- ... Physically based models of lakes require estimates of daily, spatially varied water and nutrient fluxes into the lake from surrounding watersheds. Often, however, only a selected set of streams are periodically (monthly or biweekly) sampled. The objective of this study was to develop and test a method for estimating daily flux of nutrients into a large reservoir using data from sampling of selecte ...

- ... The transport of bioavailable P (BAP) in agricultural runoff can stimulate freshwater eutrophication. Previous research has shown that the amount of P removed by Fe-oxide impregnated paper strips (Fe-oxide strips) is related to the growth of in laboratory incubations. As only one algal type was used, additional assays were conducted to determine if Fe-oxide strips can estimate the potential bioava ...
