IRSIS, A Software Package for Irrigation Scheduling
IRSIS (IRrigation Scheduling Information System) has been developed to solve problems concerning irrigation scheduling at field level. For a given climate, crop and field it offers the...
Optimal Real-Time Pump and Irrigation Scheduling for Center-Pivot Sprinkler Systems
A comprehensive scheduling algorithm is presented for optimally integrating irrigation and pump operational decisions in center-pivot sprinkler systems. Dynamic programming successive...
A Tale of Two Subjects: Modern Physics and River Mechanics
The Einsteins, father and son, made some of the greatest contributions to physics and to river mechanics, respectively. The modern phases of these two subjects are of roughly equal age....
Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...
Engineering Models for Coastal Sediment Transport
During the last ten years Danish Hydraulic Institute (DHI) has together with the Institute of Hydrodynamics and Hydraulic Engineering (ISVA) of the Technical University of Denmark been...
Erosion and Sedimentation Research in ARS
The paper presents a brief history of the growth of the erosion and sedimentation research program in the Agricultural Research Service of the U.S. Department of Agriculture. Subjects...
Corps of Engineers' Mississippi River Sediment Studies
In conjunction with the 1838 U.S. Army Corps of Engineers hydrographic survey of the Mississippi River, CPT A. Talcott collected sediment samples in the passes 'to determine...
Implications of Deep Ocean Modelling on Coastal Sedimentation Prediction
The Harvard University Ocean Predictive Descriptive System is reviewed and recent results of mesoscale ocean prediction are presented for the Northeast Pacific and Gulf Stream Ring Stream...
The Relationship of Milligrams Per Liter to Parts Per Million
Derivations of the relationships between mg/l and ppm are presented. Although forms of these relationships can be found in scattered references, the author's intent is to...
Limitations of Modeling High Concentration Streams
Following the 1980 eruption of Mount St. Helens, high sediment concentrations caused rapid deposition and increased flood hazards along the Cowlitz River. The Corps of Engineers developed...
Bank Failure and Erosion on the Illinois Waterway
In 1988, bank failure and erosion on the Illinois Waterway were evaluated. Banks were inspected from the air and from a motor vessel; thirty-one sites were examined in detail. Severe erosion...
Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...

Bullwinkle
The 1989 Outstanding Civil Engineering Achievement is an offshore oil production platform named Bullwinkle, a structure in the Gulf of Mexico that is taller than the Sears Tower, shaped...
Award for an A-Frame
The Waddell A-frame truss bridge that now stands in Parkville, Mo. was neither the longest, largest nor most all-encompassing civil engineering project of 1988. But the story behind the...
Geotechnical Aspects of River Bank Erosion
The principal geotechnical mechanisms of river bank failure are identified on the basis of extensive field investigations on many different river systems. The role of each factor depends...
Control of Bank Erosion in The Netherlands. State-of-the-art
In the Netherlands the protection against flooding and the effects of inland navigation have always been extremely important. Many problems related to these items, among them erosion and...
Modeling Variations in Soil Moisture and Streamflow Resulting from Climatic and Land Use Changes
A distributed parameter watershed model IWASCH has been developed to simulate variation in soil moisture and baseflow conditions for agricultural areas in Illinois, resulting from climatic...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
GEOPACK: A Geostatistical Software System
A comprehensive, user-friendly geostatistical software system called GEOPACK has been developed. The purpose of this software is to make available the programs necessary to undertake a...
