PROJECT TITLE:
Hydrologic Analysis of Hawaii Watersheds for Flood Control and Water Quality Management
PRINCIPAL INVESTIGATOR:Dr. Clark Liu, Water Resources Research Center/Civil Engineering, University of Hawaii at Manoa (UH)
SPONSOR:
USGS State Water Resources Research Institute Program
PROJECT PERIOD:
03/01/06 - 02/28/07 OBJECTIVES:
The principal objective of this research is to develop modeling techniques of hydrologic analysis for Hawaiian watersheds based on the linear systems theory. These modeling techniques, which allow easy interface with GIS, will be tested and applied for flood hydrograph analysis and for the evaluation of non-point sources of pollution, especially for the establishment of maximum total daily load (TMDL).
RESEARCH RESULTS AND FINDINGS:
The multi-regression equations, which correlate the unit response function to watershed properties, were derived. These regression equations were used for the derivation of the unit response function (instantaneous unit hydrographs, IUH) of the Wahiawa watershed on Oahu, Hawaii (USGS gaging station No.16208000). The derived IUH was then applied successfully in predicting the storm runoff generated by a rain storm which occurred on October 24-25, 2005.
