Quantifying Evapotranspiration in Stormwater Control Measures - Evapotranspiration (ET) is a widely recognized, yet quantitatively elusive component of the hydrologic budget in stormwater control measures. Field experiments are compared with common estimation methods to predict ET.

Applicability of Stormwater Management Guidelines for Sizing of BMPs - The existence of a first flush and infiltration characteristics in stormwater management impacts the sizing of BMPs.  Field experiments show that a deeper understanding of the mechanisms of storm flows and BMPs can guide BMP sizing.
