The effectiveness of three simple flood operating rules in reducing the peak flow is compared for four simplified hydrograph shapes. The Minimize Flood Peak rule uses available flood storage capacity to store peak flows from an accurate hydrograph forecast. The less demanding Minimize Flooding Frequency operating rule releases water at or below channel capacity until the flood storage pool is f...
The impacts of flooding are expected to rise due to population increases, economic growth and climate change. Hence, understanding the physical and spatiotemporal characteristics of risk drivers (hazard, exposure and vulnerability) is required to develop effective flood mitigation measures. Here, the long-term trend in flood vulnerability was analysed globally, calculated from the ratio of the ...
Identifying the risk factors for morbidity and mortality effects pre-, during and post-flood may aid the appropriate targeting of flood-related adverse health prevention strategies. We conducted a systematic PubMed search to identify studies examining risk factors for health effects of precipitation-related floods, among Organisation for Economic Co-Operation and Development (OECD) member count...
Swarm intelligence refers to complex behaviors that arise from very simple individual behaviors and interactions, which is often observed in nature, especially among social insects such as ants. Although each individual (an ant) has little intelligence and simply follows basic rules using local information obtained from the environment, such as ant’s pheromone trail laying and following behavio...
due to increasing rate of flood risk throughout the world, including iran, it is necessary to identify and prioritize flood-contributing areas for flood control activities. in this study, a new approach on unit flood response method called “flood reduction method” was introduced which is applicable to prioritization of sub-basins for flood control activities. it was used to prioritize upstream ...
In this paper we present the data management tasks and tools used in a flood prediction application of the CROSSGRID project. The application consists of a computational core a cascade of three simulation stages, a workflow manager, two user interfaces and a data management suite. The project is based on the Grid technology, especially the Globus toolkit 2.4 and 3.2 and the EU DataGrid project....
A near real-time system is described, which provides spatial information of inland flood extent, using MOderate resolution Imaging Spectrometer (MODIS) optical reflectance and Advanced Microwave Scanning Radiometer (AMSR-E) microwave brightness temperature imagery, and flood volume through combination with a Digital Elevation Model (DEM). This information is an independent and useful addition t...
The aim of this paper is to analyse the differences in the long-term regimes of extreme precipitation and floods across the Alpine-Carpathian range using seasonality indices and atmospheric circulation patterns to understand the main flood-producing processes. This is supported by cluster analyses to identify areas of similar flood processes, both in terms of precipitation forcing and catchment...
Within the context of the Dutch Delta Programme, economically efficient flood protection standards for the entire Netherlands were calculated using a recently developed methodology for cost-benefit analysis and up-to-date insights into flood risk assessment. This results in economically efficient flood protection standards for different parts of the Netherlands that significantly differ from cu...
