This study analyses how the hydraulic performance differs between 13 ponds with hypothetically different layouts. The paper also includes a discussion of short-circuiting, hydraulic efficiency and suitable parameters for measuring hydraulic performance. The ponds were studied by using a 2-D vertically integrated numerical model. Tracer studies were simulated and then evaluated and compared. The results confirm that length-to-width ratio, location of in- and outlets, and subsurface berm have a large impact on pond hydraulic performance. There is also an indication that an island placed in front of the inlet improves the hydraulic performance, and that a curved pond or an island placed near the side does not decrease the performance.

Nyckelord: constructed wetlands, design, tracer, CFD
