 In stark contrast to hard engineering, employed with the sole purpose of improving navigation, industrial and commercial uses of the river, soft engineering takes a multi-faceted approach, developing shorelines for a multitude of benefits and incorporating consideration of fish and wildlife habitat.Tasked with the responsibility to construct and maintain United States Federally authorized coastal civil works projects, the U.S. Army Corps of Engineers plays a major part in the development the principles of coastal engineering as practiced within the U.S.In part due to degradation of coastline across the United States, the core has since updated its coastal management practices with an increases emphasis on computer-based modeling, project upkeep, and environmental restoration.
