Soil erosion vulnerability mapping using remote sensing based MMF rule in parts of Coimbatore and Tiruppur districts – Tamil Nadu, India

摘要

Soil erosion assessment is a capital-intensive and time-consuming exercise. A number of parametric models have been developed to predict soil erosion prone zone at structural terrains, even though Universal Soil Loss Equation (USLE), and its updated or modified versions are most widely used empirical equation for estimating annual soil Loss. Morgan, Morgan and Finney 1984 proposed a model on field base information and estimation had yielded point-based accuracy values. But on carrying out its original form in conventional method like Remote Sensing (RS), it is quite varying in limits on measuring the hydrologic parameters on spatial scales .Even Some of the inputs of the model such as cover factor and to a lesser extent supporting conservation practice factor and soil erodibility factor can also be successfully derived from remotely sensed data.
