   intro_statements:
   - As a member of the USGS Geomorphology and Sediment Transport Laboratory, Dr.
     Legleiter conducts research on remote sensing of rivers, specifically retreival
     of depth, velocity, and other channel attributes from various types of image
     data.  Current studies focus on estimating tracer dye concentrations on the
     Missouri River and flow depths and velocities on several rivers&n

   personal_statement: Dr. Legleiter joined the USGS Geomorphology and Sediment Transport
     Laboratory in January 2016. Before coming to the Survey,  Legleiter was employed
     as an Associate Professor of Geography at the University of Wyoming.  He earned
     a doctoral degree from the University of California Santa Barbara, graduating
     in 2009.Dr. Legleiter's research focuses on the application of remote sensing
     to rivers, specifically hyperspectral imaging of sand- and gravel-bed channels.
     His interests also encompass fluvial geomorphology and sediment transport as
     he seeks to understand the mechanisms by which the movement of water and sediment
     direct the morphologic evolution of rivers.  For this reason, Legleiter conducts
     studies of channel change, for which remote sensing has proven to be a powerful
     tool. Current work is focused on developing new methods of measuring river discharge
     and estimating tracer dye concentrations via remote sensing.Remote sensing has
     emerged as a powerful tool for characterizing river systems across a broad range
     of scales and with far greater efficiency than conventional field methods.  Dr.
     Legleiter's research at the USGS Geomorphology and Sediment Transport Laboratory
     (GSTL) focuses on developing innovative techniques for inferring various channel
     attributes from remotely sensed data.  For example, previous studies have established
     methods for retrieving information on water depth from hyperspectral images
     and/or bathymetric (green) LiDAR.  In collaboration with colleagues at the GSTL,
     Legleiter is now working to develop innovative approaches for remote sensing
     of river discharge using a combination of depth retrieval from passive optical
     image data and water surface velocity estimation from thermal and optical videography.  Another
     collaborative project with the USGS Ecosystems Mission Area involves estimating
     tracer dye concentrations from passive optical image data to facilitate dispersion
     studies.
