The hydraulics of stepped spillways with flat steps has been studied for the last three decades, including for embankment dam slopes, but studies of alternative stepped designs are limited. In this study, a pooled stepped spillway was investigated in a relatively large-size facility, and three different pool wall porosities were tested. The flow patterns, the macroand microscopic air-water flow...

Understanding the flow through porous media when it is part of geotechnical-hydraulic structures has been a scenario calculated from most unfavorable situation. The passage water skeleton soil considered in saturated condition. Few studies to date consider partially trajectories regarding influence on stability dam, reservoir, embankment, among others. Estimating speed with which fluid under an...

This paper explains how flood control is carried out in the Kali Lamong river basin area, Gresik Regency, to overcome disasters through construction of dams. To answer this question, uses policy implementation theory from Edwards III and a qualitative descriptive research method with data collection interviews, observation, documentation. Research shows that has been realized, both seen communi...

The compaction quality of embankment dams directly affects the safe operation power stations. traditional monitoring method has shortcomings limited sample and time consumption. Compaction can be reflected by compression ratio (CR) filling material. A novel based on unmanned aerial vehicle (UAV) photogrammetry technology, which rapidly acquire CR entire area, is proposed in present paper. Speci...
