Sediment Transport Analysis
This web-based, distance-deliverable course teaches engineering practitioners and college students the basic principles of sediment transport and the skills for performing sediment transport analysis using hydraulic models, such as the HEC-RAS4.1. The course consists of three parts: fundamental theories of hydraulic models, basis of sediment transport models, and application of HEC-RAS unsteady flow and sediment transport models. Practice examples are designed based on two dry land rivers in Arizona: the Rillito River and the Pantano Wash. Sixty percent of the content is the fundamental principles that govern flow and sediment transport in open channel flows, and 40 percent is regarding the application of HEC-RAS models. Concepts of bed material, bed load, and suspended load; formulas to predict bed load, suspended load, and total load; methods to estimate fluvial resistances based on bed forms (e.g. ripples, dunes, antidunes); calculation of local scour and bank erosion; and design of stable channels are also included.
