The operation of flood retarding areas does not attract much attention, although they are important components of flood control systems. Poor operation of such areas restricts not only the socio-economic development of the flood retarding area, but also limits scientific flood control options. As the second-largest flood retarding area in China, with more than 2000 km2 and 300 polders, the Hong...

Introduction Baumgardner (1986, 1990, 1994a, 1994b) has advanced the proposition that the essential process responsible for the large-scale tectonic changes contemporaneous with the Genesis Flood was runaway subduction of the pre-Flood oceanic lithosphere. Precursory to the runaway would be some pattern of stress concentration and shear zone formation in the pre-Flood lithosphere, concentrated ...

introduction flood is an inevitable natural phenomenon occurring from time to time in all rivers and natural drainage systems, which not only damages the lives, natural resources and environment, but also causes the loss of economy and health. so estimation and prediction flood hazard is very important spatially in the watersheds without measurement station. there are many models in the water a...

Risky land use decisions have led to large amounts of damages from flooding. Wildfires can potentially alter the risk of flooding by increasing the likeliness of high flow events due to multiple physical processes that increase the volume and intensity of runoff and erosion. In June and July of 2008, the Basin Complex fire burned 240,170 acres of the Arroyo Seco Watershed located in Monterey Co...

Accurate, precise and timely forecasts of flood wave arrival time, depth and velocity at each point of the floodplain are essential to reduce damage and save lives. Current computational capabilities support hydraulic models of increasing complexity over extended catchments. Yet a number of sources of uncertainty (e.g., input and boundary conditions, implementation data) may hinder the delivery...

Early flood warning and real-time monitoring systems play a key role in flood risk reduction and disaster response decisions. Global-scale flood forecasting and satellite-based flood detection systems are currently operating, however their reliability for decision making applications needs to be assessed. In this study, we performed comparative evaluations of several operational global flood fo...

In contrast to recent advances in projecting sea levels, estimations about the economic impact of sea level rise are vague. Nonetheless, they are of great importance for policy making with regard to adaptation and greenhouse-gas mitigation. Since the damage is mainly caused by extreme events, we propose a stochastic framework to estimate the monetary losses from coastal floods in a confined reg...
