Instream Flow Assessment: From Holistic Approaches to Habitat Modelling

Habitat Simulation Technique as a Powerful Tool for Instream Flow Needs Assessment and River Ecosystem Management

Instream flow needs (IFN) assessment studies are performed to provide guidelines for stream water management and to assess the impacts of different water projects such as weirs, dams and stream diversions on the available fish habitat. The physical habitat simulation is one of the IFN assessment methods and also a powerful tool in management of river ecosystem that has not become a common metho...

DEMONSTRATION FLOW ASSESSMENT: PROCEDURES FOR DIRECT OBSERVATION INSTREAM FLOW STUDIES Short title: DEMONSTRATION FLOW ASSESSMENT PROCEDURES

The Demonstration Flow Assessment (DFA) method for instream flow evaluation uses direct observation of river habitat conditions at several flows and expert judgement to rank the alternative flows. The DFA method has the advantage of allowing long river reaches to be assessed at relatively modest cost. However, past applications have often lacked procedures and documentation to assure that resul...

Response of a Brook Trout Population and Instream Habitat to a Catastrophic Flood and Debris Flow

—In June 1995, a massive flood and debris flow impacted fish and habitat along the lower 1.9 km of the Staunton River, a headwater stream located in Shenandoah National Park, Virginia. In the area affected by debris flow, the stream bed was scoured and new substrate materials were deposited, trees were removed from a 30-m-wide band in the riparian area, and all fish were eliminated. In the area...
