Description:
We have conducted research to find a faster, simpler, less expensive way to create runoff (i.e., runoff-depth) contour maps using automated procedures. ur goal was to produce maps as accurate as those produced manually by the U.S. Geological Survey. e developed eight procedures based on simple water balance methods and regression techniques to produce a map for our test case (Water Year 1984) for the northeastern United States. he simplest procedure involved automated contouring based upon linear interpolation of gaged runoff. he other seven procedures involved linear interpolation of 1) gaged runoff watershed centroids, and 2) runoff estimated at a set of geographic locations (precipitation stations). e determined that two of these procedures produce the most accurate maps on a regional basis. hese two procedures compare favorably to a manual method. he results of our work indicate that simple automated procedures can produce runoff contour maps with regional accuracies roughly equivalent to those produced by manual methods.
