Texture effect<br />
Inter-annual (period 1996–2003 shown in Figs. 4-5)<br />
monitoring demonstrated that variation in unfrozen<br />
soil water content <strong>of</strong> tills followed climatic events,<br />
but snowmelt was the major contributor to the intra-seasonal<br />
ε TIL . The increase in ε TIL was initiated<br />
by meltwater released from the snowpack over two<br />
weeks to more than three weeks before the snow<br />
disappearance in both cases. However, the response<br />
<strong>of</strong> snowmelt to the ε TIL was clearly site and texturespeci<strong>fi</strong><br />
c, such that the intra- and inter-seasonal soil<br />
ε TILL was signi<strong>fi</strong> cantly lower (F=810, p=0) in sandy<br />
till than in silty till. Even the maximum soil water<br />
content at Juolkusselkä site was minor to that <strong>of</strong> the<br />
minimum at the Vaalolehto site. It was found that<br />
mean inter-seasonal ε TIL =7.0±1.36 applies to sandy<br />
till and v=24.4±6.56 to silty till, respectively. We<br />
estimated (99% con<strong>fi</strong> dence) that the inter-seasonal<br />
mean <strong>of</strong> sandy till varies between 6.7< ε TIL
