Intense events of rainfalls in Piemonte
precipitation intense events inorganic particulate matter
2015/9/16
The possibility of studying the precipitations recorded in a large number of meteorological stations in Piemonte
led us to analyse what has happened in the last century. A comparison between periods ...
Characteristics of extreme heavy precipitation events occurring in the area of Cracow (Poland)
autocorrelation Hershfield’s statistical method probability distribution probable maximum precipitation spectral analysis
2015/3/10
The variability of extremely heavy precipitation events with duration of 120 min occurring in the area of Cracow, southern Poland was assessed. The analysis was performed using time series of maximum ...
Analyzing Spatiotemporal Patterns of Extreme Precipitation Events in Southeastern Anatolia
TRMM, Extreme events GEV Shape parameter Precipitation South-eastern Anatolia
2014/4/22
Extreme environmental events, such as floods, droughts, rainstorms, and strong winds have severe consequences for human society. Changes in extreme weather and climate events have significant impacts ...
Characterization of peak flow events with local singularity method
peak flow events local singularity method
2009/10/30
Three methods, return period, power-law frequency plot (concentration-area) and local singularity index, are introduced in the paper for characterizing peak flow events from river flow data for the pa...
A relation between return periods of hydrological events in annual maxima and
partial duration series respectively is shown to be exactly fulfilled when the events
take place according to a Poisson ...
All raingauge measurements give only one-point values. Since the practical
applications of rain data always deal with areal measures, the knowledge of
areal distribution of rain is very important fo...
Assessment of True Variability of Small Rainfall Events in a Small Mountainous Watershed in the Summer
Assessment True Variability Small Rainfall Events Mountainous Watershed
2009/10/28
The standard error of mean areal rainfall was calculated for various densities
of rain gauge network in a small mountainous watershed in the summer of
1978. It is shown that a) the optimum gauge den...
Areal Intensity-Duration-Frequency Curves for Short Term Rainfall Events in Lund
Areal Intensity-Duration-Frequency Curves Short Term Rainfall Events
2009/10/28
Design Storms, which are usually derived from point intensity-durationfrequency
(i-d-f) relationships, neither reflect the areal variations of the rainfall
pattern nor the dynamics of the moving sto...
The speed and direction of movement of rainfall patterns, assumed constant
during any given storm, can be derived from data sets comprised of the coordinates
(x, y) of a number of rainfall recording...
The Correlation Between Extreme Wind and Flood Events in Unregulated River Basins
Correlation Extreme Wind Flood Events Unregulated River Basins
2009/10/22
The aim of this investigation is to improve the method for calculating design
wind speed used for wave run up at water reservoirs. It is focused on the relation
between extreme flood and wind events...
Bank erosion events and processes in the Upper Severn basin
Photo-Electronic Erosion Pin Bank erosion Upper Severn basin
2009/6/8
This paper examines river bank retreat rates, individual erosion events, and the processes that drive them in the Upper Severn basin, mid-Wales, UK. Traditional erosion pin networks were used to deliv...
Evaluation of a conceptual rainfall forecasting model from observed and simulated rain events
rainfall forecasting simulated rain events
2009/6/5
Very short-term rainfall forecasting models designed for runoff analysis of catchments, particularly those subject to flash-floods, typically include one or more variables deduced from weather radars...
Threshold effects in catchment storm response and the occurrence and magnitude of flood events：implications for flood frequency
catchment storage flood frequency flood
2009/5/12
The aim of this paper is to illustrate the effects of selected catchment storage thresholds upon runoff behaviour, and specifically their impact upon flood frequency. The analysis is carried out with ...
Discharges of past flood events based on historical river profiles
flood events historical river profiles
2009/5/6
This paper presents a case study on the estimation of peak discharges of extreme flood events during the 19th century of the Neckar River located in south-western Germany. It was carried out as part o...
Comparison of different multi-objective calibration criteria using a conceptual rainfall-runoff model of flood events
rainfall-runoff flood event
2009/4/28
A conceptual lumped rainfall-runoff flood event model was developed and applied on the Gardon catchment located in Southern France and various single-objective and multi-objective functions were used ...
