侵蚀

Using environmental radionuclide 210Pb to study the soil erosion and sediment had great application value and potential. When the nuclide was settled on the surface with atmosphere, it was absorbed by the soil particle quickly. The soil erosion rate on the scale of 100 years was traced through the remotion of nuclide in soil and its regular distribution nude.

利用环境放射性核素210Pb来研究土壤侵蚀和沉积具有很大的应用价值和潜力，当核素随大气沉降到地表时，迅速被土壤颗粒吸附，通过其在土壤间的移动和有规律的分布模式可以示踪100年尺度上的土壤侵性速率。

This model introduces a concept of unsaturated sediment transport, reflecting the variation of rill erosion along the distance.

该模型引入了非饱和输沙的概念，能够反映沿程细沟侵蚀的变化规律。

Riprap-- Boulders or loose stones placed in a hollowed out culvert area protect soil underneath from erosion, while slowing water flow.

抛石-大石或放置在松散石头掏空涵洞区保护土壤免受侵蚀下，同时减缓水流。

It is because of this that the highest ground in New Orleans, counter-intuitively, is along the riverfront, one of the only areas of town not to flood after Hurricane Katrina.

拒马河上游地区位于河北太行山区北部，是河北省重要的水源涵养地之一，生态环境有着天然的脆弱性，属于轻度侵蚀防护区。

When Sinlaku hit Taiwan during September 12-15, 2008, the extremely torrential rain made Hou-Fong Bridge, located in downstream of Shi-Gang Dam, broken at around 6:50 p.m. on September 14, 2008. In this study, the case was applied to investigate the factors which resulted in the typhoon flood scour disaster and the disaster prevention mechanism, including the general scour of upstream and downstream river banks, the riverhead erosion and constriction scour, the free fall of broad-crested weir effect caused by water-pipe protection engineering, the disaster prevention and response of the bridge care and management unit, and the examination, timing and procedure of bridge block.

中文摘要本研究系以97年9月12日至15日强烈台风辛乐克侵袭台湾期间，所降下的超大豪雨造成位在大甲溪石冈坝下游后丰大桥於9月14日下午6点50分左右发生断桥事件为例，探讨台洪冲刷灾害成因与防灾应变机制，包含上下游河道之一般冲刷、河道向源侵蚀与束缩冲刷及位於桥梁上游约20公尺处之自来水干管保护工所产生宽顶堰跌水效应等影响，并检讨桥梁养护管理单位於断桥发生前防灾应变处置方式及台洪期间之巡查检测、封桥时机与封桥作业流程等等相关因应作为。
