Low-flow characteristics for streams on the Islands of Kauaʻi, Oʻahu, Molokaʻi, Maui, and Hawaiʻi, State of Hawaiʻi

Abstract: Statistical models were developed to estimate natural streamflow under low-flow conditions for streams with existing streamflow data at measurement sites on the Islands of Kaua'i, O'ahu, Moloka'i, Maui, and Hawai'i. Streamflow statistics used to describe the low-flow characteristics are flow-duration discharges that are equaled or exceeded between 50 and 95 percent of the time during the 30-year base period 1984-2013. Record-augmentation techniques were applied to develop statistical models relating concurrent… Show more

“…This can discharge groundwater onto the land surface, directly into the stream, or into the ocean [7]. Under drought conditions, streamflow in windward O'ahu streams, where flow is dominated by dike impounded groundwater discharge, can decrease to about half the median flow, while flow in perennial streams in leeward O'ahu can decline to between 10 and 25% the stream's median flow [8].…”

“…A majority of these investigations were conducted on a basin scale with a focus on computing low-flow characteristics, examining the effects of surface-water diversions on low flows, and, in some instances, examining habitat availability for native stream fauna (Fontaine, 2003;Gingerich, 2005;Gingerich and Wolff, 2005;Oki and others, 2010;Cheng and Wolff, 2012;Cheng, 2014). Statewide analysis of low flows includes studies by Yamanaga (1972), Fontaine and others (1992), Cheng (2016), Bassiouni and Oki (2013), and Clilverd and others (2019). For many of these studies, accuracy of the discharge estimates could be improved with longer periods of record at active continuous-record stations and additional continuous-record stations in areas with little or no streamflow data, such as Moloka'i and Hawai'i island, and leeward areas of all Hawaiian Islands.…”

“…Seepage-analyses data collection included in the monitoring program are not specific to a data-collection network because results of seepage analyses benefit the goals of both networks. Streams with existing seepage-analysis data as of 2016 are summarized in Cheng (2016, A seepage-analysis data collection is identified for streams in surface-water priority areas and streams in hydrogeologically unique areas (table 16, fig. 11-16).…”

“…These streamflow measurements are summarized in this report. Statewide analysis of low flows includes studies by Yamanaga (1972), Fontaine and others (1992), Bassiouni and Oki (2013), Cheng (2016), and Clilverd and others (2019). The application of record-augmentation methods for estimating low-flow characteristics at sites with either short-term records or partial-records of streamflow data is well documented in many of the aforementioned studies.…”
