Elaboración de cartografía de zonas inundables : aplicación al llano de inundación del río Arga (Navarra)

2000

La inundación es el riesgo natural de mayor impacto social y económico, la persistencia del problema a pesar de los continuos avances tecnológicos pone de manifiesto la necesidad de estudiar más detalladamente el comportamiento de las áreas inundables y elaborar una cartografía de riesgo que contribuya a un uso más racional del espacio. Este trabajo presenta el proceso de elaboración del mapa de riesgo del llano de inundación del río Arga (Navarra) en los municipios de Falces, Peralta y Funes. La demarcación de áreas inundables para diferentes valores de caudal máximo se llevó a cabo mediante la combinación de métodos estadísticos, hidrológicos, hidráulicos y geomorfológicos. Algunos proces…

Are Future School Teachers Qualified to Teach Flood Risk? An Approach from the Geography Discipline in the Context of Climate Change

2021

The aims of this research, based on a case study (trainee teachers of Primary degree and Secondary Education–MAES of the University of Valencia, Spain), are to analyse the students’ memories and perceptions of their training about floods

2019

Abstract. The cumulative occurrence of heavy precipitation and flood events during recent years in various Central European locations emphasises the urgent need to improve extreme rainfall observations and forecasts. Precipitation gauges based on a weighing system allow the recording of intense short-term precipitation events with a very high temporal resolution (down to 1 min). In this study, observational data that were collected during the period 2000 to 2016 for 126 stations of two corresponding measuring networks in the Central German state of Hesse were investigated for the first time to answer the following questions: (1) Are the recorded high-resolution precipitation data plausible …

Climate change impact on SWAT simulated streamflow in western Kenya

2008

Weather and climate extremes such as droughts and floods have far reaching impacts in Kenya. They have had implications in a variety of sectors including agriculture, water resources, health, energy, and disaster management among others. Lake Victoria and its catchment support millions of people and any impact on its ability to support the livelihoods of the communities in this region is of major concern. Thus, the main objective of this study was to assess the potential future climatic changes on the Nzoia catchment in the Lake Victoria basin, and how they might affect streamflow. The Soil and Water Assessment Tool was used to investigate the impact of climatic change on streamflow of the …

An Evaluation Matrix to Compare Computer Hydrological Models for Flood Predictions

2020

In order to predict and control the impacts of floods in torrents, it is important to verify the simulation accuracy of the most used hydrological models. The performance verification is particularly needed for applications in watersheds with peculiar climatic and geomorphological characteristics, such as the Mediterranean torrents. Moreover, in addition to the accuracy, other factors affect the choice of software by stakeholders (users, modellers, researchers, etc.). This study introduces a &ldquo

Effects of ecological flooding on the temporal and spatial dynamics of carabid beetles (Coleoptera, Carabidae) and springtails (Collembola) in a pold…

2011

Within the scope of the Integrated Rhine Program an ecological flood gate and channel was inserted into the polder “Ingelheim” to enhance animal and plant diversity. In 2008, carabid beetles and springtails were collected, using pitfall traps, to measure the effects of ecological flooding and a strong precipitation event at a flood-disturbed and a dry location in this area. At both localities, xerophilic and mesophilic carabid beetle species were dominant throughout the study period. The total number of individuals of hygrophilic species was comparatively constant, while species number increased, partly due to the changed moisture conditions caused by ecological flooding and str…

Managing Metro Manila

2017

Metro Manila residents are confronted everyday with the challenges of flooding, substandard housing and horrendous traffic. In this low altitude plain, any significant rainfall raises water levels in many small streams, and contributes to traffic jams. The rapid population growth of the metropolis has led to the proliferation of squatter areas, including alongside flood-prone rivers and railroad tracks. The lack of discipline and of decent garbage management contribute in turn to a worsening of floods when streams are covered with litter. The fast rise in motorization rates, coupled with the many imperfections of the public transport system, make Manila one of the most congested cities in t…

Towards a SDN-based architecture for analyzing network traffic in cloud computing infrastructures

2015

Currently, network traffic monitoring tools do not fit well in the monitoring of cloud computing infrastructures. These tools are not integrated with the control plane of the cloud computing stack. This lack of integration causes a deficiency in the handling of the re-usage of IP addresses along virtual machines, a lack of adaption and reaction on highly frequent topology changes, and a lack of accuracy in the metrics gathered for the networking traffic flowing along the cloud infrastructure. The main contribution of this paper is to provide a novel SDN-based architecture to carry out the monitoring of network traffic in cloud infrastructures. The architecture in based on the integration be…
