Tung Dao's sediment bamboo fences
About the project
Promotors/ supervisors: Prof. dr. ir. M.J.F. (Marcel) Stive, Dr. ir. B. (Bas) Hofland
The mangrove forests in Southern Vietnam have been facing vast destruction over the past decade due to severe erosion along the Mekong Delta coast. To recover the loss of mangroves, wooden fences (as supportive structures) can be built to reduce the incoming wave energy in front of the mangrove belt. Thereby, more sediments and nutrients become available in the downstream basin for mangroves to grow. The design consists of two vertical bamboo poles as a frame to support the horizontal bamboo and tree branches (brushwood) which together form a fence. This fence forms a mechanism for wave reduction.
To research the role of the wooden fences in the mangrove restoration process, Tung researches the hydraulic processes by carrying out flow resistance experiments, and using both a physical and numerical model. The experiments to determine the friction coefficient for flow resistance were carried out in the hydraulic laboratory of TU Delft. The wave-fence interaction is also analyzed in this lab using the wave flume. The data is used to validate the numerical model (SWASH, developed by TU Delft) in order to carry out further wave-fence simulation in the field.

About Tung Dao
Tung Dao was born in Hanoi, Vietnam. After high school graduation in 2006, he started to study coastal engineering at Thuyloi University. In 2011, he graduated and continued with the master program of coastal engineering, also at Thuyloi University. In 2014, he became a lecturer at Hanoi University of Natural Resources and Environment (HUNRE). He received a scholarship from the Vietnam International Education Department Fellowships project in 2016 to study at Delft University of Technology in the Netherlands. Besides coastal engineering, Tung Dao is interested in marine biology and water management. In his spare time he enjoys table tennis and photography.
