Advancements in In-Situ Flume Investigations for Sediment Dynamics and Particle Tracking

This report by Hans Biberhofer details the latest advancements in sediment investigations using in-situ flumes. A new velocimeter has been installed to enhance the capabilities of the test chamber, allowing for the capture of mobilized particle segments. The integration of additional sensors, including OBS and LISST, is planned to further improve data collection. Various surveys, including STING and GeoTech, have been conducted across multiple sites, with significant findings on impacts in Little Lake George and surrounding areas. Future enhancements will focus on bathymetric measurements and plume dispersion studies.
