Here’s a press release from American Rivers regarding some recent dam removals.

Major Week for Dam Removals.

My old firm, Milone and MacBroom was heavily involved with the preliminary design of the Penobscot  restoration project, so the recent funding should help nail down the final design.

This article came out in February 09, nevertheless, I thought it a good article relevant to restoration.

It’s not clear to me why watching a bank erode would be a tragedy.  Presumably the eroded material from the bank would be carried downstream and deposited elsewhere, most likely on a point bar.

One sentence that caught my eye was “Developed by Colorado consultant Dave Rosgen, … the method is not universally accepted.”  It’s not clear to me that Rosgen was the designer personally, or whether his technique was employed.  It’s also not exactly clear what method was used.

For form based alluvial rivers, there are several analog design tools including: component copy, historic replica, geomorphic references, laboratory models, and Rosgen’s classification system.  Depending on the project goals and available funds, any one of these tools can guide a restoration project, many times successfully.

I found the sediment loading reduction numbers fascinating.  A 200+ million ton/yr reduction in sediment loading is rather significant, to put it mildly.  I think this number is critical to keep in mind in light of any future restoration project.

As to the sea level rise forecasted estimate, only time will tell.

Here’s  a link to a cool page. Much of this work was funded through the National Science Foundation.  I have to admit that I found the sediment transport videos the most enjoyable.

USGS New GeoPDF maps

As part of The National Map project, the USGS is releasing a new format for digital maps.

Digital Map – Beta.

It looks as though nationwide coverage will not be available for a few years.

This is a cool web based tool to view mean daily flow data from USGS gages.  Plug in a station #, variable (00060 is the code for discharge) and a start and end date.  Wait for the data to come in, and then click through the tabs. Very slick!


For those in Cache Valley, Utah, the Little Bear River web service operated by Utah State can be viewed using this customized time series analyst here:
