Development of Spectral Cone Penetrometer for Characterization
of Submerged Reservoir Sediment Quality
By Wayne O'Neal
Pre-Proposal
Issue/Problem
Literally thousands of small to large reservoirs are reaching the ends of
their designed lives, and decisions will be made on decommissioning,
rehabilitation, changed use and operation, or other ways that the
reservoirs will be upgraded, made safe, or otherwise changed. Part of the
planning and decision process will focus on the quantity, quality, and
distribution of sediment that exists in the pool. The presence of toxic
sediments will affect the alternatives developed and selected. Currently,
there is no easy and accurate way to map the quality of sediment spatially
and at depth.
Beneficiaries
All who are responsible for making decisions about decommissioning or
rehabilitation of water resources structures that store sedimenT.
Objectives
A tool for determining the in-situ quality of submerged sediment beneathe
the water/sediment interface is needed. It must be portable, acceptable
for widespread use, inexpensive to operate, etc..
Approach
The USACE Waterways Experiment Station (Jeff Powell, ISD) has developed a
truck-mounted Spectral Cone Penetrometer. This instrument
should be able to be transported to a boat mounted system that can be used
to analyse the bed-sediments of reservoirs both spatially and by depth for
quality.
Funding
FY99 -- $250K for development and testing.
