Krycklans avrinningsområde

Krycklan är ett avrinningsområde i den boreala delen av norra Sverige, Västerbotten. Vattnet i Krycklan rinner ut i Vindelälven som börjar uppe bland fjällen, korsar Sverige och i sin tur rinner ut i Östersjön, nära Umeå. Området är en mosaik av myrar och sjöar spridda i ett skogslandskap. Avrinningsområdet innefattar, or är en del av Svartbergets försökspark.

Krycklans historia

Forskningen på hydrologi och biogeokemiska cykler började på 1980-talet i och med övervakningen av det 50 hektar stora upptagningsområdet Nyänget, som inleddes av Kaj Rosen och Harald Grip.

Under 1990-talet bidrog Nyänget till forskningen kring försurning av bäckar, och Kevin Bishop med kollegor öppnade upp för en ny syn på antropogen försurning och naturligt lågt pH i boreala avrinningsområden. Detta arbete har sedan dess lett fram till de nuvaranda riktlinjerna kring försurning i Sverige.

Med tiden expanderades forskningen för att även inkludera studier av kvicksilver, aluminium, erosion, kolcykler och vattenupptag hos träd. Mer intensivt arbete började även på kopplingen mellan jordar och ytvatten, vilket har lett till en mer processorienterad förståelse av bäckvattenkemi.

Ett annat fortfarande växande forskningsområde är påveran av klimat på bioeokemi och akvatisk ekologi, vilket har lett till expansionen från det ursprungliga 50 hektar stora avrinningsområdet (Nyänget) till det 6780 hektar stora Krycklan-avrinningsområdet. Denna expansion startade under vintern 2002/2003 då flera vattendrag nedanför nyänget lades till i provtagningsprogrammet som nu är uppe på regional landskapsskala. Ännu en bäck, lokaliserad på Degerö stormyr (Kulbäcksliden, utanför det huvudsakliga avrinningsområdet) inkluderades också i programmet.

Utöver detta så installerades automatiserad utrustning vid de olika vattendragen. Denna expansion har öppnat upp för möjligheter att vidare bredda både forskningsfrågor och funderingar kring vattenhantering. Frågor ställda av både myndigheter och forskare kan besvaras med hälp av den infrastruktur som nu finns i området.

Möjligheten att arbeta med Krycklan på landskapsskala tillåter oss att applicera miljöproblem och modeller som används för vattenförvaltning och skydd av akvatiska ekosystem. Det vore omöjligt att undersöka sådanna funderingar utan information från små provtagningsytor, sluttningar och vattenupptagningsområden. Från Nyänget finns det exempelvis snart 30 år av kontinueliga mätresultat från vattendrag.

Forskning

Flertalet professorer, forskare och docenter, samt nästan 20 doktoranter, tekniker, masterstudenter och fält-/labbassistenter arbetar dagligen inom Krycklan.

Forskningen som tar plats vid Krycklan värderar ett multidiciplinärt tillvägagångssätt, vilket inkluderar skalberoende aspekter men även bryggar gapet mellan avrinningsområden av olika storlek, tidsberoende variationer, varierande landskapsförhållanden och antropogena störningar av landskapet.

 

Huvudsakliga forskningsfrågor inom Krycklanprojektet:

  • Kopplingar mellan terrestra och akvatiska system.
  • Skalning från små till stora vattendrag.
  • Antropogena störningar.

Krycklan makes it possible to understand key processes then used for building and developing models working at different scales

Krycklanprojektet kan bedriva banbrytande forskning på grund av förmågan att använda denna unika forskningsplatform som spänner genom de traditionella disciplinära avgränsningarna, så väl som kopplingar till empiriska och experimentella resultat. Detta gör det möjligt att förstå processer som sedan används för att bygga upp och utveckla modeller som används på olika landskapsskalor. Vi har även möjligheten att komma förbi gapet mellan överparameterizerade mekaniska modeller och översimplifierade korrelativa tillvägagångssätt.
