Native Hawaiian communities hold wai (fresh water) and its life-giving power as sacred. Wai has been historically managed by Native Hawaiian communities to sustain food security on the most remote islands on Earth. However, in the past century, land use and socio-economic change has transformed many of Hawai'i's coastal landscapes, leading to altered groundwater recharge, storage, and transport, and reduced surface water flows. These changes have contributed to the decline of traditional agroecology and aquaculture systems at He'eia National Estuarine Research Reserve (NERR) on O'ahu, Hawai'i. To bring back abundance into the He'eia ahupua'a (Native Hawaiian social-ecological land and sea division roughly following watershed boundaries), the community expressed the need to understand how much and what kind of wai flows through the wetland and estuary, and its potential influence on the restoration of Indigenous biocultural systems. This project performed an in-depth characterization of surface and groundwater flow throughout He'eia to inform biocultural restoration and future groundwater management. Building on previous conceptual understandings, the project team measured surface and groundwater flow within He'eia. This project elucidated main questions characterizing the quantity, quality, and ages of surface and groundwater flowing through the He'eia watershed, with downstream implications for food and wildlife, fishpond productivity, and nearshore reef health. Looking forward, this work established collaborations with Indigenous resource managers, interfaced with complimentary work conducted by utility and government agencies, and provided 'ike to inform comprehensive and collaborative management of wai in the He'eia ahupua'a. The project's collaborative process was essential to this work and included the convenings of a project advisory group and intended users (named Hui WAI). Iterative Hui WAI meetings shaped the project from its beginning to end, through the codevelopment of the proposal, research methods, workshops, and outputs. This process enhanced communication and relationships among investigators, resource managers, educators and helped build collective knowledge of the ways wai links biocultural restoration projects at partner sites. Major outputs from this work include: 1) a dataset describing above and belowground hydrology and water quality in He'eia, including seasonal and extreme event variability; 2) a consolidated web-based access point to multiple data streams related to water quality and hydrology in He'eia; 3) workshops that promoted intergenerational transfer of 'ike (knowledge) of water management, with shared objectives of Indigenous and conventional knowledge on cultural, scientific, policy, and management aspects of water; 4) piloted water science and management education programs at partner sites; and 5) data analysis reports and conference presentations shared with local, national, and international audiences advancing the knowledge of hydrology and nutrients as they relate to biocultural restoration. The Impact Enhanced communication and relationships among investigators, resource managers, educators, and users which has inspired future reciprocal and collaborative efforts at the watershed-scale. Researchers and partners attained a more nuanced understanding of hydrology and nutrient dynamics in He'eia watershed, and will apply this understanding to policy decisions, agro-ecosystem and Indigenous aquaculture restoration planning, and habitat conservation. Improved access to up-to-date data from multiple sources, allowing resource managers to better adjust management practices on daily to monthly scales. Better understanding of cultural values surrounding wai, local hydrology, relevant water policies through the workshops and implementation of education curricula. Tiered mentoring helped develop the skills and confidence of water scholars at stages in their career and education. completed Office for Coastal Management 2234 South Hobson Avenue Charleston SC 29405-2413 https://www.coast.noaa.gov/ WWW:LINK-1.0-http--link Office for Coastal Management Website Website listed for Office for Coastal Management information custodian asNeeded EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC CHEMISTRY > NOBLE GAS > ATMOSPHERIC RADON > RADON SURFACE EARTH SCIENCE > OCEANS > SALINITY/DENSITY EARTH SCIENCE > OCEANS > WATER QUALITY EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > GROUND WATER > GROUND WATER PROCESSES/MEASUREMENTS > DISCHARGE EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > ISOTOPES > STABLE ISOTOPES EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > WATER QUALITY/WATER CHEMISTRY > NUTRIENTS theme Global Change Master Directory (GCMD) Science Keywords 17.0 Indigenous aquaculture system Submarine groundwater discharge Surface water groundwater interactions age tracers apparent age loko i'a, fishpond nutrients radon recharge source tracking salinity spatial measurement stable isotopes of water stream discharge time series measurement water flow water quality monitoring theme He'eia NERR, HI place DOC/NOAA/NOS/OCM > Office of Coastal Management, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
