Paper short abstract:

The data obtained by Inrap survey around Siem Reap Airport provide accurate informations about soil microtopography and corresponding sediment movements. They were gathered and exploited using GIS, which helps 3d modelling of each stratigraphic unit, that can be considered according to human impact.

Paper long abstract:

The archaeological evaluations made by Inrap around the Siem Reap International Airport totaled fifty hectares, who were surveyed since 2004, through stratigraphic exploration trenches, up to about 5% of this surface. On zones 1 to 6, or 23.4 acres southeast of the tracks, they have recorded 286 representative logs of the soil cover. On an average thickness of 2 m, sedimentary sequences were stored in a georeferenced database (GIS), lending to extrapolation of a topographic modeling, for each identified stratigraphic unit. The data obtained provide accurate informations about soil microtopography and corresponding sediment movements. These reliefs give an inventory of soils according to their degree of human impact and their deposition context. This approach calls for standardization of soil descriptions collected by different international teams involved in this area.
