Summary on Grant Application Form |
|
Most rivers contain an undulating bed topography of alternative pools (scours) and rifles (shallows) whose spacing scales with the channel width. The pool-rifle unit is the fundamental morphologic control on flow structure, bed scour and sediment dispersal. In upland rivers the pool-rifle unit may locally accumulate sediment, leading to potential flood risk and bank erosion. This project will use an integrated physical and numerical modelling approach to help manage dynamic upland rivers with marked pool-rifle topography.A laboratory scale model, based on an upland, urban channel in Todmorden, N.W. Yorkshire, will quantify the effect of changing flood height on flow and sediment transport within the pool-rifles unit. This model geometry will then be used to develop and test numerical models of flow at different stages of pool-rifles submergence. These models will simulate sediment transport and assess the impact of Weir and artificial concrete channel construction on pool-rifle morphology.The end product will be both a detailed quantification of flow within the pool-rifle and a user-friendly numerical model for use by environment Agency River and flood defence management.
