Ground Water and Surface Water in the Haiku Area, East Maui, Hawaii

摘要

The purpose of this report is to describe (1) the regional relation between211u001esurface water and ground water, (2) the conceptual model of ground-water 211u001eoccurrence, and (3) flow characteristics of individual streams in the Haiku area 211u001eof northeastern Maui. Existing streamflow data were analyzed to estimate 211u001egroundwater discharge into streams. Streamflow measurements were made along 211u001eselected streams in the study area to characterize the gains and losses along the 211u001estream length. Water-level maps were produced on the basis of water-level 211u001einformation contained in the drilling records of wells in the area. A two-211u001edimensional, variably saturated numerical ground-water flow model was constructed 211u001eto evaluate whether the observed geologic and hydrologic conditions could support 211u001ea multi-layered variably saturated flow system.
