We have significant expertise in designing and installing flow gauging stations, including modifications of existing gauging stations to facilitate fish passage (e.g. through retrofitting of baffles or adding a Larinier fish pass in compound with an existing gauging weir). We can advise on siting, choice of method/feasibility and design. We have also excellent working relationship with NIVUS GmbH, with whom we have worked closely in designing new transit time ultrasonic stations.
We have an impressive track record in relation to delivering strategic hydrometric studies:
 See Davis, R., Zaidman, M., Grew, R. & Garrett, K. 2010. Evaluating the benefits of the hydrometric network in England and Wales. Proceedings of the British Hydrological Society Conference, Newcastle University, July 2010.
All the data we collect and supply undergoes strict validation and data assurance processes before use/issue. We are also able to undertake independent validation or checks of third party data; a recent example being an independent review of the quality of hydrometric data collected by the Tweed Forum as part of their Eddleston Water Project.
Our team has been widely involved in defining procedures for data management and assessment of data quality, of which some of the higher-profile projects have included:
We offer a spot gauging service using our own Valeport Model 801 Electromagnetic Open Channel Flow Meter, which we operate in accordance with BS EN ISO 748:2007 and which undergoes calibration every three years by the manufacturer. Recognising those situations where specialist equipment is needed we also have expertise with hired instrumentation including OTT’s QLiner, Sontek’s RiverSurveyor and FlowTracker devices and RD’s Stream Pro ADCP.
We have carried out flow gauging for Natural Resources Wales, Essex and Suffolk Water, National Trust and Irwell Rivers Trust, Aire Rivers Trust, South East Rivers Trust and the Environment Agency as well as private clients (e.g. in support of hydropower assessments, abstraction licence applications, internal drainage boards/water level management plans).
Our team is highly experienced in the development of new, and in the reviewing of existing Stage-Discharge and Velocity-Index ratings. We use our innovative in-house applications to aid hydrometric data review and analysis. To date we have derived over 100 new stage-discharge ratings on behalf of the Environment Agency. We also run training courses on the topic of extrapolation of high flow ratings and use of modelling to extend high flow rating limbs.
We are expert trainers in hydrology (our team runs the foundation and advanced level training courses offered within the Environment Agency). We offer a range off-the-shelf courses covering theoretical and practical aspects of hydrological analysis but are equally able to provide tailored training based on real case studies and practical examples.

Whilst the primary responsibility for delivering water and wastewater services lies with the water companies, Local Planning Authorities can use the planning system to promote solutions which contribute to improving the management of water and provide other benefits, including:
Many development consents have archaeology and heritage related planning conditions. We have the expertise to specify mitigation measures and obtain local authority agreement to the proposals. We have experience of specifying watching briefs, strip, map and sample and open area excavations. We can also help you procure and manage specialist sub-contractors to implement the mitigation.
In line with the requirements of NPPF many development sites require pre-submission or pre-determination heritage surveys. We have extensive experience of negotiating with LPA Archaeological Advisers, specifying and designing evaluation surveys such as geophysical survey, evaluation excavation (trial trenching), LiDAR analysis and building surveys.
Identifying measures for the long term management and development of heritage assets within a property portfolio can significantly reduce the amount of time spent negotiating consents and identifying heritage work specifications. They provide a framework within which long term sustainable management of the historic environment can be implemented.
The historic environment contributes to a sense of place. There are many opportunities for new developments to harness the historic environment to give a sense of identity and place to new developments and link them to the surrounding landscapes. We can provide advice at an early stage of the design process to enable these opportunities to be recognised and incorporated adding value to the development design.
The wider setting and context of heritage assets is a key consideration within the determination of many planning applications, particularly those for infrastructure projects or development within or close to sensitive areas such as World Heritage Sites and Conservation Areas.
We have extensive experience of defining the setting and contribution this makes to the significance of heritage assets and assessing the effects of development on these settings.
These encompass the whole of the historic environment. They are designed to meet the requirements of NPPF and provide comprehensive assessment to meet the clients’ needs and reduce project risks from the outset.
Marc wanted to be part of an organisation with a strong set of values – more than words, one that supports and advances science and understanding to develop its staff and our wider professional community.
