When a wave strikes a vertical breakwater in deep water, it is reflected back and on meeting another advancing wave of similar amplitude merges and rises vertically in a wall of water. This phenomenon is called By increasing the rise of lock-gates, (i) The length of the lock gate will increase (ii) Transverse stress due to water pressure on the gate will increase (iii) Compressive force on the gate will increase If the depth of an excavation is 20 meters, number of single stage well points to be installed at various levels, is A sewer that receives the discharge of a number of house sewers is called If two forces each equal to 'T' in magnitude act at right angles, their effect may be neutralized by a third force acting along their bisector in opposite direction whose magnitude will be
