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 Water Quality--current conditions
Suspended-sediment concentrations are determined from samples collected by an autosampler or collected manually.
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.
