Exfiltration Trench Design as Part of a Stormwater Management Plan
The paper discusses a program structured to assist the design consultant or the agency reviewer by means of a menu driven format. A flood routing microcomputer program developed by the...
Data Acquisition in USACRREL'S Flume Facility
A computerized data acquisition system has been developed that is based on a Hewlett-Packard 9845B desktop computer. The system allows determination of highly accurate water temperatures,...
3-D Orthogonal Curvilinear Circulation Modelling
A three-dimensional circulation model has been developed using an orthogonal curvilinear coordinate system. The model as constructed is capable of simulations on a variety of time and...
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...
Karnafuli Hydroelectric Project, Hydraulic Model Studies of Spillway Damage
The Karnafuli Hydroelectric Project is located in Bangladesh. On August 13, 1961, distress was noted in the spillway flow. A special Board of Consultants considered possible causes for...
Make-up and Blowdown of a Cooling Pond
A mathematical model was developed to simulate the operation of a recirculating cooling pond for a planned nuclear power plant in the Midwest. The objective of the pond operation is to...
An Infiltration Based Runoff Model For Use With a Design Store
The feasibility of using an infiltration approach for routine runoff prediction has become a reality with the development of approximate infiltration models based on physical principles...
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...
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...
Incorporating 3-D Effects into a 2-D Model
Some three-dimensional (3-D) effects may be incorporated into vertically averaged two-dimensional models. This is demonstrated with a case study where the effects of a complex system of...
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...
Urban Hydrology for Small Watersheds (TR-55 Rev.)
A microcomputer program is being prepared for the upcoming revision of the Soil Conservation Service's 'Urban Hydrology for Small Watersheds,' Technical...
A Quick Micro-Computer Urban Runoff Model
The Penn State Direct Hydrograph Model PSDH described in this paper uses watershed and rainfall data to generate a synthetic unit hydrograph and a runoff hydrograph, both gamma-distributed....
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'...
A Low-Cost, Microcomputer-Based Field Data Acquisition System
This paper discusses the selection and development of a micro-computer-based data acquisition system used for collecting aquifer test data. Primary components of the data collection system...
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...
