Some Comments on the Entropy-Based Criteria for Piping
(2015-04-15)
This paper is an extension of previous work which characterises soil behaviours using the grading entropy diagram. The present work looks at the piping process in granular soils, by considering some new data from ...
Integrating Entropy and Copula Theories for Hydrologic Modeling and Analysis
(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 ...
Simulating Crop Evapotranspiration Response under Different Planting Scenarios by Modified SWAT Model in an Irrigation District, Northwest China
(2015-10-06)
Modelling crop evapotranspiration (ET) response to different planting scenarios in an irrigation district plays a significant role in optimizing crop planting patterns, resolving agricultural water scarcity and facilitating ...
The Grading Entropy-based Criteria for Structural Stability of Granular Materials and Filters
(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 ...
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 ...
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 ...
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 ...
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 ...
