Analysis Of Georeferenced Sonar-Based Thalweg And Cross-Sectional River Depth Profile Measurements, Kenneth Wray Swinson
Analysis Of Georeferenced Sonar-Based Thalweg And Cross-Sectional River Depth Profile Measurements, Kenneth Wray Swinson
Masters Theses
Depth is a physical river characteristic that is important for habitat classification, river health analysis, and hydrologic/hydraulic modeling. Recent studies have shown that sonar can be an accurate way of measuring river depth, when compared to traditional techniques, but more study is necessary. The main objective of this research was to evaluate the utility of the CruzPro ATU120S and the Lowrance LMS-350A sonar depth units as tools for collecting river depth measurements along longitudinal (thalweg) and cross-sectional profiles. This included analyzing and evaluating the georeferenced commercially available sonar units for accuracy, precision, and response time under controlled lab and river …
