“…A number of modeling tools are available for optimizing the selection and siting of LID technologies so as to minimize flood risk, maximize human and ecosystem cobenefits, and stay within capital, maintenance, and operation costs. 90−92 These optimization schemes have several elements in common, including: (1) a spatially explicit (e.g., GIS-based) platform that includes information on the informal and formal drainage for a site and candidate locations for LID technologies; (2) a rainfall-runoff model that routes stormwater through the catchment; (3) an objective function that quantifies hydrologic performance (e.g., relative to stormwater harvest and infiltration targets, see Section 2) and costs of candidate LID configurations; and (4) an algorithm that identifies optimal solutions (e.g., by minimizing one or more objective functions) 51 96 Rainfall/runoff models can also be used to explore how a particular stormwater management strategy might impact receiving water quality. An example is the U.S. Environmental Protection Agency's study of the Illinois River (a multijurisdictional tributary of the Arkansas River in the states of Arkansas and Oklahoma) in which a catchment model based on Hydrologic Simulation Program Fortran (HSPF) was calibrated for nutrients and the output linked to a hydrodynamic and water quality model for Lake Tenkiller.…”

Catchment urbanization perturbs the water and sediment budgets of streams, degrades stream health and function, and causes a constellation of flow, water quality, and ecological symptoms collectively known as the urban stream syndrome. Low-impact development (LID) technologies address the hydrologic symptoms of the urban stream syndrome by mimicking natural flow paths and restoring a natural water balance. Over annual time scales, the volumes of stormwater that should be infiltrated and harvested can be estimated from a catchment-scale water-balance given local climate conditions and preurban land cover. For all but the wettest regions of the world, a much larger volume of stormwater runoff should be harvested than infiltrated to maintain stream hydrology in a preurban state. Efforts to prevent or reverse hydrologic symptoms associated with the urban stream syndrome will therefore require: (1) selecting the right mix of LID technologies that provide regionally tailored ratios of stormwater harvesting and infiltration; (2) integrating these LID technologies into next-generation drainage systems; (3) maximizing potential cobenefits including water supply augmentation, flood protection, improved water quality, and urban amenities; and (4) long-term hydrologic monitoring to evaluate the efficacy of LID interventions.

“…Landschapskenmerken zijn van invloed op de wijze waarop regenwater zich gedraagt nadat het in de stedelijke waterkringloop is opgenomen. In verscheidene verstedelijkte gebieden in de wereld is door toepassing van watermanagementtechnieken voor het benutten van natuurlijke processen al een aanzienlijke vooruitgang geboekt [Backhaus et al, 2011;Dietz, 2007;Petrucci et al, 2013]. Deze worden vaak aangeduid als Low Impact Development (LID), Best Management Practices (BMP), Sustainable Urban Drainage Systems (SUDS) of, in het Frans, Techniques Alternatives.…”

“…However, the quantitative analysis is usually extremely simplistic: it generally consists in determining the critical flow rate at one or several critical points of the sewer system, by calculating the admitted flow from upstream parcels by an inversion of the rational formula (Petrucci et al 2013).…”

“…Urban hydrologic models available today (e.g. the US EPA SWMM model; Rossmann 2004) are able to support design of source control facilities on small scales, but they require significant adaptations in order to study different urbanization scenarios under different stormwater management strategies at a large scale (Petrucci et al 2013, Versini et al 2013. Most local authorities do not have the resources to autonomously develop similar analyses: despite the understanding of source control that hydrologists may have, it is difficult to translate it in practice.…”

Urban stormwater source control policies: why and how?

Stormwater source control is becoming a common strategy for urban stormwater management in many countries. It relies on regulations or other policy instruments compelling or inciting implementation, for each new urban development, of small-scale facilities to locally store and manage stormwater. Local authorities that pioneered source control since the 1980s have already observed that small-scale facilities systematically implemented over a catchment are able to influence its hydrological behaviour. This capability is the main strength of source control, as it allows compensation for the negative effects of urbanization. Yet, it also represents its main risk: if initial decision-making is not sufficiently accurate, source control can produce long-term negative effects. Because of its current spreading, source control will acquire an increasing role as a driver of hydrological changes in urban catchments, and the directions of these changes depend on current policy-making practices. This paper presents an analysis and a critical discussion of the main objectives that policy-makers attribute to stormwater source control. The investigation is based on a sample of French case studies, completed by a literature review for international comparison. It identifies four main objectives, some typical of urban stormwater management and some more innovative: flood reduction, receiving waters protection, sustainable development, costs reduction. The discussion focuses on how current policy-making practices are able to translate these objectives in concrete policy instruments, and on which knowledge and tools could improve this process. It is shown that for some objectives, basic knowledge is available, but the creation of policy instruments which are effective at the catchment scale and adapted to local conditions is still problematic. For other objectives, substantial lacks of knowledge exist, casting doubts on long-term effectiveness of current policy instruments. Research directions are identified to improve source control policies and thus the future hydrologic behaviour of many urban catchments.
