Abstract: This paper presents theoretical results obtained under research contract about the pluvial soil erosion and landslide prognosis. The presented results refer to a reformulation of the USLE model in the spirit of theoretical physics, in order to modeling the pluvial soil erosion phenomenon as dynamic process. There are many problems to be solved in the direction of the USLE model formulation in the language of the modern physics: USLE formula must be express in variables which depends by space and time; the replacement of the particular physical quantities characteristic of this model with universal physics quantities (for example, like the hydraulic models for soil pluvial erosion); the application of the general principles of physics to modeling the transformation of the geometry of the eroded surface; introduction of the random elements in the model. Another research direction is currently redrafting USLE model in terms of vectors. This model divides the year int!
o time units. The issue presented here is not exhaustive. In this paper is addressed only the first two problems. To check the results obtained, is used experimental data obtained using a mobile installation to estimate the risk of pluvial soil erosion. In aim to replacement the particular USLE model variables with universal (not particular) physical variables, is used the tool of the dimensional analysis. The results and their verification, show that the proposed formulation for USLE is plausible. With this material I hope to attract in this direction other researchers in the same category of phenomena. The new formulation can be a start to much new research.
