flood routing in rivers is a mathematical procedure to determine flow hydrograph at a point in a river. one of routing methods is based on solution of saint-venant equations for unsteady flows. because this method is very complex and need to more information of river, other methods with simple calculations and reasonably accurate results have been extended and give generally satisfactory result...

Extreme hydro-meteorological phenomena have become more frequent in recent years compared to the year 2000 Europe, including Romania. Flooding occurs from heavy rainfalls favored by natural and anthropogenic factors such as valley’s flat slope or settlements situated near river. Ţigăneşti Brânceni villages (from southern Romania) are no exception been affected floods many times. One of these ev...

This study is concerned with unsteady flow in open channels boundary conditions that may exist river or channel system. A software Hydrologic Engineering Center-River Analysis System (HEC-RAS) was used for a case study. The contains hydrodynamic model simulating the based on one-dimensional form of Saint-Venant equations, by formulating discrete using implicit finite difference scheme, then sol...

Most flood inundation models do not come with an uncertainty analysis component chiefly because of the complexity associated model calibration. Additionally, fact that are both data- and compute-intensive, since results from multiple sources, adds another layer for use. In present study, modeling was performed in Godavari River Basin using Hydrologic Engineering Center—River Analysis System 2D ...

communicative moves and lexical cohesion patterns (lcps), as mounting evidence shows, are two important indicators in writing and publishing the ras. however, the interaction between these two crucial elements and the contribution of this interaction to the failure or success of the ras have not been given due attention to date. having this in mind and based on a sound theoretical framework, at...

An important goal of the Surface Water and Ocean Topography (SWOT) mission is to provide river width, height, slope estimate global discharges. To appraise feasibility SWOT data over India, present study utilizes simulator from Centre National D’Etudes Spatiales (CNES) generate a long time-series (three years) observations Mahanadi River basin in India. Two independent sources geometry are used...

Rivers play an essential role to humans and ecosystems, but they also burst their banks during floods, often causing extensive damage crop, property, loss of lives. This paper characterizes the 2014 flood Indus River in Pakistan using US Army Corps Engineers Hydrologic Engineering Centre Analysis System (HEC-RAS) model, integrated into a geographic information system (GIS) satellite images from...

1. introduction floods are among earth's most common and most destructive natural hazards. floods create geomorphic hazards via changes in sediment transport and channel configuration (e.g. channel width, lateral migration, planform changes, etc). in this context, floodplain zoning and its application in spatial planning is important in non- structural measures in order to reducing flood damage...

rivers are important water resources for human life, but sometimes cause irreparable damages. the flood plains are fertile terrains which are endangered by flood. flood hazard mapping is one of the basic methods in flood fighting. in order to decline flood damages, the simulation of the hydraulic behavior of the rivers during flood occurrence is very important. in this study, areas that are flo...

Rapid and reliable flood information is crucial for minimizing post-event catastrophes in the complex river basins of world. The Chenab River basin one world, facing adverse hydrometeorological conditions with unpredictable hydrologic response. Resultantly, many vicinities along undergo destructive inundation, resulting huge life economic losses. In this study, Hydrologic Engineering Centre–Hyd...
