Specialist hydrology and geomorphology advice

Specialist hydrology and geomorphology advice

Our specialist work on river processes and flows is carried out by Professor Malcolm Newson.  Malcolm is internationally respected for his expertise in hydrology and geomorphology and has over 40 years’ experience in research and applications in hydrology river processes, and freshwater and wetland conservation.


Impacts of bridges and weirs


Rivers are complex, dynamic systems. Before making changes to in-river structures, it is vital to understand the likely impact of any course of action. It is particularly important to understand how the river itself will respond. We identify sustainable actions to protect structures affected by rivers, including, where needed, proposals for
improving fish passage.  We can help you submit all relevant applications for
development works.

Human impacts on rivers and wetlands

protected rivers buttonAssessing the impact of proposed development on rivers and wetlands is now compulsory. We are river and wetland remediation experts; we have helped to develop screening tools and decision-support databases used by trained professionals, and we can help you. We carry out site-specific assessments and offer recommendations
for river and wetland remediation, including risks to infrastructure and
potential flood risks.

Reconnecting rivers

impacts of abstraction

Major water abstractions and transfers affect a river’s ecosystem. Their impact on flow and sediment transfer must comply with European laws. Correcting the physical habitat of a disconnected river can vastly improve its ecology. We can give you expert judgement on suitable flow regimes and sediment inputs. This assures healthy riverbed processes downstream of major structures.

Post-flood assessment

water transfersFloods often cause a lasting impact on communities. They can also cause a river channel to move and the river will behave differently as a result. There are usually good reasons to move the river back to its original position; however in some cases,
the post-flood course is the most sustainable.  We advise on the best course of action
for an individual site.



We train environmental professionals on the internationally-recognised River Habitat Survey and Fluvial Audit techniques, enabling them to carry out rapid, specialist assessments on their own rivers.


We can offer you advice on hydropower schemes, including site evaluation and
impact assessment. We can help you identify what is needed to apply successfully for
planning and environmental consents.
