Two-Dimensional Flow Visualization Using the Vortex Computer Code
A computer code has been developed to provide visualization of flow fields with regard to many hydraulic engineering design and analysis problems. The finite-difference computer code VORTEX...
Hydraulic Study Requirements for Bulb Type Hydropower Units at a Navigation Lock and Dam
A replacement Lock and Dam at Alton, Illinois on the Mississippi River is presently under construction. This paper presents the results of studies performed for adding six bulb type hydropower...
Unique Utilization of a Physical Model to Develop a Construction Sequence of a Major Cofferdam
Lock and Dam 26 Replacement is being constructed on the Mississippi River about 2 miles downstream of the existing Locks and Dam No. 26 at Alton, Illinois. This paper discusses the unique...
A Microcomputer Program for River Sedimentation
Erosion and deposition of sediment in rivers causes numerous problems. In order to describe this process, both the hydraulic properties of the river and the mechanics of sediment transport...
Secondary Circulation Data Acquisition System
A computerized field data collection system was developed for a project investigating secondary circulation in natural rivers. The instrumentation includes a Commodore mini-computer with...
Landfill Liner Hydraulics for Microcomputers
Two different models are presented for the study of sloping bottom liners for landfills. The first is based on the assumption that the leachate volume is uniformly distributed over the...
The Micro vs. Mainframe in Hydrologic Modeling and Forecasting
This paper describes and compares the performance, application, and suitability of a microcomputer as host for the large-scale hydrologic model called SSARR. The SSARR Model is currently...
Flood Routing Through Rock Dumps in Natural Channels
The paper deals with flow through rockfill to analyze the problem of flood routing through large masses of waste rock from mining operations dumped in natural channels. Rock dumps in ephemerous...
Water System Analysis?Modeling Hydraulics
The work described in this paper is part of the planning and design effort for expanding and improving the water supply system for St. John the Baptist Parish, Louisiana. The parish is...
The U.S.G.S. Modular Ground-Water Flow Model: Designed to be Understood and Adapted
The paper discusses a carefully designed model program and its complementary complete description of all of the physical and mathematical concepts used in the model. The model program...
Applicability of Groundwater Models to Microcomputers
Microcomputers represent a viable alternative to mainframe and minicomputers for the implementation of groundwater models. The criteria used to evaluate microprocessors are maximum addressable...
Three-Dimensional Simulation of Two-Fluid Movement in Porous Media Using the Boundary Element Method
The paper discusses three-dimensional problems that include a denser fluid overlain by water in an unconfined aquifer. The two fluid regions are bounded by two-dimensional surfaces, including...
Generation of Steady Density Currents Through Boundary Layer Control
The paper reports on a study to explore the conditions that trigger bifurcation of ambient flow/intrusion interaction into one of two drastically different regimes, i. e. current versus...
Hydraulics of Broad Crested Weirs
The paper presents a general, basic discussion of the title subject. It begins with a definition for the broad crested weir and analytical concepts. Subjects covered subsequently include...
Velocity Distribution Factor Constraints
It has been customary to introduce the velocity distribution factors alpha and beta into the energy and momentum equations so as to avoid the integration associated with variations in...
Automated Measurement of Soil/Water Properties
An automated data-acquisition system was constructed to permit continuous operation of laboratory equipment. The apparatus was used to monitor flow through fine-grained, 'undisturbed'...
Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
Tidal Modelling on IBM Microcomputers
The finite element code, QUIET, for the simulation of two-dimensional shallow water flow has been adapted from its mainframe form for use on the IBM PC, PC/XT, or AT. The model uses of...
