15 Οκτ 2018 · Scatterplot of streambed gradient (J) vs meander wavelength (λ) of EMS compared to perennial rivers (data from Schumm, 1968 and Dury, 1976). The correlation is significant at α = 0.05 for EMS: p < 0.001; n = 107; but not for perennial rivers: p = 0.27: n = 43.
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.
By mining a new temperature database composed of >23,000 site records that spans the western United States (U.S.), we extract annual monitoring records at 578 sites on perennial streams to describe regimes in this diverse region.
22 Αυγ 2022 · Data Availability Statement. Go to: Abstract. Changes in a river's width reflect natural and anthropogenic impacts on local and upstream/downstream hydraulic and hydrologic processes. Temporal variation of river width also impacts biogeochemical exchange and reflects geomorphologic evolution.
1 Ιουλ 2017 · Environmental Science. Oikos. Comprehensive knowledge of the effects of disturbances on biodiversity is crucial for conservation and management, not least because ecosystems with low biodiversity may be the most vulnerable. In rivers, the role of disturbance in shaping aquatic biodiversity has mainly focused on floods.
A detailed analysis of flow patterns was performed on 12 rivers of the Guadiana Basin in Southern Iberia (10 in Spain and 2 in Portugal). An open methodology that can allow managers to better characterize and improve the structure and functioning of those rivers is suggested.
