The Soil Water Apportioning Method (SWAM): An approach for long-term, low-cost monitoring of green roof hydrologic performance
文摘

We developed a method to monitor green roof runoff and evapotranspiration, citywide.

The method was validated for three extensive green roof types in New York City.

Accurate values were obtained using only one low-cost soil moisture sensor per site.

SWAM’s cost and labor requirements are lower compared to other monitoring schemes.
