To enhance the efficiency of sounding in rivers, we have developed and assessed a new water depth estimation method using digital elevation model obtained by laser profiler and RGB value of digital aireal photograph.
In this field study, average discrepancy between actual measurement and estimation with the new method was about 0.43m. The new method is able to estimate river bed elevation and cross section form schematically.
