Learning objectives: Upon completion of this course, the student should be able to evaluate which methods are suitable for a given study area, and decide what kind of hydrogeological surveys are necessary for:

• Management and protection of groundwater resources

• Studies of contaminant spreading in groundwater

(3)

Geophysical methods:

- georadar, - seismics,

- electrical resistivity

Drilling and testing groundwater wells

Water sampling and chemistry:

- groundwater, lakes and rivers

Estimation of hydraulic properties:

- capillary sampling - infiltration tests - slug tests

- salt dilution - flow meters - slug tests

- pumping tests - grain size analysis

Torshovdalen & Iladalen

in collaboration with the Municipality of Oslo Gaustad Catchment

in collaboration with Norconsult

We will address some typical challenges within hydrogeology:

- Storm water management (infiltration) and water balance in a changing climate - Water quality and pollution sources in urban areas

- Risks related to construction and thermal energy exploitation and learn which methods are relevant for mapping and remediation.

2020 ERFARINGER FRA ÅRETS FELTKURS

• Antropogene masser og leire er vanskelige å karakterisere

• Timing, infrastruktur og linere etc. skaper utfordringer

• Positivt å samarbeide med kommune og private aktører

• Aktuelle utfordringer er inspirerende, og resultater nyttige

20 21 FREMTIDENS FELTKURS

• Vi kommer nok til å kjøre en tradisjonell variant i 2021

• Vi jobber med digitalisering og tilgjengeliggjøring av læringsressurser – følg med, følg med 

• Positivt å utvide omfang av metoder (e.g. borehullslogger)

• Men ett kurs kan ikke favne alt …..

Hvilket metodesett burde man presentere i et eget kurs om urban hydrogeologi?

Stikkord: sprekkeakviferer, infrastruktur, leire, geoteknikk …

Tusen takk til årets flinke gjeng av studenter!! Og alle de gode hjelperne.

Læringsmålene ble oppnådd og flere flinke hydrogeologer kommer på markedet snart!
