<br />The climatic characteristics are defined and were determined as
<br />follows:
<br />
<br />Mean annual precipitation (p), In inches, was determined for each
<br />basin from Theissen polygons for all USWB3 stations in the study area
<br />which had complete records for the period 1921-56 or directly from maps
<br />published in the USWB series (Climates of the ,States) for small drainage
<br />areas.
