Abstract
THE rapid rise in the standard of living of much of the world's population over the past few decades has caused many countries to give anxious consideration to their future water supplies. Even in Great Britain the problems of water supply and demand are requiring increasing attention' . In comparison with the advance of science in other fields the techniques for the study of the water relationships of catchment areas are somewhat undeveloped. In the United Kingdom there is much controversy about the hydrological effects of the afforestation of the hillsides the run-off of which supplies the big cities. In middle-western States of America the management of natural forests which cover the mountain catchment areas has been the subject of fierce controversy between irrigation, grazing and timber interests.
