Determining Total Volume of Sediment in Recreational Lakes

 

Xylem has released a new White Paper titled: Determining Total Volume of Sediment in Recreational Lakes.

This latest case study document, written by one of Xylem’s Application Specialists, takes a look at a recreational lake in Brisbane, Australia and details how Xylem employed quality product and specialist expertise to undertake the survey.

I. INTRODUCTION

A survey was performed of a recreational lake within Forest Lake, Brisbane to determine the total volume of sediment deposited in the lake. The survey comprised of the main water body and four inlets discharging into the lake. The survey methods applied during the bathymetry survey varied from bathymetric survey using unmanned surface vehicle and dual frequency echo sounder to topographic survey of the banks and inlets using survey rod and data collector. This technical note gives a broad overview of the equipment and surveying techniques used during the survey process, as well as the methodology followed in developing surface elevation models and calculating total volume of sediment in the lake.

II. SURVEY CONTROL

The equipment chosen for the surveys consisted of two Global Navigation Satellite System (GNSS) receivers, CEE HydroSystems CEESCOPE with dual frequency echo sounder and rQPOD with autonomous navigation. The survey software utilized during the surveys consisted of HYPACK® Hydrographic Survey and Carlson SurvCE software respectively.
