Frozen soil effects on the erosion hazard. Research technical completion report, project A-070-IDA Item Info
![An examination of past erosion events shows that erosion and sediment yield affected by frozen soil are usually worse than that occurring on unfrozen soil. The objectives of this project were to determine if these observed differences were real or not and also if the severity of erosion in the early winter had any effect on the severity of erosion in the late winter or spring. The changes in surface roughness of three plots were determined as a function of the freeze thaw cycles. Runoff energy and sediment yield were classified as to whether they occurred on frozen, thawing or unfrozen soil. It was found that there were significant differences in runoff energy and sediment yield from snowmelt or rainfall on frozen or unfrozen soil. Sediment yield from runoff occurring on thawing or frozen soils was the same and was significantly different from rain on unfrozen soil.
