Closure to “<i>Fourier Analysis of Dissipative FEM Channel Flow Model</i>” by Nikolaos D. Katopodes (July, 1984, Vol. 110, No. 7)
Publisher: American Society of Civil Engineers
Closure to “<i>A Dissipative Galerkin Scheme for Open‐Channel Flow</i>” by Nikolaos D. Katapodes (April, 1984)
Publisher: American Society of Civil Engineers
A Dissipative Galerkin Scheme for Open‐Channel Flow
Publisher: American Society of Civil Engineers
Abstract: The finite element method based on the classical Galerkin formulation produces very poor results when applied to discontinuous channel flow. A variance of the Galerkin method is proposed that exhibits highly selective ...
Fourier Analysis of Dissipative fem Channel Flow Model
Publisher: American Society of Civil Engineers
Abstract: The algorithmic properties of a dissipative Galerkin scheme for openchannel flow are investigated by means of a Fourier analysis based on the linearized equations describing kinematic and dynamic wave motion in shallow ...
Closure to “<i>On Zero‐Inertia and Kinematic Waves</i>” by Nikolaos D. Katopodes (November, 1982)
Publisher: American Society of Civil Engineers
Observability of Surface Irrigation Advance
Publisher: American Society of Civil Engineers
Abstract: The conditions of observability and field‐parameter identifiability for surface irrigation advance are examined by analytical' techniques and the linearized zero‐inertia model. The existence and uniqueness of the inverse ...
Discussion of “<i>Asymptotic Solution for Dam‐Break Problem</i>” by Bruce Hunt (January, 1982)
Publisher: American Society of Civil Engineers
Site and Size Optimization of Contaminant Sources in Surface Water Systems
Publisher: American Society of Civil Engineers
Abstract: A numerical method is developed to minimize the environmental impact of one or multiple contaminant point sources in a vertically mixed river or estuary. The algorithm is based on a finite-element solution of the adjoint ...
Identification of Stream Dispersion Coefficients by Adjoint Sensitivity Method
Publisher: American Society of Civil Engineers
Abstract: A numerical technique is presented for identification of spatially distributed dispersion coefficients for 2D mass transport in vertically mixed rivers and estuaries. The method is based on a nonlinear optimization procedure ...
Control of Contaminant Releases in Rivers. II: Optimal Design
Publisher: American Society of Civil Engineers
Abstract: A numerical method is developed for the optimal design of contaminant releases in shallow rivers and estuaries. The algorithm is based on the hypothesis that the control action, at one or more points of release, can be ...
