Modelling the Effects of Climate Change on the Surface and Subsurface Hydrology of the Grand River Watershed
(University of Waterloo, 2010-05-06)A numerical modelling analysis of climate change’s precipitation effects on the long-term, averaged surface and subsurface hydrology of the Grand River Watershed (GRW) was undertaken in order to assess possible areas of ... -
Multi-decade comparison of groundwater nitrate in the southern Nottawasaga River Watershed
(University of Waterloo, 2016-08-25)The Nottawasaga River Watershed is host to the Lake Algonquin Sand Aquifer (LASA), an unconfined aquifer that consists of glaciolacustrine sands and provides water supply to rural residents, for household use, and for ... -
Numerical Simulation of Road Salt Impact at the Greenbrook Well Field, Kitchener, Ontario
(University of Waterloo, 2002)Chloride concentrations at the Greenbrook well field in Kitchener, Ontario, have been steadily increasing over the past several decades and may soon pose a threat to drinking water quality. Drinking water limits at some ... -
Preparative isolation, fractionation and chemical characterization of dissolved organics from natural and industrially derived bitumen-influenced groundwaters from the Athabasca River watershed
(Elsevier, 2021-07-10)Recent analytical advances have provided evidence that groundwater affected by oil sands process-affected water (OSPW) is reaching the Athabasca River at one location. To understand and discriminate the toxicological risks ... -
Quantification of the Long-Term Effects from Nutrient Reductions on Groundwater Nitrate Concentrations in an Agricultural Setting
(University of Waterloo, 2008-06-06)The Ontario Nutrient Management Act (2002) recommends agricultural Beneficial Management Practices (BMPs) that involve reductions in nutrient applications of nitrogen (N) to fields to improve underlying groundwater quality, ... -
Quantifying the Groundwater Component within the Water Balance of a Large Lake in a Glaciated Watershed: Lake Pyhäjärvi, SW Finland
(University of Waterloo, 2012-01-20)Accurate estimates of the amount of groundwater entering a lake on a yearly basis may provide valuable information for assessing contaminant loadings such as nutrient mass fluxes and the subsequent contribution of groundwater ... -
Simulating the Predevelopment Hydrologic Condition of the San Joaquin Valley, California
(University of Waterloo, 2009-09-23)The San Joaquin Valley is part of the Great Central Valley of California, a major agricultural centre and food supplier for the United States. This area has significant water management concerns given the very high water ... -
Studies of Headwater Brook Charr (Salvelinus fontinalis) Populations in Southern Ontario affected by Groundwater Extraction
(University of Waterloo, 2010-01-13)Habitat conditions, use and preference, size-at-age, density and condition were assessed for headwater brook charr (Salvelinus fontinalis) populations in streams in Southern Ontario where water extraction was occurring. ... -
Using Numerical Models for Managing Water Quality in Public Supply Wells
(University of Waterloo, 2013-08-30)Groundwater models can be useful tools to support decisions regarding the management of public water supply wells. Scientific progress and the availability of increasingly powerful computer resources provide a continuous ...
