The coastal environment presents serious problems to land use due to flooding, erosion, pollution, and emerging threat posed by rising sea level. All these require constant monitoring and remedial action in order to preserve man¿s investment. The developments in the field of remote sensing by collecting multi temporal data through earth observing satellites make it possible to monitor the coastal zone effectively. This approach provides cost effective and accurate solution to various coastal management problems. In this study an attempt have been to analyze the changes in the coastal environment in Vasai creek, Mumbai using remotely sensed digital data. The shoreline behavior along the creek also analyzed in order to ascertain the stability of the coast. Water quality assessment using the visual interpretation was carried out and the dispersion of polluted water in the sea was studied. The changes in the land form features were quantified using unsupervised classification technique and which will be vital information for coastal planning for development works and protection works.The coastal environment of Vasai creek between the years Jan 1999 and Feb 2001.

Book demonstrate that ¿provision of insulation in residential building for thermal comfort¿. By this we get the information about need of energy conservation, and necessity of thermal insulation. An insulated home is more comfortable as the temperature remains consistent over weather changes .it makes the house comfortable and keeps the temperature of house cool in summer and warm in winters. Generally, there are four types of rating system. Using this we find which building is to be design.

Rapid industrialization, improper solid and toxic waste management practices in urban areas often lead to the degradation of groundwater, which then turns un-potable for future use. Ground water pollution not only affects the water quality but also threats human health, economic development and social prosperity. Suitability of groundwater quality of 5 bore wells and hand pump located in the sub-urban areas in Jalgaon city was assessed for drinking purpose based on the various water quality parameters required for the potable water in chapters 1 to 3. Also author suggest that, various test for quality parameters such as pH, Total dissolved solid (TDS), Temperature, conductivity, odour, colour, Turbidity, Hardness, Alkalinity, Chloride content, MPN are conducted on the collected ground water samples. The obtained results are compared with the drinking water quality requirement of WHO standard. From the comparison, the permissible and objectionable limits are decided and suitable treatments are recommended for the objectionable results which is covered in chapter 4. This book is most helpful in proper treatment of available ground water resources in the area for drinking purpose.

Slope stability and seepage analysis of earth dam is very important to ascertain the stability of the structure. The uses of analytical method of slope stability and seepage have gained popularity in recent years due to its capability to handle complex problems. The stability of earth dam depends on its geometry, its components, materials, properties of each component and the forces to which it is subjected. The design of earth dams involves many considerations that must be examined before initiating detailed stability analyses. Such as geological and subsurface explorations, the earth or rock-fill materials available for construction should be carefully studied. The research project focus on stability analysis carried out on Boradi village dam in Maharashtra in India and calculating results by using Geostudio software. The results of the factor of safety were considered to the Boradi village dam without water level, steady-state water level and water level drawdown by using analytical and Swedish circle method analysis to compare with Geostudio software method.
