with three types of subsurface flow wetlands of the pilot-scale bed of blank plant,Phramites communis and Zizania caduciflora was studied.

进行了3种人工潜流湿地(无植物空白床、芦苇床、茭草床)控制暴雨径流中氮、磷浓度的冲击负荷试验，考察了潜流湿地对氮、磷的去除效果及其耐冲击负荷能力。

Ecologically, the river-like shape of the Jungle Park acts as a filtration system collecting water runoff from the urban portion of the site, culminating in a waterfall at the rear of the site

从生态学角度看，河流状丛林公园还扮演着过滤系统的角色，从开发区的城区部分流来的径流汇集到工地的后部，形成一个瀑布。

Based on the result of field artificial rainfall experiments on 60m length slopes,sedi-ment delivery is consisted of raindrop impact,slope runoff and rill flow delivery.Accord-ing to their functions,rill was ranked firstly then slope run off,and last raindrop impact.

通过野外60m坡面人工降雨实验及过程结果分析可知：输移由雨滴击溅、坡面径流和细沟输移三部分组成，按作用大小来排，细沟流占第一位，坡面径流占第二位，雨滴击溅最小。

More than 170 hectares were afforested, reducing water runoff from the hillsides.

超过170公顷的土地已植有林木，以减少雨水从山坡流下。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
