Levee setback location and height are important issues in flood levee system design and modification. This paper derives an economic-engineering theory of the optimal trade-off of levee setback for height both for original and redesigned flood levees, demonstrating the interconnection of levee setback, height, costs and risks, and economically optimal design. These analyses assume stationary fl...

Record-breaking floods in September 2013 caused massive damage to homes and infrastructure across the Colorado Front Range and heavily impacted the Cache La Poudre River watershed. Given the unique nature of this watershed as a test-bed for tracking environmental pathways of antibiotic resistance gene (ARG) dissemination, we sought to determine the impact of extreme flooding on ARG reservoirs i...

Natural disasters such as floods and earthquakes impact many parts of Southeast Asia. In Malaysia, recent floods—such as those in 2014−2015—have caused untold damage to property and livelihoods. Up to that point, flood management had mainly emphasized disaster response, rather than risk-reduction strategies. The aim of this paper is to identify the local knowledge and practices of flood-affecte...

Karst environments are characterized by peculiar hydrologic features, and in particular by a very limited, if not absent, surface hydrography. Water tends to infiltrate rapidly underground through the complex network of fractures and karstic conduits in the rock mass. However, on the occasion of concentrated rainfall, as well as in case of prolonged precipitation, such network might not be able...

Space technology has made substantial contribution in all the three phases such as preparedness, prevention and relief phases of drought and flood disaster management. The Earth Observation satellites which include both geostationary and polar orbiting satellites provide comprehensive, synoptic and multi temporal coverage of large areas in real time and at frequent intervals and ‘thus’ have bec...

Thresholds based on critical combinations of amount/duration of precipitation and flood events were estimated for the Corgo hydrographic basin, in northern Portugal. Thirty-one flood events in the Corgo basin were identified between 1865 and 2011 from a database of hydrometeorological disasters in Portugal. The minimum, maximum, and pre-warning thresholds that define the boundaries for flood oc...

The aim of the study is to analyze and discuss possible climate change impacts on flood damages in Germany. The study was initiated and supported by the German insurance sector whereby the main goal was to identify general climate-related trends in flood hazard and damages and to explore sensitivity of results to climate scenario uncertainty. The study makes use of climate scenarios regionalize...

Floods are among the most frequent and costly natural disasters in terms of human hardship and economic loss. In recent years Europe suffered over 100 major damaging floods. Since 1998, floods have caused damages of some 700 facilities, the displacement of about half a million people and at least 25 billion Euro in insured economic losses. In the United States, about 90 percent of the damage ca...

This paper deals with the failure risk of masonry constructions under the effect of floods. It is developed within a probabilistic framework, with loads and resistances considered as random variables. Two complementary approaches have been investigated for this purpose: – a global approach based on combined effects of several governing parameters with individual weighted contribution (material ...

Flood Damage Assessment (FDA) is a key component in modern risk management frameworks providing an effective basis for decision making and the treatment of the risks. Current FDA methods do not consider the distinctiveness of buildings in analysis and therefore, cannot analyse them on a case-by-case basis, which is necessary for a variety of applications like engineering and design evaluation. ...
