Tag: flood plain

A floodplain or flood plain is an area of land adjacent to a stream or river that stretches from the banks of its channel to the base of the enclosing valley walls and experiences flooding during periods of high discharge. It includes the floodway, which consists of the stream channel and adjacent areas that actively carry flood flows downstream, and the flood fringe, which are areas inundated by the flood, but which do not experience a strong current. In other words, a floodplain is an area near a river or a stream which floods when the water level reaches flood stage.

“SWMMing” Through Stormwater Management Challenges

Urban stormwater ruins picnics and ballgames, raises floods, snarls traffic, threatens safety, wreaks destruction, costs cities millions in damage and disruption–and those are among the relatively short-lived effects. Stormwater runoff is also the leading source of water-quality problems nationwide, carrying sediment and other pollutants to lakes, streams, coastal estuaries, and

These two slope stabilization projects had the same goals: to protect the slopes from water-related erosion with engineering techniques and materials that made them look natural and remain maintenance-free for the long term. But the similarities end there. One project restored a fragile stream and protects it from stormwater flow.

In one part of the United States, municipal officials discover the original mapping of a floodplain is incorrect, setting the stage for a potential crisis following a significant weather event. Elsewhere, an engineer seeks answers to help mitigate frequent flooding. Sizing storm systems correctly is a challenge for another engineering
