The Glasgow sustainable urban drainage system management project: Case studies (Belvidere hospital and Celtic FC stadium areas)
The Glasgow Sustainable Urban Drainage System (SUDS) Management Project satisfies the first phase
of the Glasgow Surface Water Management Project. This is Glasgow City Council’s contribution to the
Transformation of Rural and Urban Spatial Structure (TRUST) project, one of the European Union’s (EU)
interregional (INTERREG IIIB) funded research projects. The remit of this EU project comprises also
other representative regions in Europe. The project shows also how SUDS can contribute to the overall
catchment dynamics of cities such as Glasgow, ultimately relieving stress on the current predominantly
combined sewer system. Fifty-seven sites within 46 areas of Glasgow were identified for investigation. A
detailed soil chemistry analysis, a preliminary SUDS feasibility assessment and a desk study relating to
historical planning issues that may be relevant for subsequent future development and regeneration options
were undertaken. Detailed design and management guidelines were then drafted for selected representative
demonstration areas (Belvidere Hospital and Celtic FC Stadium Areas) of high public and property
developers interest, and education value. A combination of infiltration trenches or swales with ponds
or underground storage were the most likely SUDS options for the majority of the demonstration areas.
Soil contamination issues were considered when selecting SUDS because heavy metals such as lead and
zinc can cause environmental health problems

Design comparison of experimental storm water detention systems treating concentrated road runoff
The aim was to assess the treatment efficiencies of experimental storm water detention (extended
storage) systems based on the Atlantis Water Management Limited detention cells receiving concentrated
runoff that has been primary treated by filtration with different inert aggregates. Randomly collected gully
pot liquor was used in stead of road runoff. To test for a 'worst case scenario', the experimental system
received higher volumes and pollutant concentrations in comparison to real detention systems under real
(frequently longer but diluted) runoff events. Gravel (6 and 20 mm), sand (1.5 mm), Ecosoil (inert 2 mm
aggregate provided by Atlantis Water Management Limited), block paving and turf were tested in terms of
their influence on the water quality. Concentrations of five-day @ 20� C ATU biochemical oxygen demand
(BOD) in contrast to suspended solids (SS) were frequently reduced to below international secondary
wastewater treatment standards. The denitrification process was not completed. This resulted in higher
outflow than inflow nitrate-nitrogen concentrations. An analysis of variance indicated that some systems
were similar in terms of most of their treatment performance variables including BOD and SS. It follows that
there is no advantage in using additional aggregates with high adsorption capacities in the primary treatment
stage
A Deterministic Polynomial--Time Algorithm for Constructing a Multicast Coding Scheme for Linear Deterministic Relay Networks
We propose a new way to construct a multicast coding scheme for linear
deterministic relay networks. Our construction can be regarded as a
generalization of the well-known multicast network coding scheme of Jaggi et
al. to linear deterministic relay networks and is based on the notion of flow
for a unicast session that was introduced by the authors in earlier work. We
present randomized and deterministic polynomial--time versions of our algorithm
and show that for a network with destinations, our deterministic algorithm
can achieve the capacity in uses of the
network.Comment: 12 pages, 2 figures, submitted to CISS 201
A new iterative method for generalized equilibrium and constrained convex minimization problems
The gradient-projection algorithm (GPA) plays an important role in solving constrained convex minimization problems. In this paper, we combine the GPA and averaged mapping approach to propose an explicit composite iterative scheme for finding a common solution of a generalized equilibrium problem and a constrained convex minimization problem. Then, we prove a strong convergence theorem which improves and extends some recent results
