				Laos: Field surveys 1995, 1996 and 2000

				STATUS :  
				Last update: May 2003
				Completion status: 100 %
				
				COMMENTS : 
				Cambodia and Vietnam  -  Derived from the max water levels derived for the year 2000 flood by the hydraulic model.
In the southern part of the Vietnam flood area towards the coast it is difficult to differentiate between ‘real flooding’ and temporary inundation from ‘rainfall’ or ‘tidal flooding’.  A fairly well defined boundary to the flood extent has been defined from surveys by the Vietnamese counterpart office combined with Radarsat images. Areas of inundation from the model outside this previously defined flood extent have been clipped and considered as not flooded.
The area around Phnom Penh is protected by flood dykes so the output of the model for this part has been corrected by clipping.
Areas of local flooding (mainly from tributary rivers) not covered by the model but identified by the radarsat have been added to the flood area
				
				FIELD ATTRIBUTES:
				INUNDATE  	inundation area
				20 - Flooded
				0 - Island (not flooded)
				
				UPDATES AND CHANGES:
				Paul Gager May 2003 - This file is an update of the version produced by the LRIAD project. The major differences are:
				The MIKE11 model has been used in place of the VRSAP model in Cambodia.  The 2002 Radarsat has been used in Thailand, since the earlier data was not well registered.  More details are available in the NGIS report "Improvement of MRCS Regional Flood maps, 2003".
