An assemblage of fossil sockeye salmon was discovered in Pleistocene lake sediments along the South Fork Skokomish River, Olympic Peninsula, Washington. The fossils were abundant near the head of a former glacial lake at 115 m elevation. Large adult salmon are concentrated in a sequence of death assemblages that include individuals with enlarged breeding teeth and worn caudal fins indicating mi...

Coastal systems around the globe are being re-integrated with adjacent river to restore natural hydrologic connection riparian wetlands. The Mississippi River sediment diversions or reconnections one such tool combat high rates of wetland loss in coastal Louisiana, USA by providing freshwater, sediment, and nutrients. There has been some disagreement published literature whether re-establishing...

The Tongariro River supports a world renowned trout fishery and a nationally important hydroelectric power scheme which has caused profound changes to the river's flow regime and some minor changes to its fishery. Specifications for the regulated compensation flow in the lower river, whilst originally intended to protect the fishery, constrain electricity generation and fail to address all requ...

background: this study compared the early success, complication and patient satisfaction rates of modified extraperitoneal radical cystectomy (mainz ii urinary diversion) with standard intraperitoneal radical cystectomy (continent ileocecal urinary diversion) in a group of patients with muscle invasive urothelial carcinoma of the urinary bladder. methods: from september 2009 until november 2013...

The Woonasquatucket River in North Providence, RI, is a postglacial river flowing approximately 18 miles from its headwaters in North Smithfield, RI, to Providence, RI, where it joins the Moshassuck River and enters the Providence River. In 1776, a powder mill was constructed along the river to support the Colonies’ efforts in the American Revolutionary War. The powder mill exploded in 1779, se...

Small dams for hydropower have caused widespread alteration of Central American rivers, yet much of recent development has gone undocumented by scientists and conservationists. We examined the ecological effects of a small hydropower plant (Doña Julia Hydroelectric Center) on two low-order streams (the Puerto Viejo River and Quebradon stream) draining a mountainous area of Costa Rica. Operation...

River-blocking landslides exert a deep impact on mountain range landscapes and the organization of catchments. A blocked river diverted to another watershed modifies both original transferred drainage networks up- downstream. Using western Pyrenees examples, geological geomorphic framework with diagnostic criteria detect diversion by is presented, including identification elbows diversion, erod...

Flow structures at a river diversion juncture are complex and have been studied extensively. Their impact on the juvenile salmon entrainment into side channel, however, is less investigated, based mostly empiricism. In this study, Eulerian fish tracking model developed used in conjunction with 3D flow solver to quantitatively evaluate implications of characteristics typical junctures entrainmen...
