Premier Surveys has vast experience in completing complex watercourse and channel surveys of all characteristics. We have a long-standing relationship with the Environment Agency, having managed and delivered a wide range of major projects for the Environment Agency and flood modelling consultancies. All surveys are delivered to the latest surveying specifications provided by the Environment Agency. Our surveyors have the added benefit of extensive and specialist river-modelling knowledge and have completed the DEFRA Water
and Flood First Responder training course to ensure they are appropriately qualified to work safely near water.
Flood Warning Expansion Project – A national project to expand the current flood warning system to include 100% of high-risk properties. Objectives included creating c230 new flood warning areas and associated flood warning thresholds, over 200 forecasting models and to install over 200 new monitoring sites. We surveyed more than 100 locations, completing bank top, cross section and property threshold survey work to facilitate the creation of new forecasting models and flood warning thresholds.
Chelmsford Future Flood Resilience – The survey included the river channel and bank top crest survey of the main rivers in Chelmsford, River Wid, River Can and River Chelmer. The scope included raised features that were set-back from the rivers such as walls, banks, roads and paths, as well as threshold levels for property and underpasses and three gauging stations – Beach’s Mill GS on the River Can, Springfield GS on the River Chelmer and Writtle GS on the River Wid.
Skegness Sea Wall Monitoring Survey – The Environment Agency has been undertaking beach nourishment campaigns along the Lincolnshire coastline to monitor the receding beach line which affects the condition of the coastal defence structure. As part of this project we conducted a multidiscipline survey along a section of sea wall stretching approximately 560m in length.
Great Ouse Strategic Flood Risk Interventions Study – We surveyed a section of the River Great Ouse which stretched approximately 21km in length, including more than 200 cross sections over 5 connected channels from St Neots, Bedford, Milton Keynes and Leighton Buzzard.
Rother and Romney Silt Surveys – The survey project included 7 channels which culminated in approximately 300 cross sections. Deliverables included CAD, ISIS, EACSD and silt volume calculations.
River Trent Nottingham – A channel survey of 6 tributaries of the River Trent with a combined length of 15km and over 200 cross sections. Deliverables included data in EACSD v3.2 format used for hydraulic models.
Thames & Anglian Regions – Survey validation contract to verify conformance of survey contractor’s work in channel surveys, topographical surveys, GPS survey control and beach profile monitoring.
Leicester Flood Defences Survey – The survey included 78 assets with a combined length of approximately 30km.
Derbyshire Flood Defences Survey – The survey included more than 200 assets spread over a 20km expanse.
Ashfield District Council, Kingsmill Reservoir – Survey of hard-bed and soft-bed silt levels to determine overall silt amount.
A13 Lea River Bridge, London – Survey of the river-bed profile and bridge structure for the design of a pedestrian walkway.
Ware Sea Cliffs, Dorset – Profile survey of geologically unstable cliffs for coastal protection measures.
As part of a wider beach monitoring project focussing on a large section of the sea wall in Skegness, we conducted a multidiscipline survey along a 560m stretch of the wall to determine the condition of the sea wall and identify any movement.
Premier Surveys delivered a large channel survey at the River Frome and its tributaries. The project involved more than 600 cross sections and a total watercourse length of 70km, including weirs, culverts, sluices, flood defences and hydrometric gauging station sites.
Our watercourse surveyors delivered a project at Upton Mill House in Nottinghamshire, providing detailed cross-sections and long sections of the culvert that ran beneath the Mill House. Our clients used the data to inform the design of a new fish pass.
We delivered a large culvert scanning project on behalf of the Environment Agency. We located the relevant manholes and performed inverted scanning to capture the data, from which we determined the alignment, position and size of the stream running below ground.
