River-floodplain interactions: nutrient concentrations in the Lower Paraná River [PDF]

Fundamental and Applied Limnology, 1998
Changes in water chemistry along the lower 500 km stretch of the Parana River were assessed. The water composition of the river and of a representative floodplain marsh were compared. Short-term changes in nutrient concentrations were monitored in marsh enclosures filled with river water in order to simulate the nutrient dynamics under floodplain ...

Application of 137Cs tracer technique in floodplain deposition research in mesoscale river basins

Geoderma, 2023
Floodplain deposition can provide important historical information about river systems. 137Cs tracer measurement is the most widely used technique for studying floodplain deposition.

Geological structure as a control on floodplain groundwater dynamics [PDF]

, 2018
Groundwater in upland floodplains has an important function in regulating river flows and controlling the coupling of hillslope runoff with rivers, with complex interaction between surface waters and groundwaters throughout floodplain width and depth ...

River-floodplain connectivity and residence times controlled by topographic bluffs along a backwater transition

Frontiers in Water
The morphology of river levees and floodplains is an important control on river-floodplain connectivity within a river system under sub-bankfull conditions, and this morphology changes as a river approaches the coast due to backwater influence ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Analyzing the discharge regime of a large tropical river through remote sensing, ground-based climatic data, and modeling [PDF]

, 1996
This study demonstrates the potential for applying passive microwave satellite sensor data to infer the discharge dynamics of large river systems using the main stem Amazon as a test case.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Spatial Expansion of Human Settlement during the Longshan Period (~4.5–~3.9 ka BP) and Its Hydroclimatic Contexts in the Lower Yellow River Floodplain, Eastern China

Land, 2021
Obvious spatial expansion of human settlement occurred in the lower Yellow River floodplain during the Longshan period, but the external factors driving this expansion remain unclear.
