Practical Drainage is easy to read and presented in a non-technical style generously supported with helpful illustrations.
There are three key messages in this book:
These key messages are preceded by detailed descriptions of how water moves into soils and the effects of compaction on that movement.
The final chapters give step-by-step guidelines for calculating drain spacings and depths, based on measurements of the hydraulic conductivity of the soil and its various layers.
There are also chapters about how to measure hydraulic conductivity and how to design and install sub-soil drainage systems.
