The forecast system has the advantages in combination of regions and ravines, rational compounding of time and space scale. The project, which has debris flow forecast models of Sichuan province, Liangshan district and single ravine, can forecast debris flow in 3 layers and meets the demand of hazard mitigation in corresponding layer.展开更多

The options available for prevention/elimination of the hazard of limited drinking water supply to the public are described. Current climate and, in some countries, also the existing social conditions pose barriers to a smooth water supply to the public. Various hazards endangering the quality and amounts of water produced emerge. Since the risk of water supply outages due to natural or anthropogenic factors cannot be completely eliminated （for instance, hacker attacks pose a new threat to the water companies＇ control systems）, in other words, emergency situations where smooth water supply is disturbed cannot be ruled out, efforts must be made to at least minimise adverse impacts of such events on the users. Organisational and technical conditions minimising such hazards must be set up. A water production and distribution organization and management system must be introduced, which will be able to prevent and address such hazards and emergency situations. How to tackle this complex task in the real water system management conditions and to assure some minimal amount of water at least for strategic consumers is discussed in this article. The results of a water system operation risk analysis are presented, feasible methods to minimize such risks are described, and options to prevent and address such risks are proposed. A water company organisation and management system taking into account the possibility of development of emergency situations is set forth. Focus is on the use of a telemetric system as a system means that facilitates the prevention and possible addressing of any emergencies occurring during the operation of a water supply system.展开更多

At present, there are some 30 research sections and teams specializing in the subject and staffed by more than 1,700 professionals in the CAS system, including six CAS members and some 500 mid-ranking or senior researchers. It is expected that the number of doctorate and post-doctorate scholars flocking to the field are in rapid increase.
