Description :
Air photo interpretation and field survey were used to examine rates and patterns of planform change over the last 40 years on an 80 km reach of the Luangwa River, Zambia. The river is a medium sinuosity sand-bed river and cutoffs on meandering sections are frequent. The role of spatial variation in bank resistance in controlling meander development is examined. The kinematic wave model is operated within an Arc/Info GIS framework. Channel change in this area, is highly significant to humans in that within the South Luangwa National park a number of safari lodges are sited on the outside of meander bends and are threatened by bank erosion.
