IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

A field approach for comparing the ecosystem services from suds and non-suds

ABSTRACT
Sustainable Urban Drainage systems (SUDS) are engineering solutions with the intention to mimic natural systems. SUDS
were introduced to Scotland in the early 1990s with the establishment of the Forth Purification Board, latterly known as
SEPA, in 1994. Their design is based on the SUDS triangle which incorporates water quality, water quantity, and amenity
drivers. Until recently, the main focus was diffuse pollution and how SUDS offered a unique opportunity for pollutant
removal from urban and peri-urban water courses. Climate change has increased the awareness for SUDS in terms of the
benefits for pluvial flood risk management. Very little, however, has been done to quantify the benefits from SUDS in terms
of the three main pillars of sustainability: social, economic and environmental factors. The often overlooked component of
the SUDS triangle is the amenity component, especially with respect to habitat. It is therefore the focus of this paper to
make the connection between aquatic habitats (ponds and wetlands) and the amenity and biodiversity functions offered.
Habitat is fundamentally important to SUDS and assessment of Ecosystem Services. Ecosystem Services refer to the end
user benefits obtained from the environment. Very few studies, to date, assess the Ecosystem Services from SUDSalthough
attempts have been made from the social science studies in terms of conceptualising SUDS and Ecosystem
Services (Lundy and Wade, 2011; Scholz and Uzomah, 2013) none have assigned a monetary value to these services.
The main focus of this paper, therefore, is to highlight the importance of Ecosystem Services as part of the valuing
process in SUDS. It will align well established techniques in hydro-ecology with monetary valuation using Contingent
Valuation Methods (CVM). Methods and some preliminary results will be presented, as well as the key lessons discovered
during the experimental and field season phases. It is hoped that the study will allow for inter site comparisons to inform
the environmental management and planning decisions- as well as providing a benchmark for future studies.
