Phreatic seepage flow through an earth dam with an impeding strip [PDF]
New mathematical models are developed and corresponding boundary value problems are analytically and numerically solved for Darcian flows in earth (rock)–filled dams, which have a vertical impermeable barrier on the downstream slope.

Abstract Addressing the limitations of traditional overtopping risk analysis methods, which either consider only a single failure mode or fail to accurately characterize the nonlinear characteristics of reservoir levels, this paper proposes a novel overtopping risk model for dams.

EFFECTIVE SEDIMENT CONTROL IN A RESERVOIR [PDF]
Sedimentation in a reservoir cannot be avoided. The average rate of sedimentation on the storage volume reduction of a reservoir in the world is about 1 % per year (Yoon,1992), meanwhile, the storage volume reduction in several reservoir in Indonesia ...

Air entrainment and splash characteristics in jet flows: Effect of downstream water levels
Abstract This study investigates the air–water interaction dynamics in jet streams, with particular emphasis on the transition from the cavity to the far‐field regions. A dual‐tip conductivity phase‐detection probe was employed to analyze four distinct downstream water levels.

Seepage Safety of a Rockfill-based Earth Dam Heightening Project [PDF]
[Objective] A large number of aging earth and rockfill dams in China needs to be heightened due to seepage risks and insufficient flood control capacity.

A methodology for the design of dam spillways with wedge shaped blocks based on numerical modeling [PDF]
Wedge shaped blocks spillways are an innovative solution that allows spilling over the downstream shoulder of earth and rock-fill dams in a safe way. However, they have been barely used as main spillway due to the lack of practical design criteria.

Abstract Underpinned by the ultrahigh‐core rockfill dam at the Nuozhadu Hydropower Station, comprehensive studies and engineering practices have been conducted to address several critical challenges: coordination of seepage deformation in dam materials, prevention and control of high‐water‐pressure seepage failure, static and dynamic deformation ...
