MODERN TECHNOLOGIES FOR MONITORING LANDSLIDE PUBLISHEDCătălina Bianca Stoian (Amza), Anca Maria Moscovici, Ioan Stoian
The project will provide a technical solution for assessment of environmental parameters needed in landslide risk management using advanced technologies that will allow: acquisition of data concerning the underground water level (sensors installed inside caissons),specific environmental parameters, data regarding relative displacement of fitted terrestrial bench-marks (sensors for relative displacement ) ; transmission of field data through wireless communication to a risk management center; modeling and simulation for natural disasters risk assessment; control and observation of risk factors regarding landslides, based on an advanced decision-support system using GIS technologies and business intelligence; complex analysis of historic data and meteo and seismic forecasts, in order to identify the evolution trend (during given time periods) and foresee the risk of landslide and also to - identify on a map critical areas; automatic reporting about parameters evolution due to increased alarm/emergency quota; interactive facilities for creating alarming strategies (actions, tasks, priorities) and generating emergency plans; automatic alerting via Internet according to an emergency plan; presenting information (text, maps) to action group members both on fixed (PC) and mobile devices (PDA, mobile phone). Natural disasters, also known as hazards, cause huge damages every year, directly affecting the social and economical development and also taking away human lives. Hazard means the probability of a human/environment harmful phenomenon to occur during a certain period of time. Vulnerability indicates the level of damage caused by a certain phenomenon to humans and their assets. Risk means the probability of the humans and of their assets to be harmed by a phenomenon of a certain size. The elements on risk are the population, the properties, communications, economical objectives in an area. The global cost of natural disasters has grown over 800% in the last four decades being connected to an increasing vulnerability of the population living in high risk areas. Landslides are disasters that destroy villages and towns, damage roads, railways, farm fields and have negative effects on every person that lives in the affected area and generally on society. The causes of these hazards are climate changes, seismic activity, but also incontrollable human activities like abusive land deforestation (not followed by coherent financially supported reforestation strategies). Environment protection problems focus on identifying the causes of natural disasters, preventing possible damages, globaly approaching the effects on short/long term socio-economical development.
