About the Workshops

Join us for a day and a half of practical field testing and workshops where you will learn the fundamentals of aquifer pump testing, groundwater control design & hands-on application of the modelling of groundwater flow.

The course will include a “hands-on” practical pumping test using OGI’s model aquifer. The test will be monitored by participants, and then later analysed using OGI’s groundwater flow software CVM10-LITE back in the office. Modelling skills will then be developed further by using software GEMOS-LITE and SEFCUT-2D to model groundwater flow to an excavation.

Aquifer Field Testing

• Undertake a groundwater pumping test in the field using OGI’s model aquifer.
• Measure and record groundwater drawdown in monitoring wells.
• Manually measure and record abstracted flow rates.
• Undertake the pre-test monitoring, monitoring whilst pumping, and the recovery test stages of testing.
• Learn how to analyse groundwater drawdown measurements against time (linear and logarithmic scales).
• Analyse the recorded groundwater drawdown measurements against distance (linear and logarithmic scales).

Dr Stephen Thomas

Eur Ing Dr Stephen Thomas is a chartered British and European Civil
Engineer, and Fellow of the Institution of Civil Engineers. He is a registered
Ground Engineering Adviser (RoGEP), with a first class honours degree in Civil
Engineering and MSc from the University of Wales, a Doctorate from Oxford
University and MBA from Durham University. Stephen is also an Honorary

Managing Director of OGI Groundwater Specialists which he founded 1989.
This year celebrates 28 years of continued business, solving groundwater
problems in soft ground throughout the UK and overseas.

GEORGE FRENCH

George French started working at OGI in 2015, soon after graduating from
Durham University where he achieved a MSci honours degree in Geoscience.
George is an expert in the modelling of complex groundwater control
systems, contaminant transport in groundwater flow fields, and coupled
groundwater flow and soil deformation problems. He also been involved in
the design and development of the latest OGI groundwater modelling
products such as CVM10-PRO.

DR JENNA ROBERTSON

Dr Jenna Robertson is an Engineering Geoscientist at OGI Groundwater Specialists Ltd.  She has worked at OGI since September 2016, joining the company after graduating with a PhD in Geoscience and Hydrodynamics from Durham University.

One of her main roles is the undertaking, and analysis of groundwater tests for temporary works.  Her analysis of groundwater testing has included; pumping tests, recharge tests, falling head tests, rising head tests and soak-away tests.   Jenna is also responsible for groundwater monitoring on a number of large scale projects.

DR GRAHAM RICHARDSON

Dr Graham Richardson is a Senior Groundwater Control Engineer with over 30 years practical experience in construction and environmental engineering environments.

He graduated in geology and environmental science and gained a PhD in Mining Engineering. He has been with OGI now for some 16 years, involved in assessment of project requirements, through pricing, design, testing and implementation of Groundwater Control projects.

Graham is at the forefront of OGI’s design implementation on site and is a regular presenter of seminars in Groundwater Control, Geotechnics and Ground Source Heating.
