Groundwater CONTROL Field Testing, Monitoring and Modelling

SEMINAR AND WORKSHOP

Friday 23 March 2018 @ 09:00 – 16:30

OGI Groundwater Specialists, DURHAM, UK

£195 + VAT Per Person

Who Should Attend

This seminar and workshop is aimed an industry professionals who work within the construction industry. It provides essential CPD for:

·        Hydrogeologists

·        Geotechnical Engineers

·        Engineering Geologists

·        Temporary Works Engineers

·        Engineering Consultants

·        Project Managers

Workshop at the Groundwater Engineering Academy

ABOUT THE SEMINAR

This seminar and workshop will present you the fundamentals of groundwater control. This will include the theory of groundwater flow through porous saturated ground, field pump testing and monitoring, modelling aquifer pump and injection tests, and the simulation of groundwater control systems. Participants will benefit from hands on modelling using complimentary groundwater modelling software GEMOS-LITE and CVM10-LITE. Attendants will get to participate in a model size 25m long aquifer pump test, which will include setting up the pump, monitoring groundwater levels, and modelling results using CVM10-LITE.

CONTENT

  1. Overview of the Theory of Groundwater Behaviour
  2. Pump testing procedures
  3. Conducting pump testing from model aquifer in practice
  4. Measurement of pumping rates and monitoring of drawdown
  5. Input of data into spreadsheets
  6. Translation of data to metres OD
  7. Simulation of monitored water table response using a Finite Element Model (CVM10-LITE)
  8. Back-calculation of aquifer parameters using Finite Element Analysis
  9. Design of Groundwater Control Systems using Computer software
  10. Overview of Groundwater Control techniques and cases studies.

CVM10-LITE

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.

Groundwater Control Modelling in Practice 2

GEMOS-2017

Whenever an excavation is made below the water table there is a risk that it 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 dewatering system consisting of multiple wells 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.
