Abstract: Sundarbans Reserved Forest hosts the largest single block of tidal, salt - water mangrove forest on Earth with a diverse collection of flora and fauna, including many endangered ones. It is thus, (and also generally) necessary to find an appropriate estimation of the recreational benefits of this world - renowned region as a tool for the conservation of biodiversity, as well as the devel opm ent of ecotourism, there. This report has been designed to do just that (estimate the recreational value) and to exhibit a relationship between the Sundarbans Reserved Forest (SRF) in Bangladesh and travel cost, using the responses of the visitors to th is region from all over Bangladesh. A zonal approach of the travel cost technique has been u sed here and the sample was 300 visitors of SRF over a period of seven days. The analysis yielded that the total value of the environmental resources of SRF is arou nd 197 million Tk./year. A suggestion has also been made of initiating an entrance fee of 50

Abstract: A concrete gravity dam is a major hydraulic structure which resists all external forces by its weight. Consideration of earthquake force is a major concern for the construction of major structures like dams. The main objective of this study is to obtain the design base width of a dam for different seismic conditions by varying the earthquake coefficients in both vertical and horizontal directions. This has been done by equating the different factors of safety for a dam with their limiting conditions under both tail water and no tail water condition. The shape of the Mettur dam in India is considered for the study. In the study the base width was calculated using Newton Raphson method in C++ and their variation plotted. A study on the variation of uplift pressure with change in the position of drainage gallery and the total uplift force and moments were obtained. A comparison was done in the design base width obtained for a particular case of earthquake without drainage g allery to the
