Wood storage in three mountain streams of the Southern Andes and its hydro‐morphological effects
Abstract This study analyses large wood (LW) storage and the associated effects on channel morphology and flow hydraulics in three third‐order mountain basins (drainage area 9–12 km 2 ) covered in old‐growth Nothofagus forests, ranging from the temperate warm Chilean Andean Cordillera to the sub‐Ant...
