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 of Maui, Hawaii. The field data collection is part of a study to quantify the impacts of high-priority non-native and dominant native plant species on freshwater availability throughout the State of Hawaii (https://archive.usgs.gov/archive/sites/hi.water.usgs.gov/studies/maui_eco/index.html). The overall objective of the study is to provide needed information for (1) assessing species-specific impacts on freshwater availability and (2) reducing uncertainty in regional recharge estimates associated with forested areas. This dataset includes a summary of 226 individual measurements of soil field-saturated hydraulic conductivity, hydrophobicity, and preferential flow collected at four study sites on the island of Maui between September 2017 and August 2018. The dataset also includes a summary of soil particle-size analyses made on a total of 45 soil samples collected from the four sites.
