“…In order to meet flood control requirements, and therefore be more widely adapted, the effect of LID during extreme events must be considered. Several studies used SWMM to model LID practices prior to the addition of explicit LID controls within the model (Huber et al ., ; Khader and Montalto, ; Abi Aad et al ., ; Damodaram et al ., ; Eichenwald and McGarity, ). Rossman () described simulating LID controls using the latest version of SWMM.…”

The Storm Water Management Model was used to simulate runoff and nutrient export from a low impact development (LID) watershed and a watershed using traditional runoff controls. Predictions were compared to observed values. Uncalibrated simulations underpredicted weekly runoff volume and average peak flow rates from the multiple subcatchment LID watershed by over 80%; the single subcatchment traditional watershed had better predictions. Saturated hydraulic conductivity, Manning's n for swales, and initial soil moisture deficit were sensitive parameters. After calibration, prediction of total weekly runoff volume for the LID and traditional watersheds improved to within 12 and 5% of observed values, respectively. For the validation period, predicted total weekly runoff volumes for the LID and traditional watersheds were within 6 and 2% of observed values, respectively. Water quality simulation was less successful, Nash-Sutcliffe coefficients >0.5 for both calibration and validation periods were only achieved for prediction of total nitrogen export from the LID watershed. Simulation of a 100-year, 24-h storm resulted in a runoff coefficient of 0.46 for the LID watershed and 0.59 for the traditional watershed. Results suggest either calibration is needed to improve predictions for LID watersheds or expanded look-up tables for Green-Ampt infiltration parameter values that account for compaction of urban soil and antecedent conditions are needed.

This review on Sustainability covers selected journal articles and conferences papers published in 2010 and is divided into the following sections  • Sustainable water and wastewater utilities:  • Sustainable water resources management  • Industrial and corporate approaches towards sustainability  • Stormwater and green infrastructure  • Sustainability in wastewater treatment  • Life cycle assessment (LCA) applications  • Sustainability and energy in wastewater industry  • Sustainability and climate change  • Sustainability and water reuse  • Sustainability rating systems  The sustainable water and wastewater utilities reviewed sustainable practices and sustainable workforce management. The stormwater and green infrastructure (GI) described the current development in five categories: new studies of GI and low impact development (LID) system performance; GI/LID system planning assessments; macro‐scale hydrologic and hydraulic modeling of GI/LID systems; efforts to model changes of water flow and quality in individual GI/LID systems; and social implications of GI/LID systems. The sustainability in wastewater treatment reviewed wastewater treatment; source separation; anaerobic technologies; wetland and low impact treatment systems; algae technologies; and the microbial fuel cell technology.
