Diversions lowered the lake level, increased the salinity, changed the availability of aquatic habitats, and altered t...
Diversion (i.e. extraction) of water from rivers and estuaries can potentially affect native wildlife populations if operation is not carefully managed. For example, open, unmodified water diversions can act as a source of injury or mortality to resident or migratory fishes from entrainment and impingement, and can cause habitat degradation and fragmentation. Fish-protection devices, such as ex...
PURPOSE We present a single institute experience of the four most widely used diversions after cystectomy in 281 patients, with an evaluation of the association between clinical factors, complication rates, functional results, and metabolic complications. MATERIALS AND METHODS Between 1990 and 2005, 281 consecutive cystectomies were performed at our institute. Four different diversions were o...
potential to adversely affect the recreational, aesthetic, and ecological resources of mountain streams. The ability to predict channel response to flow diversion can help project designers minimize adverse impacts and design appropriate mitigation measures. Toward this end, we use insights gained from detailed case studies of Lake Fork and Rock Creek – two diverted streams in the Uinta Mountai...
