River runoff is an important influence for many coastal oceanographic processes, but in places of the world much flow ungauged rivers. The model developed here uses historical relationship between precipitation and applies it to areas produce estimate flow. combination gauged then used total freshwater discharge affecting waters British Columbia. A distinction made pluvial nival-glacial watersheds accommodate their widely different regimes within study area. Calendar Year Water variants are...
Abstract Drought is common in rivers, yet how this disturbance regulates metabolic activity across network scales largely unknown. often lowers gross primary production (GPP) and ecosystem respiration (ER) small headwaters but by contrast can enhance GPP cause algal blooms downstream estuaries. We estimated metabolism a nested of 13 reaches from to the main stem Connecticut River 2015 through 2017, which encompassed pronounced drought. During drought, ER increased, with greater enhancement...
The U.S. Geological Survey (USGS) deployed a temporary monitoring network of water-level and barometric pressure sensors at 224 locations along the Atlantic coast from Virginia to Maine continuously record timing, areal extent, magnitude hurricane storm tide coastal flooding generated by Hurricane Sandy. These records were greatly supplemented an extensive post-flood high-water mark (HWM) flagging surveying campaign November December 2012 involving more than 950 HWMs. Both efforts undertaken...
There are few computer models that can simulate winter freeze–thaw conditions and spring snowmelt hydrology for agricultural tile drained lands. DRAINMOD, which is used widely to drainage flows, has not been extensively applied during colder periods in eastern Canada. This study analyzes the performance of DRAINMOD surface runoff subsurface predictions southern Quebec snowmelt. The model was tested with five years field data. found be adequate predicting hydrology, except at one site. It...
Tile drainage is a widely adopted water management practice in the eastern Canadian provinces of Québec and Ontario. It aims to improve productivity poorly drained agricultural fields. Nevertheless, studies have also shown that subsurface significant pollution pathway surface water. This study was undertaken evaluate effect tile drain spacing on runoff, flows, phosphorus (P) loss from two tile-drained fields located near Bedford, Québec. Field data were used with DRAINMOD model, developed...

Water-quality conditions were assessed to evaluate potential effects of road-deicer applications on stream-water quality in four watersheds along Interstate 95 (I-95) southeastern Connecticut from November 1, 2008, through September 30, 2009. This preliminary study is part a four-year cooperative by the U.S. Geological Survey (USGS), Federal Highway Administration (FHWA), and Department Transportation (ConnDOT).

Water quality was characterized at three tributary watersheds to the Nepaug Reservoir-Nepaug River, Phelps Brook, and Clear Brook-from October 1998 through September 2001 document existing water-quality conditions evaluate potential future effects of removal sand gravel from areas watershed. Some operations may include vegetation top soil steepening slopes. Routine water samples collected monthly in all were analyzed for nutrients, organic carbon, major ions, fecal indicator bacteria....
