CONCEPTS: A Process-Based Computer Model of Instream and Riparian Processes
Publication: World Environmental and Water Resource Congress 2006: Examining the Confluence of Environmental and Water Concerns
Abstract
Channelization and floodplain development have disturbed many stream systems throughout the US. Channels have responded through incision and planform adjustment, discharging large quantities of fine sediments that are a leading source of river and stream impairment. Many federal, state, and local organizations are active in restoring damaged channel systems. A particular challenge we face today is the lack of integrated, comprehensive modeling tools to evaluate the long-term response of restored stream-riparian corridors. The CONCEPTS computer model has been developed to evaluate stream-corridor restoration designs. CONCEPTS simulates channel evolution by tracking bed changes and channel widening. It can predict the dynamic response of flow and sediment transport to instream structures. Recently, technology from the USDA-ARS Riparian Ecosystem Management Model (REMM) has been integrated with CONCEPTS. The integration has resulted in a comprehensive stream-riparian corridor model that can assess the effects of riparian buffer systems and forests on stream stability. Three studies using CONCEPTS are presented to demonstrate the capability of CONCEPTS to simulate channel morphology and response in diverse environments.
