Aerial photographs on a scale of 1:60,000 and Landsat imagery (bands 5 & 7) on a scale of 1:250,000 were interpreted to study landforms, soils, land use and land cover and the capability. Field traverses were made to confirm the air photo and Landsat image interpretation, especially for the present land use, land cover, soils and to identify geomorphically hazardous zones. Land use and land cover in the area are classified into twelve types, viz., wet crop land, dry crop land, land under horticulture, grass land and shrub land, southern tropical dry deciduous forest with red sanders, southern tropical dry thorn forest, roadways, railways, built up area, barren land, broken ground - dissection and erosion, and water bodies. The study area is divided into six classes of land capability based on landforms, drainage, slope, erosion, soil, groundwater potential and present land use. The data is presented in 4 maps (location and physiography, geomorphology, land use and land cover, and land capability). INTRODUCTION An area of about 1500 sq.km between lati tudes 14°00* and 14°15' N and longitudes 79°00' and 79°30' E of a part of Rajampet taluk, Cuddapah district in Andhra Pradesh is taken up for the study (Fig.l). The area has been affected by droughts during the last few decades. This work being the first attempt of its kind in this area, aims to study landforms and correlate them with land use and land cover. Aerial photographs (1:60,000), Landsat II imagery (bands 5 & 7), topographic maps (1:63,360) and field data are the main sources of information for this study. Topo graphic maps are used as base maps for transferring the data through photo inter pretation. Ground data through field studies have been collected to supplement and confirm the airphoto interpretation. The objective of the present study is to identify landforms, land use, land cover, land capability, and soil and to correlate the relationship among them, with a view to provide basic data to planners. Planning is needed for proper utilization of natural resources with minimum disturbance of the environment. Planning for resource utiliza tion of an area requires a detailed know ledge of the landscape, i.e., landforms, material composition, slope, land cover, present land use and surface and subsurface water conditions. It is aimed to collect information on a few of these useful aspects through remote sensing techniques and ground data. Physiographically the area is divided into (1) ridge and valley topography of Velikonda range, (2) gently sloping terrain of the Palkonda range, and (3) the fluvial plains of Cheyyeru, Pulang Eru and Patagunjana river (Fig.l). The three rivers are ephe meral in nature. The highest elevation is 1047 m above M.S.L. at Suddakoppu, east of Mangampeta. A majority of the hills fall in between the range of 300 to 800 m. Small hillocks and mounds in the altitudinal range of 30 to 100 m are scattered in the valley fill areas. The western part of the area exhibits a cuesta type of landform. The remaining area is occupied by valley fill and river built plains with the minimum local base level being 150 m. The climate is semi- arid to arid, with an average annual rain fall of 742.8 mm, over half of which is received during June to October (southwest monsoon). The summer temperature in May goes up to 34.5°C, the winter temperature in December goes down to 24.3°C. The study area is occupied by rocks of Dharwar (of Archaean), Cuddapah and Kurnool Super-groups (of Proterozoic). Granites and gneisses of Archaean age occupy a small area in the northeastern part of the study area. The rest of the area is occupied by rocks of the Cuddapah and Kurnool Super-groups. The important rock types in these two groups exposed in the study area are shale,phyllite, dolomite, limestone, quartzite, and conglo merate. The Velikonda range trends north - south. It is formed of folded shales and quartzites. The Palkonda range has cuesta slopes inclined to the northeast. Its trend is NW - SE. The Palkondas are formed of quartzites with dip slopes ranging between 10° and 20°. The study area is known for one of the largest deposits of barytes of volcanogenic origin at Mangampeta in Rajam pet taluk, and for substantial quantities of cement grade limestone. King (1872) first made extensive study on the stratigraphy of the Cuddapah Basin and classified the rocks. The Geological Survey of India has updated the geological map of Cuddapah Basin on 1:250,000 scale (G.S.I. Publication, 1981). A few geomorphic stu dies have also been carried out in the Cuddapah Basin (Vaidyanadhan, 1962,1964). Geomorphological maps on a scale of 1:250,000 was prepared from Landsat imagery by Naresh Bedi (1978). Geomorphological maps on a scale of 1:250,000 and 1:60,000 were prepared based on Landsat imagery and aerial photo interpretation of parts of Cuddapah Basin by Krishna Bhagavan and
