A Statistical Rainfall-Runoff Mixture Model with Heavy-Tailed Components
1 We present a conditional density model of river runoff given covariate information 2 which includes precipation at four surrounding stations. The proposed model is non3 parametric in the central part of the distribution and relies on Extreme-Value Theory 4 parametric assumptions for the upper tail of the distribution. From the trained con5 ditional density model, we can compute quantiles of v...
متن کاملSemidiurnal Tidal Currents Measured with Ocean Surface Radar around Isahaya Bay Mouth in Ariake Sound, Japan
Ariake Sound, in Kyushu Island of western part of Japan and connecting the small bay, Isahaya Bay, in the northwestern (Fig. 1) is strongly affected by large semidiurnal tide of which amplitude ranges from 3 to 5 m [3]. While Ariake Sound exhibits highly productive, red tides have occurred more frequently around the northern area of Isahaya Bay Mouth, causing damage to the sheries, recently [1]...
متن کاملAssessment of Heavy Metal Pollution in Chinese Suburban Farmland
A total of 650 arable soil samples were collected from the suburbs of Liaocheng, Shandong Province, China to identify the concentrations and the sources of heavy metals and to assess the environmental quality of soil. Subsequently, the contents of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in the samples were analyzed. The investigation revealed that the mean concentrations of As, Cd, Hg, Ni, Hg, and C...
متن کاملRainfall Runoff Modelling Based on Genetic Programming
The runoff formation process is believed to be highly non-linear, time varying, spatially distributed, and not easily described by simple models. Considerable time and effort has been directed to model this process, and many hydrologic models have been built specifically for this purpose. All of them, however, require significant amounts of data for their respective calibration and validation. ...
متن کاملThe contribution of heavy metal pollution derived from highway runoff to Guanabara Bay sediments--Rio de Janeiro/Brazil.
In this study, geochemical and particle size analyses of thirty-four street sediment samples collected from an urban environment around Guanabara Bay, shows highway run-off to be a potential source of heavy metals for the pollution of near-shore sedimentary deposits. Concentrations of Fe, Mn, Zn, Cu, Pb, Cr and Ni were found to be higher in these sediments when compared to concentrations found ...
