Abstract

Several Hawaiian streams show downward trends in stream flow. In this study Makaha Stream is investigated as an example. Three possible reasons are commonly mentioned for the discharge reduction: groundwater pumping, decreasing rainfall, and changes in vegetation. The effect of these factors on stream flow is evaluated with the model DHSVM. It appears that groundwater pumping is the most likely reason for stream flow reduction in Makaha Valley. To improve the model results more information about the complex volcanic underground is required.
