The main objective of the study is to evaluate the physical characteristics and the natural resources in the study area and to develop methods for its efficient utilization and sustainable management using tools such as remote sensing and GIS. The thematic layers are derived from IRS-ID PAN + LISS-III merged satellite imagery and survey of India (SOI) topo maps using visual interpretation technique. These maps are converted to digital format using AutoCAD software and further integrated using Arc/Info and Arc view GIS software for the generation of final outputs. Physical characterization helps for quality of environment and natural resources development, which are optimally suitable to the terrain and to the development of water resources. The physical characterization of an area is also useful to plan the basic minimum needs of farmers, thereby improving their socio-economic conditions and helps in evolving a broad national policy which can be applied by decision makers for sustainable development of any given study area. This case study would help in developing municipalities with details at micro level for further planning.Keywords

India is primarily an agrarian nation with major portion of population depending on agriculture for their livelihood. About 83% of the total available water resources in India are utilized for agriculture. Hence, it is necessary to assess the water resources availability, progressive development and utilization for sustainable agricultural yield. This can be done both spatially and temporally using analytical procedures and models for studying the rainfall patterns, river water flow and its storage. An attempt has been made, therefore, to study the existing cropping patterns and water resources availability in drought prone area of Narsapuram watershed of Anantapur district in India.
The crop water requirements (CWR) for each of the existing cropping pattern is estimated using modified Penman method and information on existing water resources is obtained from the local government organizations. The correlation of existing ground water resources, its corresponding draft and the requirement of water for the existing cropping patterns have been studied, which revealed that the requirement of water for the existing cropping pattern is more than the water available in the Narsapur watershed of Anantapur district.
Various thematic maps, prepared from IRS IC LISS III satellite imagery and SOI toposheet, were integrated to prepare a composite map showing the status of ground water development and to identify sites for construction of artificial recharge structures. It is recommended that groundwater potential be improved through this artificial recharging of water to the aquifers so that it can meet the requirement of water for existing cropping patterns. This ultimately leads to increase in the crop yield and in turn increases per capita income of this chronically drought prone area for sustainable development. Therefore, an attempt has been made to suggest measures for increasing the groundwater potential by means of artificial recharge and to suggest suitable cropping patterns based on the type of soils and seasons.

The present challenge in front of Civil Engineers is to find alternative materials for fine aggregates in concrete. Since, most of the State Govt. banned the dredging of river sand. The Granulated blast furnace slag is considered as a fine aggregate in concrete. At present, in India Steel Industry produces about 40 Million Tonnes by 2020 it is estimated to 60 million tonnes. The Author has investigated the effect of compressive strength of concrete, when Granulated blast furnace slag is used (GBFS) as a fine aggregate in concrete. The work includes the partially and fully replacement of river sand by granulated slag in M25 Grade of concrete with a constant 0.45 W/C ratio. Slag replacement of 50, 80, 100% are used. It has been observed that concrete made with 50% of river sand and 50% (GBFS) is nearer to Zero percent replacement. Objectives: To determine the optimum percentage slag replacement as a fine aggregate in concrete which helps in maintaining sustainability of concrete and balancing between the environmental problems due to construction industry as it is necessary to find out the alternative materials for use as fine aggregates because of restrictions by the local authorities. Methods: The experiments are planned to find out the optimum replacement percentage of GBFS against river sand as a fine aggregate in concrete. Mix design for M25 grade of concrete is made with OPC (Ordinary Portland Cement) and PPC (Port land Pozzolana Cement) is considered with a constant 0.45 W/C ratio and slag replacement of 50, 80, 100% are used. 30 Cubes for each cement category of 150 mm size are casted, cured by immersion and tested by CTM. Findings: In both the cement category, the compressive strength and slump of concrete is found reducing with the increase in the percentage of slag as a replacement to fine aggregate. In concrete made with OPC when compared with 50%, 80% and 100% replacement with GBFS reduction upto 96.50%, 87% and 77.5% in strength and 84.6%, 53.84% and 34.6% in slump respectively is observed. In concrete made with PPC when compared with 50%, 80% and 100% replacement with GBFS reduction upto 95.30%, 80% and 63% in strength and 82.7%, 51.7% and 34.0% in slump respectively is observed. Application/Improvements: This study using alternatives to fine aggregate in concrete will help in making concrete economical, reduction in environmental problems and saving the natural resources. The study may be extended to determine the concrete sustainability in saline conditions also.Keywords

Earthquake is a spasm of ground shaking caused due to sudden release of energy in the earth’s crust and bulk of destruction takes place within a short duration of time. Past history records reveal that rate of occurrence of earthquakes is an increasing phenomena. Bitter experiences on failure/collapse of structures, particularly in urban regions, warn the people on importance of constructing earthquake resistant buildings. Local soil conditions and interaction between soil /rock media and the structure indeed affect the response of the structure during an earthquake. In the present investigation, the western region of Hyderabad, part of the capital of Telangana, is chosen as the study area which consists of different soil/rock profiles at different locations. Free vibration analysis of a multi-storeyed building is carried out when the foundation of similar structure rests on different soil/rock media. Frequencies and time periods are worked out for comparison when the same structure is assumed to be fixed at the base. From the results, it is observed that the variation in time period of the structure increases with decrease of soil stiffness. It is also noticed that soil-structure interaction effect on time period of the structure, particularly in loose soils, is of more significant compared to the variation in structure stiffness.Keywords
