TLDR
In this article, the effects that occurred upstream of the Cantillana Dam along the lower Guadalquivir River were investigated using geomorphological mapping, multitemporal analysis of aerial photos, topographic survey comparison of the channel bed, and archives of information concerning flood events.About:

Effects of South-to-North Water Diversion Project Cascade Dams on Riparian Vegetation Along the Middle and Lower Reaches of the Hanjiang River, China
TL;DR: In this article , the authors examined riparian vegetation types upstream and downstream from dams and found that the construction of cascade dams led to the differentiation of vegetation types downstream and upstream of the dam, and the riparian habitats were fragmented by these dams.

Upstream and Downstream Changes in the Channel Width and Sinuosity Due to Dam Construction in Tropical Rivers: The Case of Colombia
TL;DR: In this article , the impact of dam construction on river morphology was investigated by using aerial photographs and satellite images to compare the river before and after dam construction, and it was shown that factors such as valley confinement and the bank's composition are key to determining the magnitude of the impact downstream of the dam.

Methodological Framework for Assessing Hydromorphological Conditions of Heavily Modified and Artificial River Water Bodies in Croatia
TL;DR: In this paper , the authors presented the first assessment of hydromorphological conditions of HMWBs and AWBs in Croatia based on type-specific indicators, which were graded from the theoretical maximum and good ecological potential.

Flood-Rings Production Modulated by River Regulation in Eastern Boreal Canada.
Alexandre Florent Nolin,Alexandre Florent Nolin,Alexandre Florent Nolin,Jacques C. Tardif,Jacques C. Tardif,Yves Bergeron,Yves Bergeron +6 more
TL;DR: In this paper, the effect of regulation on the flood-ring occurrence (visual intensity and relative frequency) and on ring widths in Fraxinus nigra trees growing at five sites distributed along the Driftwood River floodplain was analyzed.

Downstream effects of dams on alluvial rivers.
G.P. Williams,M.G. Wolman +1 more
TL;DR: In this paper, the authors describe changes in mean channel-bed elevation, channel width, bed-material sizes, vegetation, water discharges, and sediment loads downstream from 21 dams constructed on alluvial rivers.

Impounded Rivers: Perspectives for Ecological Management
TL;DR: In this paper, a comprehensive geographic analysis of the impact of dams and their associated reservoirs on rivers is presented, focusing on the river system downstream from the dam, including its floodplain, estuary or delta, and the near-shore coastal zone.
Journal ArticleDOI
Classification of geomorphological effects downstream of dams
TL;DR: In this paper, the effects of dams on downstream geomorphology are reviewed and a typology is devised, consisting of nine cases, which can be seen as a further development of Lane's balance between water discharge, sediment load, grain size, and river slope.

Sustainable sediment management in reservoirs and regulated rivers: Experiences from five continents
G. Mathias Kondolf,Y. Gao,George W. Annandale,Gregory L. Morris,Enhui Jiang,Junhua Zhang,Yongtao Cao,Paul A. Carling,Kaidao Fu,Qingchao Guo,Rollin H. Hotchkiss,Christophe Peteuil,Tetsuya Sumi,Hsiao-Wen Wang,Wang Zhongmei,Zhilin Wei,Baosheng Wu,Caiping Wu,Chih Ted Yang +18 more
TL;DR: In this article, the authors summarized collective experience from five continents in managing reservoir sediments and mitigating downstream sediment starvation, and recommended that these sediment management approaches be utilized where possible to sustain reservoir capacity and minimize environmental impacts of dams.

Economics of reservoir sedimentation and sustainable management of dams
TL;DR: A framework for assessing the economic feasibility of sediment management strategies that would allow the life of dams to be prolonged indefinitely is provided and sustainable management of reservoirs is economically more desirable than the prevailing practice of forcing a finite reservoir life through excessive sediment accumulation.
