A Marie Curie post-graduate research assistant is required to carry out a
research project in UK at HR Wallingford (near Oxford), a leading
international hydraulics research organisation. The fellowship is offered
for 24 months, starting by December 2003.
The work involves research into sustainable drainage systems (referred to
in UK as SUDS, but internationally more commonly referred to as BMPs). A
detailed description of the work is summarised below. This work package is
one of 13 integrated modules of a major research project led by Imperial
College funded primarily by EPSRC. The integrated research project aim is
to provide guidance and tools for best practice use of water within the
context of Water management for developments, referred to as WaND. The web
site for WaND is available to view at www.wand.uk.net.
Eligibility
Candidates must be from an EU country (excluding UK) or state associated to
the 5th European Research Programme (Bulgaria, Cyprus, Czech Republic,
Estonia, Hungary, Iceland, Israel, Latvia, Liechtenstein, Norway, Poland,
Romania, Slovak Republic or Slovenia) and have completed a degree,
preferably in civil or environmental engineering.
Interested applicants are asked to contact Thierry Rault and/or Richard
Kellagher as soon as possible:

Work package 2: Stormwater Team leader:HR Wallingford
JUSTIFICATION
Over the last decade, a revolution has taken place in surface water
drainage with numerous alternative drainage methods being used mainly to
limit the rate and volume of runoff to greenfield levels, but also to
ameliorate water quality. They are applied in 'trains' throughout the
drainage system, from plot to street to development levels, rather than
just at the final outflow to receiving watercourses. Usually referred to as
Sustainable Drainage Systems (SUDS) in the UK or Best Management Practices
(BMPs) elsewhere in the world, they aim to address some of the hydraulic
and water quality issues relating to pipe systems. Considerable research
has taken place on water quality loads in pipe drainage systems and also
for the range of SUDS components (Mikkelsen, et al., 1997; Jefferies , et
al., 2001). There is an urgent need to utilise the information that exists
to allow systems to be assessed for their water quantity and quality
performance. In addition it is important that the proposed solutions can be
evaluated for a measure of sustainability in the context of that particular
environment.
GOALS
The objectives for this work package are:
· To evaluate the sustainability issues relating to each form of drainage
system type and develop selection criteria by which they can be used in the
appropriate circumstance.
· To develop and validate a suite of models that quantify the hydraulic and
water quality performance characteristics of the main drainage components,
separately and in trains
· To develop detailed design guidance and methods for the water quantity
and quality design of drainage components.
This will feed back into the Toolbox in work package 6 to enable best
practice design and system evaluation to be carried out. The feedback loop
of rainwater re-use will also directly interact with other packages.
DELIVERABLES
For this work package the deliverables will cover both hydraulic and water
quality aspects:
1 selection criteria for appropriate choice of drainage components.
2 performance information for key stormwater drainage components
3 design criteria and computer simulation modules for all stormwater
drainage components
4 design methodologies to enable an integrated approach to drainage and the
related work packages
METHODOLOGY
The project will draw on data, which already exists and is available to HR
Wallingford and others in the group. There are many areas of uncertainty
due to the relatively limited information on certain drainage components,
but the analysis will be based on what is known and available. In outline
the method of approach will be to:
· Collate and summarise the critical features and design constraints of all
drainage components
· Define potential linkages between drainage components and the water
supply/re-cycling systems
· Define the sustainability issues to be evaluated for drainage components
· Define a consistent approach for assessing greenfield runoff rates
· Collate and summarise performance information for drainage system
components
· Develop tools to enable an integrated evaluation of drainage system
components and trains, over the full range of weather conditions expected
during their lifetime
· Develop a method statement for evaluating new developments using a range
of drainage system components
· Derive guidance on sustainability selection of drainage system components
PERSONNEL
The work will be carried out by a Research Assistant based in Wallingford.
The principal supervisors will be Richard Kellagher of HR Wallingford.
