Future Climate Data from RCP 4.5 and Occurrence of Malaria in Korea
(2014-10-15)
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 ...
Evaluation of Bed Load in a Gravel-Bed River
(Scientific & Academic Publishing, 2015)
Bed load transport is needed for river training works, reservoir management, watershed management, and ecosystem maintenance. A number of equations have been developed for determining bed load transport, primarily for ...
Derivation of 2D Power-Law Velocity Distribution Using Entropy Theory
(2013)
The one-dimensional (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 SCS-CN Parameter S From Linearized Fokker-Planck Equation
(2003)
The potential maximum retention, S, of the Soil Conservation Service Curve Number (SCS-CN) method (SCS, 1956) was derived for a large set of published infiltration data ranging from Plainfield sand to Yololight clay using ...
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 ...
The Entropy Theory as a Tool for Modeling and Decision-making in Environmental and Water Resources
(2000-01)
Since the development of the entropy theory in the late 1940s and of the principle of maximum entropy (POME) in the late 1950s, there has been a proliferation of applications of the entropy theory in a wide spectrum of ...
A copula-based precipitation forecasting model: Investigating the interdecadal modulation of ENSO’s impacts on monthly precipitation
(2014-01-14)
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 ...
Numerical Solution of Fractional Advection-Dispersion Equation
(2004-05-01)
Numerical schemes and stability criteria are developed for solution of the one-dimensional fractional advection-dispersion equation (FRADE) derived by revising Fick’s first law. Employing 74 sets of dye test data measured ...
Predicting Longitudinal Dispersion Coefficient in Natural Streams by Artificial Neural Network
(2005-11-01)
An artificial neural network (ANN) model was developed to predict the longitudinal dispersion coefficient in natural streams and rivers. The hydraulic variables [flow discharge (Q), flow depth (H), flow velocity (U), shear ...
Sediment Graphs Based on Entropy Theory
(2014-08-20)
Using the entropy theory, this paper derives an instantaneous unit sediment graph (IUSG or USG) to determine sediment discharge and the relation between sediment yield and runoff volume. The derivation of IUSG requires an ...
