For this purpose, a widely adopted computer model 'DAMBRK' is used. In this model, complete Saint-venant equations in one-dimension are used as governing equations for channel muting. An efficient four point presimann scheme is used to perform the numerical solution of these governing equations. The necessary data set has been collected through various sources and for the unavailable data; certain assumptions were made according to suitability of the required conditions. A sensitivity analysis is performed to study the effects of breach width, time of breach development, and bed roughness on the flood wave propagation due to dam break flow. Comparative analysis has been done using NWS (National Weather Service) and MIKE 11 models for the evaluation of flood wave routing and estimation of travel time for dam break flow along with the water level and discharge in the downstream of the dam at different locations. This study is focused at determining the temporal and spatial variation of water surface pm file and discharge.

A total of six different samples of MSW has been taken and anaerobically digested in Oxitop serum bottles and their biogas and methane generation potential is studied. It is inferred that around 45% of the biogas generated is methane taking into account that the gas collection was carried out with glass syringe method, which is an approximate method. The Biogas generation potential and the bio methane potential of three major Indian cities namely Delhi, Mumbai and Hyderabad had been studied by installation of three anaerobic reactors of 10 L capacity. The theoretical methane and biogas generation are compared to the experimentally derived results. The MSW of Hyderabad city has the potential to generate 2.19 * 106 m3 methane per year. The Delhi MSW could generate around 3.87 * 106 m3 methane annually and the Mumhai MSW has a potential to produce around 5.30 * 106 m3 methane annually. Also, the characterization of the MSW had been studied for the influent and effluent samples experimentally. It had been found that the concentration of arninonical nitrogen increases and the concentration of nitrate and total phosphorus in the samples decreases at the end of anaerobic digestion.

A wide variety of methods have been developed in this concern. During this study, remote sensing images and GIS were used for climatic impact prediction in Uttarakhand, during the years of 1990-2010. It was assumed that climatic impact could be predicted using time series satellite imageries. Natural vegetation, urban area, forest cover etc. were chosen as main landuse classes to study. Rainfall and temperature data were used to find the effect of climatic change. Landuse/ Iandcover classes within several years were prepared using satellite images. Maximum likelihood supervised classification technique was adopted in this work. The detected changes in landuse classes were correlated with temperature and rainfall data of twenty one years. Landuse change index and climatic change index were created and find correlation between them. By the correlation of landuse change index and climatic change index it was found that Haridwar, Udham Singh Nagar and Dehradun districts were highly affected due to climatic change. Significant differences were observed as increasing temperature and decreasing rainfall. Finally, graphical models were used to present the changes.

In this study a logical procedure to evaluate the fire introduced stresses along with the impact on a nuclear containment subjected to an aircraft crash is suggested. The intensity, duration and distribution of the fire are determined based on aircraft crash analyses and characteristics of jet fuel. To predict the response of the BWR Mark Ill type containment Abaqus [1/lmplicit finite element code was used. For the impact analysis Reira[14] force history curve was used to apply the load on the containment. Both the heat transfer analysis and thermal stress analysis were done by taking the material properties based on the conditions and type of analysis. In order to predict the behavior of concrete, the concrete damaged plasticity model was employed while in order to predict the behavior of reinforcement the Johnson-Cook elasto-viscoplastic material model was used. The crash of the aircraft was considered to take place at midpoint of the cylindrical portion. The properties of the material at elevated temperature were taken from Euro codes Sat, 01 Jun 2013 00:00:00 GMT http://localhost:8081/jspui/handle/123456789/20713 2013-06-01T00:00:00Z
