Chad Reese and Chuck Parrett of the Wyoming-Montana Water Science Center measure channel width for a small stream near Helena, Montana. Streams of this size are often measured using an instrument called a flume designed to constrain all flow to an artificial channel with a known mathematical relationship between water level and streamflow.

Katherine Chase, USGS Hydrologist, has more than 30 years of experience in water resources, including hydrologic and hydraulic modeling, floodplain delineation, statistical analyses, and hydraulic structure design and evaluation. Her research with the USGS has included precipitation-runoff modeling, 1-dimensional and 2-dimensional surface-water hydraulics, streamflow statistics, floodplain delineation, channel morphology, and bridge scour. As a consultant she worked on multi-disciplinary teams as a hydrologist/civil engineer, performing wetlands and floodplain delineation, flood mitigation, bridge scour evaluation, and hydraulic structure design. As a graduate research assistant for the National Park Service, she worked on hydrologic and hydraulic modeling and surveying in support of water rights negotiations. Her Peace Corps work in Nepal included surveying, design and construction of irrigation systems, drinking water supply systems, and flood mitigation. She is a licensed Professional Engineer in Montana and Colorado.
