| Summary: | Field studies were undertaken on Banks Island, N.W.T., to investigate the. feasibility of using bank or slope morphology as an indicator of the lateral stability of coastal and riverine areas located in regions of permafrost. The study investigated the material characteristics and naturally occurring erosion rates associated with the range of bank or slope forms occurring within the study area. Morphologic features which were studied included repose banks, solifluction slopes, skin flows, retrogressive thaw flow slides, thermo-erosional niches, organic deposits and deflation features. The investigation indicated that the morphology of a bank or slope composed of unlithified sediments is related to the texture and ice content of the associated materials, and to the relative exposure of the site to fluvial or littoral processes of sediment removal. Each morphologic type was found to have a characteristic range of values for each of these parameters. Material genesis was also an important factor as it affects ... |
