Groundwater CONTROL Field Testing, Monitoring and Modelling
DURHAM MODEL AQUIFER PUMP TEST

DURHAM MODEL AQUIFER
To provide a teaching resource for Hydrogeologists & Groundwater Engineers, here outside OGI’s office in Durham, we have built a 26m long, 1500mm deep, 700mm wide model aquifer. The DMA is excavated from silt clay made ground, and had been filled with medium sand. This week we are undertaking a two-hour pumping test. Pumping will take place from a pumping well at the end of the aquifer, with drawdown measured at 4-5 other locations by pre-placed piezometers.
As a bit of fun, would anyone like to back-calculate the average permeability and specific yield? We can have a competition who can come the closest. We will publish the data on our website, together with the back-analysis by students from the City University of London who are visiting Friday.
DATA FROM PUMP TEST
The data from each monitoring well is presented as Change in Water Level.
