Course Aim: To impart knowledge on hazards, hazard management and mitigation with special reference to landslides, earthquakes, ground subsidence, saltwater intrusion and soil contamination.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢            apply principles of hazard management to mitigate geohazards.

➢            explain probable landslide hazard at a given location and recommend appropriate measures to mitigate the same.

➢            recognize seismic hazard with particular reference to Sri Lanka and recommend appropriate geotechnical parameters for earthquake resistant design.

➢            solve problems related to ground subsidence, saltwater intrusion and soil contamination.

Course Content:

➢             Hazard management: Hazards, control/prevention, mitigation

➢             Landslides: Types, causes, remedial actions, mitigation, instrumentation

➢             Earthquakes: Occurrence, impact, analysis and mitigation

➢             Ground subsidence: Sinkholes, dewatering, saltwater intrusion

➢             Soil contamination: Potential contaminants, remedial measures

Teaching /Learning Methods:
