When one talks about the Susquehanna River, the topic of flood control is bound to come up.
Flood control is defined as all methods used to prevent or reduce the harmful effects of floods.
Structural approaches to flood control include dams and reservoirs, levees or dikes, floodwalls, modification of stream channels, flood-diversion systems and floodways, and treatment of watersheds. Nonstructural approaches include flood forecasts and early warning systems , and mitigation measures such as land use plans, land development and zoning ordinances, or national building codes. These measures are all examples of flood plain management. A flood plain is the area adjacent to a river or a stream which is subject to flooding. The flood plain is identified by many features including topographic features such as terraces and the relatively flat land next to a stream or river.
