Flood risk mapping aims to create an easily read and rapidly accessible map prioritize the mitigation effects. This study presents empirical approach flood through integration of Analytical Hierarchy Process (AHP) Geographic Information System (GIS) techniques. SRTM 30m DEM is processed using ArcGIS 10.3 software. The methodology includes selection area, identification factors responsible for c...

INTRODUCTION In the UK national planning guidance on Development and Flood Risk is now given in Planning Policy Guidance Note 25 (DTLR, July 2001), which replaces Circular 30/92 (DOE, 1992). Amongst other things the guidance in PPG25 states “Policies in redevelopment plans should outline the consideration which will be given to flood issues, recognising the uncertainties that are inherent in th...

This paper shows, through a numerical example, how to develop portfolios of flood management activities that generate the highest return under an acceptable risk for an area in the central part of the Netherlands. The paper shows a method based on Modern Portfolio Theory (MPT) that contributes to developing flood management strategies. MPT aims at finding sets of investments that diversify risk...

Various regions in Europe have suffered from severe flooding over the last decennium. Earth observation techniques can contribute toward more accurate flood hazard modelling and they can be used to assess damage to residential properties, infrastructure and agricultural crops. For this study, detailed land cover maps were created by using IKONOS-2 high spatial resolution satellite imagery. The ...

The Dutch government is in the process of revising its national flood safety policy. The current Dutch Flood Defense Act lays down design standards for the Dutch flood defenses. These standards have been based on/rationalized by economic optimizations in which investment costs are balanced against the discounted value of (potential) future losses. Loss of life is not considered separately. This...

The Flood Risk in the Netherlands project (Dutch acronym: VNK2) is a large-scale probabilistic risk assessment for all major levee systems in the Netherlands. This article provides an overview of the methods and techniques used in the VNK2 project. It also discusses two examples that illustrate the potential of quantitative flood risk assessments such as VNK2 to improve flood risk management pr...

Flood management is an important approach to reduce damage caused by floods. In this context, technological architectures which work in real-time are needed. However, Brazil has faced many structural difficulties in obtaining updated information on the current state of its rivers. To address this problem, this paper outlines a geosensor dashboard called AGORA-GeoDash, which processes data strea...

Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...

Abstract: This paper presents the methodology and procedure for flood risk assessment using GIS and flood inundation model (FIM) based on the “micro-zonation concept” in which an entire floodplain considered is divided into numerous unit areas (meshes or grids). In this study, Shinkawa-river floodplain around Nagoya City of Aichi Prefecture in Japan an urbanized lowland area, which was greatly ...
