NAS Press | 2013 | ISBN: 0309130581 0309130573 9780309130578 9780309130585 | 135 pages | PDF | 17 MB

This book examines the factors that affect flood map accuracy, assesses the benefits and costs of more accurate flood maps, and recommends ways to improve flood mapping, communication, and management of flood-related data.

This is an important tool for individuals, businesses, communities, and government agencies to understand and deal with flood hazard and flood risk.
