Modeling and Simulation of Hill Side Feasibility with GIS

Hill Side development has always been a sensitive issue to a development, especially
when it involves the public. In Malaysia, the problems and solutions to a sustainable
hill side development has been largely discussed over the years while in geotechnical
aspect, it is a never ending discussion.
Engineering investigations is hard to be predicted and carried out especially at hilly
area that is often hard to be reached. Thus, engineering feasibility studies are hard to
be carried out and indirectly, it will certainly minimize its accuracy and most often, it
is very much dependent on the engineers experience in making feasibility decisio-i.
This paper presents an integrated system to improve Hill Side feasibility by
modeling and simulation with GIS, the modeling involves, Land Elevation and Land
gradients plotting for Hill Land identification and Hydrological mapping in Flow
Directions Flow Length and flow accumulation to identify the hydrological effects
on the development.
The transformation techniques of data into GIS base are Modeled and Simulated. A
full and clearer development outlook has been presented. Data from different factors
that affecting development is combined and of course in this project, we are focusing
on few selected parameters mentioned.
Techniques and difficulties of modeling and simulation with a large database are
discussed. A user-friendly interface is developed t) support the planning,
management and decision making in the development.
