The Water Complex of the Melera Valley

Abstract

In our issue for August 1945, Pp. 285-86, we published a review of a translation in English by Dr. Griffith, of the famous Emmenthal erosion expertmeni which had been carried out by the Swiss Forest Research Institute at Zurich for some 36 years. Prof. Burger has recently published further work on a similar subject in a Swiss valley in which the vegetation had been devastated but which has been under afforestation and protection for 10 years. This work and the Emmenthal work referred to above, give very interesting and important data on rainfall- intensity, runoff, and erosion and particularly on the, great effect the moisture condition of the surface soil at the time the rain starts, has on the resulting runoff. The fo11owing is a translation of the summary of this new piece of work. It will probably interest many of our readers who had the privllege of meeting Prof. Burger during their training but who may not now have success to his work.
