Some problems of mudflows mapping

Abstract

Lack of identity of ideas on mudflow mapping on middle and large scales is noted as maps compiled by geological organizations usually don't show hydrometeorological conditions of mudflows formation and hydrometeorological maps of mudilows show but very little of geological and geomorphological data. Purpose of mudflow hazard map at middle and large scale is discussed. A proposition is made to compile middle-scale complex maps showing conditions of mudflow formation along with maps of mudflow hazard, Mudflow maps are mainly partial special geomorphological maps of applied significance; according to their contents they belong to analytic specific maps. Main principles are developed for legend construction for all three kinds of maps.
