“…Numerous studies across a wide range of geographic locations and climates show that urbanization can alter catchment hydrologic responses and negatively impact surface and downstream waters (for example: Athayde et al, 1983;EPA, 1997;Maestre and Pitt, 2006;Shuster et al, 2005;Smullen et al, 1999;Walsh et al, 2005a;Wenger et al, 2009;Zampella et al, 2007). Early urban runoff monitoring efforts such as Nation Wide Urban Runoff Program (NURP, Smullen et al, 1999), the National Water Quality Assessment Program (NAWQA, Brown et al, 2009) and the National Stormwater Quality database (NSQD, Maestre and Pitt, 2006;Pitt et al, 2008) aimed to identify urban runoff responses from distinct urban land uses.…”

However, the data showed mixed responses to land use, indicating more complex controls on urban runoff responses.…”

cover controls on summer discharge and runoff solution chemistry of semi-arid urban catchments" (2013 Recharge of urban runoff to groundwater as a stormwater management practice has gained importance in semi-arid regions where water resources are scarce and urban centers are growing. Despite this trend, the importance of land cover in controlling semi-arid catchment runoff quantity and quality remains unclear. Here we address the question: How do land cover characteristics control the amount and quality of storm runoff in semi-arid urban catchments? We monitored summertime runoff quantity and quality from five catchments dominated by distinct urban land uses: low, medium, and high density residential, mixed use, and commercial. Increasing urban land cover increased runoff duration and the likelihood that a rainfall event would result in runoff, but did not increase the time to peak discharge of episodic runoff. The effect of urban land cover on hydrologic responses was tightly coupled to the magnitude of rainfall. At distinct rainfall thresholds, roads, percent impervious cover and the stormwater drainage network controlled runoff frequency, runoff depth and runoff ratios. Contrary to initial expectations, runoff quality did not vary in repose to impervious cover or land use. We identified four major mechanisms controlling runoff quality: (1) variable solute sourcing due to land use heterogeneity and above ground catchment connectivity; (2) the spatial extent of pervious and biogeochemically active areas; (3) the efficiency of overland flow and runoff mobilization; and (4) solute flushing and dilution. Our study highlights the importance of the stormwater drainage systems characteristics in controlling urban runoff quantity and quality; and suggests that enhanced wetting and in-stream processes may control solute sourcing and retention. Finally, we suggest that the characteristics of the stormwater drainage system should be integrated into stormwater management approaches.

“…Maestre and Pitt (2006) analyzed significant factors ( e.g., The EPA rain zone, percentage of imperviousness, land use, type of conveyance, controls in the watershed, sample analysis method, and type of sampling procedures) affecting stormwater quality using the National Stormwater Quality Database. It was observed that TSS, TP and Cu concentration in stormwater runoff was higher in summer and fall than in winter and spring.…”

“…Although notable progress was made in the modeling of urban runoff quantity, the progress with stormwater quality-its impacts on receiving waters and the means of mitigating such impacts-has been much slower (Marsalek & Viklander, 2011). Example of recent research includes identification of significant factors (e.g., land use, percentage imperviousness, conveyance, and watershed controls) affecting stormwater quality using the National Stormwater Quality Database (Maestre & Pitt, 2006), highway contribution to runoff quantity and pollutant loading (Lau et al, 2009), sampling issues in urban runoff monitoring programs by comparison of composite and grab samples (Ma et al, 2009), and groundwater contaminations by stormwater (Pitt et al, 1996;Foulquier, 2010).…”

The study analyzed hydro-climatic and land use sensitivities of stormwater runoff and quality in the complex coastal urban watershed of Miami River Basin, Florida by developing a Storm Water Management Model (EPA SWMM 5). Regression-based empirical models were also developed to explain stream water quality in relation to internal (land uses and hydrology) and external (upstream contribution, seawater) sources and drivers in six highly urbanized canal basins of Southeast Florida. Stormwater runoff and quality were most sensitive to rainfall, imperviousness, and conversion of open lands/parks to residential, commercial and industrial areas. In-stream dissolved oxygen and total phosphorus in the watersheds were dictated by internal stressors while external stressors were dominant for total nitrogen and specific conductance. The research findings and tools will be useful for proactive monitoring and management of storm runoff and urban stream water quality under the changing climate and environment in South Florida and around the world.
