wentworth and Smith method of slope development?
Answers
Answer:
The possible mode of the origin (not process) can be supplemented by the background of previous discussion. The various methods of slope analysis have been suggested by Pinsterwalder, S. (1890), Smith, G.H. (1935), Wentworth, C.K. ... In the present study two methods have been adopted for the study of average slope.
C.K. Wentworth's Method:-
(i) C.K. Wentworth's Method of Average S.Pc
In 1910 C K dn-cloced a simplified method for determining the average .lo, of land surface lie devised a 'general and random' method of determining average slope over an area from a neap According to this lirstls the contour map of the area is costred with an east-west, north south grid, tlxd contour crossings are sainted then tabulated for determining the average number contour crossing per mile The procedure was repeated using an oblique gaol mei the same area .ind the asensge number of contour crossings per mile determined Fie then applied the following formula to determine the tangent of the awl, angle of slope of the Land surface.
G.N. Smith's Method:-
(ii) G.N. Smith's Method of Slope Analysis
According to this nic NA, the topological shed is rhyded Imo rectangles of 5 minutes each by longttude and latitude Then the difference in height between the highest and lowest point in each rectangle is calculated and plotted in the centre of each square on a small sale base map IsopIctIts arc drawn for each ICC ft to indicate areas basing the same amplitude The map is then shaded in different tints to indicate ergs with same 'local relief Further information is obtained by mcasunng the are of each 'relief province' and then “pressing each am as a per of the loud lard area This method is effccust in maturely dissected plains and plateaus. but does not provide saustacsor, results in mapping the complex topography
