Laboratory experiment: Simulation of groundwater flow as part of the hydrotechnics masters program

As part of the master’s program in Civil Engineering – Infrastructures, module Hydrotechnics, a laboratory experiment was conducted to simulate groundwater flow. Prof. Dr. Milan Radulović presented to students and colleagues the research to be carried out as part of a master’s thesis in Hydrotechnics.

 

Groundwater flow, which occurs within underground mediums, cannot be directly observed. However, in laboratory conditions, it is possible to create a partial replica of natural groundwater flow and understand its behavior under various hydraulic conditions.

 

During foundation excavation for construction purposes, selecting appropriate groundwater drainage techniques is crucial to ensure that work can be conducted in a dry excavation pit.

 

The GUNT Hydraulic Laboratory, acquired through the Erasmus+ SWARM project, specifically the GUNT HM 167 laboratory unit, allows for the simulation of groundwater inflow into foundation excavations from an underlying aquifer. Today’s experiment aimed to answer the following questions:

 

- What are the effects of an impermeable diaphragm around the foundation excavation combined with pumping from two wells? 

- Is it possible to achieve the necessary groundwater level reduction to enable work in a dry excavation pit? 

 

During the experiment, an iterative process was used to determine the appropriate capacity for simulated pumping from drainage wells. This process successfully lowered the groundwater level below the foundation excavation base, ensuring optimal conditions for construction activities.
