In terms of victims, floods are responsible for more than half the deaths caused by natural catastrophes. As flood events appear to be rapidly increasing world-wide, an advanced and universal approach to urban flooding and how to manage them becomes imperative to reduce flood impact.

Urban drainage and flooding, including urban drainage and solid waste interactions, sustainable urban drainage, and flood-resilient planning and building, flood insurance, flood proofing techniques, risk perception and preparedness and flood forecasting in an integrated manner are therefore extremely important. The manual integrates expertise from disciplines such as hydrology, sociology, economics, architecture, urban design, construction and water resources engineering and management.
