Flood Travel Time
The effects of infiltration on the flood travel time are investigated. In flood prediction, the physical domain for flood cumulation is expressed by the period of time for water to travel...
Aeration is the Solution for Sluice Cavitation Damage at Libby Dam, Montana
Cavitation has severely damaged two of the high-head flood control sluices. The damaged areas were immediately patched; however, these patches were not considered a solution to the problem....
Controlling River Ice to Alleviate Ice Jam Flooding
Many communities affected by ice jam flooding have accepted the event as unpreventable. Others have approached their problem as one of open channel flow and implemented standard projects...
Salmon River Ice Jams
The ice conditions on the river during the freeze-up period and the simple analytical model used to predict the advance of the ice cover leading edge are documented. Ice cover thicknesses...
Forecasting and Warning for Mt. St. Helens Streams
The eruption of Mt. St. Helens in southern Washington on May 18, 1980, created great devastation both by the blast itself and by mudflows generated by melting snow and ice. Several hydrologic...
Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...
Alluvial Fans: Novel Flood Challenge
After disastrous floods hit Cabazon, Calif., engineers faced the challenge of balancing concerns about protecting property and life (by limiting or prohibiting construction) against the...
Flood Routing on a Small Computer
A BASIC program is developed to route flood discharge through a system of river channels and reservoirs. The brevity of this program and the use of an overlaid computational matrix make...
Earth Reinforced Dams: First in U.S.
Earth reinforcement has in recent years been applied in the restoration and construction of dams. Earth reinforcement has been used to raise dam heights, replace traditional earth embankments...
Prgoress Since 1979 in India
Since India is a developing nation urban flood control benefits which are 'negative goods' have a low priority. Recently there is an increased awareness in India...
Urban Creekside Design Features Parallel Streets
Waterflow in cities�natural streams and rivers surrounded by wildlife, or concrete channels�must be controlled to prevent devastating flooding. Proper landuse restraints and creative designs...
L.A.'s New Maintenance Management System: Key to Survival in an Era of Tight Budgets
Even in the wake of budget-cutting Proposition 13, the Los Angeles County Flood Control District was able to cope with their maintenance needs. Their secret was a major overhaul in their...
Hydrologic Applications for Electronic Spreadsheets
Electronic spreadsheets have many potential applications to civil engineering. They are ideal for the derivation of unit hydrographs and the construction of design storm hydrographs. They...
Flood Routing Program
This is the fourth article in Civil Engineering�ASCE's computer series. A BASIC language program is presented for routing floods through storage reservoirs or detention basins...
Flood Consideration for Sanitary Structures
An approach is presented to determine the design basis flood for Sanitary Structures and means to protect them. Flood and flood frequency are defined. Principal classes of flood are evaluated...
Space Shuttle
In modifying the decade-old Apollo man-to-the-moon launch facilities at Cape Kennedy, FL, for the forthcoming Space Shuttle mission NASA and contractors made two major innovations: To...
Don't Always Put Dam in Narrowest Part of Valley
Hydraulic factors must be taken into account in dam planning and design, because the best structural design is not always the most economical. When the potential for downstream flood damage...
Urban Stormwater Management in Coastal Areas
The proceedings of the National Symposium on Urban Stormwater Management in Coastal Areas brings together the disciplines of urban stormwater management and ocean and coastal engineering....
Gabions: Economical, Environmentally Compatible Erosion Control
Not well known in this country, gabions have been in use for about 75 years in Europe. Gabions are wire baskets, filled with rock and wired together to form an erosion control or bank...
Flood Studies Led to National Flood Insurance
Federal responsibility for flood insurance was decreed by Congress in 1956, after it realized that the private insurance could not alone bear the risk. Flood-plain management, a prerequisite...
