Map of the catchment area
Climatic conditions in the lower Vauz catchment

Contents

Location

  • Central-eastern Italian Alps
  • 46° 29' 31.98" N 11° 50' 25.85" E

Catchment size

1.9 km², with elevation range of 1,835 – 3,152 m and an avarage slope of 34.3 °

Climate

  • alpine humid climate
  • mean annual rainfall of about 1220 mm, 49% of which falls as snow
  • precipitation monthly distribution shows a peak in early summer and a second one during fall
  • in the lower parts of the catchment the snow cover period typically lasts from November to April. Runoff is usually dominated by snowmelt in May and June but summer and early autumn floods represent an important contribution to the flow regime. The average monthly temperature in the lower Vauz varies from 5.7 °C in January to 14.1 °C in July

Geology

  • consist of dolomite that supports subvertical cliffs

Vegetation/Land use

The basin is almost undisturbed by human activity: neither roads nor urban areas are present. The soil is primarily vegetated with grass (mainly of herbaceous associations), with root zone depth around 20 cm. Sparse woody vegetation (mainly larch) is distributed on a few hillslopes in the lower portion of the catchment.
