On tropospheric rivers
… procedure for identifying and tracking these rivers (named TRICKS, i.e., the Tropospheric River Identifying and traCKing Scheme) is described and its performance is evaluated. This procedure enables the maxima of moisture flux (so-called TR cores) to be detected and accurately located. The …

Non-cohesive bank migration in meandering rivers and bank accretion in weakly braided rivers
… the dissertation is the migration of meandering rivers whose banks consist wholly, or partly, of non-cohesive bed-material-sized alluvial deposits; such banks are known as composite banks when the near-surface layers consist of fine-grained deposits. The relevant forces and environmental …

Emergent geometries of groundwater-fed rivers
Groundwater-fed rivers form stunning geometries over a range of scales. These rivers grow as water from an underground aquifer reemerges and erodes the overlying topography. Both the aquifer and the overlying topography generate flows along diffusive gradients. We study three features produced by …

Classifying Single-thread Rivers: A European perspective
… of ‘near-natural’ European single-thread rivers, which are free to adjust to fluvial processes. The research involves subdividing rivers along a continuum of geomorphological characteristics to assign river reaches to geomorphologically-meaningful classes according to their channel …

Morphodynamics and driftwood dispersal in braided rivers
… few studies focus on driftwood in large braided rivers and limited quantitative information is available on wood transport, deposition and remobilisation in these systems. The goals of the present work are: a) characterising the spatial organisation of wood deposits and identifying typical …

Improved predictions of contaminant transport in rivers
… improve predictions of contaminant transport in rivers, two analytical models and one empirical model were evaluated. Analytical solutions of the model of Reichert and Wanner (1991), which represents mixing in the advective zone by dividing the channel into a flowing zone and a stagnant zone, …

Providing a Restoration Framework for Regulated Rivers
… proposed, successful restoration of regulated rivers will depend on the creation of broadly applicable frameworks that provide management solutions by generalizing patterns in habitat and ecology. Based on the prevailing scientific literature, restoring natural stream flows in disturbed rivers …

Governance of International Rivers: Threats, Gaps and Challenges
… looks at issues of governance of international rivers in terms of threats to them, gaps in their governance regimes and challenges associated with closing those gaps. International river basins globally are currently threatened with over-extraction, pollution, damming and infrastructural …

Interaction among vegetation and morphology in channelized rivers
… besides the general impacts of vegetation in rivers. Isolated patches of vegetation are more common in practical applications rather than uniform vegetated channels in which the mean properties of the vegetation canopy are independent of the location. The present study considered the changes …

Hydropeaking in Alpine rivers: an ecosystem services approach
Rivers provide to society many important goods and benefits. Some of these ecosystem services depend on the river flow regime, which has been deeply modified by human structures and activities. These alterations have a direct influence on biodiversity, natural habitat and on the supply of river …

Holocene Geomorphology of the Macdonald and Tuross Rivers
… to examine how the floodplains of these coastal rivers have responded to such base level changes and also to the variable Holocene climate. From 9000 to 6000 years BP, as sea level was rising to its Holocene maximum, aggradation occurred in the alluvial reaches of both the Tuross and Macdonald …

Optical Water Quality and Human Perceptions of Rivers
… water quality dynamics in recreational rivers is integral in shaping management strategies that maintain ecosystem health, perceived value and appeal, and regional economic significance in a changing environment. Optical water quality describes the behavior of light in water as governed …

Vertical Velocity Distributions in Sand -Bed Alluvial Rivers
Shear partition models of Einstein and Nelson-Smith were evaluated with the field data collected in this research. Einstein's method had an absolute average percent error of 11.3%, while the Nelson-Smith method had an absolute average percent error of 22.2% when the smaller bedforms were used as …

Hydrologic sensitivities of western U.S. rivers to climate change
… climate information to easily assess underlying drivers of change and to bound, at least approximately, the range of future streamflow uncertainties for water resource planners.

Numerical Modelling of Braiding Processes in Gravel-Bed Rivers
Gravel-bed braided rivers are distinctive natural environments that provid a wide range of key environmental, economic and recreational services. There is, however,a growing concern that over the twentieth century, an increasing number of braided rivers have metamorphosed into wandering or single …
