Mean annual water-budget components for the Island of Maui, 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 Maui, 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...

Hawaiʻi Rainfall--current conditions

Continuously recording rainfall sites utilize equipment that automatically record and store the amount of rainfall at specific intervals. Many sites are equipped with telemetry so that information can be electronically transmitted and displayed on the internet in real time.

Hawaiʻi Groundwater--current conditions

At some sites, groundwater levels in wells are manually measured, using steel or electrical tapes or pressure transducers. Other sites utilize electronic equipment to record and store the water levels at specific intervals. Some sites are equipped with telemetry so that information can be electronically transmitted and displayed in real-time on the internet.

Hawaiʻi Streamflow--current conditions

Continuously recording surface-water stations are stations with equipment that automatically record and store data at specific intervals. Many stations are equipped with telemetry so that information can be electronically transmitted and displayed on the internet in real time.
