Experimental Analysis of Kinematic Network-Based GPS Positioning Technique for River Bathymetric Survey

Abstract

A waterway where topographical surface water is flowing from higher to lower geopotential is called a river and hydraulic characteristics of the flow is closely related to geometric shape in the longitudinal and cross sections. Note that the river shape keeps changing according to topography and flowing water actions. Due to this reason, a study on periodical river bathymetry is necessary for maintenance that reflects a flow characteristic of rivers. In particular, a variation in local river bathymetry caused by large-scale river improvement projects and hydraulic structures could
