Neutron Gauge Calibration Comparison of Methods
Several methods for obtaining soil samples for determining soil water content were used for field calibration of neutron gauges. This paper compares the results of calibration curves obtained...

Effect of Moisture and Bulk Density Sampling on Neutron Moisture Gauge Calibration
Three moisture and bulk density sampling methods were evaluated for use in neutron gauge calibration. Each of the methods was comprised of a single core or portions of a core taken during...

Development of San Gorgonio Pass Groundwater Flow Model I. Model Calibration
A groundwater flow model is being developed for use in management of a planned groundwater storage and recovery program for the Beaumont Storage Unit of the San Gorgonio Pass groundwater...

The DWR Delta Data Assembly Project
While much progress has been made in advancing the theoretical development of estuary models, relatively little effort has been made in improving the quality and quantity of historical...

Calibration of Manning's Roughness for a River Reach
The Albuquerque Projects Office of the U.S. Bureau of Reclamation collected water surface elevations for measured discharges for the Rio Grande and many of its tributaries to try to obtain...

Use of Floodplain PCB Concentrations to Calibrate a River Hydraulics Model
A river floodplain was found to contain measurable quantities of polychlorinated biphenyls (PCBs), presumably deposited during historic flood events. A hydraulic model (HEC-2) was used...

The Concept of Local Euler Number as an Aid for Sizing Pitot Tubes
Correlations with drag coefficients enable determining the relations between the form of Pitot tubes and their velocity coefficients. A numerical example is presented to clear the use...

Modeling Vertical Stratification in the Pamlico River Estuary Using Modern Hydrodynamics
A modern hydrodynamic model is applied to the Pamlico River estuary. Good agreement was obtained between measured and predicted water elevations and salinity distributions during the one...

On the Calibration of Hydrologic Models
A procedure is proposed to calibrate hydrologic models to generate representative design flows and flood hydrographs. This procedure includes two calibration steps; event calibration and...

Calibration of Hydrologic and Energy Production Models for High-head Low-flow Hydroelectric Plants

Limitations of Reduced Scale Testing on Parshall Flumes
A model for the boundary layer development in the entrance section of a Parshall flume is developed to account for the effects of fluid viscosity on flume calibration equations. Data for...

Verification of a Three-Dimensional Modeling in Apalachicola Bay

Numerical Modeling of Flow and Transport Phenomena in a Fractured Rock and Its Calibration Process

Computerized Transportation Planning Models for Site Impact Analysis: Precision or Complexity?
Computer based travel forecasting models are now being widely used in the analysis of the traffic impacts of proposed developments. They are commonly used to identify improvements needed...

Methodology for Validation of a Tampa Bay Circulation Model
The National Ocean Service is presently conducting the Tampa Bay Oceanography Project, including development and application of a three-dimensional circulation model to the Bay, and collection...

Calibration and Validation of the Storm Water Management Model to the Providence Area Combined Sewer System
This paper exemplifies the calibration and validation of the EPA Storm Water Management Model (SWMM) to one drainage area within the Providence (RI) area combined sewer overflow system....

Modeling Stormwater Basin Effects
This paper presents results of an extension to a study included earlier in these proceedings on the downstream accumulation effects of stormwater detention basins. The previously calibrated...

In-Flight Calibration of Mass Spectrometer
A new device for in-flight calibration of mass spectrometer is presented. At a ground station command the calibrator introduces a constant and reproducible amount of deuterium into the...

Development of the San Fernando Basin Groundwater Flow Model
This paper describes the development and calibration of the San Fernando Basin (SFB) groundwater flow model. The SFB is the largest groundwater basin in the Upper Los Angeles River Area...

Calibration of Redundancy Factors for Highway Bridges
The object of this study is to develop a framework for considering redundancy in design and load capacity evaluation of highway bridge superstructures. The proposed method consists of...
