An Advanced First-Order Method for System Reliability
This paper proposes an iterative first-order method for accurate estimation of the joint failure region of two nonlinear limit states. Current methods use either a first-order approach...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
A Two-Stage Safety Assessment Methodology for Construction Activities
The control of construction activities requires the evaluation of the condition of the control attributes of interest. In order to develop the required methodology, a model of the construction...
Environmental Impacts of Agricultural Drainage
Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow...
Tapping Shallow Groundwater with Horizontal Wells
In recent years, horizontal wells have become an economical water supply source alternative for many shallow water table areas in Florida. Horizontal wells typically utilize 15 to 20 cm...
Holistic Approach to Irrigation Management in Developing Countries
Sound development of irrigation and drainage projects in developing countries is a continuing need to reduce hunger, environmental degradation and excess population growth; and to promote...
Progress Report ARS/SCS Runoff Curve Number Work Group
The Soil Conservation Service (SCS) Runoff Curve Number (RCN) procedure works well as a single event model to estimate design storm runoff volumes from a small agricultural watershed....
Hydrogeotechnical Considerations for the Disposal of Oil Shale Solid Waste Material
Laboratory tests and five large scale lysimeters (7.3?3.0?3.0 m deep) have been constructed to collect information and data on hydrogeotechnical factors which affect an oil shale solid...
Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...
Assessing the Leaching Potential of Herbicides at the Ohio MSEA
The GLEAMS model was used to assess the potential for herbicide leaching at the Ohio MSEA. Input data, typical of the Ohio MSEA, was used in conjunction with precipitation data for the...
Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
Management of Agricultural Drainage Pollution Considering Regional Cooperation
Increasing awareness of toxic substance discharge from agriculture in the San Joaquin Valley of California has resulted in discharge limits on individual constituents in agricultural drainage....
Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...
