Fluorescent Emriver Stream Table from Matt Kuchta on Vimeo.

Oh, lets think of all the processes that can be seen in this video.

Sediment transport with spatial and temporal variability, bank erosion, meander cutoff, helical flow, deposition, scour, grain size distribution with differing rates of transport, bed load and saltation, excess critical shear stress, a mobile bed, lateral migration, and inset bars.

What else do you see in this video?

Many thanks for all the hard work that the staff at Little Research and Design do to promote awareness of river processes.

This is a slide show that I’ve been developing on my own for a while. It covers some of the options a modeler has when creating a HEC-RAS steady flow model.

I’m a volunteer for the Ipswich River Watershed Association. (http://ipswichriver.org/) It’s a great organization and it has been working with the NOAA Restoration Center and the MA Department of Environmental Restoration on some dam removal projects. In my town of Ipswich, MA there is a dam in town that is currently undergoing a removal feasibility study.  The budget is tight, which provides a great opportunity for volunteer help.

As such, I created an IRWA GIS group on ArcGIS.com and have managed to make a few preliminary maps that provide some basic information about the watershed and the project site in town. If you are interested contributing to this group, please feel free to click on the ‘join this group’ button.

I also have a Box.net account and have created a shared folder called IRWA. I’m hoping to work with IRWA staff on submitting some USGS gage analyses I’ve done and a hydrology writeup I did that gives some basic background on the flow conditions at the dam.  IRWA has some monitoring programs that involve volunteers collecting field data (dissolved oxygen, temperature, cross sections, macroinvertebrate sampling, and fish counts). Here too, I’m hoping to get these data onto the site so that a broader audience can access and view the data.  Box is currently offering 50Gb of storage for iPhone and iPad users and it has a handy add-in for MS Office applications

Finally, the one site that looks intriguing, but I haven’t really used much yet is AutoDesk’s AutoCAD WS site.  Assuming that an engineering firm is hired to develop some site plans, I might try to push for the plans to be uploaded to this site.  This could cause some concerns for the project partners, but if the people who have access to the site are known, I’m not sure what the downside is.  I’m curious to know if anyone has experience with this site and how it has worked out for them.

In the end, all of these tools get data off of our C: or network drives and allow information to be accessed and edited by a larger group.  I’m excited about the opportunities to work collaboratively with IRWA staff and volunteers using these tools.
