    dct:description "Water-surface elevation measurements were collected in Spring, 2015 along the upper Willamette River, Oregon, between Harrisburg and Corvallis. These surveys were collected over a small range of discharges, from 6,900 cubic feet per second to 8,300 cubic feet per second, using a real-time kinematic global positioning system (RTK-GPS) on a motorboat at various cross sections along the river. These datasets were collected for equipment calibration and validation for the National Aeronautics and Space Administration’s (NASA) Surface Water and Ocean Topography (SWOT) satellite mission. This is one of multiple survey datasets that will be released for this effort." ;
