Geohazard Management - CE515

Credits : 2

Prerequisites : -

Compulsory/Optional : Optional

To impart knowledge on hazards, hazard management and mitigation with special reference to landslides, earthquakes, ground subsidence and salt water intrusion.
Intended Learning Outcomes
On successful completion of the course, the students should be able to;

  1. Describe principles of hazard management and apply them to find ways to mitigate geohazards.
  2. Identify landslide hazard and propose structural and non-structural measures to mitigate the same.
  3. Describe the seismic hazard with particular reference to Sri Lanka and determine necessary parameters for earthquake resistant design.
  4. Identify and propose solutions to problems of ground subsidence, salt water intrusion and man-made hazards.
Course content/Course description
  1. Hazard management (hazards, control/prevention, mitigation)
  2. Landslides (types, causes, remedial actions, mitigation, instrumentation)
  3. Earthquakes (occurrence, impact, analysis and mitigation)
  4. Ground subsidence (sinkholes, dewatering), salt water intrusion
  5. Manmade hazards (vibrations, contaminants)
