Abstract:
... The temporal shoreline position is a key indicator of coastal development and provides information on beach dynamics. Previous studies have indicated that there is a strong relationship between riverine sediment fluxes and beach volume. As such, worldwide hydroelectric projects and the associated damming infrastructure have decreased suspended sediment loads, and consequently increasing coastal er ...

Abstract:
... Flip bucket is one of the energy dissipaters which passes over flow through the dam and is used for injecting the flow to the plunge pool. Impact of the water jet with river leads bed elevation to change and it not only threatens the stability of dam, but also influences the river in downstream. Experimental studies include record of changes in bed elevation in plunge pool of the Kheirabad dam in ...

... Early seral vegetation was studied on a former lake bottom after the removal of the 64‐m‐tall Glines Canyon Dam on the Elwha River. In 2015, vegetation cover of all vascular plant species was determined in 63 plots located on sites that emerged in 2011–2012. The sites had been planted and/or seeded, or were permitted to revegetate spontaneously. The plots were further classified by substrate textu ...

Abstract:
... Large‐scale flow release experiments are becoming common for improving aquatic habitat quality downstream of dams. Because of the naturally high fine sediment load in the Durance River, France due to inputs from torrential tributaries draining badlands, unpredictable high flow events with dam overspill are not always sufficient to prevent clogging, which can lead to habitat degradation (especially ...

Abstract:
... Natural and manmade disasters have occurred more frequently due mainly to climate change and human pressure for productivity. One of the world's vastest disasters in the mining industry occurred due to the collapse of the Fundao dam, Brazil, which discharged about 43 million m3 of iron tailings at the Doce River basin. Extreme natural events also affect this region and provoke substantial mass mov ...

As more attention is paid to microplastics, an emerging contaminant in waterways worldwide, and how they move along rivers, whether microplastic particles also accumulate behind dams is an important question for informing estimates of global river inputs to oceans. In this study, we ...

The occurrence of Holocene changes in the South American Summer Monsoon (SASM) in the Peruvian Andes has been well established in paleoclimatological records such as speleothem, lake and glacier records. How river systems responded to these events has, however, hardly been investigated. Here, we present evidence based on sedimentological, stratigraphical and geomorphological data as well as radiom ...
