Abstract
from all the previous results, we could confirm that different remote sensing
and GIS techniques coupled with field and laboratory investigations provide
great help in the geological hazards assessment. The most advantages of
remote sensing are 1) it cover a wide spectrum of resolution (low to very high),
2) it gives us the ability to cover very large areas, 3) less cost and 4) saving
time
For Karst hazards
We can extract the following points regarding the karst hazards:
An extensive field investigation was used to determine and classify
different types of karst features in the study area.
The integration of satellite remote sensing with the field data proved to
be a successful method in identifying karst features.
The high-resolution remote sensing data were found very helpful in
mapping different karsts deposits and features.
Developing a systematic data collection and analysis to establish a
database management system using geographic information systems
would be highly desirable to determine, assess, and manage different
types of karst and/or sinkhole hazards.
Application of geophysical techniques to the planning areas, especially
those that will be established above karstic rock units, will be beneficial
tools to understand the subsurface karst features.
For landslide hazards
In this part, the following aspects were extracted regarding the landslide
hazards:
In the current study application of high-resolution, 3-D images and the
sketching method were very helpful in determining slope instability
related features and prepare slope instability maps.
