Abstract Cisadane watershed is one of the priority watersheds to be restored immediately. The River has potency cause floods in river’s border region due a reduction river width, depth, and land-use changes. This study aims analyze distribution flood inundation by employing HEC-RAS. Flood modeling using components steady flow water level profile component. permanent use 19 January 2022 discharg...

Because of slight variation of the static head due to discharge fluctuations, the labyrinth weirs are considered to be economical structures for flood control and water level regulation in irrigation networks, as compared to other devices. Labyrinth weirs are composed of folded sections observed as trapezoidal and triangular in plan view. In this study, rectangular and U-shaped labyrinth weirs ...

The methodology for flood detection developed at Dartmouth Flood Observatory (DFO) (Brakenridge and others, 2007) on a global scale, was implemented at the Joint Research Centre (JRC) of the European Commission on an automatic operational basis. The technique is using AMSR-E passive microwave remote sensing data of the descending orbit, H polarization, 36 GHz band to detect flood events from sp...

This article examines the role of climatic and hydrological variability in assessing the cumulative risk of flood events in Poland over a T-year period. In a broad sense flood-risk estimation combines a frequency analysis of extreme hydrological phenomena with an evaluation of flood-induced damages. The damage from floods depends on the critical values of the river discharges. The probabilistic...

Flood-control levees are generally thought to increase flood height and velocity for a given discharge. While extensive areas of floodplain in the United States are leveed, the ecological impacts of levees have largely been ignored relative to other anthropogenic impacts to large river floodplains. We examined a century of flood control along the Wisconsin River by comparing simulated flood reg...

Eroded sediments from catchment areas transport by streams and deposit in downstream less steep areas. Despite reducing the useful life of various hydraulic structures including reservoir dams, flood walls, and bridges, this phenomenon changes the main river hydraulic conditions and increases the flood prone farms in the riverbank area. Check dams are among the structures that can prevent form ...

A dataset of 21 study reaches in the Porter and Kowai rivers (eastern side of the South Island), and 13 study reaches in Camp Creek and adjacent catchments (western side of the South Island) was used to examine downstream hydraulic geometry of mountain streams in New Zealand. Streams in the eastern and western regions both exhibit well-developed downstream hydraulic geometry, as indicated by st...

To reduce flood damage in the face of increasing frequency and intensity extreme rainfall events, it is necessary to implement linkages between hazard countermeasures resilient community development. This paper introduces an example analysis climate change impact on discharge Japan discusses predictions risk assessment for flood-resistant regional
