Future research
Fulfilling the Corps mission to provide flood damage reduction, predict watershed water quality, and to restore safe
drinking water requires continuous improvement in watershed management tools. Although season and temperature are
rarely considered a factor in hydrographic response of watersheds, field research has indicated that they are factors that
deserve consideration. At the present time, no analytic method by which to simulate these effects has been suggested for field
use. The results presented here provide an indication of the likely effect of temperature on infiltration, abstraction, and runoff
as well as the conceptual tools for including these effects in Corps water-management products. Future research plans include
the development of a method that can be included in hydrologic modeling tools such as HEC-HMS or WMS. This method
will be verified using field observations collected in an urbanized watershed in the Southwest.
