Rainfall-induced soil erosion of a mountain area plays a significant role in supplying sediment and shaping the landscape. The related area of soil erosion, as an index of the changed landscape, is easier to calculate visually using some popular imaging tools. By image analysis, our work shows that the changing of the soil erosion area admits the structure of an S-growth curve. Therefore, we pr...

Climate change information at the scale of basin is vital for planning, development and use water. The Tapi climatically responsive. Hydrological response a based mainly on rainfall temperature. Variations in climate regional scales impacts fundamental features our life. Thus, present work, trend analyses time series (1971-2004) minimum, mean, maximum temperatures rainfallis performed monthly, ...

An interception model that links the temporal variability of rainfall with the storm-based description of the interception process is derived. Analytical formulae for long-term interception loss are obtained for precipitation with statistical characteristics derived from observations. The analysis of the results indicates that the point interception loss is controlled primarily by three time sc...
