extended abstractintroduction the recognition of behaviors of the atmospheric circulation patterns and effective climatic elements in occurrence of flood is very important, especially because abnormal climate changes such as global warming in recent years tend to change in atmospheric circulation patterns and outbreak climatic inelegances in many areas in the world. intensive and torrential pre...

This study aims at providing expertise for preparing public-based flood mapping and estimating flood risks in growing urban areas. To model and predict the magnitude of flood risk areas, an integrated Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) analysis techniques are used for the case of Eldoret Municipality in Kenya. The flood risk vulnerability mapping follows ...

Appropriate precautions in the case of flood occurrence often require long lead times (several days) in hydrological forecasting. This in turn implies large uncertainties that are mainly inherited from the meteorological precipitation forecast. Here we present a case study of the extreme flood event of August 2005 in the Swiss part of the Rhine catchment (total area 34 550 km2). This event caus...

The analog technique is applied to the analysis of flood runoff. A quasi-linear analog model has been developed for simulating the runoff-producing characteristics of a drainage system. Where storage is linear a unique relationship correlating the inflow and outflow peaks is derived. A technique for synthesizing flood-frequency distribution is also proposed, whereby the effects of a linearor a ...

Poyang Lake and Dongting Lake are the two largest freshwater lakes in China. The lakes are located approximately 300 km apart on the middle reaches of the Yangtze River and are differently connected through their respective tributary systems, which will lead to different river–lake water exchanges and discharges. Thus, differences in their morphological and hydrological conditions should induce...

This paper demonstrates the design process, implementation and experimental verification of a Flood Level Monitoring system. The main objective of the proposed system is to be able to read the water level at every second, display it to the supervisor and alert the affected populace and relevant authorities by means of an alarm and short message system (SMS) when the level of water surpasses a u...

Denial-of-Service (DoS) flooding attacks have become a serious threat to the reliability of the Internet. Web servers face all kinds of users; some of them engage malicious activities to degrade or completely block network services, such as flooding attacks. As a result, lots of resource and bandwidth on web sites might be wasted. While many approaches exist to filter network-level attacks, the...

Flooding is a serious and increasing problem. As a result, there is a need to deploy more sophisticated sensor networks to detect and react to flooding. This paper outlines a demonstration which showcases a deployed flood monitoring platform, which uses WSN technologies and next generation middleware to improve support for flood warning.

In this paper we describe a visualization system for an emergency simulation. We start by presenting a flooding emergency case scenario and all the elements that are involved in it. Then we describe the design decisions that were made in order to create a credible representation of the scene. This includes using a game engine to render the scenario using a three-dimensional terrain, with object...
