  • Pollution profiling and particle size distribution within permeable paving units – with and without a geotextile 

    Mullaney, Jennifer; Rikalainen, Päivi; Jefferies, Christopher (Emerald, 2012)
    The aim of this paper is to investigate the sediment and pollution profiling and particle size distribution with depth within permeable paving structures, both with and without a geotextile. Test rigs set up in an earlier ...
  • Pollutional aspects of gross solids and their interaction with sewer sediments 

    Milne, David A.; Jefferies, Christopher; Ashley, Richard M. (IWA Publishing, 1996)
    This paper describes a study programme underway in the upper Perth Road catchment in Dundee to estimate the effect of gross solids and their interaction with the sediment found within a combined sewer network. Gross solids ...
  • Portable sewage flow sensors: their calibration and accuracy 

    Watt, I. A.; Jefferies, Christopher (IWA Publishing, 1996)
    An accurate assessment of flows is essential for any study of the hydraulic performance of a sewer system or the pollutant removal efficiency of an effluent treatment plant. Flow measurement relies either on fixed flumes, ...
  • Public and private owners: getting the message across 

    Jefferies, Christopher (Ministry of Transport, Public Works and Water Management - The Netherlands, 2005)

    The aim of this research was to produce enhanced detailing and improved operation of in-ground SUDS. Data from on-site monitoring at three filter drain and three infiltration trench systems were analysed and the results ...
  • A review of vehicle related metals and polycyclic aromatic hydrocarbons in the UK environment 

    Napier, Fiona; D'Arcy, Brian; Jefferies, Christopher (Elsevier, 2008-06)
    This paper considers the importance of automobiles as a continuing source of persistent pollutants in the environment, using the UK as a case study. The mass of lead, copper, zinc and polycyclic aromatic hydrocarbons (PAHs) ...
  • Selecting SUDS in the Valencia Region of Spain 

    Casal-Campos, A.; Jefferies, Christopher; Momparler, S. Perales (IWA Publishing, 2012)
    This paper reports on a study of the implementation of sustainable urban drainage systems (SUDS) in two Spanish towns (Xàtiva and Benaguasil) as part of the EU LIFE+ Project AQUAVAL, which has been conceived to introduce ...
  • Session: management of drainage near source – disconnection/minimise surface water entering public drainage 

    Smith, K. W. S.; Jefferies, Christopher; Blackwood, David J. (IAHR/IWA, 2008-08)
    Many combined sewer networks are currently constrained due to lack of capacity. Surface water entering the network may have an impact on the local environment by causing additional spills from Combined Sewer Overflows ...
  • Site handbook for the construction of SUDS (C698) 

    Woods-Ballard, B.; Kellagher, R.; Martin, P.; Jefferies, Christopher; Bray, R.; Shaffer, P. (CIRIA, 2007)
  • Size distribution and diffuse pollution impacts of PAHs in street dust in urban streams in the Yangtze River Delta 

    Zhao, Hongtao; Yin, Chengqing; Chen, Meixue; Wang, Weidong; Jefferies, Christopher; Shan, Baoqing (Elsevier B.V., 2009)
    Particles of dust washed off streets by stormwater are an important pathway of polyaromatic hydrocarbons (PAHs) into urban streams. This article presented a comprehensive assessment of the size distribution of PAHs in ...
  • Smart SUDS: recognising the multiple-benefit potential of sustainable surface water management systems 

    Jose, Roshni; Wade, Rebecca; Jefferies, Christopher (IWA Publishing, 2014-12-08)
    How can we make sustainable urban drainage systems (SUDS) smart? SUDS help us to manage surface water runoff from urban environments but they are capable of delivering much more. This paper looks beyond the water quantity ...
  • The social dimension of stormwater management practices in urban areas 

    Apostolaki, Stella; Jefferies, Christopher (VDM Verlag Dr. Müller, 2009)
    Heavily urbanised areas often face severe flooding incidences due to increased urbanisation and lack of permeable surfaces. A range of stormwater management practices are used in urban areas depending on several factors ...
