Measurement and three-dimensional simulation of flow in a rectangular detention tank

• There are two main ways to obtain better knowledge of the hydraulics of ponds, namelymeasurements and simulations. In this study, the applicability of using three-dimensionalsimulations as an engineering tool in stormwater pond design was investigated. To dothis, three-dimensional simulations were compared with measurements of flow patternand residence time in a large physical model of a detention tank (13 x 9x 1 m). Theagreement between measurements and simulations concerning both flow pattern andresidence time distribution curves was found to be good for high flow rates.
