Abstract

As part of the development of improving the methods of integrated monitoring of mudslides, a software shell of the electronic information resource «Mudflow Phenomena Database» (DB) was created. The developed database covers the issues of organizing the accounting of data on mudflow events based on the materials of complex and operational (space, ground route, etc.) monitoring of mudflow basins, as well as archival data for each of them. The purpose of this database is to provide an up-to-date information basis for assessing the current spatial and temporal changes in monitoring objects of mudflow basins, based on the results of analytical study of the replenished data. The information basis consists of information that allows us to assess the conditions of occurrence of mudflow processes in the region, their type, genesis, volume of the solid component of the mudflow, frequency, intensity, basic morphometric indicators of mudflow basins, etc. The analysis of the materials presented in the database makes it possible to identify the scale, danger, main features and patterns of the spread and development of mudflow activity. The database of mudslides, depending on the structure, content and form of search queries, can be compiled for different hierarchical levels of geographical, territorial and administrative division of the region and mudflow basins. The first part of the article describes the structure of the input information, justifies the choice of parameters to be taken into account.
