The Krycklan Catchment Study (KCS) has become one of the most ambitious projects to integrate water quality, hydrology and aquatic ecology in running waters of the boreal region. KCS builds on three decades of catchment science that grew up around the hydrology and water chemistry monitoring on the 50 ha Nyänget catchment in the Svartberget Experimental Forest. The project expanded to the landscape scale in the winter of 2002/2003. At present the KCS includes 18 intensively instrumented and continuously monitored sub-catchments, another 90 stream sites that are sampled less frequently, an extensive soil sampling program, ecological studies, a "riparian observatory", several field experiments and a large set of ancillary data. These comprehensive and complementary sources of information make KCS a unique experimental field site in a boreal setting for catchment science.

The overall purpose of the KCS is to provide high quality field data to allow state-of-the-art progress towards understanding hydrological, biogeochemical and ecological functioning of running waters in the boreal region. The is to allow the development of a new generation of water management models and environmental guidelines that are based on high quality, high frequency and spatially distributed water chemistry and hydrological data. At present, KCS includes over 40 scientific projects spanning from fundamental scientific research to more applied studies, with participating scientists from over 10 countries in Europe and North America.
