This study explores a wide, long rectangular channel with a bottom slope, designed to connect lakes. The channel is concrete-lined, ensuring durability, and features a constant water level at one lake while the water level at the other fluctuates. The aim is to plot the delivery curve for the channel based on a set discharge rate. Understanding this delivery curve is essential for water resource management and planning, especially in variable conditions.
