Conventional measurements of river flows are costly, time-consuming, and frequently dangerous. This report evaluates the use of a continuous wave microwave radar, a monostatic UHF Doppler radar, a pulsed Doppler microwave radar, and a ground-penetrating radar to measure river flows continuously over long periods and without touching the water with any instruments. The experiments duplicate the flow records from conventional stream gauging stations on the San Joaquin River in California and the Cowlitz River in Washington. The purpose of the experiments was to directly measure the parameters necessary to compute flow: surface velocity (converted to mean velocity) and cross-sectional area, thereby avoiding the uncertainty,...

This dataset contains 10 raw common-offset ground-penetrating radar (GPR) profiles collected at 7 locations in the Edwin B. Forsythe National Wildlife Refuge, Atlantic County and Ocean County, New Jersey, in October and November 2014 and January 2015. A MALA® 80 megahertz (MHz) HDR shielded antenna was used for 3 profiles named DinnerPointAve, GameFarmRd-1, and GameFarmRd-2. A MALA® 100 MHz shielded antenna was used for 7 profiles named ReedyCreek-1, ReedyCreek-2, ScottsLandingRd, SouthWildlifeDr, StaffordAve-eastwest, StaffordAve-westeast, and WescottAve. Pre- and post-processing methods such as filters, topographic corrections, wave velocity determinations, and depth conversions have not been applied to these...
