This thesis is concerned with the characteristics
and development of scree slopes, as illustrated by examples from a small
alpine valley. The major controls of scree slope development and processes
are discussed with special emphasis on rockfalls and snow avalanches.
The results of debris accumulation measurements on networks of cleaned
boulders and polyethelene squares at seven screes from 1968-1972 are
presented and discussed. The techniques are suggested as a valid means
of measuring debris accumulation by avalanches. The surface sedimentary
characteristics of five screes are examined in detail with particular
emphasis on size sorting at various levels over the scree and possible
relationships between sedimentary characteristics and sorting. Detail
of the profile form of these screes is also given and the avalanche
modification of screes discussed. / Thesis / Doctor of Philosophy (PhD)
