TECHNICAL PAPERS

摘要

In two papers, Lerch et al., analyze trends in atrazine, acetochlor, alachlor, metolachlor, and metribuzin concentrations and loads in Goodwater Creek Experimental Watershed from 1992 to 2006, and conduct a retrospective assessment of the potential aquatic ecosystem impacts. Spademan Jones et al., show how turbidity can be used to develop high frequency time series for total suspended solids and total phosphorus. Saleh et al., calculate mass loadings for four pesticides in two watersheds with different land uses in the Central Valley, California, by using two parametric models: (1) the Seasonal Wave model (SeaWave), and (2) the Sine Wave model.
