Dick,

I am sending you the quaterly report as required by the contract.
I would also like to ask about the possibility to continue work on 
this project into next year, especially in relation to the development 
of the LMS. I know that the future contracts depend on the 
IDIQ, but if it goes through, there is a good opportunity to develop 
some really useful methods and tools supporting LMS, 
especially when ESRI is participant in our IDIQ.
Over the summer we will start to work on the software part of the project
which includes some interfaces related to LMS - should I contact 
Alan Anderson to get some specifics for this task? 
(We would need an access or at least a description of the LMS tools 
which will be using the erosion model as its module).

The ISCO conference where both Steve and I have presented our work
funded by CERL was really great - our work was very well recieved and
we have seen many great ideas on how to create healthy landscapes, which
can be useful for military installations.

thank you for your support,

Helena

P.S. Please let me know if you need a more formal report and a hardcopy.

CERL quarterly report

Task 1.
We have computed the DEM for Ft Hood test watershed from IFSARE 
and field data.Both data sets were very noisy and required non-trivial 
effort to get reasonable terrain representation. The original, unprocessed
IFSARE data were much better than the processed integer data.
All data sets for running the erosion models for the demonstration area
at Ft. Hood were created and will be delivered at the end of
the project (or sooner if necessary). We would still
like to recompute everything for the field measured elevation
data if Matt has any success in cleaning them up a little bit.

For the Fort Polk we have computed the DEM and topographic
parameters, however we don't have any soil and landuse map yet.
We will work with Heidi and Chris Rewerts to get the necessary data.
At 5m resolution the DEM for entire Ft. Polk is very big and computation
required substantial compuational resources,
however, the data which we got from Tamie Morgan, MECA Inc., Texas
were very high quality. We are delivering the DEM, slope and aspect
grids through a different project to MECA Inc. and Ft.Polk as GRASS
and ARCGRID raster files.

Task 2. We have processed the Cs data and created maps of Cs gain
and loss, as well as maps of erosion/deposition estimates from our
models. The results are on the www. 
We have developed a cartographic representation of combined terrain,
net erosion/deposition and Cs gain/loss data which allow fast visual
comparison of Cs and erosion/deposition models.

Task 3. Our results as well as the results of several projects 
presented at the ISCO conference show that using Cs data for evaluation
of erosion models is a complex task and more research is needed
in this area. We will use the Cs data for Scheyern farm and
data for an experimental area in England (in cooperation with Dr. Walling's
group), where both Cs and observed erosion/deposition data are available
to further investigate the fate of Cs and its relation to erosion processes.

Task 4. We performed a simulation of a typical event for Ft. Hood
using USLE, USPED and SIMWE. We will do the extreme event after we get
the cleaned data from Matt. We will need some information about 
the rainfall intensities for a typical and extreme event at Ft. Polk
to perform the simulations there.

Task 5. We have started collaboration with the Knox county, Ill
Conservation district and with National sedimentation lab to test 
our models in designing effective grassed waterways and hedges
with focus on preventing gully erosion, which seems to be the most
serious and least studied erosion problem at the installations.
After testing the tools using the detailed experimental data we will 
apply them to our study areas at installations.

Tasks 6. 7. 9. We have USLE and USPED as a simple sequence of
GRASS commands and r.mapcalc calculations. Demonstration and tutorial
will be delivered as a part of the final report. We have performed
computation of USLE within ArcGRID and cooperated with a group
in England to implement USPED in ArcGRID. It was necessary to replace
the standard ArcGrid flowtracing by inhouse program to get adequate
results. To continue work on these tasks we need to collaborate 
with developers of LMS to ensure compatibility of tools.
