Assessing the impact of endmember selection on the accuracy of satellitebased spatial variability models for actual evapotranspiration estimation
(American Geophysical Union, 2013) 
A bivariate mixed distribution with a heavytailed component and its application to singlesite daily rainfall simulation
(American Geophysical Union, 201302)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 ... 
A copulabased precipitation forecasting model: Investigating the interdecadal modulation of ENSO’s impacts on monthly precipitation
(20140114)The influence of two largescale 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 ... 
Derivation of 2D PowerLaw Velocity Distribution Using Entropy Theory
(2013)The onedimensional (1D) power law velocity distribution, commonly used for computing velocities in open channel flow, has been derived empirically. However, a multitude of problems, such as scour around bridge piers, ... 
Derivation Of The SCSCN Parameter S From Linearized FokkerPlanck Equation
(2003)The potential maximum retention, S, of the Soil Conservation Service Curve Number (SCSCN) method (SCS, 1956) was derived for a large set of published infiltration data ranging from Plainfield sand to Yololight clay using ... 
Effect of Groundwater Pumping on Seawater Intrusion in Coastal Aquifers
(Sultan Qaboos University, 2002)Many aquifers around the globe are located in coastal areas and are thus subjected to the seawater intrusion phenomenon. The growth of population in coastal areas and the conjugate increase in human, agricultural, and ... 
Entropy theory for derivation of infiltration equations
(American Geophysical Union, 2010)An entropy theory is formulated for modeling the potential rate of infiltration in unsaturated soils. The theory is composed of six parts: (1) Shannon entropy, (2) principle of maximum entropy (POME), (3) specification ... 
Entropy theory for movement of moisture in soils
(American Geophysical Union, 2010)An entropy theory is formulated for one‐dimensional movement of moisture in unsaturated soils in the vertically downward direction. The theory is composed of five parts: (1) Tsallis entropy, (2) principle of maximum entropy, ... 
Entropy theorybased criterion for hydrometric network evaluation and design: Maximum information minimum redundancy
(American Geophysical Union, 2012)Hydrometric information constitutes the fundamental input for planning, design, operation, and management of water resources systems. How to optimally site monitoring gauges such that they are effective and efficient in ... 
Entropycopula method for singlesite monthly streamflow simulation
(American Geophysical Union, 2012)An entropycopula method is proposed for singlesite monthly streamflow simulation. In this method, the joint distribution of adjacent monthly streamflows is constructed using the copula method, whereas the marginal ... 
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 ... 
Model Error In Flood Frequency Estimation
(2002)Asymptotic bias in large quantiles and moments for three parameter estimation methods, including the maximum likelihood method (MLM), moments method (MOM) and linear moments method (LMM), is derived when a probability ... 
Modeling multisite streamflow dependence with maximum entropy copula
(American Geophysical Union, 2013)Synthetic streamflows at different sites in a river basin are needed for planning, operation, and management of water resources projects. Modeling the temporal and spatial dependence structure of monthly streamflow at ... 
Monthly river flow simulation with a joint conditional density estimation network
(American Geophysical Union, 2013)River flow synthesizing and downscaling are required for the analysis of risks associated with water resources management plans and for regional impact studies of climate change. This paper presents a probabilistic model ... 
A multimodel regressionsampling algorithm for generating rich monthly streamflow scenarios
(American Geophysical Union, 2014)This paper presents a multimodel regressionsampling algorithm (MRS) for monthly streamflow simulation. MRS is motivated from the acknowledgment that typical nonparametric models tend to simulate sequences exhibiting too ... 
A new frequency domain analytical solution of a cascade of diffusive channels for flood routing
(AGU Publications, 2015)Simplified flood propagation models are often employed in practical applications for hydraulic and hydrologic analyses. In this paper, we present a new numerical method for the solution of the Linear Parabolic Approximation ... 
On the informative value of the largest sample element of logGumbel distribution
(Versita, 200712)Extremes of stream flow and precipitation are commonly modeled by heavytailed distributions. While scrutinizing annual flow maxima or the peaks over threshold, the largest sample elements are quite often suspected to be ... 
Patterns of grainsize temporal variation of sediment transported by overland flow associated with moving storms: interpreting soil flume experiments
(Copernicus Publications on behalf of the European Geosciences Union, 2011)This study describes and interprets the evolution of grainsize distribution of sediment yields generated in an experimental soil flume subjected to downstream and upstream moving rain storms. Results of laboratory ... 
Physics Of Flood Frequency Analysis. Part I. Linear Convective Diffusion Wave Model
(2002)It is hypothesized that the impulse response of a linearized convective diffusion wave (CD) model is a probability distribution suitable for flood frequency analysis. This flood frequency model has two parameters, which ... 
Probability distribution functions for unit hydrographs with optimization using genetic algorithm
