[ID: 249] Trollberget regular stream sampling
Monitoring of water chemistry in several streams. Sampling twice per week with increased frequency during the spring flood.
[ID: 248] Degerö regular stream sampling
PI: Mats Nilsson
Monitoring of water chemistry in several streams. Sampling twice per week with increased frequency during the spring flood.
[ID: 236] Stortjärn lake water sampling
PI: Hjalmar Laudon
Lake Stortjärn is one of the most expansive research sites within the Krycklan catchment, both in terms of new projects and infrastructure development.
[ID: 235] Snowcat groundwater monitoring
PI: Hjalmar Laudon
In total, close to 20 wells are installed spanning from 5 m to over 150 m depth. The installations were made to cover the entire Krycklan catchment to investigate regional groundwater as well as allow more local studies of water pathways. The first wells were installed by the Swedish Geological Survey (SGU) in the 1980s and have been monitored since, whereas the majority was installed in 2012.
[ID: 234] Russian wells groundwater monitoring
PI: Hjalmar Laudon
The Kallkäls-mire is the source area for stream C4, and the location of the “Russian wells”. These wells are a set of piezometers allowing sampling at different depths in, and below the mire.
[ID: 233] S-transect groundwater monitoring
PI: Hjalmar Laudon
The S-transect was installed 1997 and has been sampled monthly since. The transect consists of ceramic suction lysimeters at 5-7 depths in three plots: the riparian zone 4 m from the stream (S04), 12 m from the stream (S12) and in the up-slope mineral soil 22 m from the stream (S22). The installations are made so that samples can be collected all year by using a heating cable where the water passes through the frozen soil. The hydrology is focused in the upper horizons due to the hydrological conductivity which increases exponentially towards the soil surface.
[ID: 232] Snow lysimeters
PI: Hjalmar Laudon
Melt water from snow collected at three different locations within the Svartberget catchment. The water is collected several times during snow-melt and analysed.
[ID: 229] Weekly stream sampling
PI: Hjalmar Laudon
Monitoring of stream water at 3 fixed sites (#2, 4 7) within the Svartberget catchment, sampling once per week year round.
[ID: 228] Regular stream sampling
PI: Hjalmar Laudon
Monitoring of water chemistry in several streams. Sampling twice per week with increased frequency during the spring flood.
[ID: 224] Monitoring Gusseltjärnsdammen Siljansfors
PI: Ola Langvall
Ett avrinningsområde inom Siljansfors försökspark, innefattande Gusseltjärnen, har övervakats med flödesmätningar och kemiska vattenprovtagningar sedan 198?. Övervakningen initierades av Lars Lundin, SLU, Inst. för vatten och miljö, Uppsala. Numera görs övervakningen i försöksparkens egna regi. Vattenflödet mäts i Gusseltjärnsdammen med automatisk mätutrustning, medan vattenprover tas månadsvis, för kemiska analyser. A small watershed within Siljansfors Experimental Forest has been monitored since 198?. The monitoring was initiated by Lars Lundin at SLU, Dept. of water and environment in Uppsala. Nowadays the monitoring is run by the Experimental Forest. Water flow is monitored by automatic measurements and water samples for chemical analysis are taken monthly.
