RISEmerging Fields in Hydrology
Publisher: American Society of Civil Engineers
Abstract: Forum papers are thought-provoking opinion pieces or essays founded in fact, sometimes
containing speculation, on a civil engineering topic of general interest and relevance
to the readership of the journal. The views ...
Multivariate Modeling of Annual Instantaneous Maximum Flows Using Copulas
Publisher: American Society of Civil Engineers
Abstract: Although copula functions have been successively applied to flood frequency analysis, their application has usually been restricted to modeling bivariate dependence. This is because higher-dimensional expressions are only ...
Simulating Hydrological Drought Properties at Different Spatial Units in the United States Based on Wavelet–Bayesian Regression Approach
Publisher: American Meteorological Society
Abstract: ecause of their stochastic nature, droughts vary in space and time, and therefore quantifying droughts at different time units is important for water resources planning. The authors investigated the relationship between ...
Design Water Amount for Reservoir Management and Operation
Publisher: American Society of Civil Engineers
Abstract: Reservoirs for flood protection are normally designed by using the annual maximum design flood (AMDF). However, management and operation of a reservoir require regulation of intrayear runoff instead of interyear runoff. ...
Flow Field around Semielliptical Abutments
Publisher: American Society of Civil Engineers
Abstract: Hydraulic structures in rivers employ abutments of different shapes. An abutment causes a scour hole around the bottom of the structure in the river. The scour hole grows no further when the turbulence fluctuations and bed ...
Suspended Sediment Concentration and Discharge in Open Channels Using Rényi Entropy
Publisher: American Society of Civil Engineers
Abstract: The vertical distribution of suspended sediment concentration in an open channel is modeled using Rényi entropy. The model, derived by invoking the principle of maximum entropy, is tested against field and laboratory ...
Prediction of Local Scour Depth Downstream of Sluice Gates Using Harmony Search Algorithm and Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: Using two coupled models, this study predicts the maximum local scour depth downstream of sluice gates. The models are an artificial neural network (ANN) coupled with the harmony search (HS) algorithm, and an ANN coupled ...
Derivation of Velocity, Eddy Viscosity, and Mixing Length Models in Pipe and Symmetric Channel Flow Using Incomplete Information–Based Entropy
Publisher: American Society of Civil Engineers
Abstract: AbstractA single hypothesis of the cumulative distribution function was proposed to derive
the incomplete information–based entropy model for the mean velocity distribution
in full pipe flow (fully filled with fluid) and ...
Improved Method for Sustainable Soil and Water Quality Prediction Using a CNN-LSTM Hybrid Model and Particle Swarm Optimization
Publisher: American Society of Civil Engineers
Abstract: AbstractFundamental to sustainable development is the management of soil and water resources,
particularly in the most vulnerable regions, such as deltas. This calls for the development
of models that can handle complex ...
One-Dimensional Linear Kinematic Wave Solution for Overland Flow under Moving Storms Using the Method of Characteristics
Publisher: American Society of Civil Engineers
Abstract: The kinematic wave theory has been a widely accepted technique for modeling overland flow. Although it is recognized that overland flow is nonlinear, linear approximations have nonetheless been applied and found to be ...
