Abstract: A post-audit study was made of a predictive water quality model. An analytical model using annually averaged parameters is in good agreement with recent data. The model uses an analytical loading function, first-order ...

Abstract: Trapping efficiency (TE) is defined as the percent of particles that are retained within an impoundment. TE can vary from

Abstract: The response of a northeastern U.S. hardwood forest to wet and dry deposition of hydrogen ion and sulfate deposition was performed using the hydrobiogeochemical, lumped‐parameter Terrestrial Aquatic Model for Ecosystems ...

Abstract: A small field site adjacent to a lake in Amana, Iowa was used to investigate the fate of nitrate fertilizer in the unsaturated zone. The fertilizer was applied to a barren plot, a plot planted with corn, and a plot planted ...

Abstract: Phytoremediation is an emerging technology for degradation of organic chemicals. The potential of phytoremediation in the cleanup of contaminated sites and prevention of non-point-source pollution was examined with the ...

Abstract: The Trickle‐Down model has been developed and applied to Vandercook Lake, Wisconsin, for an acidic deposition assessment. Three years of field data were simulated. Field data of lake stage and groundwater level at the ...

Abstract: Diel dissolved oxygen (DO) concentrations and temperature were sensed at high-frequency and modeled in an eastern Iowan stream, Clear Creek, in an agricultural setting. The magnitude of the diel changes in DO and temperature ...

Abstract: Deep‐rooted trees planted as a buffer zone can intercept runoff and eroded sediments, thus reducing non‐point‐source pollution due to agricultural chemicals. In this study,

Abstract: Over the past decade, water-centric research has increasingly taken into consideration the interactions between the water cycle and the social, economic, and biogeophysical processes that drive watershed dynamics. In ...
