When drainage is understood and managed properly, the risk of flooding and damage to property can be greatly reduced. There may be limitations to what can be foreseen and catered for, but engineers, land managers and other professions have developed many techniques to minimise the effects of extreme weather events. This book provides a concise and clear understanding of what can and should be done to manage drainage across wide range of situations.
