Hydrologist
Hydrologists collect and interpret data from natural and artificial waterways to solve environmental and sustainable problems
As a hydrologist, you'll be involved in the monitoring, management and protection of water and water resources in commercial, environmental and academic settings.
They ensure the effective flow of water through channels and pipes for the engineering and control of water provision. Their work contributes to the efficient planning, development and sustainable use of natural and domestic water resources, ensuring water is supplied in the most cost-effective manner.
Responsibilities
As a hydrologist, you'll need to:
- supervise the collection, processing and evaluation of data for water resource planning and flood management
- use computer modelling packages to assess the most effective methods of managing available water in a particular area, including for forecasting and strategic planning purposes
- analyse the effect of environmental changes on water flow
- study the effects on flows brought about by changes in land use, such as afforestation or crop irrigation
- plan responses to specific weather conditions, such as droughts and floods, and assess their impact on water catchments and supplies
- estimate water yields, taking into account natural drainage
- assess the relationship between rainfall, run off, and soil and rock features
- investigate factors affecting acidity, nitrate levels or other diffuse pollution of surface water
- calculate and audit water resource systems and analyse this data
- determine licences for companies and bodies requesting to use river resources
- implement relevant regulations
- deal with enquiries from external bodies and individuals, such as water regulators, consultants and researchers
- project manage the installation of river flow gauges
- liaise with specialists, consultants and clients
- provide feedback on drought and water resource plans produced by water companies
- oversee data collection on-site, carried out by hydrometrists and other staff
- develop computer systems to improve the efficiency of data collection and analysis and keep up to date with new research and techniques.
With experience, you may take on the role of project manager with responsibility for the technical management of a variety of hydrology projects, including:
- water resources planning
- reservoir and river flood risk assessment
- water quality
- drainage.
Extra activities are likely to include:
- ensuring delivery of a project on time and to cost and quality targets
- contributing to the management of the business, including financial monitoring, business and strategy development
- seeking out and exploiting new opportunities.
Salary
- Starting salaries typically range from £18,000 to £25,000.
- With experience, more senior hydrologists can earn £45,000.
- Principal hydrologists can earn more than £50,000.
Some employers provide performance-related pay schemes. Other benefits may include a car allowance and share-option schemes in private consultancies.
Income figures are intended as a guide only.
Working hours
Working hours may include regular extra hours, but not usually shifts. Long hours, and working under pressure, may be required in an emergency, such as a flood.
Flexible working is available at some companies, where there may also be some flexibility to allow occasional working from home. Part-time work and career breaks may be available with some employers.
What to expect
- The amount of site-based work outside the office varies between roles. Time may be spent out of the office at meetings with clients, consultants, regulatory bodies and stakeholders.
- Work is typically project-based, providing a good level of variety. Projects are often team-based, while independent work may involve liaising with colleagues and external agencies.
- There are currently more men than women in the profession.
- Travel within the working day is usual. Overnight absence from home and overseas travel may be required.
- Overseas work is available, particularly through work with international consultancies.
Qualifications
There are no undergraduate hydrology degrees in the UK, as hydrology does not exist as a subject in its own right. However, relevant degree subjects that cover elements of hydrology include:
- civil and environmental engineering
- ecology
- environmental management
- environmental sciences
- geography (with a physical science base)
- geology
- soil science.
Entry with a HND only is rare.
Detailed training in hydrology is usually covered at postgraduate level. Although not necessary for all jobs, a postgraduate degree is recommended - and increasingly required at senior level, due to competition for posts.
Postgraduate courses vary in focus, so it's important you choose a course that matches your career aims. Subject areas include:
- aquatic resource management
- environmental engineering
- environmental management
- flood risk management
- hydrology and water quality
- water management
- water resources.
The BHS has a list of MSc courses that provide training in hydrological processes, techniques and solutions to environmental issues.
Contact individual institutions for course information and further details on entry requirements.
A small number of studentship bursaries are available, in which the British Hydrological Society (BHS), in partnership with the JBA Trust, will provide between £2,000 to £2,500 towards the costs of MSc related to hydrology at a UK higher education institution. Applications should be made via Studentship Award Scheme.
The Centre for Ecology and Hydrology (CEH) collaborates with universities across the UK and internationally to input scientific and supervisory expertise into PhD student projects. See CEH Studentships for more information.
When choosing an undergraduate or further degree it is important to consider whether it is recognised and accredited by the professional body to which you may wish to apply for membership in the future, for example, either the:
- Institution of Civil Engineers (ICE)
- Chartered Institution of Water and Environmental Management (CIWEM)
Skills
You'll need to show evidence of:
- sound technical knowledge
- strong oral and written communication skills
- numeracy and a good understanding of mathematical modelling and IT programming skills (depending on the role)
- analytical skills
- people skills, for engaging with a range of different groups
- project management skills
- a high level of commitment and self-motivation
- a logical, methodical approach and good organisational skills
- a flexible approach to work and the ability to adapt to change and deal effectively with varying situations
- a full UK driving licence is usually a requirement.
Work experience
You should try to gain relevant experience by completing a work placement in a relevant or related field, such as hydrometrics.
Working on volunteer conservation projects shows commitment to the area and will help you develop your skills and make useful contacts. Experience of working for charitable groups and non-governmental organisations (NGOs) such as The Rivers Trust is valuable.
Competition is strong because of the level of specialisation, so you'll need to be as proactive as possible in your search for a work experience opportunity.
