The sedimentation datasets of Keuliling reservoir

Abstract

Sedimentation is commonly found as one of the problems affecting the function of reservoirs in Indonesia. High risk soil erosion leads to the increase in sediment production which negatively influencing the capacity or functional age of the reservoir. Generally, several reservoirs in Indonesia are experiencing the operational problem due to the increasing of sedimentation throughout the year. The data presented in this article was obtained from the measurement of sediment in the area of Keuliling reservoir, including: The data of suspended sediment at every Keulling reservoir water inlet, the data of bedload sediment at the bottom of the Keuliling reservoir, the hydrometric data, including the water velocity and channel profile, where the sampling of bedload and suspended sediment sampling was conducted at each inlet. the data sediment volume at the dam reservoir. The data of suspended and bedload sediment were obtained by taking the samples and analyzed in a laboratory. The measurement was conducted three times in five months. The data of water velocity was also generated based on the measurement using a currentmeter. Meanwhile, the sediment volume data in the water storage of reservoir was gathered by conducting a bathymetry and topographic survey at the dam reservoir location and then comparing it with the pre-existing bathymetry and topographic data.

Diagnóstico Batimétrico do Reservatório da Usina Hidrelétrica de Caçu-GO

“…Nos estudos realizados por Almeida, Figueiredo e Oliveira (2016) no reservatório de Itacarambi (Brasil), de Minhoni, Brito e Azevedo (2017) no reservatório da PCH Pipoca (Brasil) e por Armido et al (2020) no reservatório de Keuliling (Indonésia), foram verificados que, no trecho inicial do reservatório, ocorria a menor profundidade, com possibilidade de formação de bancos de areia, e próximo ao barramento, as maiores profundidades, com menores possibilidades de formação de bancos de areia, fato semelhante aos observados nesta pesquisa para o reservatório de Caçu.…”

An update on reservoir operating rules following changes on the effective capacity due to land erosion

“…Bathymetri process at Waduk Keuliling is carried out at Waduk Keuliling Area. The depth measurement of the Keuliling reservoir was performed using the ultrasonic wave reflection method which is perpendicularly emitted to the bottom of the water surface using the transducer (an echo sounder tool) and then the wave will be reflected back to the transducer [9].…”
