channels should, therefore, be better understood for formulating arational plan to check the salinity hazards.90 Ghose, B., Pandey, S. , Singh, S. and Gheesa Lal. (1966)Geomorphology of the central Luni basin, western Rajasthan.Annals of Arid Zone. 5: 10-25The Central Luni Basin is drained by the Luni drainage system. Thecountry rocks are predominantly Malani rhyolite and Jalor graniteand Erinpura granite. The Luni with its tributaries has attainedmaturity. The relics of disorganised channels identified on the aerialphotographs of the region are at present partly truncated, buriedand disorganised. The region consists of 7 geomorphic divisions andfurther land units. They consists of (1) Siwana dissected plateau; (2)Jalor-Israna-Rewara granite-rhyolite interfluve with interveningplains; (3) The Khari-Bandi-Sagi riverine plains; (4) north andnorth-east alluvial plains; (5) Pachbhadra Salt basin; (6) Westernplain with dunes and (7) Flood plains of the Luni and Jawai-Sukridrainage system. The plains are flat and consist of older andyounger alluvia with sandy hummocks. The dunes are longitudinal,transverse and parabolic. The distribution of population andsettlement are more in the flood plains of the Luni and Jawai-Sukridrainage systems than in other geomorphic divisions.91 Ghose, B., Pandey, S., Singh, S. and Gheesa Lal (1967)Quantitative geomorphology of the drainage basins of the CentralLuni Basin in western Rajasthan. Annals of Geomorphology. 11:146-160The paper deals with the dimensional analysis of 12 drainage basinsselected randomly in the Central Luni Basin of arid Rajasthan.92 Ghose, B., Singh, S., Vats, P.C. and Kaith, D.S. (1975)Aerial photogrammetry and photogeomorphology applied toquantitative analysis of drainage basins for engineering planning.The Indian Geographical Journal. 50: 1-5The article deals with the photo-geomorphic interpretation andaerial photogrammetric techniques of quantitative analysis of thegeomorphic characteristics of small drainage basins and theirapplication in watershed planning. The drainage network and basingeometry characteristics such as basin order, stream length, basinarea and bifurcation ratio control the distribution of the surface runoffand discharge. These geomorphic characteristics, thus willprovide the guidelines to the engineers in selecting suitable sites toconstruct the reservoirs where maximum surface run-off can bestored. The measures of the dissections like constant of channel
