| In 2009, we supplemented our VIC analysis of the Mekong with six other basins. Basin boundaries are the provisional boundaries created from 15-arcsececond DEMs by the HydorSHEDS project. Yes,we see that river deltas are not displayed. They are modeled by other means. |
| As the VIC model involves many vertical layers and timesteps, we must use a spatial resolution that is much coarser than our topographic resolution, though it is still finer than some our input data layers. We have written our own algorithms to consolidate the 3-arcsecond flow directions to coarser resolution. Here are the basins as represented by 5-arc-minute cells. Note that some of the undrained basins are represented at this scale. |
| These are the basins represented as 15-minute grid cells. |
| MODIS 2003 (MOD12Q1 Land Cover Product - MODIS/Terra Land Cover 96 Day L3 Global 1 km ISIN Grid - IGBP land cover classification) tiles were acquired and mosaiced for the region. MODIS supervised IGBP classification are shown on this image. |
| Some of the land cover classifications were reclassified to match vegetation classes and their attributes used previously by the UW group for the Mekong VIC model(Costa-Cabral et al. 2008). The reclassified categories are shown on this image. |
| The Mekong VIC model is being run at a 1/4 degree cell size. 1/4 degree cell units of analysis are shown in red compared to the 1km MODIS data. |
| The percentage of different land cover area for every 1/4 degree cell size of analysis
were then extracted in tabular form for use with the VIC model inputs.
