Arroyo sediments often have much higher infiltration rates than soils of the surrounding land surface. As runoff flows through an arroyo, a portion of the stormwater infiltrates into the alluvial sediments. Those so called transmission losses can have a significant impact on peak discharge and total runoff volume, particularly during frequent, low intensity storm events. In a recent study, SSCAFCA quantified transmission losses in the Montoyas Arroyo in Sandoval County, New Mexico.
The findings were published in the ASCE Journal of Hydrologic Engineering:
