1. Water absorption is greatly reduced; consequently runoff is increased, resulting in accelerated erosion rates. 吸水性大大降低了；因此，径流增加，导致了侵蚀率的增加。
2. Recent studies of ancient Maya water management have found that the urban architecture of some cities was used to divert rainfall runoff into gravity-fed systems of interconnected reservoirs. 最近对古玛雅水资源管理的研究发现，一些城市的城市建筑被用来分流降雨径流到相互连接的水库的重力补给系统中。
3. There will be a runoff between these two candidates on December 9th. 在12月9日，将举行这两位候选人的决胜选举。
4. Another hypothesized human-related cause is fertilizer runoff. 另一个假设的与人类有关的原因是化肥流失。
5. This scenario begins with the planting of hyperaccumulating species in the target area, such as an abandoned mine or an irrigation pond contaminated by runoff. 这种情形始于在目标地区（如废弃矿井或被污水污染的灌溉池）种植超积累物种。
