Assessment and Analysis of Maximum Precipitation at Bharkawada Village, Palan...RSIS International
Efficient Storm water network is the main tool to prevent the water gatheration and scattering of a city. Selecting the Bharkawada as study area and its problem was identified to be of very less effective drainage system. In this study methods have been adopted to identify the possibilities of completing the research for designing the storm water drainage design. Our main aim is to design a very efficient and rpid drainage system which should drain the water very fastly with less concentration time and less spreading of water with less provision of slope. The present design is based on rainfall data. Past 30 years rainfall data has been taken for study. The system has been designed considering in total of 65% of the impervious area. Estimated rainfall intensity has been calculated as 33.02527 mm/hour with a recurrence interval of 2 years from the detailed analysis of rainfall data of 34 years. Rainfall Intensity is estimated after frequency analysis of the rainfall data. The calculated runoff is 25.056 m3/s, which can be used as a design discharge for network designing. Different methods can be used for runoff estimation. Here, Rational method seems to be best for use in estimation of storm water runoff. The outfalls of system are directed to proposed lakes. Ere at this stage rainfall calculations have been done and in future work complete rainfall and runoff analysis will be carried out for storm water network.

NUMERICAL MODELLING OF BRINE DISPERSION IN SHALLOW COASTAL WATERSIAEME Publication
Fresh water is a limited finite resource, vital for the existence of every life on earth. It is becoming a scarce commodity. This is due to population growth, climatic changes with more frequent extreme events such as droughts and floods, increased water contamination of existing supplies, inefficient use of water etc. To overcome this scarcity, creation of fresh water from sea water by the process of desalination is a effective and reliable way. Hence desalination plants are being widely used in coastal areas.
This study evaluates the performance of green infrastructure (GI) techniques like bioswales and infiltration basins in improving stormwater quality, compared to traditional detention basins. Two adjacent sub-watersheds using these different approaches in a master-planned community are monitored. Preliminary results show the bioswale watershed significantly outperforming the detention basin watershed in removing pollutants like suspended solids, nitrogen, phosphorus, heavy metals, and copper in particular.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
