Project Objective |
The objective is to demonstrate the utility of using echo sounding, side scan sonar and subbottom profiling techniques to characterize foundation materials in fluvial and lacustrine environments and to assess the potential for stream scour in fluvial environments. Echo sounders provide highly accurate estimates of water depths; side scan sonar provides 3-D acoustic images of the river/lake bottoms; subbottom profilers provide extremely high-resolution 2-D images of the sediment/rock to depths on the order of 60 meters. . | ||||
Project Abstract |
The determination of water depths and soil/rock conditions in lacustrine and fluvial environments is critically important in terms of assessing the potential for scour and characterizing water bottom foundation conditions (including soil thicknesses/lithology and rock conditions), especially in karst terrain. The objective is to demonstrate the utility of using echo sounding, side scan sonar and subbottom profiling techniques to assess water bottom foundation materials in fluvial and lacustrine environments and the potential for stream scour in fluvial environments. Echo sounders provide highly accurate estimates of water depths; side scan sonar provides 3-D acoustic images of the river/lake bottoms; subbottom profilers provide extremely high-resolution 2-D images of the sediment/rock to depths on the order of 60 meters. Data will be acquired in proximity to existing bridges with the intent of mapping water depths, preexisting scour features, and top of rock. Data will be also acquired over time to demonstrate how water depths vary seasonally and in response to variations in flow volume. |
