The environmental and economic zones of coast and monitoring of the dangerous natural phenomena
For the organization of effective hydro-meteorological monitoring at sea coasts new principles of division into districts of sea coasts are offered. The analysis of the data on coasts of the seas in the European part of the Russian Federation has shown that they have to take into account the composition of the dangerous natural phenomena and processes, other natural and economic criteria. For each environmental and economic zone of coast and its sub-areas there is a special set of the hydrographic, hydrological and economic-geographical characteristics that influence the composition and probability of natural hazards. The dangerous natural phenomena have as much as possible negative influence on the population and economic activities in the river deltas and coastal areas of the river and mixed types.
