Volcanic aquifers of Hawai‘i—Hydrogeology, water budgets, and conceptual models

Abstract

Table of Contents Abstract Introduction Study Area Hydrogeologic Framework of the Islands Fresh Groundwater-Flow Budget Conceptual Models of Groundwater Occurrence and Movement Study Limitations Summary References Cited Appendix 1. Calculation of Groundwater Recharge Appendix 2. Annual Groundwater Recharge, 2001–2010 Revision: Revision to Groundwater Recharge for the Islands of Oʻahu, Maui, and Kauaʻi MAY 16, 2017 An error was detected that affected published groundwater recharge estimates for Oʻahu, Maui, and Kauaʻi (see citations below). Recharge estimates for 1978 2007 rainfall and 2010 land use conditions have been revised and are shown in tables 1 3. Recharge for other conditions and associated reports and datasets will require additional time to revise and publish.
