17 Ιουλ 2024 · Examining 20,045 samples from 136 perennial rivers and 45 large catchments globally, we categorized dynamic water retention as high, moderate or low.
16 Σεπ 2019 · However, compared to the other three main climate zones (Tropical, Temperate and Cold), the NCI values for Arid zone rivers are notably closer to zero (straighter) with a narrower...
16 Αυγ 2022 · The relationships between climate parameters and river width IQR suggest that regions with extreme climate conditions (e.g., extremely dry, cold, or hot) are more likely to show a high river width variability. We found that river width IQR increases with flow intermittence and discharge variability for most natural rivers (Figure 5B). This ...
22 Αυγ 2024 · This study examines biodiversity across 84 non-perennial rivers in 19 countries using DNA metabarcoding.
1 Φεβ 2018 · Rivers and streams that dry up are found on every continent, and can form a large proportion of river networks. When rivers are dry, traditional indicators of river health – such as aquatic macroinvertebrates, fish or water quality – cannot be measured.
4 Μαΐ 2021 · Intermittent rivers and ephemeral streams (IRES) are now recognized to support specific freshwater biodiversity and ecosystem services and represent approximately half of the global river network, a fraction that is likely to increase in the context of global changes.
1 Αυγ 2020 · This article presents a review of the current knowledge on bank erosion in rivers located in cold environments, providing consistent information on processes (terrestrial vs. fluvial), mechanisms (mechanical vs. thermal erosion), spatial and temporal variations, environmental controlling factors (hydraulic vs. non-hydraulic), and bankforms in ...
