The Transboundary Reach of the Columbia River: Cottonwood Colonization Followed Flow Moderation From the Columbia River Treaty Dams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The Columbia river provides the largest Pacific outflow in the Western Hemisphere and the greatest hydropower production of any North American river system. For hydropower generation and flood risk management, four massive water storage reservoirs followed the Columbia River Treaty between Canada and the United States, with three Canadian dams,

Soil modification in a chronosequence of postagricultural ecosystems of the intrazonal lithogenic matrix (Arkhangelsk region, Russia)

open access: yesActa Agrobotanica, 2019
Processes of soil self-restoration and soil modification in the chronosequence of postagricultural ecosystems located within the intrazonal (floodplain) soils of boreal forests were studied.

Vegetation, Ökosystemdynamik und Renaturierung von zentralasiatischen Flussauen am Beispiel des Tarim in Xinjiang, NW-China [PDF]

open access: yes, 2013
Naturally, the floodplains of Central Asian rivers harbour riparian, so-called ‘Tugai’ forests, reeds with Phragmites australis, and shrub communities which form a mosaic depending on the variety of available ground water.

The Age and Origin of the Gelderse IJssel [PDF]

open access: yes, 2008
Historic trading cities are located on the Gelderse IJssel and flourished in the late Middle Ages. Little is known about this river in the early Middle Ages and before, and there is considerable debate on the age and origin of the Gelderse IJssel as a ...

Injury Risks to a Migratory Freshwater Fish During Downstream Passage Through a Regulated Floodplain Outlet: A Case Study on Golden Perch (Macquaria ambigua)

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River infrastructures such as weirs, dams, inlet and outlet regulators often impair connectivity, leading to degradation and loss of key habitats for riverine fishes. This also holds true for golden perch (Macquaria ambigua Richardson), a migratory species in Australia's Murray–Darling Basin.

Patterns in the Use of a Restored California Floodplain by Native and Alien Fishes

open access: yesSan Francisco Estuary and Watershed Science, 2007
Fishes were sampled on the restored floodplain of the Cosumnes River in Central California in order to determine patterns of floodplain use. The floodplain was sampled for seven years (1998-2002, 2004-2005) during the winter-spring flooding season.

Temperature dependant generationcycle for the cicindelid beetle Pentacomia egregia CHAUD. (Coleoptera, Carabidae, Cicindelinae) of the Amazon valley

open access: yes, 1985
Experiments with the cicindelid beetle Pentacomia egregia, living in the floodplain forests of the Amazon river, indicate the temperature to induce the habitat change of the beetles and reproductive cycle of the ...

Floodplain environmental change during the younger dryas and holocene: Evidence from the lower kennet valley, south central England [PDF]

open access: yes, 2006
Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacial-interglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that
