The drillers insert the larger diameter 4" PVC pipe into the well.  Handling the 10 meter pipe is challenging.

Last Sample and Home

We finished our work at the river transect. Now we had one more sample to collect. Alamgir had arranged for drillers at this new site, but they were delayed because of a knife fight between two villages over some property.

Hammering the OSL sampler, which is at the end of many auger extension rods.  The sampler fits inside the 3" PVC pipe that had been installed.

OSL Samples at Last

The success of the tube wells for drilling and obtaining samples was a great boon to our field program. We drilled three additional tube wells to complete a five-well transect across the abandoned river valley. When we date the samples, we will find out if the river switched position suddenly, possibly from an earthquake.

Standing ankle deep in mud by the resistivity meter.  The smokestack of the brick factory can be seen in the distance.

Tubewells to the Rescue

The resistivity testing was hampered by bad roads and flooded fields. The augering was proving similarly difficult in the thick muds of the abandoned channel. It was time to change to our alternative plan: drilling with tube wells. That worked better and we had turned a corner.

The Taj Mahal. You can see its enormous size from the line of people waiting to get inside standing on the pedestal. The line completely circled the tomb on this holiday weekend.

Bangladesh and India, Too

Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very successful.

Help for Indian Small Farmers in a Changing Climate

While a much-needed insurance reform is a welcome change in the Indian agricultural sector, enabling smallholders to be self-sufficient in the wake of climate change and India’s alarming problem of groundwater depletion would be an added plus.

The liberal use of water for irrigation by farmers cultivating rice is contributing to a rapid drop in groundwater levels In the northern Indian state of Haryana.

Overuse of Water by Indian Farmers Threatens Supply

Convincing farmers that it’s worth it to reduce their water consumption will rest on our ability to help develop local groups to manage aquifers at the community-level.
