Bhatsa Dam is one of the largest gravity dams in Maharashtra. Construction began in 1977 and was completed in 1983. It was built with unreinforced concrete masonry and has 5 radial gates measuring 12m x 8m. The dam provides irrigation to 23,000 hectares of land via its left and right bank canals. It also generates hydroelectric power through a power station located 6km downstream, and supplies this power to the local electricity grid. The dam serves multiple purposes, including water supply, flood control, irrigation, power generation, and development of fisheries in the region.
Coastal Research Vessel
This document compares different vessel designs for use as oceanographic research vessels, including monohulls, catamarans, and small waterplane area twin hull (SWATH) vessels. Monohulls have less resistance at lower speeds but higher resistance at higher speeds compared to catamarans. Catamarans have better maneuverability due to dual propulsion but can experience stresses between hulls in rough seas. SWATH vessels combine features of catamarans and semi-submersibles, retaining a large deck area while placing displacement below waves for improved motion control and reduced drag. Design considerations and specifications for the research vessel R/V Kilo Moana, a SWATH ship, are provided.

The document describes a new hull design called SLICE that allows small ships to operate at high speeds in rough seas. SLICE builds on previous SWATH (Small Waterplane Area Twin Hull) designs by further reducing the waterplane area and shortening the hull length. This allows SLICE vessels to maintain high speeds in larger waves compared to conventional monohulls or catamarans. Testing of a SLICE prototype demonstrated its ability to operate at over 30 knots while producing very low wake wash, using 20-35% less power than comparable designs. The document outlines potential military and commercial applications for SLICE ships.
A comparative study on river hydrokinetic turbines blade profiles
Diesel based electricity supply is the common practice in rural and isolated areas in the North of Brazil. The diesel fuel is usually transported from a nearby city as Manaus by river to these isolated communities. During wet seasons and inundations this means of transport is very risky and not usually safe. The hydrokinetic technology is among the promising technologies for most of the Amazon areas because of the large hydraulic capacity and low density population settlements. In this paper the authors propose a cheap hydrokinetic turbine system whose blades are easy to design, manufacture, replace when necessary and its operation is independent of flow direction. In this work CFD, RANS (Reynolds Average Navier Stokes) equations are used to characterize and develop a methodology of numerical simulation of a vertical axis hydrokinetic turbine. In the simulations, four blade profiles were investigated. The effects of the number of blades, blade profile and water flow velocity on the turbine torque and power coefficients were presented and discussed.
