Cím:	Testing different field survey methods for lateral erosion monitoring at the tributaries of the Lower Mississippi River / László Bertalan, Kory M. Konsoer
Dátum:	2017
Megjegyzések:	The meandering behavior in alluvial rivers is a complex process influ-enced by several geomorphological, hydrological and climatic factors i.e. flood recurrence intervals, flow regime, effective discharge, spatial and tem-poral trends of precipitation, bank material, riparian vegetation, etc. However, the overall channel planform dynamics can be calculated based on cartograph-ic data or aerial imagery but these processes could result an extreme rate of land degradation by the intensive lateral bank erosion process; thus, detailed field surveys should be carried out for the better understanding of the driving factors. River channel bathymetry is a significant element that affects the lateral bank stability. High resolution channel topographic data were collected using Multibeam echo sounder (MBES) that collects bathymetric soundings in a swath perpendicular to the ship track by electronically forming a series of transmit and receive beams in the transducer hardware which measure the depth to the riverbank. Three-dimensional flow velocity measurements were performed along cross sections oriented perpendicular to the channel center-line using a boat-mounted acoustic Doppler current profiler (ADCP). To compare the near-bank velocity fields to bank morphology and roughness elements, detailed topographic data of the outer banks were obtained using a Terrestrial Laser Scanner (TLS). Our test campaigns were carried out at the Amite, Comite and Pearl Rivers as tributaries of the Lower Mississippi River watershed. This poster gives a brief summary of the conditions of these kind of novel field survey methods for fluvial geomorphology.
