Water Environment and Infrastructure

The Royal Irrigation Department had studied the FS, EIA and SEA (Strategy Environmental Assessment) of the Mekong – Loei – Chi - Mun Water Management by Gravity in northeastern region and finished it in July 2012. It can be concluded that the estuary of the Loei River should be improved; dredging the diversion canal, boring the diversion tunnel and constructing the distribution canal for irrigation and flood prevention should be carried out. The water is distributed to most of the agricultural areas in Mekong-Chi-Mun basins; the irrigation area about 30.64 million rai.

The study focused on the development model in phase 1 and sought out the appropriate alternative for development, considering the budget, break-even point, development distribution, problems, urgent need and hydraulic flow of diversion tunnel in phase 1 by using physical model based on the diversion system structure, starting from Mekong River, Loei estuary (improving Loei estuary, dredging diversion canal and drilling diversion tunnel) to the tunnel exit.
