Reservoir Hydrology and Hydraulics

Creating an on-site Reservoir Flood Plan 1 - JBA Consulting

This course covers the techniques and best practice used when undertaking flood studies of UK and Irish reservoirs, and in assessing low flows/deployable capacity. It covers in detail the guidance in the ICE ‘Floods & Reservoir Safety – Fourth Edition’ guide (FRS4) and builds on this to look at more complex flood studies and hydraulic analysis of reservoir systems.

This course is aimed at current and prospective reservoir panel engineers. It is also relevant to hydrologists and modellers working on dam and reservoir studies.

By the end of the course, you will be able to:

  • Define catchment area and other key catchment descriptors
  • Apply the methods in FRS4 and be able to sense check the results
  • Estimate low flows into a reservoir and deployable capacity
  • Estimate impact of land use change and climate change on flood and low flows
  • Estimate design and safety check flood hydrographs using current good practice
  • Construct a 1D routing model of a reservoir system
  • Estimate flood rise and available freeboard
  • Estimate spillway capacity including superelevation and hydraulic jumps
  • Estimate wave set-up and overtopping using EurOtop methods
  • Estimate wave overtopping flows and velocities
  • Design energy dissipation methods
  • Know when to use more detailed modelling approaches such as 2D, 3D and physical models

The course is delivered in a hybrid virtual and physical classroom environment in 4 sessions over a two-week period. This enriches the learning process and helps in fitting the training around busy schedules:

  • Session 1 (virtual delivery – 4 hours) – hydrology
  • Session 2 (virtual delivery – 4 hours) – hydraulics
  • Session 3 (classroom delivery) – 5 hours – case studies / hands-on exercises
  • Session 4 (virtual delivery – 1.5 hours) – re-cap on key learning points and further reading/information

A series of workbooks and spreadsheet toolkits are provided (together with worked solutions) to help embed the learning. Session 3 will concentrate on two case studies and involve team working in applying the learning to real-life scenarios.

The classroom delivery will be in central Leeds.

There is also the option to deliver the entire course as a 2-day classroom-based course.

Duncan Faulkner MA MSc DIC CWEM CSci FCIWEM

Duncan is one of the UK’s leading hydrologists and is Head of JBA’s Hydrology Division. He was a member of the original Flood Estimation Handbook research team and is the author of the Environment Agency’s ‘Flood Estimation Guidelines’. He has also contributed to guidance on small catchment flood estimation, use of local data in flood frequency estimation and the application of non-stationary methods. He is currently working on the Defra/EA research project on ‘Improving PMP and PMF estimation for UK reservoir safety’ as the lead technical author.

His 27 years of experience includes being the lead hydrologist on high-profile dam operation studies in Australia, Myanmar, Ireland and the UK.


Jeremy is a leading expert in hydrology and hydraulics with over 35 years’ experience gained from dam and reservoir projects in the UK, Ireland, Vietnam, Laos, Australia, Sri Lanka and India. He is a member of the UK Reservoir Supervising Engineers Panel.

He is experienced in hydraulic analysis including surge and transient pressure analysis, dam break and spillway hydraulics. He is familiar with 1D, 2D and 3D computational models and applying them to reservoirs and also in the specification and interpretation of physical models.

He has worked on projects ranging from new dam design to increasing existing spillway capacity and portfolio risk assessments. He is co-author of the CIRIA C786 ‘Culvert, screen and outfall manual’ and the Environment Agency’s ‘Blockage Management Guide’. He was a technical lead in the reservoir flood mapping in England, Wales, and Northern Ireland.
