One-dimension mathematical model of energy parameters of a hyper concentrated mudflow.
2020
Natural anomalies, mudflows in particular, put many world countries before serious problems trying to develop thorough engineering solutions to combat mudflows. Mudflows are one of the dread natural calamities and relevant regulation measures are associated with the identification of their genesis, dynamics and energetic parameters. The work specifies and assesses the bed processes taking place during the mudflow movement through mudflow channels and the plans to calculate the energetic processes of currents based on the methods and scientific-technical approaches commonly accepted in hydraulics and hydraulic engineering. The problems planned in the article are solved by using classical scientific approaches and experimental study methods. The practice has evidenced that the selection of the models of the regulation measures within the action zones of mudflows needs improvement. The article, by considering the flow rheology and based on the energy equation, deduces the differential equations of uneven flow movement for different values of a bed gradient, in case of permanent and variable mudflow discharges. The obtained results allow predicting the energy parameters of the mudflow motion through non-prismatic beds by considering both, the permanent and variable value of the current discharge.
