For: Northern Ireland Cooperation Overseas - 2012
As part of the EU programme for Cooperation for Stronger Municipalities, the Consultant was appointed by NICO to provide expert assistance on river engineering proposals for the Municipality of Hani I Elezit in southern Kosovo. The Municipality is in receipt of Grant Aid for asbestos clean up of the River Lepenc through the urban area, and as part of its Urban Development Plan wishes to enhance use of the riverside for the local community. The short-term contract entailed a review of historical flood risk, river protection and enhancement options, and proposals for riverside amenity improvements integrated into the engineering works.
RIVER MODELLING AND FLOOD DEFENCES AUDIT, RIVER STOUR, DORSET
For: Hall and Woodhouse Brewery, Blandford - 2005
In preparation for redeveloping part of their historic brewery site, Hall and Woodhouse appointed the Consultant to prepare a detailed 1D hydraulic model of the River Stour, to assess the floodplain extent and provide precise estimates of varying flood levels. The new HEC model showed excellent calibration with historical floods. The model was used to assess flood risk to new development, and to determine safe floor levels and the height and layout of new and improved flood defences.
BRIDGE HYDRAULIC DESIGN & FLOOD RISK ASSESSMENT, RIVER AVON, WILTSHIRE
For: Wiltshire County Council - 2002
Cow Bridge near Malmesbury is a sub-standard cast iron bridge carrying the B4042. The client's proposal is to replace the bridge with a more modern reinforced concrete design. A detailed flood study was required to model the river and assess the hydraulic impacts of the old and new structures. The old bridge is a complex multi-arch structure on piers, requiring advanced analysis in HEC-RAS. An excellent model calibration was achieved against historical flood data.
TERM CONSULTANCY IN HYDROLOGY AND HYDRAULICS

VIADUCT HYDRAULIC DESIGN & FLOODPLAIN MAPPING, AFON DYFI, WALES
For: Powys County Council, Trunk Road Agency - Ongoing
Powys County Council has the Trunk Road Agency for North Wales, and proposes to improve substantially the A487 crossing of the Afon Dyfi at Machynlleth, north Wales. River and floodplain modelling of this, the largest river in north Wales, in addition to cost-benefit appraisals, will be required to establish a workable scheme. Options include hydraulic design of a new bridge, and raising of the existing causeway.
BLOCKAGE RISK ASSESSMENT, PAXCROFT BROOK, WILTSHIRE
For: Environment Agency South West and Gallagher Homes Ltd - 2000
Paxcroft Brook has been the subject of increased summer flows from new development, and the watercourse passes through a confined 200 m long culvert at its downstream end. Concern was raised about blockage risk on this structure, and its safety implications. A statistically based risk evaluation study was carried out using methods evolved by the consultant to identify the probabilistic risks of blockage, the most likely causative factors, and to advise on improved safety design and an improved maintenance programme.
BRIDGE HYDRAULIC DESIGN AND FLOODPLAIN ASSESSMENT, SEMINGTON BROOK
For: Wiltshire County Council & Ringway Parkman - 2000
Wiltshire County Council Highways Division is planning a series of new strategic highway links in the county. The A350 diversion will cross two major watercourses, including the Semington Brook. The crossing will require a major new bridge and associated embankments across the floodplain. Various bridge spans were tested with a HEC-RAS model, and it was concluded that the optimised scheme involved a 66 m span, together with floodplain excavation works. The consultant devised a highly efficient series of excavation zones under the bridge which compensated fully for afflux and floodplain loss whilst minimising cut volumes. Job sheet available - 1046
CATCHMENT HYDROLOGICAL MODEL AND RESERVOIR DESIGN, PENARTH, S.WALES
For: Welsh Development Agency/Parsons Brinckerhoff - 2000
A new housing development will impact on the flood sensitive areas of Cog Moors around Barry. A catchment hydrological model was developed using RIBAMAN, which examined various site discharge management strategies, and was used for detailed design of the site attenuation reservoir, which was specially constructed as an ecological habitat for dragonflies.
FLOOD CONTROL RESERVOIR DESIGN, GALMINGTON STREAM, TAUNTON, UK
For: Tesco Stores Ltd., White Young Green - 1999
Following hydraulic studies of the Q100 floodplain at the new proposed store, the consultant was appointed to devise an upstream flood attenuation scheme to provide peak flow control and compensatory storage. The design utilised the principal of 'rising limb attenuation' advocated in the Urban Water paper of 1999. The location of the reservoir (being upstream of the urban areas) required a specialised form of hydraulic control in order to achieve a reduction in downstream peak flows, whereby only the early part of the hydrograph is attenuated, corresponding to the time of the urban runoff peak downstream. This design minimised the storage volume of the reservoir without compromising its effectiveness. Constructed in 2000. Job Sheet available - 1028
RIVER MODELLING AND RIVER REALIGNMENT, LLANGEFNI, ANGLESEY, N. WALES
For: Safeway Stores Ltd., White Young Green - 1999
The proposed site required a river diversion and new culvert to Q100 standard of the Afon Clai. A particular problem was the sharp bend needed at the upstream end of the diversion, overcome by environmentally sympathetic design of a stilling pool and cascade arrangement. Full hydraulic modelling using HEC-RAS was required to design the new channel and culvert, and incorporate the backwater effects from the larger Afon Cefni immediately adjacent to the site.
FLOOD RISK ASSESSMENT AND COMPENSATORY WORKS, WATCHET STW, SOMERSET, UK
For: Wessex Water Engineering Services - 1999
An upgraded Sewage Treatment Works (STW) is required at Watchet in conformance with new EC directives. Flood design levels were required for the works, and the Environment Agency also required an impact assessment of the effect of works embankments on the existing floodplain. An existing river hydraulic model was modified, expanded and used to assess proposals. Job Sheet available - 1035
BRIDGE HYDRAULIC DESIGN AND FLOODPLAIN ASSESSMENT, WOTTON, UK
For: Renishaw Plc and Pinnacle Consultants Ltd. - 1998
The Renishaw site is being provided with a new access road and bridge crossing the floodplain of the Little Avon, Wotton. A river hydraulic model was required to model the existing floodplain and determine Q100 levels. A revised model incorporating detailed bridge and highway embankment details enabled optimised design to minimise bridge afflux. Floodplain mapping of the site used the MapInfo GIS system. Job Sheet available - 1032
RIVER CHANNEL RE-DESIGN, GALMINGTON STREAM, TAUNTON, UK
For: TESCO Stores Plc and White Young Green - 1998
A food retail store is currently proposed for a site adjacent to the River Tone and Galmington Stream in Taunton. The existing site is known to be susceptible to 1 in 100 year flooding. An Environment Agency requirement was to show that flood storage could be replaced following development by means of an improved and enlarged river channel. A 2 stage flood channel was designed using the HEC-RAS software, including a new access bridge. The scheme design showed that flood level risk to upstream properties could also be significantly reduced by an improved channel.
R&D PROJECT ON STRUCTURE BLOCKAGE RISK ASSESSMENT
For: Environment Agency (South West Region) - 1998
A study was commissioned to provide interim guidance on how best to consistently predict and mathematically model debris blockages at river structures. In association with Kennedy and Donkin, Brian Faulkner acted as the river modelling and risk assessment consultant to the project. The output included a national standard for blockage modelling procedures in Section 105 studies, a sophisticated blockage prediction tool on spreadsheet, and guidance on risk assessment applications. The software was produced and distributed on CD-ROM. Job Sheet available - 1018
RIVER CHANNEL REALIGNMENT, RIVER STOUR, KIDDERMINSTER
For: White Young Green Consulting Ltd & Tesco Stores Ltd. - 1998
The Brinton's wool mill site in the centre of Kidderminster is due for a redevelopment into a major shopping precinct. The River Stour runs through the centre of the site currently in the form of a lined rectangular channel. The consultant provided the hydraulic design and testing of a new, environmentally sensitive channel to the Q100 standard. The design was completed using the ISIS modelling software. The performance of existing side weirs had to be evaluated, and sizing of new culverts was also necessary. Job Sheet available - 1019
ASHTON VALE FLOODPLAIN IMPACT STUDY, BRISTOL
For: Terry Adams Ltd - Parkman UK - 1996
Extensions to landfill operations were proposed in the Ashton Vale area of Bristol. The area has a history of flooding, and was the subject of a flood alleviation scheme by Wessex Water in the 1970's. The Environment Agency required a detailed study of the impact on floodplain levels and river flows as a result of extensive potential infilling of the floodplain. Particular account had to be taken of fluvial - tidal joint probabilities. It was established that betterment to third parties could be provided by attenuating flows within landscaped reservoirs on site, which improved significantly the level of service of the original flood scheme, which had not included for tidal influences.
PAXCROFT BROOK FLOOD STUDY, WILTSHIRE
For: J.J. Gallagher Ltd - 1996
The 95 ha. residential development of Paxcroft Mead near Trowbridge was expected to cause flooding problems in the receiving watercourse. Use of a hydrological model in the study established that attenuation was not feasible. A flood defence scheme had to be designed and tested to the Q100 standard using the HEC-RAS software to satisfy Environment Agency requirements. Sensitivity analysis was required to determine worst case conditions with respect to the backwater effects of the major river downstream and a known restrictive culvert. The scheme was constructed in 1998.
