Abstract: Rational selection of the most appropriate technological alternative to deal with diverse environmental problems and issues, including wastewater treatment, is a big challenge in the field. The interrelated and complicated nature of the problem has made the process even more difficult. There are many environmental, public and cost related issues to be addressed while selecting best technological alternatives. Therefore, there is a need to have a simplifying tool to help in decision making. Environmental decision support systems (EDSS) are specific computer systems that are designed to help decision makes, managers, and advisors locate relevant information and carry out optimal solutions to problems using special tools and knowledge. In this paper a detailed discussion of TMSES, an expert decision support system we have developed to assist in making preferences over some secondary wastewater treatment technologies, is given. The paper also gives overviews to expert systems.

Abstract: The resources planners usually aim at identification or development of possible resources system, design or management plans and evaluation of their economic, ecological, environmental and social impacts. In this, single or combined decisions are sought on selection, sizing, target fixing, operation, capacity expansion, and financial planning etc in respect of a system. Since the late 1950s, system methodology has been successfully used to develop various techniques for solving classical systems planning problems and their extensions and as such many techniques namely, linear programming, nonlinear programming, mixed integer programming, Dynamic programming, simulation etc. are being widely used nowadays. In the present study a model is developed for maximizing the returns with the associated utilities assigned to each crop by fuzzifying the cost coefficients of each crop. Then an optimal cropping pattern which gives maximum returns from the command area under specified constraints, namely irrigation intensity, land and socio-economy is selected.

Abstract: The Muskingum method of natural stream flow routing, first developed by McCarthy [1] for flood control studies in the Muskingum River basin in Ohio, is a widely used hydrologic method, for routing flood waves in rivers and channels. The application of the Muskingum model to flood routing in natural channels has some limitations because of its inherent assumption of a linear relationship between channel storage and weighted flow. Many nonlinear forms of the Muskingum model are also proposed by recent researchers, for better prediction of better outflow hydrograph of a river reach. However, recently, a soft computing based tool, Genetic Programming (GP), which is an offshoot of Genetic Algortithms, has shown to have the ability to recognize input-output relationships. It is a relatively new approach for solving flood routing problems which is found to give excellent results with minimum errors. Hence, an evolutionary algorithm-based modeling approach ' Genetic Programming ' is proposed for flood routing in natural in natural channels, which is found to route complex flood hydrographs also with highest accuracy as compared to all traditional methods. The proposed method is applied to standard example of single peak hydrograph from a data set from Wilson [2], as well as for routing of a multi-peaked hydrograph through a natural river channel reach, along the Sabinal River, Texas (USA). It is observed that the GP model performs extremely well with a root mean square error (RMSE) 0.3396 m3 /S for single peak hydrograph and 0.359 m3/S for multi-peak flood hydrograph. These RMSE valued are almost twenty five percent of second best method in routing single peak and multi-peak hydrographs.

Abstract: Flood is the most devastating natural phenomenon that affects the society, especially poor people who are vulnerable to disaster due to limitation of their resources. Most of the natural disasters in Mumbai are related to flood and causing maximum damage to lives and properties in comparison to other disasters. India is one of the worst flood-affected countries, being second in the world after Bangladesh and accounts for one fifth of global death count due to floods. About 40 million hectares or nearly 1/8th of India ' s geographical area is flood-prone. Critical facilities being the backbone of any economy or society, any damage to these infrastructures may cripple the economy of the country. So, this study was carried out to create flood vulnerability map of Mumbai City using GIS techniques.

Abstract: The performance of sewage treatment plant is natural expectation from sustainable environment which is found frequently fluctuated in its own. There may be numerous reasons for such fluctuation and they may be rectified with necessary measures by inspecting various operations of sewage treatment plant ranging from macro level to micro level. But an essential element is to monitor the performance of sewage treatment plant which is nothing but the performance evaluation of sewage treatment plant. There are various methods available for the same but the present era needs fast computing techniques for the determination of such performance and computers are the best solution in such regard. This paper is an attempt in the direction of preparation of methodology which merely gives a tentative approach of performance evaluation of activated sludge process for small to medium scale sewage treatment plant.

Abstract: Wetlands (and lakes) constitute the most productive ecosystems with a wide array of goods and services. These ecosystems serve as life support systems; serve as habitat for a variety of organisms including migratory birds for food and shelter. They aid in bioremediation and hence aptly known as ' Kidneys of the Landscape ' . Major services include flood control, wastewater treatment, arresting sediment load, drinking water, protein production, and more importantly recharging of aquifers apart from aiding as sinks and climate stabilizers. The Wetlands provide a low cost way to treat the community ' s wastewater, while simultaneously functioning as wild fauna sanctuary, with public access. These ecosystems are valuable for education and scientific endeavours due to rich biodiversity.

Abstract: Recent decades have witnessed much of global attention towards sacred groves, once globally practised conservation of forest patches by especially farmers from pre-historic periods. Due to various reasons, such practice faded away from the world. India continues to have many regions still rich in sacred groves, the Western Ghats being one such. Although the sacred groves in relation to biodiversity and culture are better studied, details on ecosystem services from them are a big necessity. The current study in the Karikan sacred grove of Uttara Kannada Western Ghats in Karnataka specially focuses on how this grove has a celebrated role in conservation history by sheltering a good population of dipterocarps of primeval forests, in all stages from saplings to large trees. The biomas and carbon sequestration services rendered are of high order, and also paving the way for regenration of several climax species including the unique dipterocarps. The high percentage of endemic vegetation that Karikan encompases is mainly on account of dipterocarps, notably Dipterocarpus inicus. This study also covers an adjoining secondary forest where D. indicus is entirely absent from saplings to trees. At the time most other species present in the grove are regenerating well here and a secondary climax has been attained. The biomas level is comparatively much poorer despite the secondary climax. This study, while acknowledging the importance of conservation of sacred groves, also highlights the need for application of ecological methods to distinguish climax forests from secondary climax forests which often grow in mosaic in the Western Ghats. This helps in understanding forest ecosystems for location-specific management regime

Abstract: A major complicating factor in water resources system management is handling uncertainty. Reservoir management is one of the complex problems which include the uncertainty. Hence optimal operation of reservoir has been an active area of research for so many years. Various techniques have been developed and adopted in the reservoir operation, which has considered the uncertainly involved with the randomness of inflows and or demands. In the present study, Fuzzy Stochastic Dynamic Programming model is developed to decide operating policy for reservoir, namely Jayakwadi reservoir stage-I on the river Godavari in the state of Maharashtra. A basic concept of stochastic nature of inflows and development of Fuzzy Stochastic Dynamic programming model is explained. The Stochastic Dynamic programming model takes care of the stochastic nature of inflows into the reservoir while sigmoid membership function is taken for fuzzy objectives. This model (FSDP) is implemented to Jayakwadi Reservoir Stage-I to decide operating policy. From the results it can be seen that the both the irrigation and hydropower achieve more than 90 % satisfaction level.

Abstract: It is estimated on a global scale that humans are now using over half (54 %) of the world ' s accessible supplies of renewable fresh water and that by the year 2025, three quarters of the world ' s renewable fresh water supply will be committed. With increasing demand for fresh water supplies, the use of treated wastewater is a feasible way to supplement the global water resources. It can be an economical and feasible proposition. In recent years, land application of treated municipal wastewater has been heralded as an alternative to treatment and direct discharge to waterways. Various degrees of pretreatment of wastewater are normally required before applying it to the disposal site. In India much greater attention must be paid on the treatment of wastewater, its reclamation and reuse, as this will go a long way to protect our ground water reserves while at the same time relieving our rivers from the burden of water pollution. This paper presents a case study of Nanded city for reuse of wastewater for irrigation. For selecting the best alternative wastewater treatment process on different cost small computer programme is developed in C language. Also for showing the increase in net benefits with wastewater linear programming model is formulated for selected study area.

Abstract: Mankind is facing serious problem of acute water shortage on planet earth. There are various factors, which are responsible for water shortage. Population growth is one of the biggest affecting factors. It affects balance between water availability and its use. Demand of water is increasing day by day but the available water supply is falling short. Therefore it is very necessary to store the available valuable water. The sources of water shall be preserved and protected. River is one of such source of water. Sand in the river has a great potential to hold a lot of water in its course and hence to maintain the ground water table. Sand available in the river bed helps to hold water for longer duration. But, the infrastructure development demands lot of construction material out of which sand is one of the major ingredient. This sand is made available from rivers. If dredging is done excessively it adversely affects the water holding capacity of sand in river. Trench filled with sand is representing the river bed without sand dredging and trench without sand represents the river bed after dredging of sand. The measured amount of water is poured in each trench daily and amount of moisture content in trenches is studied. Such study is carried out on different sand samples. This is studied for days together. River bed sand is also tested at room temperature to see that it hold water in the pore spaces. The results are represented with the help of graph in this paper. The results show that the presence of sand in the river bed holds ample water and helps to maintain ground water table.

Abstract: Groundwater is being exploited at rapid rate to meet the increasing demand. Groundwater occurrence, movement, depends on the geological formations forming the aquifers. The porous media comprising of fissured rocks, sandwiched between impervious hard rock is one group of geological formations found in confined aquifers. Loni, the study area comprises of top overburden soil crest, gravel, and weathered rock leading to fissured rock, which functions as flow media. The annual rainfall of 536 mm is barely sufficient to recharge the ground water sources. Seepage from the Pravara canal is the chief source of recharge. Shallow and deep tube wells, which fetch water invariably during various seasons is the chief source of water, which remain dry or supply meager to good yield with season, and flow in canal. Some of the wells in the area is reported to yield good quantity of water throughout the year and had been a perrineal source during the peak drought of 1972. Basaltic Dyke was observed during investigation. Pump tests are carried out to arrive at the aquifer parameters. The wells found on region of dykes showed a remarkable change in the water bearing characteristics in terms of Transmissivity, Storativity and radius of influence.

Abstract: The hydrology of river channels is of vital interest to engineers, biologist and land managers. The quantity of water that will pass through a given channel is a function of the storm event (precipitation) and the watershed characteristics. Watershed characteristics of a basin represent physical and morphological attributes that are employed in synthesizing its hydrological response. However, the manual measurement of basin parameter is labour intensive and GIS can be very useful computer based decision support tool for the integration of spatial data from different sources and for the analysis, manipulation and display of these data. This powerful tool holds a very large potential in the field of regional and micro level spatial planning particularly in micro watershed planning and management. In this study morphometric analysis of one of the watersheds of Rambaira catchment of Jhelum basin has been carried out using GIS software-ArcView 3.2a the study area covers 14.13 km2 located between Latitude 33? 20`. The drainage network was delineated using remote sensing data geocoded FCC of bands-234 of 1c and 1D (LISS ? + PAN merged) on 1: 50, 000 scale and SOI topomaps were used as reference. It has been observed that watershed depicts positive relation between drainage density and stream frequency as the stream frequency increases with increase in drainage density.
