In this paper, the problem of flooding management using hybrid model predictive control is presented and applied to the Ebro River in Spain. The Ebro river presents flooding episodes in the city of Zaragoza during spring when snow melts in the Pyrenees. To avoid flooding in living areas, some lands outside the city are prepared to be flooded. This paper presents a control approach to determine ...

In this paper, we present the Flash flooding protocol that exploits the capture effect to produce low-latency network floods. The capture effect is the ability of some radios to correctly receive one of several concurrently transmitted messages, even if the received strengths of the two messages are almost the same. We exploit this phenomenon in a network flooding scenario by allowing nodes to ...

Information dissemination (flooding) forms an integral part of routing protocols, network management, service discovery and information collection. Given the broadcast nature of ad hoc network communications, information dissemination provides a challenging problem. In this paper we compare the performance of existing distributed ad hoc network flooding algorithms indentifying stengths and weak...

Countermeasures to urban flooding should consider long-term perspectives, because climate change impacts are unpredictable and complex. Urban green spaces have emerged as a potential option to reduce urban flood risks, and their effectiveness has been highlighted in notable urban water management studies. In this study, flooded areas in Seoul, Korea, were divided into four flooded area types by...

In this paper, the problem of flooding management at the Ebro River in Spain is presented. The Ebro river presents flooding episodes in the city of Zaragoza in spring when snow melts in the Pyrenees. To avoid flooding in living areas, some lands outside the city are prepared to be flooded. This paper presents a hybrid model predictive control approach to determine and fix the level of flooding ...

Flooding frequency is predicted to increase during the next decades, calling for a better understanding of impacts on terrestrial ecosystems and for developing strategies to mitigate potential damage. Plant diversity is expected to buffer flooding effects by providing a broad range of species' responses. Here we report on the response of soil processes to a severe summer flood in 2013, which af...

This study contributes to the understanding of behavioural responses to climate change induced extreme weather events. It suggest a microeconometric method for measuring flooding related risk preferences of affected individuals. The method is outlined using the empirical case of agricultural production in floodplains of the UK over 28 years. A quasi-experimental approach to measure differences ...
