1·Roof runoff water quality was affected by rainfall, rainfall intensity, roof material, season and air temperature.

屋面径流水质主要受降雨量、降雨强度、屋面材料、季节和气温的影响。

2·The rain runoff water quality in Shanghai was monitored and the main pollution factors influencing the water environment were investigated.

通过对上海市雨水径流水质的监测，以及对其污染主要影响因素与污染程度的分析，掌握水质特性及其变化规律。

3·The concentrations of nitrogen and phosphorus in runoff water is higher than that in infiltrated water. Surface runoff is the main way of nitrogen and phosphorus losses under the condition.

径流液中各形态氮、磷浓度远高于渗漏液，而两种流失方式下排水量差异不显著，故地表径流是该条件下氮素和磷素流失的主要方式。

4·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。

5·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。

6·Corn uses less water than rice and creates less fertilizer runoff.

与水稻相比，玉米耗水更少，产生的化肥径流也更少。

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

沿海水域的亮度差异可能是由于其他因素所导致，包括淡水径流，强劲的水流，水的深度以及清澈度。

8·Phosphorus pollution comes from multiple sources, including fertilizer and manure that enter the water through runoff.

磷污染有多个来源，包括化肥和粪肥通过径流进入水源。

9·Other environmental pressures to the reef and its ecosystem include water quality from runoff, climate change accompanied by mass coral bleaching, and cyclic outbreaks of the crown-of-thorns starfish.

其他对于大堡礁及其生态系统的环境压力来自径流的水质问题，伴随着大规模珊瑚白化的气候变化以及棘冠海星的周期性爆发现象。

10·Some time in the coming decades, the shrinking of glaciers will cause a drop in the level of glacial runoff, reducing the supply of water to urban Chileans.

在未来几十年里的某个时候，冰山的消融会减少冰山径流，从而减少对智利城市居民的用水供应。
