Current Research Interests

  1. Construction of 3-D geologic model of Hanoi City, Vietnam
  2. Spatial distribution of land subsidence in Hanoi City, Vietnam, using GIS and RS

Example of visualization of 3-D topographic map in Hanoi City, Vietnam, using GRASS GIS

Hanoi City is located in a flood plain of the Red River, the average elevation being less than 10 meters. In this city, where people depend on the groundwater to sustain life, the recent rapid increase of population is increasing demand of groundwater as well. This has caused a remarkable and serious land subsidence over the whole urban area. To comprehend what happens around a serious land subsidence area, it is necessary to understand the distribution of groundwater in the subsurface structure. Because 3-D geologic modeling is useful for solving this kind of problem, I will introduce this technique into area studies and propose to establish this method as a special analysis using area informatics. The linked research between the subsurface information and aboveground information will become a new type of knowledge in area studies.
