Simulating nitrate drainage losses from a Walnut Creek watershed field.

This study was designed to evaluate the improved version of the Root Zone Water Quality Model (RZWQM) using 6 yr (1992-1997) of field-measured data from a field within Walnut Creek watershed located in central Iowa. Measured data included subsurface drainage flows, NO3-N concentrations and loads in subsurface drainage water, and corn (Zea mays L.) and soybean [Glycine mar (L.) Merr.] yields. Th...

Tectonically Altered Coal Rank, Boulder Creek Formation, Northeastern British Columbia

Fieldwork during the 1988 season involved investigation of the thermal affects of tectonic movement on vitrinite reflectance near the Quintette Coal Limited mining operation in northeastern British Columbia. Two samples, collected in 1987, from the same seam on either side of a fault, suggested a significant rank increase associated with the stmctwe. These sites were revisited and sampled toget...

Assessing trace-metal exposure to american dippers in mountain streams of southwestern British Columbia, Canada.

To develop a suitable biomonitor of metal pollution in watersheds, we examined trends in exposure to nine trace elements in the diet (benthic invertebrates and fish), feathers (n = 104), and feces (n = 14) of an aquatic passerine, the American dipper (Cinclus mexicanus), from the Chilliwack watershed in British Columbia, Canada. We hypothesized that key differences may exist in exposure to meta...
