GROUNDWATER CONTROL DESIGN & MODELLING IN PRACTICE
FOUR DAYS OF PRACTICAL WORKSHOPS
€1750 + VAT Per Person
Who Should Attend
These workshops are aimed an industry professionals from across Europe who work within the construction industry.
It provides essential Continuing Professional Development for:
· Geotechnical Engineers
· Engineering Geologists
· Temporary Works Engineers
· Engineering Consultants
· Project Managers
ABOUT THE WORKSHOPS
Join us for four days of practical workshops where you will learn the fundamentals of groundwater control design and hands-on application of the modelling of groundwater flow and contaminant transport within a groundwater flow field.
Receive complimentary licenses for OGI’s groundwater flow and transport models, CVM10-PRO and GEMOS-LITE. Apply these models to many practical groundwater case studies.
This event is intended for practicing engineers or hydrogeologists who have some existing understanding of groundwater flow basics, and have a desire to increase their design and modelling skills.
THIS COURSE WILL BE TAUGHT IN ENGLISH
DAY 1 – Groundwater Control Design with GEMOS
- Aquifer Properties – Permeability and Storage
- Darcy’s Law and the Well Flow Equations.
- Well Performance – Screen Yield and Ground Yield
- Multiple Well Analysis using GEMOS (Groundwater Engineering & Management Optimisation Software)
- Simulate multi-well water table drawdown beneath a shaft
Whenever an excavation is required below the water table there is a high risk that the sides will become unstable or flood unless measures are taken to control the groundwater in the surrounding soil. This seminar and workshop will provide guidance on how a multiple well groundwater control system can intercept the groundwater to prevent inflow to the excavation. This will be illustrated using GEMOS-LITE, a tool for simulating multi-well steady state groundwater flow in confined and unconfined aquifers.
Below: Simulating a groundwater control system to enable the lowering of the water table beneath a shaft.
DAY 2 – Introduction to Numerical Modelling using CVM (Radial Finite Element Model)
- Numerical Groundwater Modelling Techniques
- The Groundwater Flow Equation
- Setting up a Finite Element Model
- Simulating an Aquifer Pumping Test.
The attendee will use CVM10-LITE to model the pump test. It is a finite element model for transient groundwater flow in confined, unconfined and leaky aquifers. This model enables the user to determine soil parameters such as permeability, storativity and leakage coefficient from aquifer pump and injection tests.
Below: Simulating the results of a pumping test in London Chalk to assess Transmissivity and Storage Coefficient.
DAY 3 – Contaminant Transport
Modelling using CVM
- Principles of contaminant transport modelling
- The advection-dispersion equation
- Modelling contaminant migration in a uniform groundwater flow field
- Combined groundwater flow and contaminant transport models
- Illustration of 2D contaminant migration using OGI case studies
DAY 4 – Case Studies using PLAXIS 2D and SEEP/W
- Demonstration of the application of 2D groundwater flow model SEEP/W and coupled groundwater flow and soil deformation using PLAXIS 2D. Presentation of a number of OGI case studies, including simulation of:
- Groundwater flow under a cut-off wall into an open excavation.
- Pore-pressure relief wells inside an excavation to prevent base heave.
- Groundwater control around battered excavation to increase soil strength and stability.
· Learn from experienced professionals in industry
· Increase your understanding of groundwater control theory and modelling
· Simulate groundwater control systems
· Model aquifer pump and injection tests
· Network with industry professionals
Each day includes lunch and refreshments, and there will be the opportunity to apply the OGI software to solving engineering problems of your own.
Each attendant is required to bring a Windows laptop PC which has Microsoft Office installed. OGI software will then be installed on your own personal laptop.
