The hydraulic works on soft soil clay with large horizontal force are easily unstable. For Movable Caisson Dam is a type of lightweight dam, is applied to build in the tidal area so large horizontal force makes it unstable more. The interesting issue is to research the method of stability of structures. Experiments were performed at foundation ditc...

Double-row pile breakwater is one of the vertical-front breakwaters using concrete piles applied in some parts of Mekong Delta. Structure of this breakwater mainly includes two rows of closely spaced piles and a rock core between them, frames are made of double-row pile that connected by reinforced concrete longitudial and transveral beam, rock cor...

Movable dam is one of river barriers that has been studied and applied effectively in the Mekong Delta. The principle of increasing the stability of the dam by enlarging foundation width to reduce the normal pressure so that the dam could be placed directly on soft clay soil without soil improvement. The characteristic of the movable dams is low ve...

To protect the mangrove forests along the coastal areas of Mekong Delta, the research group on coastal and river bank protection of Hydraulic Construction Institute has created perforated hollow pile breakwaters to reduce wave energy. Perforated hollow pile breakwaters (PHPB) were made by vertical perforated piles, they were installed in the ground...

This study proposes a new type of breakwater structure - perforated seawall, which is modified from the traditional quater-circular breakwater. It is installed along the shoreline in order to dissipate the wave energy and protect coastal zone.

The coastal zone of the Mekong Delta is affected by the impacts of global climate change. Intensity and frequency of storm events and floods are expected to increase. Larger parts of the 245 km long shoreline of Ca Mau province are affected by severe erosion. It is thus necessary to adopt appropriate solutions to protect that shoreline. This study...
