Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...
Experimental Studies to Calibrate Unsaturated Flow Models
Work is described that has been designed to serve as a laboratory calibration of numerical models for unsaturated flow studies. The experiment size is configured large enough that the...
Lower Missouri River Water Quality Model for Evaluating Flow Alterations
A modified version of the US Environmental Protection Agency's (USEPA) one-dimensional (longitudinal) stream water quality model, QUAL2E, was applied to the lower Missouri River to evaluate...
Mean Areal Precipitation Estimation Using Radar
The accuracy of mean areal total storm precipitation (MAP) over small urban basins (30-100 km2) in the Denver, CO metro region was examined using...
3D-Simulation of the Twin Lake Tracer Test
The 1983 Twin Lake tracer test was simulated using a three-dimensional finite element model. The model was calibrated comparing calculated and measured piezometric heads as well as vertical...
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...
Global Search Technique to Calibrate Rainfall Runoff Models
The calibration of rainfall-runoff models in hydrology has not yet reached a satisfactory solution, using either manual or automatic procedures. This paper introduces a simple conceptual...
FLUME 3.0: A Computer Program for Designing Flumes and Weirs
Long-throated flumes and broad-crested weirs are becoming the preferred measuring devices for use in irrigation canals. A computer program for calibrating these flumes and weirs has been...
The ASCE Neutron Probe Calibration Study: Overview
A workshop was held at Logan, Utah to gather field information on neutron probe calibration and operation. Several techniques and instruments were compared. This paper serves to establish...
Soil Bulk Density Sampling for Neutron Gauge Calibration
The ASCE Task Committee on Neutron Gauge Calibration met in Logan, Utah in July 1992 to investigate the various methods of soil sampling, installation of access tubes, effect of various...
Measuring Soil Bulk Density Profiles with a Single Probe Gamma Density Gauge
Calibrating neutron depth gauges for measuring soil water content profiles requires soil bulk density data. In this study, the feasibility of using a single probe gamma density gauge to...
Error Analysis of Bulk Density Measurements for Neutron Moisture Gauge Calibration
Six bulk density sampling methods were evaluated for use in neutron gauge calibration. All six methods provided estimates of bulk density which were generally within 5% of bulk density...
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...
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...
