Methods for accurate estimation of net discharge in a tidal channel
M.R. Simpson, R. Bland
2000, IEEE Journal of Oceanic Engineering (25) 437-445
Accurate estimates of net residual discharge in tidally affected rivers and estuaries are possible because of recently developed ultrasonic discharge measurement techniques. Previous discharge estimates using conventional mechanical current meters and methods based on stage/discharge relations or water slope measurements often yielded errors that were as great as or greater...

2000, Interagency Ecological Program Newsletter (13) 27-33
Delta smelt is a threatened species in the San Francisco Bay Estuary. Pesticide toxicity is a possible cause for the need to list this fish (Bennett and Moyle 1996; Moyle and others 1996). Numerous pesticides are transported into the estuary from area rivers (MacCoy and others 1995). However, there are...

The effects of dissolved gas supersaturation on white sturgeon larvae
T.D. Counihan, Allen I. Miller, M.G. Mesa, M.J. Parsley
2000, Transactions of the American Fisheries Society (127) 316-322
Spill at dams has caused supersaturation of atmospheric gas in waters of the Columbia and Snake rivers and raised concerns about the effects of dissolved gas supersaturation (DGS) on white sturgeons Acipenser transmontanus. The timing and location of white sturgeon spawning and the dispersal of white sturgeon larvae from incubation...

Hydrogeology and simulation of ground-water flow in the Ohio River alluvial aquifer near Carrollton, Kentucky
Michael D. Unthank
1999, Water-Resources Investigations Report 98-4215
The alluvial aquifer near Carrollton, Kentucky, lies in a valley eroded by glacial meltwater that was later part filled with outwash sand and gravel deposits. The aquifer is unconfined, and ground water flows from the adjacent bedrock-valley wall toward the Ohio River and ground-water withdrawal wells. Ground-water-level and Ohio River...
