Banjir merupakan masalah yang rutin dialami oleh masyarakat di wilayah Sungai Kali Lamong, khususnya Desa Jono dan Tambakberas, Kecamatan Cerme, Kabupaten Gresik. Oleh sebab itu untuk mengurangi banjir, diperlukan pembangunan tanggul. Akan tetapi, tanggul memerlukan adanya pengadaan tanah pada lokasi direncanakan. Tujuan dari studi ini adalah melakukan analisa banjir dengan program HEC-RAS, kel...

Abstract Flood catastrophe continuously hit Malaysia through monsoonal flood and flash as well posing threat towards people, infrastructure environment. Batu Pahat is among the district in Johor affected by disaster for almost every year. This study conducted to determine hydraulic hydrological characteristic ability of drainage system Parit Besar Jalan Pontian-Batu catchment area at using HEC-...

Measures should be taken to make better use of the rivers in the study, construction and exploitation optimized to contain, mitigate risks and minimize the negative consequences and the improvement of the situation in order to meet human needs and protect the environment there. Route investigated in Khorasan Razavi province and city and river Ghochan is Atrak. Physiographic parameters using dig...

In terms of engineering standards, the dimensions hydraulic structures such as culverts on forest roads should have capability to drain expected maximum discharge for a 50-year return period during their lifespan (i.e., 20 years). Turkey, Talbot’s formula, empirical method, has commonly been used in determining required cross-sectional area (CSA) structures. However, practice, road engineers Tu...

Abstract. The changing climate and anthropogenic activities raise the likelihood of damage due to compound flood hazards, triggered by combined occurrence extreme precipitation storm surge during high tides exacerbated sea-level rise (SLR). Risk estimates associated with these event scenarios are expected be significantly higher than derived from a standard evaluation individual hazards. In thi...

River renaturation can be an effective management method for restoring a floodplain’s natural capacity and minimizing the effects during high flow periods. A 1D-2D Hydrologic Engineering Center–River Analysis System (HEC-RAS) model, in which flood plain was considered as 2D main channel 1D, used to simulate flooding restored reach of Spree River, Germany. When computing this finite volume diffe...
