SUBJECT:  PROGRAMS AND PLANS--Dendrogeomorphic Techniques

Dendrogeomorphic techniques have provided useful approaches to 
several successful cooperatively-funded projects in the Southeast 
and Northeast Regions.  Dendrogeomorphic techniques refers to the 
use of tree-ring or dendrochronologic investigations in the inter-
pretation of geomorphic form and process.  Sediment deposition, in 
particular, and in many cases erosion are processes especially 
suitable for dendrogeomorphic investigations.

The attached list of salient papers describes the use and 
illustrates potential applications of dendrogeomorphic analysis.  
Substantial information has been obtained using these techniques to 
measure bank-accretion rates, flood-plain deposition, sedimentation 
in wetlands, hill-slope erosion, and debris-flow frequency and 
deposition.  Dendrogeomorphic techniques in wetlands are 
particularly useful, in that no other methodology may provide 
detailed information on spatial and temporal aspects of sediment 
deposition.  The techniques are simple and relatively easy to 
conduct and have been documented in papers listed in the attachment.  
Copies of the publications may be obtained (preferably) from the 
publication outlet indicated in the references, from the author, or 
from the Office of Surface Water.

Currently Hupp's NRP/NR project is involved in studies that 
use dendrogeomorpic analysis in combination with sediment chemistry 
to investigate the transport and storage of nonpoint-source 
pollution.  Tom Yanosky is studying the timing and uptake of trace 
elements in fluvial environments by use of an element analysis of 
wood tissue.  Although element analysis is still in the basic 
research phase, it promises to provide information about sediment 
chemistry, shallow ground-water contamination, and saltwater
