Why Single-Event Hydrology Doesn't Work for LID (Stormcon 2009)

Permeable Pavements Modeling

|
Bioretention Modeling
|

|
|
|
|
|
|
Continuous simulation hydrology explicitly represents hydrologic processes such as interception storage, soil moisture fluctuations, evaporation, transpiration, and the effects of long-term infiltration rather than having to make the assumptions used in single-event hydrology.
|
|
|
|
|
|
Permeable pavement works best for flow control when there is infiltration to the native soil. Underdrain flows must still be mitigated to flow control standards. Permeable pavement can reduce stormwater runoff volume, but additional mitigation may still be required to meet Ecology’s flow control standards.
|
|
|
|
|
|
Bioretention works best for flow control when there is sufficient native soil infiltration. Underdrain flows must still be mitigated to flow control standards. Bioretention can reduce stormwater runoff volume, but additional mitigation will still be required to meet Ecology’s flow control standards.

BAHM includes the following LID options: 1) Dispersion of impervious surface runoff on adjacent pervious surface (example: roof runoff to lawn) 2) Infiltration of impervious surface runoff on adjacent pervious surface (soil dependent) 3) Bioretention/rain gardens/landscape swales to retain and infiltrate stormwater

Modeling LID Practices. LIDs reduce stormwater runoff and its associated problems. WWHM is a powerful, easy-to-use storm-water modeling platform adaptable to any region of the country that can be used to model LIDs and help inform and persuade the public and policy makers of the benefits of using LIDs.

BAHM will facilitate compliance with HMP and design of flow control facilities in the Bay Area by providing: 1) An easier, standardized way to do continuous simulation modeling 2) A means to compute flow control benefits of site design/LID and treatment measures 3) Standardized reporting to assist municipal staff in design review

Eco-roofs and bioretention swales reduce stormwater runoff and its associated problems. WWHM is a powerful stormwater modeling tool to help inform and persuade the public and policy makers of the benefits of using low impact development BMPs.
