ABSTRACT
This chapter illustrates the use of the CES-AES methods through a series of practical examples involving stage-discharge, velocity, backwater and afflux prediction for a range of channel types (size, shape, cover). Generic guidance on the use of the CES-AES for different flood risk management activities is provided, with specific examples relating to availability of site information, vegetation maintenance and dredging. A series of ‘what-if’ scenarios is explored to demonstrate the sensitivity of the CES-AES outputs to changes in input data (roughness, slope, sinuosity). An approach for estimating roughness in mountain streams with boulders is presented.
