Flood prevention the easy way


Water flows from high areas to low. In the case of a major flood,浪型网, this process can be slow and massively destructive or,cattle fence, according a group of Thai technical experts, it can be quick and relatively painless.



The Thailand Underground and Tunnelling Group has suggested the government invest around 200 billion baht to build a 100km-long tunnel under the eastern section of the outer ring road to prevent future flooding in and around the capital.



Suchatvee Suwansawat, TUTG chairman, yesterday said the proposed tunnel should be built from Bang Pa-in in Ayutthaya to Samut Prakan province where the water would empty into the Gulf of Thailand. It could be completed in two years.



The tunnel would be designed as a double-deck underground structure, called a multi-service flood tunnel system, and would also be equipped with hydropower generators for power production,black wire mesh, Assoc Prof Suchatvee said.



The upper deck would be used as a road under normal conditions when there were no floods or during minor and moderate flooding.



The lower deck would be used as a flood drain during normal situations.



During major floods,gabions, the upper deck would be closed to traffic and turned into a floodway to help speed up drainage of run-off.



Assoc Prof Suchatvee said a similar system should also be considered for the western part of Bangkok.



Large tunnels would be practical, more effective and thus the best solution to prevent major flooding over the long run.



Prasong Tarachai, former president of the Engineering Institute of Thailand said the underground flood prevention tunnel system should be built from Nakhon Sawan.



He also suggested integrating 20 state agencies involved in the water management system and creating a more accurate water information system.



"City planning should be revised to include floodways," he said.

Military Barriers/Hesco Bastions

Information


The QIAOSHI's Military Barriers or Hesco Bastions is a modern gabion used for flood control and military fortification. It is made of a collapsible wire mesh container and heavy duty fabric liner, and used as a temporary to semi-permanent dike or barrier against blast or small-arms. One of the less heralded life- and labor-saving devices of war, it is used on nearly every United States Military base in Iraq as well as on NATO bases in Afghanistan.


Originally designed for use on beaches and marshes for erosion and flood control, the Hesco Bastion quickly became a popular security device in the 1990s.

Assembly
Assembling the Hesco Bastion entails unfolding it and (if available) using a front end loader to fill it with sand, dirt or gravel. The placement of the barrier is generally very similar to the placement of a sandbag barrier or earth berm except that room must generally be allowed for the equipment used to fill the barrier. The main advantage of Military Barrier, strongly contributing to their popularity with troops and flood fighters,Expanded Metal Meshes, is the quick and easy setup. Previously, people had to fill sandbags,sheep fence, a slow undertaking, with one worker filling about 20 sandbags per hour. Workers using Military Barrier and a front end loader can do ten times the work of those using sandbags.
The Hesco Barrier come in a variety of sizes. Most of the barriers can also be stacked, and they are shipped collapsed in compact sets. Example dimensions of typical configurations are 46" x 36" x 32 (1.4m x 1.1m x 9.8m) to 7 x 5 x 100 (2.1m x 1.5m x 30m).
A new system of Hesco Bastion developed specially for military use is deployed from a container, which is dragged along the line of ground where the barrier is to be formed, unfolding up to several hundred meters of barrier in minutes, ready for filling with soil by a backhoe.

Protection
Filled with sand, 60 centimetres (24 inches) of barrier thickness will stop rifle bullets and shell fragments. It takes 1.5 metres (five feet) of thickness to prevent penetration by a rocket propelled grenade round. Approximately 1.2 metres (four feet) of thickness provides protection against most car bombs.
