pooling and ponding
英文解释：Ponding means the excessive accumulation of water at low-lying areas that remains after 48 hours after the end of rainfall ; pooling is grouping together of various items or resources (sand, dirt and the list is much longer).
中文解释：（路面）淤积（pooling）和积水（ponding）
原文举例：
Ponding and pooling are no strangers to Ottawa streets during snowmelts. But during the spring, summer and fall, it’s just as normal to see them reappear on our streetscapes after major rain events and thunderstorms.
在渥太华的街道上，在积雪融化的时候，积水和淤积并不陌生。但在春季、夏季和秋季，在大雨和雷暴之后，它们再次出现在我们的街道上，这是很正常的。
storm water or stormwater
英文解释：surface water in abnormal quantity resulting from heavy falls of rain or snow；storm water is water that comes from precipitation and ice/snow melt
中文解释：下雨或雪后融化形成的后的地表水
原文举例：
Some areas of the city are more vulnerable to significant rain events due to geographical features in those areas. As a result, some catch basins in those areas are equipped with inlet control devices (ICDs), or commonly known as restrictors.
ICDs help manage stormwater when the storm sewer is beyond capacity. They help prevent stormwater pipes from surcharging and backing up into people’s basements. Water is contained on the surface where it will pond but gradually recede as the rainfall stops
由于一些地区的地理特征，这些地区更容易受到重大降雨的影响。因此，这些地区的一些集水区都配有进口控制装置(ICDs)，或通常称为节流器。
当雨水下水道超出容量时，综合控制系统可以帮助管理地表雨水。它们有助于防止雨水管道超载和回流到人们的地下室。雨水被先控制在地表面，然后形成积水，但随着降雨停止地表雨水会逐渐退去。
