Geohazards in Bangladesh2

Taking My Class to Bangladesh
My undergraduate Sustainable Development course is in Bangladesh for a Spring Break trip to see what they have been learning about. We will be touring the country by bus and boat to learn about the environment and people of Bangladesh.

Sylhet City, Geology, and Packing Up
We finished our electromagnetic survey and mini-field school in northern Sylhet, Bangladesh, with lectures and field trips to see the geology by car and boat.
-
Start of the Mini-Field School
We were joined in our electromagnetic investigation of the subsurface and earthquake hazard by a group of US and Bangladeshi students and professors for a mini-Field School.
-
Tea Gardens to the Rescue
We switched to deploying our equipment for imaging faults and the structure beneath the surface to tea gardens to get away from power lines and buried the cables to protect them from gnawing foxes.
-
Dealing With Rain and Rats
As we continued our geophysical measurements, we had to deal with heavy rains, flooding fields, and rats and foxes biting our cables. Many cables were broken soon after sunset, ruining the measurements.

Fieldwork in Bangladesh During the End of Ramadan and Eid Festival
We have come to in Bangladesh in the pre-monsoon heat to better image the active faults beneath the surface using electromagnetic instruments. We are using the fallow fields from the just-harvested rice crop for our sites.

Struggling With Towed Equipment, Repairing GPS, and Home
We switched to a towed electromagnetic system to image the fresh and saline groundwater in Bangladesh, and ran into a variety of problems, including high winds, strong currents and running aground.
-
Continuing the Survey: Watermelon and Winds
Continuing our electromagnetic survey of fresh and saline groundwater, we saw the landscape change from lush watermelon fields to fallow rice fields as the salinity increased towards the sea.
-
Barisal and the Eastern Channel
We are continuing our measurements of fresh and saline groundwater in Bangladesh using electromagnetic instruments. We finished our first set of measurements and have now shifted farther east near Barisal where groundwater is fresher.
