Prescribed Solution Forcing Method for Model Verification
This paper describes a method for verifying the consistency and order of accuracy of a numerical implementation of a pde-model. We present an example of its application to a 3D hydrodynamic...
Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...
3-D Free Surface Flow Model Verification
This paper is intended to achieve two objectives: (1) providing the readers and participants of the 1991 ASCE National Conference on Hydraulic Engineering with background information about...
Use of Electronic Microprocessor-Based Instrumentation by the U.S. Geological Survey for Hydrologic Data Collection
The U.S. Geological Survey is acquiring a new generation of field computers and communications software to support hydrologic data-collection at field locations. The new computer hardware...
Data Acquisition Techniques for Rotating Machinery
Monitoring the condition and performance of a hydraulic turbine or pump requires the simultaneous collection of data related to shaft speed, torque, power, water and airborne sound pressure...
Computerized Hydraulic Modeling?A Case Study
A hydraulic model study is being conducted at the Alden Research Laboratory, Inc. (ARL), to study the effects of adding a hydroelectric generating station at the site of an existing lock...
Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...
Data Acquisition for Hydrologic GIS
Various data acquisition options for hydrologic oriented GIS are presented. These options include manual digitizing, commercial digital data, satellite products, and automated scanning....
Two-Dimensional Hydrodynamic Modeling of a Reach of the Mississippi River in Pool 19
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area...
A Knowledge Based System for Design of Localized Mechanical Mixing Systems
Knowledge-based systems, frequently referred to as expert systems, have been used in a variety of computer-based design applications. They are particularly suited to design processes where...
Verification of Clark County Hydrologic Modeling
The Clark County Regional Flood Control District, which includes the Las Vegas, Nevada metropolitan area, has recently adopted hydrologic criteria which are intended to standardize the...
A Dynamic Runoff Model for Disturbed Hillslopes
A dynamic runoff model is developed for use in analyzing the hydrologic response of disturbed hillslopes. The model employs an explicit form of the Green-Ampt equation which is coupled...
Combined Application of HEC-1 and HEC-2 Simulation Models in Dike Safety Analysis
The potential flood impact of a breach in a dike for a large spreading-area on a nearby waste storage facility was investigated. An HEC-1 model was used for generating breach hydrographs...
Daily Drought Monitoring by the Use of Existing Hydrologic Records
To manage water efficiently in case of drought, an effective drought monitoring method has been of interest. Drought durations and their conditional probabilities are estimated by applying...
Sedimentation Aspects of Floodplain Management
This paper presents sedimentation aspects of a recent disastrous flood that occurred during September 10-12 1990 in the Han River basin, a central part of the Korean peninsula. The flood...
Cofferdam Rip-Rap Protection for the New Esna Barrage
A 1:60 undistorted mobile bed model of the Nile River in the vicinity of Esna Barrage was constructed at the Hydraulics and Sediment Research Institute to test rip-rap protection of the...
Development of Crop Coefficients Using Lysimeters
A long term record of evapotranspiration by grass as measured with the large weighing lysimeter at the University of California at Davis provided an excellent background for the initiation...
Automation of a Truck-Mounted Drill Rig
Truck-mounted drill rigs used for soils properties investigation, foundation evaluation, ore exploration, and producing monitor and water wells typically require, because of their weight,...
Effect of Gas Flow on Physical Absorption
Air blowing over a liquid surface can greatly increase the rate of physical absorption of a gaseous component. This increase is associated with the initiation of waves and a change in...
