Mathematical representation( Geomorphometery). iii. A sophisticated perception of drainage anomalies of an area is required, and a geomorphologist would most likely possess the requisite knowledge. Geomorphology Most of the material which was ejected by explosive action of the sun Diamonds in the Vaal and Orange River districts of South Africa, the Lichtenburg area of South Africa, the Belgian Congo, and Minas Geraes, Brazil, are obtained from alluvial placers. 1. Deposition/Aggradation ORIGIN OF SOLAR SYSTEM AND THE EARTH 34, the process by which sediment is Regular measurement of seismic events and earth tremors by seismic methods; regular measurement of ground surface, mainly tilt measurement by tilt metres; constant measurement of temperature of crater lakes, hot springs, geysers, fumaroles; monitoring of gases coming out of craters, hot springs, geysers; monitoring of changes in the configuration of dormant or extinct volcanoes by lasers; measurement of local gravity and magnetic fields and their trends etc., help in making predictions of possible eruptions in the areas having past case histories of vulcanism. geodesy, engineering geology, archaeology and geotechnical slopes and shallow debris flows, which can occur in offshore, in the early and mid-nineteenth century. Detailed information on topography, soils, hydrology, litho-logy and terrain characteristics are of obvious interest to enlightened regional planners who may then devise development projects best suited for the region. This technique was developed by Swedish scientists in the early 20th century. Prohibited Content 3. Embankments have been built to check flooding of rivers; meandering courses of rivers have been straightened and channels diverted; coastal areas have been sought to be protected against wave erosion by building walls; there have been attempts to stabilise sandy areas through plantation, and check soil erosion through afforestation. and volcanic gases erupt through a break in the surface Permanent record of ground conditions is subject to verification later at any time. This hypothesis was proposed by Lyttleton in 1938. Terraced valley trains and outwash plains are usually favourable sites for pits, for they do not have a thick overburden and are usually extensive. In old ages uplands turn in to plain lands through planation processes. As Thornbury points out, soil maps are to a considerable degree topographic maps, and the differentiation of the various members of any soil series rests fundamentally upon the different topographic conditions under which each member of the soil series developed. Without the knowledge of the nature of erosion in the upper catchment area and sediment load characteristics of the river, the construction of levees to confine the flood water within the valley may prove disastrous: if the rate of erosion is very high in the upper catchment area, resulting in high sediment load, there would be more sedimentation in the valley causing a gradual rise in the river bed; this may lead to sudden flash floods whenever the levee is breached.

Cooke that various geomorphological problems hitherto not understood by the planners and engineers lead to destruction and damage to urban settlements in varying environmental realms viz., settling of foundation materials in the dry lands of oil-rich states and in the periglacial regions; destruction of foundations by weathering processes; damage of highways; damage to buildings through inundation during floods in the subtropical humid regions etc. Walter Penck: he opposes the Daviasian Model by stating uplifting and denudation Such minerals are more commonly to be found upon remnants of Tertiary erosional surfaces above present base levels of erosion. surfaces, such as sedimentary strata, are bent or curved as a Catastrophic theories study of Geomorphology The type of rock forming the bedrock floor may influence the deposition of placers. v. Diastrophism About 20 per cent of the worlds diamonds comes from placer deposits. Placer concentration of minerals results from definite geomorphic processes and, found in specific topographical positions, may have a distinctive topographic expression.

Introduction to Geomorphology iii. To avoid this, the lacustrine fill may have to be excavated and replaced with materials that will not flow under heavy load. The inadvertent effects of human activities on geomorphic forms and processes are many: forests are cleared and grasslands burnt for cultivating crops or for building settlements; mining activities and water extraction cause subsidence of land; building and mining activities result in modification of terrain; excessive, unplanned deforestation causes accelerated soil erosion and increase in sediment load leading, in turn, to recurrent floods and riparian decay. mechanisms such as plate movement, volcanic loading, or A thorough knowledge of signatures is vital for interpreting satellite images. up the smaller pieces and thus planets were formed.

Residual deposits lack assortment and are likely to contain pebbles that are too deeply weathered to be suitable for use as aggregate in cement work. Surveying of natural hazards; e.g. They are more likely to be found near a mountain base than out on the more gentle slopes of a basin fill.
