Seepage-run discharge measurements on the islands of O'ahu, Moloka'i, Maui, and Hawai'i, 2018 to 2022

Metadata Updated: October 29, 2023

This data release is part of a cooperative study to assess streamflow availability under low-flow conditions for streams on the islands of O'ahu, Moloka'i, Maui, and Hawai'i from 2018 to 2022. This data release contains 24 child items that consist of the following files: (1) a metadata xml file describing the data release files and data attributes, (2) an annotated NWIS-Mapper screen-captured image showing the seepage-run measurement sites, and (3) a comma-delimited ascii data file with the discrete discharge measurements. These discrete discharge measurements form what is commonly referred to as a “seepage run.” The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging flow conditions (or, in some cases, were made simultaneously during transient flow conditions) and external surface inflows (for example, a tributary) or outflows (for example, a diversion) of water to the reach are quantified and accounted for in the computation of net seepage.
