Upload NowFactors affecting runoff may be divided into those associated with the precipitation, and the watershed characteristics. Factor # 1. Precipitation: Since by far the largest portion of precipitation occurs as rain, and the rainfall directly affects soil erosion, the characteristics of rainstorm and intensity, duration and frequency of rainfall are of interest in describing the […]

Several types of empirical expressions have been developed from time to time to predict peak rate of runoff from agricultural watersheds. Some of the most common expressions are described below: 1. Rational Method: The oldest and the most famous hydrological model of predicting peak rate of runoff is the rational formula, expressed as: q = […]
Understanding the Mechanics of Soil Movement by Wind
Article shared by :
Wind erosion is mainly a surface phenomenon and is influenced directly by wind velocity in various strata near the ground through which soil particles rise in saltation. Therefore, a brief discussion about wind structure near the ground would be necessary for understanding the mechanics of soil movement by wind. Wind Structure Near the Ground: The […]
