important structures. Regulations may also involve relocating people or infrastructure away from hazardous
areas, particularly if alternative sites exist. Restrictions can be placed on the type and number of buildings that
can be erected in high-risk areas. Similarly, activities that might activate a landslide can be restricted to take
place away from avalanche prone areas. Restrictions can be implemented through measures such as policy
and building codes.
Early warning systems
Session 14
An early warning system can be an effective measure to mitigate the impacts of LDOFs, particularly in saving
lives and property. Depending on the situation, a variety of systems can be implemented. In many cases,
the best option is to implement a community-based early warning system. This may consist of people placed
at strategic locations from the dam site to the greatest distance downstream where an LDOF could have an
impact. Each person should have visual contact with the person just upstream and downstream. An early
warning system is part of a monitoring, warning, and response system (MWRS).
