Flash floods need to be monitored from a safe place, ideally with noncontact instruments installed at a riverbank and oriented so that they look obliquely at the water surface. The “inclined Lidar” technique could be useful for this purpose. It works based on the fact that a near-infrared Lidar mounted with a large incidence angle can detect suspended particles slightly below the surface, provi...

Abstract After a dry spring, in June 2020 several intense storms occurred at the headwaters of small basins Muráň and Zdychava rivers territory Muránska planina National Park (Slaná River basin, Slovakia). In first part study– according to hydrological survey made by authors after flash flood – peak discharge was reconstructed profiles. Next, waves were rainfall-runoff model NLC (non-linear cas...

A flood warning system incorporates telemetered rainfall and flow/water level data measured at various locations in the catchment area. Real-time accurate data collection is required for this use, and sensor networks improve the system capabilities. However, existing sensor nodes struggle to satisfy the hydrological requirements in terms of autonomy, sensor hardware compatibility, reliability a...

The analysis of historical disaster events is a critical step towards understanding current risk levels and changes in over time. Disaster databases are potentially useful tools for exploring trends, however, criteria inclusion associated descriptive characteristics not standardized. For example, some include only primary types, such as ‘flood’, while others subtypes, ‘coastal flood’ ‘flash flo...

This report provides a case study examining flood risks in the city of Vienna. The purpose is to illustrate an interdisciplinary approach to flood risk analysis, combining hydrological flood risk assessment and simulation modeling with the finances of flood risk management. Three scenarios were preliminarily identified for analysis: catastrophic flooding on a major European river (the Danube) t...

Due to the joint influence of climate and topography, flash flood disasters in Wende River Basin Jilin Province occurred repeatedly, causing serious casualties huge economic losses; July 2017, three floods with large rainfall intensity profound a row main stream River. Based on official measured data basin, typical processes (“July 13”, “July 20” “, “August 3 “) are selected discuss characteris...
