“…Techniques are emerging that represent the spatial distribution of ecosystem services by normalising each benefit value to a common scale and aggregating these spatially in a geographic information system (GIS) platform (Dobbs et al, 2014;Lauf et al, 2014;Turner et al, 2014). Jayasooriya and Ng (2014) reviewed 20 modelling tools for managing urban flooding and the economics of GI practices and noted the trend for recent tools to include a GIS interface, calling for more tools to incorporate the range of ecosystem services and social benefits that GI practices can provide. Demuzere et al (2014) recognised the trade-offs in which a positive impact of adopting GI-based flood measures can compromise other functions, such as generating larger carbon footprints due to more frequent maintenance activities, or green areas fostering pest and nuisance species with potential associated risks to human health.…”

Traditional approaches to understanding the multiple benefits of sustainable drainage systems often rely on value transfer. This converts each benefit into a monetary value, which can then be compared with the cost of the project. The approach, while well-developed, is limited because it does not systematically incorporate the spatial nature of the benefits. This paper discusses the development of an alternative way of evaluating and comparing benefits, allowing spatial distribution and local context and circumstances to be taken into consideration. The suggested approach is to create a score for each benefit category, which is normalised against a defined initial condition state on a scale of 0 to 10. This approach allows a direct comparison of the relative magnitude of benefits for a given location and provides a clear understanding of how and to whom multiple benefits accrue. The approach allows a singular significant benefit to be compared against many minor benefits. It can also easily be modified to reflect local preferences by weighting each benefit category appropriately. The method is demonstrated by three case studies in Newcastle, UK.

Spatial Evaluation of Multiple Benefits to Encourage Multi-Functional Design of Sustainable Drainage in Blue-Green Cities

Urban drainage systems that incorporate elements of green infrastructure (SuDS/GI) are central features in Blue-Green and Sponge Cities. Such approaches provide effective control of stormwater management whilst generating a range of other benefits. However these benefits often occur coincidentally and are not developed or maximised in the original design. Of all the benefits that may accrue, the relevant dominant benefits relating to specific locations and socio-environmental circumstances need to be established, so that flood management functions can be co-designed with these wider benefits to ensure both are achieved during system operation. The paper reviews a number of tools which can evaluate the multiple benefits of SuDS/GI interventions in a variety of ways and introduces new concepts of benefit intensity and benefit profile. Examples of how these concepts can be applied is provided in a case study of proposed SuDS/GI assets in the central area of Newcastle; UK. Ways in which SuDS/GI features can be actively extended to develop desired relevant dominant benefits are discussed; e.g., by (i) careful consideration of tree and vegetation planting to trap air pollution; (ii) extending linear SuDS systems such as swales to enhance urban connectivity of green space; and (iii) managing green roofs for the effective attenuation of noise or carbon sequestration. The paper concludes that more pro-active development of multiple benefits is possible through careful co-design to achieve the full extent of urban enhancement SuDS/GI schemes can offer.

“…Such tools are often mathematical models of drainage systems where the engineer can set up different designs, simulate performance under different rainfall scenarios, and work towards a solution that optimizes the relevant goals, such as frequency of sewer surcharge, frequency of sewer overflows, etc. Reviews of simulation models used for designing and studying SCM systems can be found in [28,29], while reviews of a wider range of tools supporting choice of SCMs, including utility values such as minimizing greenhouse gas emissions and regulating microclimate, can be found in, e.g., [30].…”

Characteristic Rain Events: A Methodology for Improving the Amenity Value of Stormwater Control Measures

et al. 2017

Local management of rainwater using stormwater control measures (SCMs) is gaining increased attention as a sustainable alternative and supplement to traditional sewer systems. Besides offering added utility values, many SCMs also offer a great potential for added amenity values. One way of achieving amenity value is to stage the rainwater and thus bring it to the attention of the public. We present here a methodology for creating a selection of rain events that can help bridge between engineering and landscape architecture when dealing with staging of rainwater. The methodology uses quantitative and statistical methods to select Characteristic Rain Events (CREs) for a range of frequent return periods: weekly, bi-weekly, monthly, bi-monthly, and a single rarer event occurring only every 1-10 years. The methodology for selecting CREs is flexible and can be adjusted to any climatic settings; here we show its use for Danish conditions. We illustrate with a case study how CREs can be used in combination with a simple hydrological model to visualize where, how deep and for how long water is visible in a landscape designed to manage rainwater.
