  What are the different types of dams? Arch  Dam. A concrete or  masonry  dam, which is curved upstream so as to transmit the major part of the water load to the abutments. ... Buttress Dam. ... Coffer Dam. ... Diversion Dam. ... Embankment Dam. ... Gravity Dam. ... Hydropower  Dam. ... Industrial Waste Dam. Which is the biggest dam of world? Three Gorges Dam Three Gorges Dam , China is the world's largest hydroelectric facility. In 2012,  the Three Gorges Dam  in China took over the #1 spot of the largest hydroelectric dam (in electricity production), replacing the Itaipú hydroelectric power plant in Brazil and Paraguay.

                                                                     Hydraulic jump practical part-1 Loss of Kinetic Energy. The velocity of subcritical flow is less than supercritical flow. The depth of subcritical flow is greater than the depth of supercritical flow. Calculation part For discharge= Q= volume/time Q= A * V Q= b * Y1 * V1 Q= b * Y2 * V2 Fr1 = V/ root ( g*y1) loss of enenrgy= (y2-y1)^3 ------------- 4y1*y2 A hydraulic jump is a phenomenon in the science of hydraulics that is frequently observed in open channel flow such as rivers and spillways. When liquid at high velocity discharges into a zone of lower velocity, a rather abrupt rise occurs in the liquid surface. Types of Hydraulic Jumps – Based...
