ABSTRACT:
The problem of groundwater management has been studied widely in the literature. However, all of the previous studies limited their attention to the single aquifer case. In many places, water can be extracted from more than one source to supply the demand. For example, the Honolulu Board of Water Supply (HBWS) currently extracts from both the Pearl Harbor and Honolulu aquifers, pumping the resource into an interconnected pipeline serving the Pearl Harbor and Honolulu water districts. HBWS imports water extracted from the Pearl Harbor aquifer to meet Honolulu demand. This called for a single model integrating extraction, distribution, and consumption from the two sources. This model provided an analysis of a situation much closer to that actually observed in HBWS practices. Particularly, we analyzed the principle of optimal water use when water can be extracted from two sources. We also discussed various possible extraction schemes.
