Restoration of Abandoned Meanders on the Middle Fork Forked Deer River, Tennessee
The Middle Fork Forked Deer River in western Tennessee historically had a sinuous course within a wide floodplain. In the early 1900's, local interests dug large straight...
SAMS: Software for Simulating Streamflow Series
This paper introduces SAMS, a computer software developed for the analysis, modeling, and generation of hydrologic time series such as annual and monthly streamfiows. It is written in...
Verification of a 3D Flow Model Using Laboratory Data
The ASCE Task Sub-Committee on 3D Free Surface Flow Model Veri fications has been developing test cases and/or procedures for both computational model developers and users over the past...
Simulation of Dissolved Oxygen in Sacramento-San Joaquin Delta
A one-dimensional model has been developed to simulate water quality in a complex multi-channel estuarine system. The model utilizes a Lagrangian reference frame for transport computations....
Increasing Computational Accuracy of Radial Gate Flows
Radial (Tainter) gates are the most widely used flow control structure on large, open channel conveyance systems. In contrast, the hydraulic forces are complicated and this type of gate...
Field Determination of Flow through a Pressure Regulating Valve
This paper presents a computer methodology to calculate flow through a pressure regulating valve for different opening percentages and a given pressure differential. The methodology is...
Evaluating Hydraulic Roughness in Tunnels
Much of the data presented in the literature on measured friction losses in tunnels are given in terms of the Darcy-Weisbach
A New Technique for Measuring Vegetation Density
Detennination of the discharge capacity of a vegetated channel or floodplain requires a reasonable estimate of a flow resistance coefficient; such as Manning'
Numerical Simulation of Bridge Abutment Scour Development
This paper reports a project to simulate the development of a local scour hole around a bridge abutment by a computational model. From the prelim inary results obtained, it may be concluded...
Data Analysis for Computer Modeling of Thermal Discharges
Assessment of the thermal discharge impact upon the environment and design of the appropriate discharge structure necessitate a range of data activities, from extensive field measurements,...
The HEC NexGen Software Development Project
The NexGen project is developing successor software packages to the existing family of HEC computer programs. Development is occurring via teams comprised of technical specialists, computer...
Hydrologic Modeling System
The Hydrologic Modeling System (HEC-HMS) is new-generation software for precipitation-runoff simulation that will supersede the Hydrologic Engineering Centefs HEC-l program. Technical...
Next Generation Flood Damage Analysis Program
The Hydrologic Engineering Center has developed a next generation Flood Damage Analysis computer program for formulating and evaluating flood damage reduction plans. The program design...
Hydraulic Model Study of the Prado Dam Spillway
The existing Prado Dam, located in the City of Corona, CA, is deficient in providing adequate flood protection to the Santa Ana River floodplain downstream of the dam. To provide adequate...
Irrigation of Grain Sorghum on the Delmarva Peninsula
Irrigated grain sorghum experiments were conducted for two years on a Norfolk sandy loam soil. Full irrigation was compared to partial irrigation and no irrigation in a randomized block...
Karst Water Inventories Using Thermography
An airborne thermal camera was used to locate springs, swallets, and caves in a karst watershed. The detector was an imaging infrared camera with a temperature sensitivity of approximately...
Designing Concrete Culverts to Resist Scour Damage
Concrete culverts have been used for over 100 years. In this period, the main design concern centered on structural and hydraulic adequacy of the culvert. Scour is a relatively recent...
Effect of Pump-Ins on California Aqueduct Water Quality
A model has been developed, based on the assumption of constant Aqueduct volume, to predict the effect of ground water pump-ins on Aqueduct water quality. Designated SuperCAMP (California...
Numerical Simulation of Hydraulic Jump
Hydraulic jump is numerically simulated by solving the laterally-averaged governing equations. The governing equations are derived for two-dimensional flow by laterally averaging the time...
Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...
