This book covers the theory of hydrology from the basic water cycle through to open channel flows and precipition analysis in an easy and clear manner. It always points out the different analysis approaches giving a balanced and broad approach. To compliment this detail is given on the practicalities of field work and equipment needed to actually go about collecting the required data for the theories. Essentially a well balanced view of all aspects of hydrology - enough detail to be useful but not so much theory as to bog you down. I recommend it :-)
