<div dir="ltr"><div>Hello friends!</div><div><br></div><div>Things are not going well here in the U.S. on the environmental front. Among the things I have been working on is grassroots (no pun intended) environmental activism to stop the construction of 2, 42 inch (> 1 m) diameter, high-pressure natural gas pipelines which will be constructed through the Appalachian Mountains (steep slopes, folded, thrust-faulted, seismically active, with lots of Karst geology, etc...) an environmental nightmare.</div><div><br></div><div>The State of Virginia is allowing a final comment period ending June 1 on specified stream-crossing locations by the pipeline, many 1st order stream, totalling about 400 locations. Comments MUST be addressed on a site-by-site basis, dealing with erosion and sedimentation impacts on water quality.</div><div><br></div><div>I need to automate a process (thinking GRASS + R + knitr) to develop individual reports for each location (I have IDs, lat-long values). What I'm asking for are suggestions of what I might include in my analyses that are site-specific, which I could automate through some scripting.</div><div><br></div><div>Since I have each stream-crossing location I could use that as a center for a GRASS region for the analyses. One thought is to try to calculate scour in the stream channels using, among many things, stream gradient; also potentially, erosion based on RUSLE, etc. Most areas are forested (which have been cut down) with agricultural lands.</div><div><br></div><div>Any high-level suggestions??<br></div><div><br></div><div>Best,</div><div>Tom<br></div><div><br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr">Thomas E Adams, III<div>1724 Sage Lane</div><div>Blacksburg, VA 24060</div><div><a href="mailto:tea3rd@gmail.com" target="_blank">tea3rd@gmail.com</a> (personal)</div><div><a href="mailto:tea@terrapredictions.org" target="_blank">tea@terrapredictions.org</a> (work)<br></div><div><br></div><div>1 (513) 739-9512 (cell)</div><div><br></div></div></div></div></div></div>
