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...
For the construction of an irrigation district, geotechnical conditions existing soils in municipality Ponedera (Atlántico, Colombia) were analyzed, by means manual sampling and standard permeability test (SPT). This information was processed a database for analysis. The soil types obtained, most which classified as inorganic clays silts (CL ML), to lesser extent, silty clayey sands (SM SC), ma...
This paper describes an approach for the identification of flood-susceptible areas contributing to sustainability these in Giofiros river basin covering area 184 km2, located Southern Greece. is prone flooding with devastating consequences on people, environment, and economy. In this context, a geographic information system (GIS)–based multi-criteria decision analysis (MCDA) method potential fl...
A GIS multi-component module was developed within the ArcView GIS environment for processing and analysing weather radar precipitation data. The module is capable of: (a) reading geo-reference radar data and comparing it with rain-gauge network data, (b) estimating the kinematics of rainfall patterns, such as the storm speed and direction, and (c) accumulating radar-derived rainfall depths. By ...

اثرات مخرب اجتماعی و اقتصادی سیل در جوامع بشری واقعیتی انکارناپذیر است و همه ساله بسیاری از شهرهای جهان را با مشکل مواجه می سازد، لذا ایجاد سیستم های مدیریت سیلاب و ایمن سازی مناطق در معرض خطر امری لازم و ضروری است. در این راه یکی از اولین و اصلی ترین اقدامات، تعیین مناطق در معرض خطر و پهنه بندی پتانسیل خطر سیل می باشد که با توجه به شرایط سیلاب، بزرگی آن و هندسه رودخانه با روش های مختلفی تعیین ...
Development of rural areas in rivers margins and flood plains, without understanding and attention to the dynamical and hydrological conditions and upstream areas of the rivers will cause to increase flood risk and loss of life and financial. Flood zoning has many applications, in floodplain management. For management of the three major branches of the Halilrood River, Rabor, Roodar and Javaran...
