The spatial variability of runoffarea has a great effect on the time-space input of sediment supply into rivers.
流域产流面积的空间变化对其产沙、供沙的时空输入特性具有制约作用。

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。

Differences in brightness in coastal area waters may be due to other factors, including freshwater runoff, strong currents, and water depth and clarity.
