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.

Principal Investigator

Human Resource Requirements - 2 to 3 man-years/year

Collaborators

Wayne OÕNeal, Jeff Powell, Broderick Davis.
