Abstract

A series of 2D small-scale physical experiments were performed in the Ahlborn sediment
model bed tank (4.0×0.6×0.2 m) to investigate the influence of flow and sediment properties on soil
erodibility. A Soil Protrusion Apparatus (SPA) was developed to investigate the soil-hydrodynamic
phenomena under wet and dry conditions with smooth plastic bed tank (Jayaratne et al., 2010a). A
simple mathematical model on soil erosion rate for smooth bed was proposed using dimensional
analysis and a best-fit technique (Jayaratne et al., 2010b). The proposed paper discusses the extended
investigation on soil-hydrodynamic behaviour by increasing the mobile bed roughness to greater
values used in earlier experiments by the authors. A low cost technique involving spraying separate
solutions on to a drained flume will be used to freeze the soil bed geometry (Benson et al., 2001).
Proposed experimental work will lead to the comparison, calibration and development of predictive
curves of erodibility for different soils and verify the proposed mathematical model. Furthermore,
erosion rate prediction analysis will be investigated using computer programmes to simulate
interrelated changes in sediment bed topography for the better representability of the proposed
mathematical and physical model.
