A dam break is a low-probability, high risk catastrophe event that extremely destructive and has substantial negative socio-economic impact on downstream nearby areas. Simulating breach analyzing flood propagation from those events vital for identifying minimizing the risks associated of location. This study intended to anlayse effect overtopping failure two scenario (a) base-case (scenario wit...

Introduction: Cold temperatures on Mars [1] and a thin atmosphere prevent the occurrence of water in liquid form on the planet. However, sedimentary rocks at Meridiani Terrae show aqueous sedimentation. Catastrophic outgassing due to the Tharsis rise would result in increasing temperature and pressure, enabling water to exist on the surface for short periods of time. Magma–ice interactions duri...

Abstract Floods occur due to several factors including topographic conditions, high rainfall intensity, blockage of water flow, lack infiltration areas, deforestation, and so on. The Tojo watershed is included in the Parigi-Poso river area, with an area 211,830 km2 a length 25.52 km. In watershed, it necessary study flooding, because always flows every year. This research aims find out how much...

Abstract Armoring is forming an armor layer of the riverbed which preceded by transportation bed sediment. Mobile occurs when reaches equilibrium, then eroded, and surface recovers. Therefore, protection formed moving material. This research used a simulation model generated through HEC RAS software version 6.1. The input location was Krasak River, Sleman, Yogyakarta. data for were topography R...

In line with the North Lombok Regency (KLU) government program to prioritize handling and structuring residential areas disaster-prone in Pemenang-Tanjung sub-district 2022, it is necessary carry out several technical studies support program. One of that can be carried an analysis design flood river capacity around Sokong River section Tanjung Village, which a location classified as densely pop...

Hydrograph recession constants are required in rainfall-runoff models, base flow augmentation studies, geohydrologic investigations and in regional low-flow studies. The recession portion of a streamflow hydrograph is shown to be either an autoregressive process or an integrated moving average process, depending upon the structure of the assumed model errors. Six different estimators of the bas...

[Background] Mountain torrent disasters are one of the deadliest weather-related natural in world, often causing extremely serious economic and property losses casualties; recent years, due to heavy rainfall complex geological geomorphological conditions, mountain have occurred frequently Gansu Province. An effective rainfall-runoff model is key prevent them. There still many problems about how...

Considering characteristics of high river density, special underlying surface in plain river network region, and municipal drainage system function, river network drainage unit model is proposed, which is defined as a region surrounded by main river or embankment. Flood storage variety and control projects regulation of small rivers in each unit is simulated. With drainage catchment as an objec...
