RMRATE is a computer program for analyzing rating judgments. The program should be useful to practitioners needing to summarize or analyze rating data, and to researchers interested in comparing and evaluating alternative scaling methods.
The method of paired comparison was introduced nearly 150 years ago and is perhaps the most straightforward way of presenting items for comparative judgment. PAIRCOMP administers the paired comparison experiment that presents the pairs of items on the monitor in a unique random order to control for order effects.
As a companion to A Primer on Nonmarket Valuation edited by P.A. Champ, K.J. Boyle, and T.C. Brown (Kluwer Academic Publishers) we developed this website to provide datasets corresponding to each of the nonmarket valuation techniques described in the Primer. We've also included the surveys used to collect the data, the codebooks (explanation of how the data are coded), and links to the publications based on the data. This website should aid...
WEPP:Road predicts the annual average erosion from insloped or outsloped forest roads and predicts the amount of sediment that will leave the buffer.
Disturbed WEPP is a web application which allows users easily to describe numerous disturbed forest and rangeland erosion conditions. The interface presents the probability of a given level of erosion occurring the year following a disturbance. Version 2.0 needs no vegetation calibration.
ERMit is a web application which models erosion on current or proposed forest road. ERMiT allows users to predict the probability of a given amount of sediment delivery from the base of a hillslope following variable burns on forest, rangeland, and chaparral conditions in each of five years following wildfire. The model also predicts the effectiveness of sediment mitigation methods following a wildfire, such as applying mulch or seeding.
Tahoe Basin interface is a customized version of Disturbed WEPP that contains Tahoe-specific soils. It predicts not only runoff and erosion, but also delivery of phosphorus and fine sediment, something of particular concern in the Tahoe Basin.
The Forest Service Peak Flow Calculator predicts peak flood flow rate for a given storm from a small watershed. The model uses Curve Number technology given precipitation and runoff, as from ERMiT, plus other parameters.
The Water Erosion Prediction Project (WEPP) is a computer simulation that predicts soil erosion.  This particular version of the tool predicts soil erosion for the Great Lakes watershed.
VAR stands for Values-at-Risk. The VAR Calculation Tool aids with assessing post-fire values-at-risk, including but not limited to human life and safety, infrastructure damage, and environmental effects.
