Integrating statistical information concerning historical floods: ranking and interval return period estimation

Fernández, Elena; Colubi, Ana; González-Rodríguez, Gil; … - In: Natural Hazards 62 (2012) 2, pp. 459-483

The importance of the historical information in flood analysis has previously been underlined. In this context, we present an integral methodology aimed at the establishment of return periods of different flood units on the unique basis of historical data. Specifically, the reconstruction of the...

Hydrological modeling of typhoon-induced extreme storm runoffs from Shihmen watershed to reservoir, Taiwan

Chang, Chiwen; Huang, Wenrui - In: Natural Hazards 67 (2013) 2, pp. 747-761

Typhoon-induced extreme storm runoffs often cause flood hazards. In this study, a hydrological model (HEC-HMS) was applied to Shihmen watershed located in Taiwan. Three typhoon-induced storm events, with return period ranging from 1 to 90 years, were used in case studies to characterize storm...

Numerical modeling of the Rideau Valley Watershed

Ahmed, Ferdous - In: Natural Hazards 55 (2010) 1, pp. 63-84

Using the Mike11 modeling system by the Danish Hydraulic Institute, a detailed model of the Rideau Valley Watershed was constructed. It includes 532 km of rivers and lakes, 106 basins, 122 bridges and culverts, and 20 water control structures. The model was calibrated using measured streamflow...

Effects of land use change on flood characteristics in mountainous area of Daqinghe watershed, China

Li, Jianzhu; Feng, Ping; Chen, Fulong - In: Natural Hazards 70 (2014) 1, pp. 593-607

Land use has changed in the Daqinghe watershed during 1956–2005, and it has influenced the flood peak and volume. In order to reveal the effects of land use change on flood characteristics in Daqinghe watershed, we selected 2 sub-watersheds and used remote-sensed land use data of 1980 and 1996...

A dual effect of urban expansion on flood risk in the Pearl River Delta (China) revealed by land-use scenarios and direct runoff simulation

Du, Shiqiang; Rompaey, Anton Van; Shi, Peijun; … - In: Natural Hazards 77 (2015) 1, pp. 111-128

Since the late 1970s, the Pearl River Delta (PRD) in China has undergone a rapid transition from an agricultural landscape to a metropolitan area. The rapid urbanization has not only increased the area of impervious surfaces in the central plain; it has displaced farmland to the hilly peripheral...

Statistical analysis on extreme wave height

Teena, N.; Kumar, V. Sanil; Sudheesh, K.; Sajeev, R. - In: Natural Hazards 64 (2012) 1, pp. 223-236

The classical extreme value theory based on generalized extreme value (GEV) distribution and generalized Pareto distribution (GPD) is applied to the wave height estimate based on wave hindcast data covering a period of 31 years for a location in the eastern Arabian Sea. Practical concern such...

Estimation of Tsunami Risk for the Coasts of Peru and Northern Chile

KULIKOV, EVGUENI; RABINOVICH, ALEXANDER; THOMSON, RICHARD - In: Natural Hazards 35 (2005) 2, pp. 185-209

Data for tsunamigenic earthquakes and observed tsunami run-up are used to estimate tsunami-risk for the coasts of Peru and northern Chile for zones bounded by 5–35° S latitude. Tsunamigenic earthquake estimates yield magnitudes of 8.52, 8.64, and 8.73 for recurrence periods of 50, 100, and...

Probabilistic seismic hazard assessment for Lake Van basin, Turkey

Selcuk, Levent; Selcuk, Azad; Beyaz, Turgay - In: Natural Hazards 54 (2010) 3, pp. 949-965

The seismic hazard for the Lake Van basin is computed using a probabilistic approach, along with the earthquake data from 1907 to present. The spatial distribution of seismic events between the longitudes of 41–45° and the latitudes of 37.5–40°, which encompasses the region, indicates...

A probabilistic approach toward earthquake hazard assessment using two first-order Markov models in Northeastern India

Mohanty, William; Mohapatra, Alok; Verma, Akhilesh - In: Natural Hazards 75 (2015) 3, pp. 2399-2419

In this paper, a probabilistic analysis of earthquakes of a seismically active region [Northeast (NE) India] is carried out in the temporal domain. Two models have been used; the first one is for the probability estimation of at least one major earthquake striking the area under consideration...
