1·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。
2·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。
3·Local issues range frompollution and siltation due to coastal runoff to an increase in the harvest ofsome seaweeds, fueled by the demand for natural food.
局部问题包括从由海岸径流引起的污染及淤积到因对天然食品的强烈需求而引发对海草采捞的增大。
4·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。
5·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。
1·Runoff and tidal range are the main factors influencing the effects of dilution and dispersion.
迳流和潮差是影响污水稀释扩散效果的主要因素。
