Understanding how catchment streamflow response varies in time and at different spatial scales is critical to assess runoff production and water availability in mountain areas. In this research, we studied streamflow response in three Dolomitic nested catchments (0.14÷109 km2) to i) relate streamflow response variability with spatial scale, and ii) identify the main controls for such variability. Results show that specifc streamflow and runoff coefcient usually decrease with the increasing spatial scale, but snowmelt contribution to streamflow can be relevant for catchments characterized by large fraction of high-elevation areas. The multiple regression analysis explains up to 0.81 of the variability of streamflow response, where event precipitation and storm duration are the most important predictors of the hydrological response in the three catchments.

Abstract

Understanding how catchment streamflow response varies in time and at different spatial scales is critical to assess runoff production and water availability in mountain areas. In this research, we studied streamflow response in three Dolomitic nested catchments (0.14÷109 km2) to i) relate streamflow response variability with spatial scale, and ii) identify the main controls for such variability. Results show that specifc streamflow and runoff coefcient usually decrease with the increasing spatial scale, but snowmelt contribution to streamflow can be relevant for catchments characterized by large fraction of high-elevation areas. The multiple regression analysis explains up to 0.81 of the variability of streamflow response, where event precipitation and storm duration are the most important predictors of the hydrological response in the three catchments.
