...Mohamed H. Nour; Daniel W. Smith; Mohamed Gamal El-Din; Ellie E. Prepas This study is an effort to incorporate low-cost time-variant remote sensing (RS) information in watershed-scale total phosphorus (TP) modelling. Four watershed subdivisions were delineated to assess the impact of watershed...

... and surrounding uplands as it relates to rain and snow interception and evapotranspiration;; and connectivity of the wetland to the regional hydrological network. Key factors that influence boreal wetland phosphorus (P) budgets are: spatial and temporal variability in the water table as they relate to reduction...

...Ellie E. Prepas; Janice M. Burke; Gordon Putz; Daniel W. Smith This study examined total dissolved (TDP) and particulate phosphorus (PP) concentration and export in nine headwater streams draining Boreal Plain forests in Alberta, Canada, during the growing season and autumn before and in the first...

... of this study was to estimate the ammonium adsorption capacity of clinoptilolite when being loaded with wastewater. Phosphorus and potassium sorption, ammonium desorption with tap water, and clogging were also studied. The study was performed by column experiments. Results of the investigation showed...
