Mud stream formation conditions and mud stream hazardous areas of the Chechen Republic

Abstract

Mud streams in the mountainous zone are formed almost everywhere in the Chechen Republic: on the northern slope of the Main Ridge and its spurs, the Skalisty, Pastbischny, Lesisty, Terskiy, Sunzhensky ranges and in the depressions between them. The conditions for the mud streams formation and mud stream hazardous regions of the Chechen Republic are determined by orographic tectonic-geomorphological, geological-lithological, soil-plant, anthropogenic and especially hydrometeorological conditions and affect the mud streams with their indicators. The variety and complexity of the relief, as well as the temperature regime, are used to predict the mud stream threat and develop anti-mud stream measures. The authors of the article provide the following indicators: air temperature regime, also values of average monthly and annual air temperatures, monthly values of vertical air temperature gradients in the Chechen Republic territory, changes in annual precipitation (mm) with terrain altitude above the sea level on the northern slope of the Eastern Caucasus, schematic map of orohydrography and mud stream channels of the Chechen Republic on a scale -1: 500,000.
