Sub-areas of the LMB for the Basin Development Plan
No.184, Unit 18, Fa Ngoum Rd., Ban Sithane Neua
The result of SWAT models was modified by dividing catchments along the Mekong mainstream into left and right bank, using the centre line of the river prepared by Penroong, TSD. The resulting coverage were grouped into major sub-areas (1-11) according to the defining criteria to form BDP_SA10. An area of 695 km2 around Muang Sing in Luangnamtha in Northern Lao PDR is omitted from the SWAT basins for the LMB in the WUP models, as it drains northwards into China. However, this area has been included in BDP SA1, since it drains into the Nanla Ho, which eventually drains back into the Mekong north of the border between Lao PDR and China. Two of the SWAT basins in the north (101 and 206) fall mainly in China and Burma. These were subdivided along national boundaries, and the appropriate proportions assigned to the relevant BDP sub-area. For planning purposes, only the areas within the LMB countries are considered, though the hydrological inputs from transboundary areas are taken into account. It should be noted that the LMB boundary as defined for the WUP models using SWAT differed slightly from the standard LMB boundary used by MRC (as depicted in the TSD dataset b_lmbbnd50. The two main areas of difference are in the north of the basin (where a much larger area in Myanmar and China is included in the Lower Basin); and in the south-east, which includes areas in Svay Rieng, Long An and Tay Ninh outside the nominal dry season LMB, but affected by Mekong flooding. The boundary differs slightly in other areas as well - notably that an area of northern Luangnamtha which drains north into China is omitted from the LMB as defined for the models; and there are discrepancies along the boundaries, particularly in the Central Highlands. BDP sub-areas are defined on the basis of hydrological units, and are designed to facilitate analysis of hydrological outcomes from the WUP models. For convenience in working with the models, the BDP sub-areas have been defined using the LMB boundary from the WUP models. The discrepancies are not generally large, and are NOT SIGNIFICANT at the level of regional analysis.
