Unidirectional flow in agricultural drainage specifically refers to the scenario where water moves in a single direction along the drainage system. This concept is particularly pertinent when dealing with systems that rely on gravity to facilitate the removal of excess water from agricultural fields, such as parallel drains or ditches. In such a system, the design typically involves a series of drainage tiles or pipes placed in parallel, allowing water to flow continuously and efficiently toward a designated outlet or discharge point.

This streamlined flow direction helps to prevent stagnation of water, improves drainage efficiency, and ultimately enhances crop growth by maintaining optimal soil moisture levels. The focus on having drains aligned in parallel facilitates this unidirectional flow, ensuring that water is directed to where it is needed most for effective irrigation or drainage management.
