Good landscapes depend on good drainage and so many fail because drainage is poor. Areas remain wet, plants die all because drainage is inadequate.

You need to know :

	Where sub-soil drains should be installed
	What material should surround drains
	Why the drainage of the base is more important than the sub-soil drains in most cases
	Why shallow profiles don't drain
	Why raised beds work better

Drainage is the science of how water moves within the soil and is collected and removed from a site. It is a complex subject governed by some complex soil physics. In a very large number of cases some of this physics has been simplified by teachers and others, resulting in completely wrong concepts being implemented into the landscape. The most common of these is that "water moves sideways in a soil at a reasonable rate", whereas in fact in almost all cases the sideways movement of water can be ignored, as only minute amounts of water are moved sideways in soils compared with downward movement.

This book deals with all aspects of drainage for sportsturf and horticulture in a way that has never been presented before. The complex aspects of soil physics, which make drainage such a difficult subject to understand, have been converted into Plain English easily understood by the practitioner and the student. At the same time the concepts have not been simplified, and they remain scientifically correct.

This book covers the following topics :

Soil Structure	How water gets into drains
Compaction	Perched Water Tables
Where & how to install drains	What is capillary fringe?
