Nappe Flow Surges down a Rough-Stepped Sloping Channel
(2017-07-22)
Nappe flow applies to small discharges, and investigation of nappe flow surges helps to understand the mechanism of water flow in stepped open channels. The objective of this paper is to investigate the nappe flow surge ...
A copula-based precipitation forecasting model: Investigating the interdecadal modulation of ENSO’s impacts on monthly precipitation
(American Geophysical Union, 2014-01)
The influence of two large-scale circulation patterns (the El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO)), and the effect of the interdecadal modulation of ENSO on precipitation in the state ...
A bivariate mixed distribution with a heavy-tailed component and its application to single-site daily rainfall simulation
(American Geophysical Union, 2013-02)
This paper presents an improved bivariate mixed distribution, which is capable of modeling the dependence of daily rainfall from two distinct sources (e.g., rainfall from two stations, two consecutive days, or two instruments ...
Probability distribution functions for unit hydrographs with optimization using genetic algorithm
(2015)
A unit hydrograph (UH) of a watershed may be viewed as the unit pulse response function of a linear
system. In recent years, the use of probability distribution functions (pdfs) for determining a UH has received much ...
Spatial Disaggregation of Areal Rainfall Using Two Different Artificial Neural Networks Models
(2015-06-05)
The objective of this study is to develop artificial neural network (ANN) models, including multilayer perceptron (MLP) and Kohonen self-organizing feature map (KSOFM), for spatial disaggregation of areal rainfall in the ...
Future Climate Data from RCP 4.5 and Occurrence of Malaria in Korea
(2014)
Since its reappearance at the Military Demarcation Line in 1993, malaria has been occurring annually in Korea. Malaria is regarded as a third grade nationally notifiable disease susceptible to climate change. The objective ...
Entropy Spectral Analyses for Groundwater Forecasting
(2017-03-03)
Forecasting of monthly and annual groundwater levels is important for water resources management, irrigation, and assessment of climate change. This study employs entropy spectral analysis for forecasting monthly groundwater ...
Experimental Investigation of Influence of Vegetation on Flow Turbulence
(Scientific & Academic Publishing, 2015)
Vegetation in channels, rivers, reservoirs, and wetlands alters the flow turbulence characteristics. Vegetation has both positive and negative effects, depending on the objective of the hydraulic conduit. For example, it ...
Simulation of the entire range of daily precipitation using a hybrid probability distribution
(American Geophysical Union, 2012)
Underestimation of extreme values is a widely acknowledged issue in daily precipitation simulation. Nonparametric precipitation generators have inherent limitations in representing extremes. Parametric generators can ...
