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 ...
-
(American Geophysical Union, 2012-06-13)An entropy-copula method is proposed for single-site monthly streamflow simulation. In this method, the joint distribution of adjacent monthly streamflows is constructed using the copula method, whereas the marginal ...
-
(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 ...
-
(The British Society for Research in Agricultural Engineering, 1982)Recession characteristics play an important role in the design of border irrigation systems. This is particularly true of those borders which have closed downstream ends where surface storage is large even after the cessation ...
-
(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 ...
-
(Academic Journals Inc., 2008)This study evaluates the feasibility of using artificial neural networks (ANNs) methodology for estimating the groundwork level in some piezometers implanted in complex aquifer of Northwestern Iran. This aquifer is the ...
-
(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 ...
-
(2015-05-04)This paper deals with three grading entropy-based rules that describe different soil structure stability phenomena: an internal stability rule, a filtering rule and a segregation rule. These rules are elaborated on the ...

Granulometric characterization of sediments transported by surface runoff generated by moving storms (Copernicus, 2008-12-16)Due to the combined effect of wind and rain, the importance of storm movement to surface flow has long been recognized, at scales ranging from headwater scales to large basins. This study presents the results of laboratory ...
-
(2014-08-06)Three Archimedean copulas were employed to model annual maximum flood peak data of different lengths. Estimation methods based on ranks were employed for parameter estimation. Marginals were modeled with the generalized ...
-
(1995-02)Five major modifications to the Galerkin finite-element formulation for solute transport were made in this study: (1) A mixed formulation for the time-derivative term of the governing equation was developed by combining ...
-
(2015-04-15)Entropy is a measure of uncertainty and has been commonly used for various applications, including probability inferences in hydrology. Copula has been widely used for constructing joint distributions to model the dependence ...
-
(American Society of Agricultural and Biological Engineers, 2011)The instantaneous unit hydrograph (IUH) is a commonly used method for computing surface runoff hydrographs from small watersheds. Assuming travel time as a random variable, a general equation for IUH is derived using the ...
-
(American Meterological Society, 2012-02)Drought forecasting is important for drought risk management. Considering the El Niño–Southern Oscillation (ENSO) variability and persistence in drought characteristics, this study developed a wavelet and fuzzy logic (WFL) ...
-
(2002-10-01)Using a new channel shape equation for straight channels and a more versatile channel shape or local flow depth equation for natural streams a method is developed for prediction of the longitudinal dispersion coefficient ...
-
(2001-11)An analytical method is developed to determine the longitudinal dispersion coefficient in Fischer’s triple integral expression for natural rivers. The method is based on the hydraulic geometry relationship for stable rivers ...
-
(2015-01)Decision making for water resources is needed for land-use change due to urbanisation, which impacts hydrological variables such as mean annual runoff (MAR) of catchments. Urbanisation introduces some degree of uncertainty ...
-
(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 ...
-
(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 ...
-
(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 ...
