This book entitled “Disaster Risk Management” describing and analysing the spatial variations of disasters in general and floods in particular. Disaster is a serious disruption of the functioning of a society causing wide spread damages that exceed the ability of a society to cope with. Disasters are either natural or man-made. Some disasters are slow onset like drought, while others are rapid onset in the form of earthquake. The objective of this book is to provide readers with an integrated approach of understanding various disasters. It also attempts to analyse the factors of causing various disasters, adverse impacts, human responses and perceptions, forecasting and warning, emergency response, early recovery and Disaster Risk Management. Similarly, for Damage assessment and DRM various interdisciplinary techniques have also been applied.
