Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
Landslides and Cherry Trees -- Upgrading the Dalles Irrigation District
The Dalles Irrigation District recently began the process of applying for a federal loan to finance upgrading of the District's distribution system. The process included preparation...
Effect of Saline Irrigation Water on Tree Growth
A random block experiment using three types of soil, five different qualities of irrigation water, and three popular windbreak trees was conducted to measure the effects of soil type and...
Bank Erosion During the 1988-Flood in the Rumoi River
Observations of the bank erosion were performed in the Rumoi River after the flood in August, 1988. It was found from the detailed research that the pattern of the flood was an important...
Suburban Superfund
Discovery of methane seeping into houses at a new development near Newark, Del. set off investigations that eventually led to the U.S. EPA declaring the site eligible for Superund cleanup...
Instream Flow Requirements for Riparian Vegetation
Increasing frequency of stream diversion is requiring establishment of methods to determine instream flow requirements for riparian resources. Most methods are oriented toward fisheries....
Selection of Jim Falls Turbine Generators
The selection of the unit configuration for the Northern States Power Company's Jim Falls Hydro Redevelopment Project was based on an extensive evaluation of various turbine...
The Political Science of Acid Rain
Emission control engineers must understand the politics and science of acid rain. Current research indicates that acid rain can be connected with lake acidification. But it can not be...
Development of a Monitoring Program and Vegetative Restoration Project in a Mississippi River Bendway
The Dry Bayou-Thompson Bend area is located on the right descending bank of the Mississippi River between river miles 4. 5 (7. 2 kilometers) and 30. 0 (48. 3 kilometers) above the confluence...
Evaluating Transit: The Performance Tree Method

Engineering a Corporate Statement
Frito-Lay National Headquarters, Plano, Tex., occupies a 218 acre site in a corporate office park that had been a cow pasture. It was unusual in having mature trees and a natural watercourse...
Integrated Wastewater and Sludge Treatment in a Tree Farm
A system which integrates land treatment of wastewater following primary sedimentation with tree production and sludge composting was evaluated for its land requirements, costs, and energy...
Hierarchical Substructuring for Adaptive Analysis
An algorithm for the automatic generation, from solid models, of finite element meshes organized as spatially addressable quaternary trees (for 2-D analysis) or octal trees (for 3-D analysis)...
Expert System for Risk Assessment of Concrete Dams
An expert system is presented that will assist a field inspector, during the site investigation of an existing concrete dam, to perform a preliminary structural risk assessment of the...
Modelling Transpiration of Subalpine Trees in the Central Rocky Mountains
Forest evapotranspiration (ET) has long been recognized to be a major component in the mass water balance of subalpine watersheds in the central Rocky Mountains. In recent years, research...
