Exploring Uncertainty in Uncalibrated Bioretention Models

2018
Using SWMM 5.0.016, a case study of a street right-of-way bioretention system (ROWB) configured as a storage node is compared against SWMM’s “LID Controls”. Through a series of 1-yr continuous simulations, the uncalibrated models indicate that a storage node representation of a media-filled system substantially underestimates stormwater retention and ...

The role of plant uptake in total phosphorous and total nitrogen removal in vegetated bioretention cells using vetiver and cattail.

Chemosphere
Bioretention cells have emerged as a prominent strategy for mitigating pollutant loads within urban stormwater runoff. This study delves into the role of plant uptake in the simultaneous removal of nitrogen and phosphorus compounds within these systems ...

Migration of naphthalene in a biochar-amended bioretention facility based on HYDRUS-1D analysis.

Journal of Environmental Management
Biochar has been proved as a promising and efficient filler in bioretention facilities for enhancing the stormwater pollutants removal. However, the migration behaviors of stormwater pollutants in biochar filled bioretention facilities is unclear.

Compare individual and combined bioretention systems on the reduction of thermal pollution from stormwater runoff.

Journal of Environmental Management
Urban surface temperatures are high in summertime, and thermal pollution caused by heat transfer from pavement to stormwater runoff is harmful to aquatic ecosystems.

ENGINEERED BIORETENTION FOR REMOVAL OF NITRATE FROM STORMWATER RUNOFF

Proceedings of the Water Environment Federation, 2000
A bioretention unit is a simple, plant‐ and soil‐based, low‐impact treatment and infiltration facility for treating stormwater runoff in developed areas. Nitrate, however, is not attenuated in conventional bioretention facilities. Thus, this study systematically evaluated a reengineered concept of bioretention for nitrate removal via microbial ...

Sulfoaluminate cement-modified loess as bioretention cell filler for nutrient removal from stormwater runoff.

Environmental Research
In order to reduce the consumption of sand and gravel resources, the use of loess can reduce transportation costs and realize the in-situ construction of spongy in areas with rich loess resources. But the collapsibility and low permeability of loess make

Designing Bioretention Areas for Stormwater Management

Environmental Processes, 2016
Governing equations for designing bioretention areas for both flood control and water-quality control are developed, and a design protocol for applying these equations is also presented. Factors taken into account include the flood-control return period, the local intensity-duration-frequency (IDF) function, the catchment volumetric runoff coefficient,

Enhancing bioretention efficiency for pollutant mitigation in stormwater runoff: Exploring ecosystem cycling dynamics amidst temporal variability.

Bioresource Technology
In this study, three distinct bioretention setups incorporating fillers, plants, and earthworms were established to evaluate the operational efficiency under an ecosystem concept across varying time scales.

Preliminary Design Aid for Bioretention Filters

Journal of Hydrologic Engineering, 2013
AbstractA physically based mathematical model is developed in this study for the hydrologic process taking place in a bioretention filter. The hydrologic storage equation is adopted to determine the variation of water depth in the ponding area. The Green and Ampt equations are used to model the movement of water in the underlying storage zone, or soil ...
