As the solution to his determined interrelations, Beyer provides an easy-to-handle nomogram, from which you can directly read off the water permeability for sands and gravels [Beyer64]. However, this method does not take sufficient account of decisive influencing factors (as e.g. the given bedding density). Thus, reliable data for the individual case of application can only be gathered by means of a test arrangement for the determination of the water …

The construction of sewers is often carried out using the open construction method. Depending on the design, this results in pipe-soil systems with different external loads on the sewer. To understand these relationships, the soil mechanical and hydrogeological principles for characterizing the subsoil are explained. After completing this module, you will have a sound knowledge of how: - to differentiate between soil types;
- to identify the influences of grain shape and grain size distribution on the practical construction properties of the subsoil and
- to name the different appearances of water in the subsoil;
- to determine the water permeability of the soil for a constructional assessment of the soil.

Drinking water scarcity is a global issue, including in Sweden, where it’s also used for crop irrigation and various industrial operations. This practice is neither sustainable nor efficient. Hence, MDU has launched an innovative research project aimed at developing efficient techniques to convert industrial process water and wastewater into a valuable asset for food production.
