An international symposium on
Effects of Spatial Data Resolution and Subarea Size on a Distributed Runoff Model
Spatial data layers of elevation, land use, and soils for a small agricultural watershed in Pennsylvania were used to study the effect of resolution degradation of raster data on the output...
Development of a Hydrologic Model with Both Spatially Distributed and Physically Based Capabilities
A distributed hydrologic model is developed at The Pennsylvania State University for use with rasterized data bases. The purpose of the Terrestrial Hydrologic Model or THM is to investigate...
Real-Time Construction Staking
Surveying has changed from a profession in which one learned skills on the job and could even become licensed without a degree. Now firms are turning to high tech equipment using geographic...
The Kinematic Design of a Robotic Large Space Structure Construction Service
Researchers at the University of Maryland's Robotics Research Lab are applying a kinematic rapid proto-typing methodology to the development of a commercial robotics service for the construction...
Effects of Force Reflection on Telerobotic Performance
The University of Kansas Augmented Telerobotics Laboratory conducted a study to examine the effects of force reflection on telerobotic system and operator performance in performing two...
Nonlinear Decomposition of a 2-D Wave Field
Based on an understanding of nonlinear wave interaction in dual component wave, a new numerical scheme allowing for hybrid wave-mode modeling has been developed. in the hybrid wave-mode...
Second Order Directional Wave Kinematics in Shallow Water
A theory numerical procedure were developed earlier to represent a real sea by the sum of many linear and second order directional wave components. Earlier publications showed that including...
Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...
Hydraulic Properties of Surface Runoff on Ash-Mixed Concrete Pavement
The disposal of incinerated sludge ash from wastewater treatment plants is becoming an increasingly difficult problem in highly populated cities. The feasibility of reusing sludge ash...
Optimal Operation of Soil Aquifer Treatment System
Mathematical models based on nonlinear programming are developed for operating soil aquifer treatment(SAT) systems. The objective of these optimization models is to determine the operation...
Sheet Flow Resistance of Asphaltic Pavements
A statistical study has been conducted by the authors using 400 points of experimental data taken in the 1970's at Texas A&M for sheet flow runoff during artificial rainfall on...
GPS Goes Real Time
This paper discusses the feasibility of Trimble Navigation's Site Surveyor System using Real-Time Kinematic (RTK) technology for conducting cadastral surveys. The use of RTK...
A New Theory of Built-Up Columns
In laced, battened and other built up columns the shear stiffness of the web can have a significant effect on the overall buckling load. At the present time, such columns are analyzed...
Optimum Operation of Recharge Basins
Mathematical models based on nonlinear programming are developed for operating recharge basin systems. The objective of these optimization models is to determine the operation policy that...
Hydrologic Modelling of Extreme Flood on Small Mountainous Watersheds
Statistical and deterministic methods for extreme flood estimation were applied to Swiss alpine catchments to assess the application limits of each approach. Comparative results produced...
Kinematic Mixing in Stratified Aquifers
The mixing process in heterogeneous aquifers is presented as the bending and stretching of material lines. A linear mixing efficiency is defined in terms of the mean values of a unit length...
Manning's n From Experiments with Rainfall-Runoff on Portland Cement Concrete Surfaces
Experiments were conducted under artificial rainfall on Portland cement concrete (PCC) surfaces with variable mean texture depths (MTD) and slopes (S). Rain rates were varied up to 3 in/hr...
