Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
Computer Aided River Basin Management in the Alps
The present paper outlines progress in developing river basin management potential through joint research on several Alpine River Systems including the Avisio, Brenta, and Cordevole. Applications...
Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...
Continuous Modelling of Downstream River Erosion Caused by 40 Years of Urbanization
The US EPA Stormwater Management Model (SWMM3) was installed on an IBM-PC compatible network. The adapted program, known as PCSWMM3, and incorporating a simple algorithm for modelling...
Advection Calculations Using Spline Schemes
The calculation of advective transport in one and two dimensions is done by the method of characteristics using spline interpolating polynomials at the forward time step. The method has...
Hale Cycle and Indian Drought and Flood Area Indices
The Indian Drought (DAI) and flood (FAI) area indices have been argued to be related to the hale cycle of sunspot number by H. N. Bhalme and D. A. Mooley. They studied the dependence between...
Taming a Pipe Network Analysis Computer Program
The use of a conventional network analysis computer program as an effective evaluation tool for routine operation of an existing water distribution system has several practical limitations...
Energy Dissipation in Small Canals
Two approaches are used for energy dissipation in channels. In the first, the water is allowed to drop, thereby converting potential energy to kinetic energy. This excess energy is then...
Trash Busters ? A Comparison of Screening Structures for Irrigation Systems
Several irrigation districts in the Pacific Northwest have recently installed screening structures for use in removal of trash from canals, rivers, or reservoirs. Some of the screens have...
Geohydrologic Considerations in Ground Water Modeling
Ground water modeling is an effective engineering and management tool for evaluating complex hydrogeologic situations in a cost effective manner. Objectives of a particular study dictate...
Water Issues in Tropical and Sub-Tropical Australia
The Northern Territory and State of Queensland cover an area of 3. 1 million km**2 and encompass most of the tropical and sub-tropical zones of Australia. Surface and groundwater resources...
Water Supply and Sewage Disposal: Shanghai, China
This paper describes a joint research effort which took place between the Shanghai Bureau of Environmental Protection, Tsinghua University (Beijing), and the University of Michigan. The...
Design Criteria for Mass Culturing Spirulina Algae
One extract of Spirulina, developed by Dr. Christopher Hills has been used as a nutrient for cell cultures and contains a growth factor called Spirulina Growth Factor. Another extract...
Guidelines for Maintenance of Aging Water Pipes
Break failure patterns are investigated by applying a new methodology based on Proportional hazards and Poisson-type models. Application on two water distribution systems of North-Eastern...
Tunneling Around Ft. McHenry
The world's largest underwater tunnel was built out of sight and sound of Ft. McHenry. The 4,000 ft tunnel needed to take I-95 from shore to shore had to be extended to 7,200...
Long Reinforced Concrete Columns
Papers selected by the Reinforced Concrete Research Council of ASCE. This collection contains 13 papers reporting the results of a series of studies,...
Reviewing for Potential Failure
The key to preventing structural failures is to examines them and develop systematic techniques for avoidance. One, called contingency analysis, starts with a what if process to decide...
Top Projects of 1986
In the 1986 ASCE competition to select the Outstanding Civil Engineering Achievement of the Year, 14 projects were nominated. This article describes the 10 non-winners. Technically the...
Geotechnical Construction Control Data Base Package
A data base can be defined as pieces or groups of data stored together in an orderly form such that access to all or any part of the data can be readily accomplished. A computerized data...
