Phosphorus concentrations, loads, and yields in the Illinois River Basin, Arkansas and Oklahoma, 1997-2001
Barbara E. Pickup, William J. Andrews, Brian E. Haggard, W. Reed Green
2003, Water-Resources Investigations Report 2003-4168
The Illinois River and tributaries, Flint Creek and the Baron Fork, are designated scenic rivers in Oklahoma. Recent phosphorus increases in streams in the basin have resulted in the growth of excess algae, which have limited the aesthetic benefits of water bodies in the basin, especially the Illinois River and...

Using sensitivity analysis in model calibration efforts
Claire R. Tiedeman, Mary C. Hill
2003, Book chapter, Proceedings of the International Workshop on Uncertainty, Sensitivity, and Parameter Estimation for Multimedia Environmental Modeling
In models of natural and engineered systems, sensitivity analysis can be used to assess relations among system state observations, model parameters, and model predictions. The model itself links these three entities, and model sensitivities can be used to quantify the links. Sensitivities are defined as the derivatives of simulated quantities...

Quantifying migratory delay: A new application of survival analysis
Theodore Castro-Santos, Alex Haro
2003, Canadian Journal of Fisheries and Aquatic Sciences (60) 986-996
Statistical techniques commonly used in fish passage research fail to adequately quantify delays incurred at obstacles, or the effects of modifications to those obstacles on passage rates. Analyses of telemetry data describing these effects can be misleading, particularly when passage route of some individuals is not established (e.g., because of...
