A rainfall regionalization method based on variation coefficient was applied with a variant in the construction of flash flood hyetographs several return periods using shape historical event that occurred September 2021 Tlalnepantla River basin, Mexico, caused severe damage to population and its infrastructure few hours. The simulated semi-distributed model free software HEC-HMS order obtain ou...

The NW Mediterranean region experiences every year heavy rainfall and flash floods that occasionally produce catastrophic damages. Less frequent are floods that affect large regions. Although a large number of databases devoted exclusively to floods or considering all kind of natural hazards do exist, usually they only record catastrophic flood events. This paper deals with the new flood databa...

This paper describes the impacts of unplanned urban expansion and land surface change in the city of Bamenda in Cameroon, the underlying causes and the ecological and social implications. This expansion has placed great stress on forest, land and water ecosystems. Much of the city’s rapid growth in population has been accommodated in informal settlements on steep slopes and flood plains, with l...

Emergency situations are unavoidable. This paper presents the functions inherent in a prototype system that was developed in Malaysia for emergency management. The prototype is potentially useful in Selangor, a state in Malaysia that is prone to natural disasters such as flash floods and landslides. The paper is presented as a report of our on-going project in Malaysia and the intended future w...

Rainfall events in the United Kingdom during the twentieth century have been surveyed and those identified as extreme by the Flood Studies Report (1975) standards have been examined for common features. Events of duration up to 60 hours were considered in order to investigate those that could cause flash floods. More than half of the 50 events identified were short-period convective storms. The...

This paper presents the results of geohazards mapping and evaluation their role in modifying urban landscape Poznań, Poland. Information on specific to an lowland area (river floods, flash mass movement, wind erosion) because increasing climate change was compiled into a geomorphological map. The most spatially widespread Poznań include: (a) moraine hills/uplands: erosion, floods (4.9% city are...

Flash floods are a type of catastrophic disasters which cause significant losses life and property worldwide. In recent years, machine learning techniques have become powerful tools for evaluating flash flood susceptibility. This research applies stacking blending ensemble approaches to assess the potential in Jiangxi, China. Four base models – linear regression, K-nearest neighbours, support v...
