Estimation of High Spring Floods Causing Inundation in Non-Studied Rivers of the West Siberian Plain
Spring flooding is the main and the most abounding in water period in flow regime of West Siberian rivers. As a result, there is powerful and wide inundation on relief of West Siberia....
Direct Measurement of Turbulence Structures in a Standard Jar Test Tank Using PIV System
Particle image velocimetry (PIV) is applied to the measurement of instantaneous two-dimensional velocity fields in a standard 2-liter jar test tank for several different impeller speeds....
Accessible Information
As the amount of data relating to U.S. environmental policy grows, geographic information systems and advanced visualization system technology are being applied extensively to site investigations...
Non-Linear Solution Methods for Shell and Spatial Structures
Non-linear solution methods are investigated for the analysis of shell and spatial structures based on limited memory quasi-Newton updates. Under the proposed implementation the preconditioned...
The Effects of Spatial Resolution in Modeling the North Fork Drainage of the Gunnison River Basin
The U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) is a modular, distributed-parameter, watershed modeling system developed for use in evaluating the effects of climate...
Integration of Water Quantity and Quality Planning
This paper describes the integration of water quantity and quality objectives within the framework of a computerized interface design to assist with the difficult process of long-range...
TIGER and Census Bureau Data in a GIS: A Powerful Combination for Civil Engineers
TIGER is the acronym the Census Bureau crated to identify its computerized geographic support system: the Topologically Integrated Geographic Encoding and Referencing System. Although...
3-D Coordinates - A Universal Rectangular Coordinate System for a GIS and Other Spatial Databases
Rules of solid geometry and 3-dimensional (3-D) rectangular coordinate systems are well known and used in many applications. Points on or near the earth's surface have long been described...
Overflow Elimination Benefits from GIS Based Technology
Elimination of wet weather overflows through the rehabilitation of infiltration and inflow defects requires careful analysis of the collection system. The integration of geographic information...
Time-Space Tradeoff Strategies for Space-Schedule Construction
Space availability on a construction site can have a major impact on the efficiency and constructability of a project. Especially when space is limited, tradeoffs between activity sequencing,...
Extended Topology in Building Design Systems
An important aspect of CAD systems for building design concerns the description of the form of the building, the definition of operation on that form and the way these operations are offered...
Observations on the Growth of an Internal Boundary Layer with a Lidar Technique
The distribution of atmospheric water vapor across a step change in surface humidity (dry-wet) was observed by a Lidar measurement technique under neutral atmospheric stability condition....
Some Benefits of Grid by Number Sampling
Describing the overall sediment composition of gravel-bed river reaches and depositional bars is a difficult problem due to spatial variations in the sediment size. Past research has focused...
Temporal and Spatial Variations of Suspended Sediment Concentration during Navigation Traffic in a Natural River
Suspended sediment samples were collected within the channel border area during barge-tow passage events at three cross-sectional locations on the Upper Mississippi River. Typical plots...
Use of Geographic Information System for Transportation Data Analysis
Origin-destination (O-D) survey data have been usually applied to identify travel characteristics for transportation planning activities. Travel forecasting models are also validated against...
Building Separation Rules to Avoid Seismic Pounding
A method to estimate the required separation to preclude pounding between adjacent buildings is presented. It accounts for the effect of yielding on the vibration phase of adjacent buildings....
Data Base for Seismis Rick Assessment in Mexico City
We describe a model to estimate expected ground motions and expected damage, based on intensity damage relations derived for 14 classes of buildings representative of Mexico City construction....
The Best of Both Worlds: Integrating Statistical and Deterministic Approaches to Area Remediation
We seek a complete framework for adaptive area characterization for purposes of remediation, incorporating both statistical and deterministic features. This hybrid methodology involves...
Impact of Spatial and Temporal Data Limitations on the Modeling of Runoff Quantity and Quality
A small subbasin within an urbanized watershed (Reno, Nevada) was intensively monitored for runoff quantity and quality. The EPA Stormwater Management Model (SWMM) was applied to simulate...
Real-Time Position Measurement Integrated with CAD-CAE and Related Data Structure Issues
The Civil Engineering Research Foundation (CERF), Bechtel Corp. (Bechtel), Jacobus Technology, Inc (Jacobus), and Spatial Positioning Systems,Inc. (SPSi) have formed the Consortium for...
