Prosjektet ble finansiert av Norges Forskningsråd, under programmet Grunnleggende Energiforskning. Tidsrammen for prosjektet var to år, fra 1997 til 1999. Arbeidet ble utført av Nils Reidar B. Olsen som et post. doc. studium ved Institutt for Vassbygging, NTNU, med Prof. Dagfinn K. Lysne som prosjektansvarlig. Prosjektets ramme var i underkant av 1 mill. kr.
Animasjonen viser turbiditeten i Mjøsa under flommen i 1995. Rødt er høy turbiditet, mens blått er lav turbiditet. Gridflatene langs vannoverflaten og bunnen er vist, samt et lengdesnitt. Figuren viser at det forurensede vannet holder seg langs overflaten. Årsaken er temperatursjiktningen i innsjøen. Drikkevannsinntakene som ligger på dypt vann blir derved mindre berørt.
