Groins and Vanes Developed Basing Upon a New Concept of Bank Protection
At curved bends, scour at the outer bank always accompanies deposition at the inner bank. A highly efficient river course for flood flow is considered to have a small lateral gradient...
Estuarine Mud Flow Modeling
This paper presents a model for the simulation of selective withdrawal of estuarine mud. This research is part of the investigation of the design of a mud pumping plant as an alternative...
Numerical Model Studies of Wetland Hydraulics for Bolsa Bay, California
The Bolsa Bay area, near Los Angeles, presently consists of three distinct regions separated by two sets of culverts. A development is being considered, in which a balance between housing...
Improved Numerical Analysis of Steady Water Surface Profiles
As well as HEC-2 and similar models serve the profession, problems exist with their application. In general, inflexibility of use and inaccuracies around transitions between subcritical...
Determining River Stages with Consideration of Backwater Effects
In a recent hydraulic investigation on the Cache River basin, the stages of the Mississippi River at the Beechridge station were found to be necessary downstream boundary conditions for...
Numerical Modeling of Hydraulic Jump
Boussinesq equations describing one-dimensional unsteady, rapidly varied flows are numerically integrated by using a second-order and a fourth-order accurate explicit finite-difference...
General Formulation of Best Hydraulic Channel Section
The best hydraulic channel section is determined by using Lagrange's method of undetermined multipliers. The approach presented is more general & easier to apply than...
Bank Protection at the Middle and Lower Yangtze
The Middle and Lower Yangtze runs through alluvial plains about 1800 km. There are mainly three types of river reaches: straight-slightly sinuous, meandering, and braided. This paper outlines...
Bank Erosion: A Review of British Research
The paper summarizes recent contributions from British geomorphologists and hydrologists. This includes field measurements of processes, modeling of corrasion and mass failure, interactions...
Control of Bank Erosion in The Netherlands. State-of-the-art
In the Netherlands the protection against flooding and the effects of inland navigation have always been extremely important. Many problems related to these items, among them erosion and...
The Turbulent Wake of a Recirculating Eddy in Shallow Waters
The wake, created by injecting dye into the recirculating zone of a sudden lateral expansion in a shallow open channel, is examined experimentally for a range of bed-friction influence....
Cellular Automaton Simulation of Viscous Free Surface Fluid Dynamics
It has been demonstrated elsewhere that the simple interaction of a two dimensional field of discrete particles traveling on a regular lattice yields large scale behavior closely approximating...
Performance Characteristics of Compound Weirs
A theory is outlined which helps to explain the flow over compound weir under free overfall conditions. Experiments on twelve weirs of three sets with different dimensions are shown to...
Analysis of Pumping Station and Force Main Networks
A computer program to simulate the performance of wastewater pumping station and force main networks is discussed. Results are presented which compare system performance for steady and...
Relief of an Urban Storm Drainage System
The Peaks Branch storm sewer system was designed in the 1930s to drain 5.7 square miles of East Dallas. Subsequently, development blocked the emergency overflow paths and many areas are...
Analysis of Storm Sewers During Surcharge
A mathematical model based on a lumped system approach is presented to simulate unsteady flow in storm sewers during surcharge. The model equations and method of solution are presented....
Verification of Local Modes in a Two-Dimensional Tidal Model
Based on a generalized model equation, a two-dimensional hybrid finite element model has been developed to study tidal waves of incompressible, homogeneous fluid in rotational flows. In...
Convergence Experiments with a Hydrodynamic Model of Port Royal Sound, South Carolina
A two-demensional, depth-averaged, finite-difference, flow/transport model, SIM2D, is being used to simulate tidal circulation and transport in the Port Royal Sound, South Carolina, estuarine...
SWMM Application in Indian River County, Florida
The EPA's Storm Water Management Model (SWMM) was used to simulate drainage canal system network within Indian River County, Florida. Runoff and Extran module of the PCSWMM...
Implementation of a Hydrodynamic Model for the Upper Potomac Estuary
A vertically integrated, two-dimensional hydrodynamic/transport model has been implemented for the upper extent of the Potomac Estuary between Indian Head and Morgantown, Md. The model...
