A basic knowledge of soil science and physics as a discipline is assumed.

On this basis, the aim is to provide a quantitative description of soil architecture and the physical processes in the soil pore system.

Graduates of this programme go on to work in advisory services, for city or regional governments, private companies, or NGOs.Surface exposure dating using terrestrial cosmogenic nuclides (TCN) is an established and reliable method to date landforms and has been applied for dating glacial advances and retreats, erosion history, lava flows, meteorite impacts, fault scarps, and other geological events.Within landslide studies, NGU applies TCN dating to determine ages of rockslide events and the age of sliding surfaces in order to determine past long-term displacement rates Earth is constantly bombarded with cosmic rays that are high-energy charged particles.Although dating with this method is expensive and the entire process takes a long time, TCN dating has the advantage that the dateable material is produced by the rockslide event itself by exposing fresh material surfaces to the cosmic rays.With the accuracy of modern instruments general every surface older than about 1000 years can be dated and the uncertainty limits today lie below 10% of the age.Rather than just making minor changes to existing production systems, these students are out to rethink the entire production cycle by optimising production goals as well as environmental targets.
