Riesgo por inundación asociada a eventos de precipitación extraordinaria en la subcuenca del río La Antigua, Veracruz. Colegio de Postgraduados
Larios Tlali, Hugo.
El objetivo del presente estudio fue aplicar el modelo de simulación hidráulica HEC-RAS para delimitar las zonas con riesgo a inundación en la subcuenca del río La Antigua, Ver., utilizando la metodología del Centro Nacional de Prevención de Desastres (CENAPRED) que considera la vulnerabilidad y el peligro de un sistema ante la ocurrencia de un fenómeno extremo perturbador. El modelo HEC-RAS usa ecuaciones diferenciales determinísticas que simulan el comportamiento y la dinámica de los niveles de agua en secciones transversales del cauce; su aplicación bajo condiciones de flujo no permanente y régimen mixto, permitió definir las áreas de inundación alcanzadas durante una avenida extraordinaria. Para la simulación hidráulica se construyeron hidrogramas...

Dealing with change and uncertainty within the regulatory frameworks for flood defense infrastructure in selected European countries Ecology and Society
van Doorn-Hoekveld, Willemijn J; Utrecht Centre for Water, Oceans and Sustainability Law, Utrecht University School of Law, The Netherlands; w.j.hoekveld@uu.nl; Priest, Sally; Flood Hazard Research Centre, Middlesex University, UK; s.priest@mdx.ac.uk.
Whereas existing literature on the interactions among law, adaptive governance, and resilience in the water sector often focuses on quality or supply issues, this paper addresses adaptation in national water laws in relation to increasing flood risks. In particular, this paper analyzes the extent to which legal rules governing flood defense infrastructure in a selection of European countries (England, France, Sweden, and The Netherlands) allow for response and adaptation to change and uncertainty. Although there is evidence that the legal rules on the development of new infrastructure require that changing conditions be considered, the adaptation of existing infrastructure is a more complicated matter. Liability rules fail to adequately address damages...

Dealing with Uncertainty in Flood Management Through Diversification Ecology and Society
Aerts, Jeroen C. J. H.; ; jeroen.aerts@ivm.falw.vu.nl; Botzen, Wouter; ; Wouter.Botzen@ivm.falw.vu.nl; Veen, Anne van der; ; a.vanderveen@ctw.utwente.nl; Krywkow, Joerg; ; j.krywkow@ctw.utwente.nl; Werners, Saskia; ; Saskia.Werners@wur.nl.
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 risks thereby reducing the overall risk of the total portfolio of investments. This paper shows that through systematically combining four different flood protection measures in portfolios containing three or four measures; risk is reduced compared with portfolios that only contain one or two measures. Adding partly uncorrelated measures to the portfolio diversifies...
