Groundwater Control: Design & Modelling Workshop
Held at the Mónaco Hotel, close to Faro Airport, Portugal, this practical 3-day hands-on groundwater control design & modelling workshop will give participants the skills to:?
The 3-day Practical Workshops takes place over 18 hours from 12:15 Wed 22nd February to 15:15 Fri 24th February.?The workshop is held at the Mónaco Hotel, Faro, Portugal.
The cost of the 3-day workshop is €900, and includes a license for two items of practical software tools for modelling groundwater, together with detailed course notes.? A workshop place can be reserved by contacting OGI at [email protected] or by calling us by telephone at +44-191-378-7010.
The workshop is limited to 20 participants, and is designed to be an intensive, but enjoyable, 18 hours of critical learning in this important field of groundwater control & management.
The participant will receive focused expert teaching and hands-on guidance of the critical hydrogeological concepts required for the forecasting of groundwater behaviour.?This will include presenting the concepts of hydraulic conductivity, transmissivity, aquifer storage, leakage and distributed recharge, and how they influence groundwater behaviour. Extracts of the notes provided are presented at the end of this article.
Particular attention will focus on demonstrating the key design components of an industrial groundwater control system for the dewatering of a construction site.?This would include the optimum borehole drilling diameter and depth, casing and screen diameter, slot size, filter size, and pumping methodology (electro-submersible, suction or ejector system).
The participant will receive hands-on training on the use of OGI’s own modelling software, GEMOS-LITE and CVM11-FLOW, for which a license is provided as part of the event fee.?This software simulates the lowering of the water-table and piezometric head under both steady-state (GEMOS) and transient conditions (CVM) as a result of abstracting groundwater from a single well (CVM) or multiple wells (GEMOS).?Whilst individually simple and easy-to-use, the combination of these two models provides a very powerful groundwater forecasting tool, which is both effective and efficient to apply in practice.
The experts will also deliver a seminar describing aquifer pumping tests in practice.?This is a test where a single abstraction borehole is pumped at a measured flow rate, with the drawdown of the water-table observed and documented over time at a series of observation wells or piezometers.
Using the software provided, the participants will organize themselves to work in groups of two or three to solve a series of prepared pump test case study results.?The objective is to train each participant to back-calculate the governing aquifer hydrogeological properties.
Next, participants will use the back-calculated governing properties as input to the software to predict the pumping rate from a multi-well groundwater control dewatering system necessary to lower the water table to a required depth, providing safe working ground conditions.
The main objective of the 3-day event, is that every participant becomes confident at solving groundwater problems, using a range of techniques, from computer modelling software to simple hand calculations.
Another major advantage of the approach delivered at the event is that the modelling techniques provided are simple and straightforward to apply.?This approach then acts as an intermediary between hand calculations and advanced mathematical modelling.?It is all too often that a groundwater engineer/hydrogeologist embarks too early in developing an advanced groundwater model that can take many weeks to build and calibrate.?The software provided with this event enables the participant to build a model, input the data, execute the simulation and produce meaningful results, within one or two hours.?Whilst, this approach is limited to two-dimensional groundwater behaviour, the approach is normally sufficient to forecast most groundwater conditions encountered in construction dewatering.

Workshop delivered by experienced industry experts
The workshop and associated seminars are delivered by industry experts, who make their living by solving complex problems on a day-by-day basis.?To put in perspective, over the past 20 years, we have provided design solutions to over 300 groundwater projects, with all designs implemented on site.?It is this experience that we will be sharing during the 3-day workshop.?A brief description of each of the three presenting industry experts is below.
Informal consultation
Whilst the event duration of 18 hours is delivered over three days, i.e. 12:15 Wednesday 22nd to 15:15 Friday 24th February, there is the opportunity to arrive earlier on Wednesday, and stay later on Friday, to have individual discussions with Dr Thomas should a participant have a specific groundwater problem to discuss.?Furthermore, during the workshop, it will be feasible to set up the models to aim to solve such an individual problem, with guidance from the delivery team.
Accommodation at Hotel Monaco
The participant will be responsible for booking and paying for accommodation directly to the hotel at [email protected] quoting OGI-2023 to for the conference.
The hotel booking fee will cover mid-morning coffee and afternoon tea, together with a sandwich lunch.?In the two evenings, Wednesday and Thursday, we will likely have dinner as a group, but this is optional, and each participant would pay for their own dinner.?
There are many excellent seafood restaurants within walking distance of the hotel, and these dinners are always an enjoyable event.

Travel to Faro
Flights to Faro are very frequent and convenient.?The event starts officially at 12:15 on Day one, to enable participants to arrive at Faro International Airport on Wednesday morning, or on the express train from Lisboa.?There are convenient flights on Wednesday morning direct from many European cities, but for those that have not visited the Algarve before, we would recommend arriving earlier to explore the area.?For those that arrive earlier, or stay later, the experts can provide informal discussion about individual groundwater problems from 10:15 on Wednesday morning, and until 17:15 on Friday afternoon.
