Using nature's design to stem urban storm-water problems

Urban Storm Water Pollution Forecasting Using Recurrent Neural Networks 1

To reduce the impact of stormwater pollution on the environment, operators in charge of urban drainage systems and waste water treatment plants need real-time predictions of pollutant concentrations during rainfall events. In this paper, this problem is addressed using nonlinear recurrent neural networks, which are used to simulate the rainfall-runo transformation, as well as the production and...

Storm water runoff concentration matrix for urban areas.

The infrastructure (roads, sidewalk, commercial and residential structures) added during the land development and urbanisation process is designed to collect precipitation and convey it out of the watershed, typically in existing surface water channels, such as streams and rivers. The quality of surface water, seepage water and ground water is influenced by pollutants that collect on impervious...

Modeling Urban Storm-Water Quality Treatment: Model Development and Application to a Surface Sand Filter

A mathematical and statistical model for simulating contaminant removal from a surface sand filter is reported. The model was based on a mass balance equation and an advection-dispersion transport model. The unknown parameters of the model were the deposition rate and the hydrodynamic dispersion. Changes in space were allowed within the filter media depth and time variability of flow and influe...

Off-stream Detention Design for Storm Water Management

A detention basin is designed for storm water quantity and quality controls. An in-stream basin is often located on a widened floodplain, while an off-stream basin can be part of open space in a parking lot, park, or sport field. The inflow channel associated with an off-stream basin is allowed to carry its base flow not to exceed the downstream capacity. When the inflow channel is full, the ex...
