Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding. Conversely, concrete is one of the most powerful tools for proper flood control, by means of damming , diversion, and deflection of flood waters, mud flows, and the like.
Much agricultural pollution is exacerbated by surface runoff, leading to a number of down stream impacts, including nutrient pollution that causes eutrophication. In addition to causing water erosion and pollution, surface runoff in urban areas is a primary cause of urban flooding , which can result in property damage, damp and mold in ...
After heavy rainfall events that cause stormwater overflows, contaminated water can impact waterways in which people recreate or fish, causing the beaches or water-based activities to be closed. This is because the runoff has likely caused a spike in harmful bacterial growth or inorganic chemical pollution in the water.
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
A recent scientific study upset gardeners from the United States to Europe by declaring that urban agriculture has a carbon footprint that’s up to six times larger than that of commercial ...

A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain, [1] surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...

There are several types of urban flooding, each with a different cause: Pluvial (flooding caused by heavy rain), Fluvial (caused by a nearby river overflowing its banks), and; Coastal flooding (often caused by storm surges). Different types of urban flooding create different impacts and require different mitigation strategies. [4] [5]
