Effect of vegetation on lateral migration of anostomosed channels of a glacier meltwater river

The effect of groundfrost on erosion by meltwater in Geographical essays in Hungary.
The factors influencing surface denudation by meltwater are bedrock and soils| weather| relief/slope conditions, exposure| anthropogenic activity. Landforms are linked to the combination of geomorphic processes. (DLO).

lakes receiving glacial meltwater is discussed. Sediments from four lakes receiving glacial meltwater are discussed, and then compared with sediments from a lake not receiving glacial meltwater. Characteristic differences were observed in the inorganic

Assessing the global meltwater spike

Assessing the global meltwater spike
, and J. S. Killingley (1977, Nature London 269, 661-663) and W. H. Berger (1978, Deep-Sea Research 25, 473-480) reconstructed meltwater spikes similar to those actually observed in the Gulf of Mexico and thus apparently confirmed the Worthington
hypothesis. It is shown that this conclusion is unwarranted. The primary flaw in the reconstructed meltwater spikes is that the mixing intensity used in the deconvolution operation is overestimated. As a result, structure recorded in the mixed isotopic record
of the foraminifera carrying the isotopic signal, and analytical error. An alternative geographic view to the global low-salinity lid is offered: a map showing portions of the ocean potentially affected by increased deglacial meltwater at middle and high latitudes

over 400 m deep channels were cut into the underlying substratum by a combination of glacial erosion and meltwater activity. The channels were active until the Late Elsterian and were subsequently filled with meltwater deposits and glaciolacustrine silt

Sediment source for meltwater deposits

The major objective of this research was to quantify the outflow of meltwater and precipitation-generated runoff from the region that lay on and adjacent to the southern margin of the Laurentide Ice Sheet, during a major period of glacial melting

The main aim of this paper is to examine geomorphic activity in the central Karakoram, between 3 000 and 6 000 m, where precipitation seasonally released meltwaters and freeze-thaw cycles are relatively abundant. Glacier ablation zones compose

The principal tasks of this paper are to provide estimates of total meltwater-stream sediment yields, and assess the importance of fluvial processes in modifying these yields, in order to assess the importance of fluvial processes in transporting

The thesis treats the radiation budget at elevations above 1500 m a.s.l. The factors controlling the meltwater production in glacierized basins are considered. As a synthesis, one chapter is devoted to radiation balance. The results could prove

-20 cm. Spatial variations in eolian additions and meltwater produce complex patterns in chemical weathering of fines beneath large snow patches, although the nature of clay-mineral change is typical of humid, temperate, mid-latitude environments.

This system covers some 51 per cent of the bedrock surface area, and is believed to have transported the bulk of supraglacially-derived meltwaters through the glacier. Using the cavity hydraulics model of Kamb (1987), it is shown that the geometry
