Book Description
Sediment deposition occurs in the lower reaches of the concrete-lined Corte Madera Creek flood control channel because the elevation of the channel bottom is below sea level. These sediment deposits, combined with the presence of tube worms and barnacles on the channel walls, reduce the flood-carrying capacity of the channel. The upstream portion of the original flood control project was not completed and flood flows above 3,000 cfs are not contained in the natural channel upstream. Thus, there is reduced flow competency to carry the coarse sediment load delivered by flood flows. With annual maintenance and upstream containment of breakout flows, most of the sediment deposited in the concrete channel from seasonal antecedent flow can be washed out by the time the flood peak occurs. An HEC-6 numerical sedimentation model study was conducted to evaluate several alternative plans to provide flood containment and sediment storage while also maintaining the natural characteristics of the upstream channel.

Managing Flood Risk

Book Description
The past half century has seen an evolution in thinking from ‘flood control’ to ‘flood risk management’, recognizing that risk results from both hazard and vulnerability. Rather than rely only on engineering structures to reduce flood magnitude or extent, recent policies emphasize avoiding construction in flood-prone areas (or moving people from floodplains), reducing impacts on exposed populations through early warning systems, and insurance to aid in recovery. Implementing this new approach faces many challenges but also offers opportunities for synergies, as described in this book for a range of large floodplain rivers and smaller urban streams across North America and Europe. This book is unique in presenting the voices of those on the front lines of implementing a new paradigm in flood risk management, each river with a unique set of challenges and opportunities derived from its specific geography as well as differences in governance between the American and European contexts.
