Low Head Dam Removals

Attended an excellent workshop on the removal of low head dams.  Their impacts can be far-reaching and include public recreational use, stream ecology, water resources, the transport of sediment and bound contaminants and others. It is key to understand the complexities of each dam and its unique local environment.


Awesome! 2013 IGS calendar features LiDAR dataset of East Fork of the White River

The folks at the Indiana Geological Survey are always pushing forward. This year's calendar shows the relict and modern-day stream channels of the East Fork of the White River just south of the confluence of the Driftwood and Flatwood Rivers near Columbus, Indiana. Cartographers at the Indiana Geological Survey analyzed elevation data using geographic information system software, or GIS, to create the image. The data were acquired using an airborne laser with a technology called LiDAR—light detection and ranging. At the Indiana Geological Survey, LiDAR elevation and corresponding intensity data are a crucial component of our geologic mapping efforts.

Techniques to Quantify Stream-Groundwater Exchange and Shallow Transport A Hands-on Workshop

Looking forward to participating in the upcoming workshop for hands-on experience with novel techniques that can be used to investigate stream-groundwater interactions. Participants will learn to apply four novel techniques and learn related experimental design, data acquisition, data processing, and analysis issues for stream-groundwater interaction studies. http://www.cuahsi.org/stream-gw-wkshp.html
