Use of high-intensity data to define large river management units: A case study on the lower Waikato River, New Zealand [PDF]

open access: yes, 2014
The importance of environmental heterogeneity in lotic ecosystems is well recognised in river management, and continues to underpin studies of hierarchical patch dynamics, geomorphology and landscape ecology. We evaluated how physical characteristics and

Experimental reintroduction of woody debris on the Williams River, NSW: geomorphic and ecological responses [PDF]

open access: yes, 2004
A total of 436 logs were used to create 20 engineered log jams (ELJs) in a 1.1 km reach of the Williams River, NSW, Australia, a gravel-bed river that has been desnagged and had most of its riparian vegetation removed over the last 200 years.

Preliminary assesment of variability of Suspended load changes in cross-section Chalupki on Odra River

open access: yesActa Scientiarum Polonorum. Formatio Circumiectus, 2020
Aim of the study: The aim of the study was to analyse the reasons for the occurrence of intensive suspended load transport in the area of meander 1. The river load transport caused significant morphological changes in the Upper Oder River bed system.
