Multi-disasters took place in the Mampituba River basin, southern Brazil, as a consequence of passing two cyclones, July 2020. The first one was bomb cyclone that caused several storm winds, damaging rooftops and overthrow countless trees. second an extratropical brought extreme precipitation, triggered debris flow, flood, woody floods. In study area, there are National Parks (Aparados da Serra...

Two complementary GIS-based functions are designed and implemented to assess the expected degree of loss due to the occurrence of flood events. Each function processes institutional thematic layers and allows decision makers first to quantify the physical and the economic exposure of the elements at risk in a given study region and then to assess the expected degree of economic loss in relation...

• A database with flash floods and heavy rainfall events in Germany 2 URBAS project overview • Improving quality of flash flood forecasts URBAS is organised in an interdisciplanery manner. Aspects from city planning, hydrology, hydraulics, meteorology, damage assessment, emergency planning, and insurance issues are playing important roles. In order to get an overview over occurrence of urban fl...

There is growing concern that flooding is becoming more frequent and severe in Europe. A better understanding of flood regime changes and their drivers is therefore needed. The paper reviews the current knowledge on flood regime changes in European rivers that has traditionally been obtained through two alternative research approaches. The first approach is the data-based detection of changes i...

Distributed denial-of-service DDoS flood attacks remain great threats to the Internet. To ensure network usability and reliability, accurate detection of these attacks is critical. Based on Li’s work on DDoS flood attack detection, we propose a DDoS detection method by monitoring the Hurst variation of long-range dependant traffic. Specifically, we use an autoregressive system to estimate the H...

Multivariate patterns in commercial fisheries landings, effort and revenue from three adjacent estuarine and coastal systems were examined in eastern Australia between 9-month periods of flood (September 2000–May 2001) and drought (September 2002–May 2003). Patterns in species landings, methods of fishing effort and revenue per species were significantly different between flood and drought. Spe...

PURPOSE TrueBeams equipped with the 40 × 30 cm2 Electronic Portal Imaging Devices (EPIDs) are prone to image saturation at the image center when used with flattening filter free (FFF) photon energies. While cine imaging during treatment may not saturate because the beam is attenuated by the patient, the flood field calibration is affected when the standard calibration procedure is followed. Her...
