Groundwater Modelling

Computer modelling is the use of the high speed of a computer processor to solve the mathematical equations that govern the physical behaviour of a system.

OGI has developed in-house computer models to simulate the behaviour of groundwater, heat and dissolved contaminants within the ground. This results in the ability to simulate and predict changes in water and soil pressures, dissolved contamination flowing within groundwater, and the ground temperatures and available heat resource.

Benefits to our clients include:

1. Calculation of required pumping rates to sufficiently lower water table to target level.

2. Optimisation of borehole positions for a dewatering system.

3. Prediction of the extent of drawdown outside a dewatered site.

4. Calculation of groundwater pressure against a sheet pile cofferdam.

5. Simulation of a ground energy collector field and assessment of heat resource.

6. Calculation of stored energy capability for a ground heat battery.

7. Simulation of heat migration into the ground during a summer winter cycle.

8. Simulation of the abstraction and reinjection in an open loop system.

9. Simulation of the movement of a dissolved contaminant plume in an aquifer.

10. Calculation of the increased heat capture from a Muovitech heat collector.

Other geotechnical modelling capability includes:

1. Simulation of stress and pore water pressure in gassy soil during consolidation.

2. Simulation of stress and pore water pressure in gassy soil under tide loading conditions.

3. Simulation of stress and pore water pressure in gassy soil under wave loading conditions.

4. Simulation of stress and pore water pressure around a buried pipeline under wave loading.
