Modeling Landscape Evolution Due to Tillage: Model Development

摘要: Tillage erosion has been identified as an important contributor to the modification of agricultural landscapes. A two-dimensional, grid-based model developed compute soil redistribution and morphological changes complex landscapes due tillage operations. Soil movement along perpendicular directions tractor are computed a function local slope gradients characteristics implement. control volume approach is employed determine terrain elevation after each pass. The explicitly considers presence internal external field boundaries, simulating their influence on development deposition patterns. GIS layers used provide data, actual directions, borders, location other features, such vegetated strips, trees, or fences. was verified against analytical solution for bench terraces between strips. model's capability considering variable tested with simulation over synthetic, undulating surface investigate how implement's forward lateral displacement patterns direction relative slope. stability, computational efficiency, ability simulate fields boundaries varying allow its use practical tool within comprehensive conservation planning system.
