Geohazards in Bangladesh4

  • Long Days in the Field in Southern Bangladesh

    Long Days in the Field in Southern Bangladesh

    We continued our GPS surveys of monuments to measure land subsidence. While the work general went very well, we faced challenges from obscured or tilted monuments. We also struggled with large traffic delays, particularly at unpredictable ferry crossings.

    Getting to remote sites started to prove challenging, and involved many forms of transportation by land and water.

    Back to Bangladesh: How Fast Is the Delta Sinking?

    I am back in Bangladesh once more to investigate the balance between sea level rise, the sinking of the land, and the filling of the space with sediments.

  • North to Patuakhali and Barisal for the End of Our Fieldwork

    North to Patuakhali and Barisal for the End of Our Fieldwork

    We added a campaign monument to the tide gauge at Khepupara on the way to our last GPS and SET installation site at Patuakhali. We faced challenges such as bad roads and broken bridges, and leeches, but got the work done. The field work was now coming to a close.

  • Khulna to Barishal and Kuakata

    We replaced the GPS at Khulna University, then met some colleagues in Barisal. We continued to Khepupara and the beach at Kuakata for more installations. The beach on the Bay of Bengal is fresh water in the summer due to the enormous water discharge at the Ganges-Brahmaputra Delta.

    Silting rivers and bad roads made it difficult to find a last site. After a successful installation and an upgrade to an existing GPS site, we left the boat for land. We then discovered the local river had washed away some of our equipment.

  • Hiron Point Once More

    Hiron Point Once More

    We sailed to Hiron Point in the Sundarban Mangrove Forest to upgrade old and install new equipment. I have been to this beautiful remote site several times before. After competing the work, we sailed for over a day to reach our next site on a primary school roof.

    From Sonatola to the Sundarbans

    By working a 16-hour day, we managed to get both GPS and SETs completed at our first field site. We then sailed into the Sundarban Mangrove Forest, the world’s largest, to visit an existing site and make measurements.

    I am back in Bangladesh for a new project examining the balance between sea level rise, land subsidence and sedimentation. We will be installing, repairing or upgrading equipment to measure changes to the landscape.
