detention time optimization

Improving the performance of stormwater detention

Dry detention ponds are commonly implemented to mitigate the impacts of urban runoff on receiving water bodies. They currently rely on static control through a fixed limitation of their maximum outflow rate. Real-Time Control (RTC) allows optimizing their Get price

Water

The optimization of the efficiency of detention basins has been discussed for several decades. In most literature, the size and location of detention basins have been determined to minimize flood damage using different algorithms, such as nonlinear programming [], dynamic programing [6,7,8,9], and meta-heuristics algorithms such as the genetic algorithm [], simulated annealing [], the Get price

Research on the Optimization Design of Abnormal Flip

The calculation time step mainly serves to assist in optimization, its main function being the division of time periods. Time will also influence the pressure and the velocity at falling points. Using a single time point makes it difficult to prove that the results are optimal; therefore, one time period was chosen. Get price

Detention Basin Retrofit: Optimization of Water Quality

A detention time comparison between the current NJDEP water quality storm and the 1-year, 24-hour storm is presented as well. 4 As indicated in bold within Tables 1-A, 2-A, and 3-A, for each weir elevation, a single peak outflow is obtained which represents the largest increase in total peak outflow for any design storm for each weir elevation.

Optimal design of stormwater detention basin using the

N2 - The urbanization of an undeveloped area often shortens outflow travel time and increases peak discharge from the basin, thereby increasing the downstream flood frequency. Stormwater detention ponds are the most common measure to maintain the outflow from the post-developed basin to a flow similar to that under the pre-developed condition. Get price

The Newest Rule on Demurrages and Detention Will Likely

2020/6/5Consequently, many shippers and intermediaries began sharing their discontentment with the FMC regarding carrier and MTOs' free time, demurrage, and detention practices. In 2015, the FMC responded to the complaints with a relatively short study and report on the complicated topic, but the resulting study did not have much impact on industry sentiment or changing demurrage and detention Get price

Wastewater Clarifier Performance

Detention time in the clarifier needs to be in the range of 2.0 to 3.0 hours. Too short a detention time will cause solids carryover and too long a detention time will increase septicity. In my experience 3 hours of detention is too much and will likely increase septicity in the sludge during warmer months. Get price
