Abstract (sommario):

This article delineates the idea of an Indigenous hydropoetics as an ancestral outlook on rivers grounded in Aboriginal cultural traditions of, and everyday interactions with, rivers. In particular, two features—embodiment and relationality—prove integral to conceptualising Indigenous hydropoetics in response to the hydrological precarities of the present. Recognising rivers' capacity for agency, the idea is developed in relation to contemporary Aboriginal Australian poetry narrating long-standing human interdependencies with rivers.

Abstract (sommario):

The geological diversity of the Amazon Basin, as well as the pluvial regime, influences the characteristics of the waters. To know the water types of the rivers of the Amazon basin, 288 superficial water samples were collected, 94 of them along the Amazon River and 194 in their tributaries, from March 2009 to September 2012. The physical, chemical, and physicochemical properties were analyzed. Rivers with pH between 6.5 and 7.6 and electrical conductivity (40.00 - 80.00 μS cm-1) are water bodies that are influenced by the Andean region (e.g., the Amazon River and some of its right bank tributa

These measurements were performed by vectorising river channels from a topographic map at a scale of 1:25,000. Contemporary orthophoto maps were used as additional cartographic sources for verification. The approaches used to determine the starting and ending points of rivers, i.e. sources and mouths or confluences, have been explained and their spatial coordinates were listed. The results showed that in terms of total river length, the 21 river

Abstract (sommario):

Water qualities of three suburban rivers, namely, Kuantan, Belat, and Galing rivers, in Kuantan, Malaysia, were examined effectively by using ion-exclusion/cation-exchange chromatography with water quality indices and land usage data. Specifically, we have focused on evaluating and grasping the effect of sewage/household wastewater discharged from housing areas in the Kuantan district on the river water quality. Based on this study, the following beneficial information were obtained effectively: (1) the pollution levels in the three rivers (Kuantan River: Classes I–III, Belat River: Classes I–

Abstract (sommario):

Seasonal nutrient dynamics were investigated in four rivers with a microtidal range (Terekhol, Chapora, Sal and Talpona rivers) and were compared with those of two rivers with a mesotidal range (Zuari and Mandovi rivers) along the central west coast of India. Rainfall and freshwater discharge during the wet season led to salinity stratification of the water columns at the mouths of these rivers. Nutrient concentrations in all rivers were higher during the wet season than in the dry season due to considerable land run-off. Based on the estuarine mixing diagrams of the nutrients with regard to s

The High Court Division of the Supreme Court of Bangladesh has declared the rivers of Bangladesh to be legal persons and has appointed the National River Conservation Commission (NRCC) as the legal guardian of rivers for protecting the rivers of Bangladesh. The court considered the importance of rivers to Bangladesh, the public trust doctrine, the current global trend of granting rights to natural entities and the pressing need for an alternative option for river protection. However, on the one hand, the court has not clearly articulated any aspects of the legal personhood of the rivers; while

Abstract (sommario):

Australian tropical rivers are dependent on highly seasonal rainfall and runoff between November and April. They also transport low sediment and solute loads, except where catchments have been disturbed by mining, grazing and cropping. Aquatic habitats or channel units are the physical template influencing fish communities. Pools provide dry-season refuges for fish and channels provide pathways for movement between refuges when streamflows are re-established. A preliminary geomorphological typology of Australian tropical river reaches (excludes estuaries) is proposed that defines nine distinct

Abstract (sommario):

Human activities have been affecting rivers and other natural systems for millennia. Anthropogenic changes to rivers over the last few centuries led to the accelerating state of decline of coastal and estuarine regions globally. Urban rivers are parts of larger catchment ecosystems, which in turn form parts of wider nested, interconnected systems. Accurate modelling of urban rivers may not be possible because of the complex multisystem interactions operating concurrently and over different spatial and temporal scales. This paper overviews urban river syndrome, the accelerating deterioration of

The article examines thermal parameters of rivers during climate warming, focusing on quasi-natural rivers and those heavily impacted by humans. It compares two periods (1961-1992 and 1993-2020) based on daily water temperatures. Results show rivers warmed by 0.7-1.0°C in the second period, except those strongly polluted, like the Przemsza River, which cooled by up to -1.2°C. In quasi-natural rivers, the largest temperature rise occurred in spring (up to 3.5°C). In contrast, heavily impacted rivers showed lower, often negative changes.

Models of river plankton frequently suggest that these passively drifting communities are limited to downstream sections of larger rivers. I examine this hypothesis using a passive drift model for populations in advective environments, followed by a comparison of predicted and observed plankton populations in rivers. Under the scenario of continuous downstream drift, much of the plankton found in rivers is not predicted to occur. However, much of the observed plankton in rivers is explained through the addition of cross-channel flow heterogeneity to the model. Empirical data support the model

Research on urban rivers often seeks to find commonalities to advance knowledge of the effect of urbanisation on rivers, and rightly so. But it is important, also, to develop a complementary understanding of how urban rivers can be distinct, to facilitate a more nuanced view of concepts such as the ‘urban river syndrome’ and of the challenges facing those who wish to create more sustainable urban river corridors. To this end we use the Don Catchment as a case study to illustrate how historic patterns of urbanisation have been fundamental in shaping the catchment’s rivers. Following the Industr
