The Journal of Hydrologic Engineering disseminates information on the development of new hydrologic methods, theories, and applications to current engineering problems. The journal publishes papers on...
Dredging Up the Past
Disposal of contaminated dredged materials has become a national problem. The nation's ports and harbors have postponed dredging because of the cost and difficulty in finding...
Cleanup Solution--Conflict Resolution
Distrust and misinformation often prevent timely resolution of ground-water contamination problems. In Toms River, N.J., engineers used a computer-generated model of the cleanup site in...
Is Virtual Reality for Real?
Virtual reality, an advanced visualization technology, will change certain aspects of civil engineering. The method allows people to simulate conditions, render designs and test these...
Stormwater Management Solution
Flash floods are a threat to both existing homes and future development in the Scottsdale, Ariz., area. Engineers studies various alternatives for effective stormwater management an weighed...

Money-Saving Model
Determining whether dams and spillways along a river are adequate to handle potential floods can have far-reaching financial, as well as human ramifications. Watershed modeling studies...
The Role of Computer Graphics in Teleoperation
Computer graphics techniques developed by the Advanced Teleoperation (ATOP) Project at the Jet Propulsion Laboratory (JPL) for the control of remote manipulators, primarily for space applications,...
Application of Virtual Reality to Space Robotics Operations
This paper discusses a Virtual Reality (VR) simulation under development by the Automation and Robotics (A&R) Division at the Johnson Space Center (JSC). Over the past twelve years,...
Recent Developments in the Robotic All Terrain Lunar Exploration Rover (RATLER) Program
The Robotic All-Terrain Lunar Exploration Rover (RATLER) is a four wheeled all-wheel-drive dual-body vehicle. A uniquely simple method of chassis articulation is employed which allows...
Enabler Chassis Features and Mobiltiy Analysis
The Enabler is a proposed Lunar Base work vehicle. The unique construction of the Enabler's six-wheeled chassis provides unusual articulation for steering, balancing, and overcoming obstacles....
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...
Bechtel Automated Lift Planning System
This paper describes the Automated Lift Planning System (ALPS) software developed by Bechtel Corporation. The software was developed to assist the construction engineer with planning and...
Improving Dynamic Finite Element Models Using Test Data
A structural optimization based method was developed to improve the finite element model to achieve good agreement with the test results. The modal displacements at critical locations...
Dynamic Analysis of a High Speed Transport Model by Using a Piecewise Continuous Timoshenko Beam Model
Conventional treatment of structural dynamic analysis and control is based on the finite element structural model. But such a treatment uses a very large number of elements which is usually...
Dynamics of Laminated Plates with Layer Waviness
Composite structures usually exhibit a high strength-to-weight ratio as compared to traditional structural materials. This makes them attractive solutions in many aerospace applications....
Thermal Response in Antenna Under Laser Irradiation
This investigation focuses on the thermal response of two objects under medium-intensity continuous-wave (CW) laser irradiation: (1) a homogeneous slab and (2) a complex electronic component,...
Damage Tolerance of Thin Composite Reinforced Membrane Structures
Structural performance of fiber reinforced flexible composite membranes, designed as pressurized shelters for space exploration, is investigated via computational simulation. An integrated...
Convergence Rates of the Method of Successive Elastic Solutions in Thermoplastic Problems of a Layered Concentric Cylinder
This paper examines convergence rates of the method of successive elastic solutions, proposed by Mendelson, in determining the thermoplastic response of an arbitrarily layered concentric...
