地下河

采用湖南洛塔地区屋檐洞地下河系统降水&径流资料训练BP人工神经网络，建立了该系统的径流预测模型。

This paper presents a forecasting model of runoff to Wuyandong subterranean stream system by BP ANN based on the data of precipitation and flux in Luota , west Hunan .

除主体工程外，坝体上部有厚110m的松散堆积作为天然坝体。通过实地勘测、钻探及物探等成果资料和地下河试堵工程观察分析，上部松散体主要由滑坡堆积而成。

In addition to main project , there is incompact deposit of 110m in the thickness being as natural dam , which consists of landslide accumulation through data analysis of reconnaissance on the spot , drilling , geophysical exploration and observation on trying to plug the subterranean stream .

地下河距离上面的城市街道只有几英尺。

The groundwater is only feet beneath the city streets .

本溪水洞为我国东北中高纬度地区规模最大的地下河洞穴，全长在5000m以上，已探测长度3658m。

Benxi water cave is the biggest subterranean cave developed in mid high latitude area of northeast China , with over 5000m in length , and the explored parts are 3685m long .

针对岩溶水资源的特征，作者认为，改变传统定量评价的思维、引进现代水文学理论方法和充分利用3S技术，是解决地下河系统水资源定量评价的主要出路。

Against the characteristic of the karst water resource , the thinking of traditional quantitative appraisal need to be changed , introduction of theory method of modern hydrology and fully utilization of 3S technology are the main way of quantitative assessment of water resources in subterranean streams .

这主要是因为洞底有地下河，空气湿度较大会溶解一部分C02，且中上层的洞道曲折、洞体较小，利于CO2的积聚。

This is mainly because there are underground river at bottom , the air humidity will be dissolved a large part of CO2 , and the upper hole in the Road twists and turns , a smaller cave , conducive to the accumulation of CO2 .
