Yeah can be temporary or permanent. You build a dyke behind it and plant trees and ground cover through a chain link fence, which should stop any erosion events.

If there's a large concrete wall upstream on your plot, then you also have to beware of eddy currents that could develop and eat away at your land below it. Revetment works are tricky at best, and never cheap. I'd be very careful.jackrossi wrote:@ jacked camry: a part of the land has already a massive concrete wall build for protect the bridge head from flooding yet you are right it is not simple to contain costs and ensuring safety. i can go above the 40k mark but it would not increse the land value to a possible khmer buyer proportionally.
i might let this opportunity pass between the sangkat being not sure about any of my questions, ( we went to ask questions such as: where the river boundaries start? or can i have the permissions to dredge sand fron the river?with a professional translator and the answer were mostly a puzzled face like a gecko on the wall when you just turn the light on and a lot of "maybe..., not sure..., i think so"... ) and the complications in construction makes it a bit too challenging.
i will post some photos a bit later.

Method of planting trees on terrace risers
Compiled by Mr. Zhao Jingyong of the Jr. of Soil and water Conservation, China.
Tree species, which are suitable for planting by inserting them on terrace risers, are used. Strong 1-3 year old seedlings with thickness of 0.5-2.0 cm should be selected and cut into strips of 20-30 cm length. A 3 cm diameter, 60 cm long sharp wood is used to make hole on the terrace risers with a spacing of (0.2m-0.50m) × (0.5m-1.0m). The selected tree stripes are then inserted and the whole is filled back with wet soil.
The terrace riser plantation stabilizes terraces and generates income from trees but is limited by rainfall conditions.
Amorpha fruticosa - a good tree species for soil and water conservation
This species is found in reasons with 1,000 m AMSL. It is widely distributed in northeast China, north China, Guangdong, Yuannan and Guangxi Provinces. It has a well developed root system, is resistant to drought, and requires cold and wet conditions to grow and can survive on saline and infertile soils, seriously eroded gullies in both dry and humid climates. It is of high economic value as it is used for weaving, fodder, fuel wood, manure etc. It retards runoff and conserves soil.
A good species of herb for soil and water conservation
Buffalogourd (Cucurbita foetidissima) is a kind of perennial herb of the gourd family with perennial roots. It can survive 30-40 years. The plant promises high oil bearing herbal fruits from the very first year to the end and tuber crop underground. It is therefore a kind of economic plant with multiple applications, high adaptability, readily cultivated on barren mountains and floodplains, which are otherwise not arable. An annual intensive farming and fallow cycle is used. Bringing the plant to mountainous areas in north
China, which is extremely dry and sparsely vegetated, may be rewarding in conservation of soil and water, while at the same time increasing the income of local people by the sale of herb.
Method of building level strips of land by contour plowing8
8 Compiled by Yui Peicheng and Li Yunsheng, Agriculture Research Institute, Chifeng, Inner Mongolia.
Sloping lands can be changed in level stripes by contour plowing in about 5 year period. The ridges formed by this method in between two strips can be further reinforced by planting bushes, fodder grass or medicinal plants on them. This adds to more economic benefits.
For Inner Mongolia region to develop level strips in the sloping lands below 10° contour plow the lands. On the lower side, the height can increase by 20-24 cm and on the higher side the height can decrease by 20-24 cm. The slope becomes gradual after plowing several times. Experience shows that a 7 m wide belt needs to be contour ploughed 3-4 times. A 10 m level land needs to be ploughed 10 times.

temporary barrier for excluding water from an area that is normally submerged.
there are other definitions but I like this one
In the context of Southeast Asia, a cofferdam is according to the definition provided by Violet above. It's a temporary soil structure placed in a river or around a floodplain area to isolate the location where you wish to construct a permanent structure. So, for example, if you're building a weir (a structure used to regulate flows in a small stream), you build a cofferdam upstream that blocks water from coming into your building site and diverts it around the site to the stream downstream of your construction location. Then you can dig out the foundations, pour your structure's floor and walls, and build something that will then be able to withstand flows. You then destroy the cofferdam and diversion channel and allow water to flow through the weir.
The "chain link fence" that Fred was referring to is a gabion basket. Gabions are wire cages that look similar to chain link fences but which are used to stabilize slopes against water flows. They're filled with rocks, not soil.

It is quite an interesting topic, and one I'm happy to engage in a discussion about if there's interest. But it has nothing to do with protecting a Kampong Cham riverbank from the Mekong River flows.

You mean you poured concrete everywhere you went,plus your are old and 26 years is not a long time ,more like something you fell into I guess. Where you like a builders labour before you came to Asia .
PS . My experience is more than 26 years in land management.

Yes, concrete is quite a useful building material for various works, revetment and otherwise. And 26 years is not a long time to work? Uh, okay. As you may have picked up if you paid much attention, I'm a Civil Engineer by training. Prior to Southeast Asia I worked in North America for several years, mainly hazardous waste management but including numerous design/construction/supervision works.Fred Edwards wrote:Jacked Camry wrote:

So your 26 years of land management experience has taught you that upland erosion and water conservation techniques are appropriate for protection works against major lowland rivers? Just because you've been making fundamental mistakes for 30 years does not qualify you to broadcast your ignorance about things you know nothing about. Land management and engineering are two entirely different things, and I should know as I've done both. Tell me again about your experience in construction works to prevent riverbank erosion. I've done it, have you?

Ok, just to try and get back on topic, lets go on. If, for example, you live on a bank that gets hit with the wrong currents, are you always fucked? I guess you could stick in pilings 60 meters deep but unless there's a larger scheme the force of that river will just destroy anything. How far down till you hit bedrock, or is it better to make something that floats?
