Summary of soil field-saturated hydraulic conductivity, hydrophobicity, preferential-flow, and particle-size measurements collected at four study sites on the island of Maui, Hawaii, September 2017–August 2018

The U.S. Geological Survey and the University of Hawaii at Manoa, in cooperation with the County of Maui Department of Water Supply and the State of Hawaii Commission on Water Resource Management, initiated a field data collection program to provide information for determining how infiltration rates and soil hydrophobicity are dependent on plant species type within forested areas on the island...

Summary of soil field-saturated hydraulic conductivity, hydrophobicity, and preferential-flow measurements and soil laboratory-testing results collected at three sites on the islands of Maui and Hawaii, Hawaii, July 2016–January 2018

This data release contains soil-properties for one site (Nakula) on the Island of Maui and two sites (Nahuku and Lapahoehoe) on the Island of Hawaii. Maps showing the site locations are included in one of this dataset’s files (Study_sites_summary.pdf). The soil properties were compiled into three files, each formatted with comma-separated values. Field-saturated hydraulic...

Summary of dissolved pesticide concentrations in discrete surface-water samples collected on the islands of Kauaʻi and Oʻahu, Hawaiʻi November 2016–April 2017

This dataset includes pesticide-concentration results for 32 discrete water samples that were collected on the islands of Kauai and Oahu between November 21, 2016 and April 29, 2017. The water samples were collected for the Pesticide-Monitoring Program of Surface Water in the State of Hawaii. This dataset consists of five files: a summary file, a sample-list file, two results files, and this...

Mean annual water-budget components for the Island of Kauai, Hawaii, for predevelopment conditions, 1978-2007 rainfall and 1870 land cover (version 2.0)

The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of predevelopment conditions (1978–2007 rainfall and 1870 land cover), as described in USGS Scientific...
