Reservoir Outlet Gate Mechanism - Engineering Diagram #3409567 (License: Personal Use)

This black-and-white engineering sketch depicts a gravity-fed reservoir outlet system where water flows from the reservoir through a horizontal conduit into an open channel. A hinged flap gate, actuated by a lever arm, controls discharge, while an earthen mound provides structural support and protection against erosion or tampering. The drawing includes labeled components-“RESERVOIR”, “OUTLET”, and ground layers-for instructional clarity.

Used in civil engineering textbooks, irrigation manuals, or municipal water infrastructure guides to explain basic dam or tank outlet designs; targets students, technicians, and planners seeking foundational knowledge of passive flow control systems.
