Abstract

The study of changes of sediment beds is of the issues which has attracted River engineers. Attention to investigate the rate' of scour and sedimentation is significant in bend of rivers rather than straight rivers. The change of bed topography, scour and sedimentation pattern have caught the attention of hydraulic engineering profession. This paper examines the topography changes using experimental data in 90 degree bend and bend with T shape spur dike in outer bank. For this purpose interpolate methods such as IDW, KRIGING and SPLINE Tension used to convert point measurement to continuous surfaces. Accuracy assessment accomplished by validation method. The result showed that KRIGING methods have best accuracy to create surfaces for studying bed topography in Bend Rivers.
