1·But only now are some of the DAMS of the colonial era being restored to use, after years of neglect and silting up.
多年失修和淤积后，人们到现在才开始对殖民时代的一些水坝进行维修。
2·Based on the principle of GIS and database system, data model, function modules and agent structure of sediment silting system of watercourse and reservoir zone is designed.
根据GIS、数据库系统的原理，设计实现了河道与库区泥沙淤积系统的数据模型、功能模块和主体结构，成功地将基础数据库进行了入库操作。
3·It need not be thought of silting when medium and small sized water convey canal were designed because of little water drawing and sand quantity.
阐述了中小型输水渠道设计时，由于水库取水含沙量较小，不需要考虑淤积问题。
4·The silting gradually weakened its intensity and transited into scouring state from nearshore to shallow sea area.
由近岸往外，淤积强度逐渐减弱，并过渡为冲刷状态。
5·After impoundment of Three Gorges reservoir, the sediment silting in the reservoir and clear water discharge significantly impact the downstream rive channel.
三峡水库蓄水运用以后，由于库区泥沙淤积，清水下泄，下游河道必然受到影响。
