Two-Dimensional Modelling of Flow in the River Sava
On the river Sava near Ljubljana, a sports centre with a kayak racing channel was built in 1948. For the world championship in kayak-canoe racing in 1990 totally new racing channel had...
Flood Propagation on Mobile Beds under Mountainous Flow Conditions
An implicit finite-volume scheme is used to solve the shallow water equations under mountainous flow conditions. The algorithm is stable for sub- and supercritical flows and moving internal...
A Computerized Open Channel Flow Measurement Device
This is a technical information paper with the intention of introducing a new product. It is not the intent of the author to use this as a marketing tool. However, it is the intent to...
Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...
Hot-Film Response in Three-Dimensional Highly Turbulent Flows
A methodology is described for accurate turbulence measurements with hot film or hot wires even at turbulent intensities as high as 100%. The assumptions involved and the approximations...
A Two-Dimensional Contaminant Transport Model with High-Resolution Upwind Schemes
High-resolution upwind schemes have become popular techniques to solve multidimensional transport problems. Based on the finite volume method (FVM), two-dimensional horizontal hydrodynamic...
Hydrodynamic Modeling of San Diego Bay
A two-dimensional vertically-averaged finite element model was adapted to study the hydrodynamics of San Diego Bay. The hydrodynamic model was interfaced with pre- and post-processors...
Multi-Reservoir Systems Optimization by the Aggregation/Decomposition Methodology
Studies on long term optimization of multi-reservoir systems are enhanced by the availability of closed-loop policies as available in Stochastic Dynamic Programming (SDP). SDP offers a...
Modeling 3-D Ground Water Mounding
Groundwater mounding is caused by localized recharge to the saturated zone in an unconfined aquifer. Estimation of groundwater mounding shape and height is important to provide an estimate...
Development of Transport Model for Groundwater Planning and Management in Taipei Basin
The objective of this paper is to develop a groundwater model for contaminant transport simulation. The transport model, in conjunction with the previously developed flow model, is used...
Modeling of Maximum Velocity in Open-Channel Flow
A great deal of information about an open channel flow is contained in the maximum velocity, which, along with the entropy parameter, can determine the mean velocity. Therefore, the maximum...
An Improved Design of Fishways Under High Variation of Headwater
For the purpose of mitigating environmental impact, it is necessary to build fish passing facilities for fish migration when a dam is constructed on a river. But when the headwater variation...
High-Resolution Upwind Schemes for Solving Mass Transport Equation
A fractional-step algorithm is employed to solve the mass transport equation by decomposing the advection-dispersion equation into two portions, pure advection and pure dispersion. High-resolution...
Numerical Simulation of One Dimensional Transcritical Flow
The term transcritical flow describes the existence of both subcritical and supercritical flow simultaneously within the computational domain. Transcritical flow situations are encountered...
Depth-Averaged Flow Model in Curvilinear Coordinates
Implementation of a depth-averaged model in orthogonal curvilinear coordinates permits to resolve questions about grid refinement, the representation of complicated boundaries, and the...
Treatment of Nonhomogeneous Terms in Flow Models
A study of the relative significance and treatment of nonhomogeneous terms in unsteady open-channel flow simulation models has been conducted. The effects of nonhomogeneous terms including...
Use of a Modified Hybrid Model to Analyze the Effectiveness of Jetties in Reducing Marina Sedimentation
The effectiveness of the construction of jetties near the entrance channel of a coastal marina in reducing marina sedimentation has been analyzed using a modified hybrid model. The modified...
