Abstract
Recent integration of bathymetric underwater surveying technology with mobile
laser scanning from the same vessel platform allows engineers, operators and
maintenance personnel in several disciplines the opportunity to inspect water
retention features (such as dams and levees) in a virtual desktop environment.
The nature of the data collected along the watercourse characterizes the river
both above and below the waterline at any location. Additionally, it allows
consideration of the impact of objects affecting river flow during hydraulic
modelling as well as evaluation of changes in the river caused by sediment
dynamics. The product is a comprehensive data set that extends from the
riverbed, through the riparian zone and into the floodplain and captures features
with an unprecedented degree of resolution and detail. Consequentially, virtual
inspection and assessment of assets and features as well as improved detail and
accuracy in hydraulic modelling become possible. The result is a major
improvement in the ability of an individual to perform an evaluation of the
watercourse.
Keywords: surveying, bathymetry, LiDAR, laser scanning, virtual inspection

1 Introduction
Water retention infrastructure plays a vital role in protecting communities from
the dangers of flood hazards and in many cases provides sources for
hydroelectricity. Episodic events that jeopardize this infrastructure as well as
virtual inspection of water retention
