MODEL SIMULATION OF DRY STORMWATER DETENTION POND WITH IPCC AR6 PROJECTED CLIMATE CHANGE SCENARIOS

Dry detention ponds are good practices for stormwater management that control flow discharge by temporarily storing water and gradually releasing it with no permanent water ponding. A real-life dry stormwater detention pond in Sarawak, Malaysia, was selected for this study. The pond has a dimension...

A real-life dry stormwater detention pond in Sarawak, Malaysia, was selected for this study. The pond has a dimension of 80 (length) × 10 (top width) × 1.98 (depth) m3. The inlet is the end of a drain extended from a local government complex with a 27,800-m2 catchment area, and the outlet is an orifice with a 0.45-m diameter.

The expected rise of the pond’s water levels to the extent of overflowing was ruled out. Instead, water levels were maintained below the pond-full level due to the orifice.

description Dry detention ponds are good practices for stormwater management that control flow discharge by temporarily storing water and gradually releasing it with no permanent water ponding. A real-life dry stormwater detention pond in Sarawak, Malaysia, was selected for this study. The pond has a dimension of 80 (length) × 10 (top width) × 1.98 (depth) m3. The inlet is the end of a drain extended from a local government complex with a 27,800-m2 catchment area, and the outlet is an orifice with a 0.45-m diameter. The pond is characterized by a storage volume of 1,050 m3 based on a 30-min, 100-year average recurrent interval design storm. Another characteristic of the pond is the flow restriction imposed by the orifice outlet, in which water levels are always higher behind the orifice.
