Sand Pocket which located at Jeneberang river is one of the river structure to control sediment flow towards the dam. Bili-bili dam face a huge sedimentation problem in 2004 caused by the collaps of mount Bawakareng gigantic caldera as the upstream of Jeneberang river.which brings about 80.5 million cubic of sediment, and estimated that …

Recent studies have revealed the existential threat of anthropogenic accelerated subsidence ... In case of the implementation of a sedimentation strategy, the new sediments will increase the ...

This study provides the first large-scale evaluation of satellite-based estimates of reservoir sedimentation rates and offers insights into the feasibility of combining Sentinel-2 images with satellite altimeters for reservoir sedimentation studies when in-situ water levels are not available. ... Finally, we estimated the sediment volume …

The results show that: (1) Under the new conditions of water and sediment, the amount of sediment in the TGR accounts for only 14.8% and 35.8% of that in …

From different angles, the study reported in this paper is pertinent as it addresses the subject of reservoir sedimentation which is a general concern for freshwater sustainability. In fact, the phenomenon of sedimentation is a common problem for reservoirs and lakes management due to its complexity but also to the environmental …

The sediment thickness data are summarized in Table 1. Sediment thickness ranged from 10 cm in the northwest arm of the lake to 74 cm at the west side of the south basin. Sediment thickness in the central part of both the south and north basins was consistently between 65 and 74 cm thick.

Suddenly a sharp decline of sedimentation rate from 1 to 0.96 ± 0.09 cm/year infers slow rate of sediment supply and deposition happened from 1989 to 1996AD may be due to unfavorable climatic conditions in the study lake, which makes the sedimentation process slow so that it took nearly 7 year to deposit only 4 cm of sediments. After …

The present study was designed to determine the combined effect of two significant parameters (sediment concentration and water salinity) on the sedimentation processes of mud particles. The experimental investigations indicate that the settlement height of settling particles increases with increasing initial sediment content.

Lago Loíza impounded in 1953 to supply San Juan, Puerto Rico, with drinking water; by 1994, it had lost 47% of its capacity. To characterize sedimentation in Lago Loíza, a study combining land ...

Rates of sedimentation are measured in three main contexts. The first is the study of sedimentation systems that are active today; the second is what has come to …

Globally, water and energy demands are increasing continuously, while the storage capacity of structures like dams and reservoirs is reducing due to sediment-induced problems. Study of the reservoir sedimentation is essential for restoring the storage capacities to ensure the increasing water and energy demands. This study …

Studies presenting four (6 papers) or five (2 papers) distinct measurements were particularly scarce in the literature. Overall, studies into reef sediments generally quantify a small subset of reservoirs and processes in isolation from other measurements. 3.2. Sedimentation, remobilisation, and accumulation

Background Management actions that address local-scale stressors on coral reefs can rapidly improve water quality and reef ecosystem condition. In response to reef managers who need actionable thresholds for coastal runoff and dredging, we conducted a systematic review and meta-analysis of experimental studies that explore the effects of …

With the global population reaching 7.8 billion by 2020, at a 1% annual rate of increase (Worldometer 2023), it is clear that urban expansion is necessary. Urban development surrounding reservoir catchment areas has reduced vegetation coverage and consequently increased the … See more

From the study, it was found that due to sedimentation, the live storage capacity of Patratu Reservoir has reduced from 101.95 to 89.96 hm3, thus showing capacity loss of 11.76% in span of 44 years.

Himalayan regions have increasing sediment yield due to undulating topography, slope and improper watershed management. However, due to limited observation data, and site accessibility issues, less studies have quantified sedimentation loads in the Himalayas, especially Nepal. This has hindered the investments on run-of-river hydropower projects …

USACE adaptation pilots identified altered reservoir sedimentation rates that result from a changing climate and land use change as a critical area for agency missions and operations. USACE is the largest operator of dams in the United States. Each USACE dam was planned, designed and built to provide specific benefits to the American public ...
