Step 1: Understand types of waterway crossings. When two waterways intersect, different structures are used depending on their relative levels: Aqueduct: One waterway passes over another. Syphon: Water flows under an obstacle through a closed conduit. Level Crossing: Both waterways meet and cross at the same elevation. Inlet and Outlet: Points where water enters or exits a system. Step 2: Match definition with question. Since the canal and drainage meet at the same level, the correct term is: $$ \boxed{\text{Level Crossing}} $$ Step 3: Eliminate incorrect options. Aqueduct: Used when one waterway is above another. Syphon: For crossing under obstacles. Inlet and Outlet: Not a structural crossing.
