Surface water qualit: Revisiting nitrate concentrations in the Des Moines River: 1945 and 1976-2001
G.F. McIsaac, R.D. Libra
2003, Journal of Environmental Quality (32) 2280-2289
Recent compilations of historical and contemporary riverine nitrate (NO3) concentrations indicate that concentrations in many rivers in the north-central USA increased during the second half of the 20th century. The Des Moines River near Des Moines, Iowa, however, was reported to have had similar NO3 concentrations in 1945 and the 1980s,...

2003, Report, Heat as a tool for studying the movement of ground water near streams (Cir1260)
Advances in electronics leading to improved sensor technologies, large-scale circuit integration, and attendant miniaturization have created new opportunities to use heat as a tracer of subsurface flow. Because nature provides abundant thermal forcing at the land surface, heat is particularly useful in studying stream-groundwater interactions. This appendix describes methods for...

Michael G. Rupert, Susan H. Cannon, Joseph E. Gartner
2003, Open-File Report 2003-500
Logistic regression was used to predict the probability of debris flows occurring in areas recently burned by wildland fires. Multiple logistic regression is conceptually similar to multiple linear regression because statistical relations between one dependent variable and several independent variables are evaluated. In logistic regression, however, the dependent variable is...
