Detention pond vs retention pond.

Learn the differences between detention and retention ponds, two types of ponds that are commonly used to control storm water and floods after heavy rains. Find out their purposes, advantages, requirements, limitations, costs, and pros and cons for different climates and topographies. In order to reduce the flooding risk in urban and peri-urban river catchments, retention ponds or wet detention ponds are often used. However, there has been little work that uses distributed hydrological modeling to consider their optimum location and design in order to reduce the flood risk in a river catchment. This work considers two …A detention pond is a dry pool but quickly fills during rainfall. These ponds temporarily hold the excess water and then slowly release it to another location.

In retention ponds, hydraulic, hydrologic, and botanic designs are integrated and interconnected for long-term sustainable outcomes (Wong, 2006). The compartmentalization of stormwater retention ponds operates the by-pass high flows to the detention storages within the required detention time and inter-event periods.

Detention vs. Retention. A retention tank usually refers to a tank that is meant to be filled with stormwater so that it can be used for a different purpose at a later time. Detention tanks, on the other hand, are used to meter the flow of stormwater back into the soil or additional drainage systems which eventually lead back to a local sewer. Nov 26, 2021 · A retention pond collects stormwater during a storm and slowly releases it back into the natural environment. Therefore, it should be built on a slope that directs water into the pond to achieve this goal.

They are often called dry ponds and benefit subdivisions when the land available for construction has an appealing slope. Also, most frequently are used to satisfy city ordinances that require a subdivision to ...The difference in the maximum and retention elevations in the pond is the detention volume. With this method, the detention volume is stacked on the retention volume. Both wet and dry ponds can be configured in this way.
