“…For example, studies in urban watersheds have documented increased streamflow, reduced time of concentration [Wissmar et al, 2004;Murdock et al, 2004], altered soil moisture levels [Carlson and Arthur, 2000;Arthur-Hartranft et al, 2003], increased runoff losses [Corbet et al, 1997], and reduced albedo [Schmid et al, 1991]. Furthermore, urban areas can alter the transport of nutrients and other contaminants to surface water bodies [Interlandi and Crockett, 2003], which result in increased primary productivity [Smart et al, 1981] and impaired water quality. There have been many studies assessing the impact of agricultural activity on non\point contaminant sources [Puckett, 1995;Ekholm et al, 2000;Sharpley et al, 2001;Andraski and Bundy, 2003], but relatively few comprehensive studies characterizing the effects of urbanization on watershed scale hydraulic response and water quality [Rodriguez et al, 2003;Carle et al, 2005].…”

[1] Effective control of nonpoint source contaminants in runoff from urbanized watersheds requires knowledge about the locations of runoff source areas under a variety of conditions. Physical monitoring of spatially variant processes, such as runoff production form variable source areas, is time-consuming and expensive. Thus modeling the processes may provide a valuable cost-effective alternative. In this paper we adapt and validate a variable source model for an urban watershed to predict areas of the landscape prone to elevated soil moisture levels and saturation excess runoff. We modified the soil moisture distribution and routing (SMDR) model to simulate hydrologic processes in an urban upstate New York watershed by considering the impact of impervious surfaces, hydraulic control structures (detention basins), and land use on the water balance. In our model, infiltration excess runoff from impervious surfaces infiltrates in the surrounding soils. Simulated and observed streamflow agreed well, and more importantly, the distribution of soil moisture levels and overland flow throughout the watershed were well predicted. Removing urban features from the model resulted in substantially lower peak stormflows than observed, and the base and interflows increased accordingly. Both modeled and measured distributed results indicated that the more urbanized areas of the study site had both higher soil moistures and runoff losses due to shallower soils, greater upslope contributing areas, and a larger area of impervious surfaces generating runoff. The model results helped identify processes that describe how urbanization impacts integrated and distributed hydrology, which provides useful information for targeted water quality management.

“…Rising chloride concentrations in lakes and streams have been linked to chloride use on land (O'Connor and Mueller 1970, Lathrop 1988, Rosenberry et al 1999, Interlandi and Crockett 2003. Although chloride is most frequently associated with roadway deicing chemicals, chloride is also a component of fertilizers and animal feeds and is used in residential water softening (Herlihy et al 1998, Bates 2000, Smart et al 2001, Thunqvist 2004.…”

“…The common methods of efficiency assessment include ratio analysis, regression analysis, and DEA [69]. One characteristic of DEA is that no prior knowledge of the production function between the input and output attribute data is required; similarly, no relative weight needs to be set for the attribute data [54,[60][61][62][63][64][65][66][67][68][69][70][71][72]. Therefore, DEA is useful for comprehensively assessing the indicators of different types and data patterns; it is widely used in economic science, agricultural economics, public economics, financial economics, and economic policy.…”

This study describes a new assessment model framework, termed the driving forces-pressure-state-impact-policy and pattern (DPSIP) model, for environmental change efficiency in urban land development, based on urban sustainable development and the theory of economic efficiency evaluation. A spatial and measurable efficiency value is defined for environmental changes in urban land development, which provides a comprehensive evaluation index for the efficiency of urban development and its environmental impact. This type of urban interior sustainability is considered new within the context of global environmental changes. We identify nine important indicators to evaluate the relative efficiency of 233 neighborhoods in Tainan, Taiwan. The results indicate that the average environmental change efficiency is 89.44%, which shows clear spatial differentiation. The key indicators affecting the efficiency score are area, population density, location, mixed land uses, the floor area ratio, and the impervious ratio. In the future, urban design can reduce environmental impacts and enhance efficiency values.
