Effect of Santa Rosa Lake on Ground Water Flow to the Pecos River, New Mexico
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa...
Streamflow Losses, Consequent Flow Through a Thick Unsaturated Zone, and Recharge to an Unconfined Aquifer
Two experiments were conducted in conjunction with a 23-day aquifer test made in south-central Arizona to determine (1) water loss from a natural channel and (2) flow through a 330-foot-thick...
Scheduling in Manually Controlled Canal Irrigation Delivery Systems
The effects of canal transients on scheduling water delivery to an irrigated area are described using a linearized form of flow equation obtained from a zero-inertia momentum equation...
Modeling Flow in an Ephemeral Stream Channel
A particularly distinguishing characteristic of ephemeral streamflow is the large role played by infiltration. Infiltration interacts in a complex way with channel flow to control the...
Equilibrium Beach Profiles: Prediction of Coastal Erosion Due to Severe Storms
This paper describes a method that calculates coastal erosion due to severe storms. The equilibrium beach profile concept used in this study was developed by Swart. The agreement between...
Vanishing Beaches: Erosion Control & Public Policy
Currents, often remotely situated, divert the littoral supply which normally ensures a positive balance among factors preserving natural beach configurations. Artificial structures such...
Anadromous Fish Impacts at Proposed Hydroelectric Plants
This paper describes a series of field techniques successfully used by the authors to determine a minimum flow downstream of hydroelectric plants. The minimum flow of water required for...
Teaching Open Channel Design with Programmable Pocket Calculators
The goal of the basic open channel flow course is to present the theory of steady flow of water in open channels and some channel design practice. This paper presents the evolution of...
Hydropower Surveys with Microcomputers
A microcomputer program, HYFEAS, has been written in BASIC for use in pre-feasibility assessments of a given site. HYFEAS uses a flow duration curve, headwater and tailwater curves, information...
Microcomputer Simulation of Jets and Wakes
Illustrations are presented for radial jets and for turbulent flows in the wake of circular cylinders. The paper illustrates the use and importance of low-cost computational tools in engineering...
A 1-D Saltwater Intrusion Program on the IBM-PC
A one-dimensional finite element program has been developed for use on the IBM-PC as an aid to teaching groundwater hydrology to students. The program uses linear elements and the Galerkin...
Estimating Peak Flow Reduction in Small Reservoirs
A microcomputer program is used to provide a simple and rapid estimate of the peak outflow from such reservoirs. Peak flow values, determined by flood frequency analysis or regional flood...
Predicting Overland Flow and Infiltration
The kinematic overland flow and the Green-Ampt infiltration equations are coupled and rewritten in terms of several nondimensional parameters. Constant values of these parameters imply...
Computerized Information for Selecting Protected Streamflow
For developing criteria for protected flow (the flow below which water withdrawals for offstream uses are not permitted) for streams in a relatively hydrologically homogeneous region,...
Vertical Transport of Fine-Grained Sediments in Suspensions
Numerical-model sensitivity studies were made to determine the effect of bed flux on the vertical distribution of fine-grained material suspended in turbulent flow. The transport equation...
Simulating Flow in the Tidal Potomac River
A one-dimensional unsteady flow model has been applied to the tidal Potomac River, including its major tributaries and marginal embayments, between Washington, D. C. and Indian Head, Md....
Canal Discharge Impacts on Fahka Union Bay
The effect of a large drainage canal's discharge on Fahka Union Bay's value as a nursery ground for estuarine-dependent fish and shellfish, including commercially...
Numerical Modelling of Pollutant Transport from a Pond to a Stream
The problem of transport of pollutants in groundwater flow from a polluted shallow pond to a natural stream is considered. A numerical model predicting changes in quality of ground water...
Flowfield Analysis with a Workstation
An engineering analysis workstation has been developed to expedite flow analysis. The workstation couples a microcomputer, a powerful numerical equation solver, and a versatile graphics...
Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....
