Vadose Zone Response to Pumping in Unconfined Aquifers
(University of Waterloo, 2011-09-30)The interaction between drainage from the variably saturated zone above the water table, and the response of an unconfined aquifer to pumping has been the source of debate for many decades. While various field tests (Nwankwor ... -
The Value of Agricultural Census Data in Carbon Cycle Studie
(University of Waterloo, 2011-05-24)Agricultural census data have been identified to possess the potential to provide constraints on carbon uptake by croplands at the regional scale. In this study, we build on previous efforts and further assess this potential ... -
Variations and Sources of Atmospheric CO2 Measured at East Trout Lake, Canada
(University of Waterloo, 2016-01-15)Reducing uncertainties in projections of surface emissions of major greenhouse gases (GHGs) including CO2 relies on continuously improving our scientific understanding of the exchange processes between the atmosphere and ... -
Visualising data distributions with kernel density estimation and reduced chi-squared statistic
(Elsevier, 2017-11-01)The application of frequency distribution statistics to data provides objective means to assess the nature of the data distribution and viability of numerical models that are used to visualize and interpret data. Two ... -
Water Demand Forecasting Model Application
(University of Waterloo, 2019-01-29)Forecasting water demand requires quantifying potential relationships between relevant statistics and ambient conditions such as water price and weather. Dr Enouy (2018) demonstrates that discrete histograms can be ... -
Woodchip Biofilters for Treatment of Particulate Phosphorus in Agricultural Runoff
(University of Waterloo, 2017-07-07)Woodchip filters have received attention in recent years for their ability to sustain denitrification activity across multiyear time frames. However, in most freshwater aquatic ecosystems, phosphorus (P) rather than nitrogen ... -
Worldwide retention of nutrient silicon by river damming: From sparse data set to global estimate
(American Geophysical Union, 2014-08-13)Damming of rivers represents a major anthropogenic perturbation of the hydrological cycle, with the potential to profoundly modify the availability of nutrient silicon (Si) in streams, lakes, and coastal areas. A global ...
