MAQOLA ANNOTATSIYASI

quote
This article discusses the method of determining the design characteristics of mudflows. The issues of volumes of previously passed mudflows, methods of their identification are considered. One of them is topographic survey in combination with sinking of pits, drilling or other types of determination of the sediment capacity of each generation. If these methods do not allow to determine the volume of 149 the mudflow in a direct way (removal of mudflow deposits into a large watercourse, difficulties in isolating each generation of mudflow, erosion of the removal cone, etc.), then an analytical method can be applied. The article considers the issue of the size of the mudflow - its estimated (maximum) width and depth - necessary for the correct determination of the dimensions of the mudflow structures, as well as for the calculation of the flow rate. The mudflow velocity, which is difficult to directly measure during the flow, is still determined using analytical formulas
