Electronic Worksheet Applications in Hydrology and Hydraulics
Spreadsheet software packages are available for virtually all micro computers in use today. Although they are quite often thought of as business tools, their usefulness as engineering...
Applications of Point-Slope Reservoir Routing
The point-slope method of routing flood flow through a reservoir uses point functions rather than the time incremental functions of conventional methods. It can be used to give an accurate...
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...
Development of the Rio De La Plata Hydrographic Basin
The rivers and climate of the basin are described. Available and developed hydropower sites are presented. The international consequences of various water management schemes are discussed....
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...
Current Status of Urban Hydrology in Japan
After World War II the devastated Japanese landscape was ravaged repeatedly by heavy typhoons causing severe damages. Nevertheless, a hydrological data acquisition system was not adequately...
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...
Hydrographic Surveying Turns to Electronics
Traditional technique for measuring water depth is to use a lead-weighted line. The tag line, stretched along the water surface so soundings are made in orderly fashion, can be dangerous....
Recording River and Reservoir Water Depth
At the Kerr Reservoir on the Roanoke River in Virginia and North Carolina, reservoir bottom was surveyed before reservoir filling and twice thereafter, to determine rate of siltation....
A Hydrographic Surveyor's Most Memorable Day
Holbert Fear's most memorable day in a career as a hydrologist with the U.S. Geological Survey was in 1917, near Hanna, Wyoming. Fear was sent out to measure the flow of the North Platte...
Automated Hydrography for Channel Dredging
After studying both non-line of sight and microwave systems of over-water distance measurement, one of the latter was selected for checking dredged channel depth on the Delaware River....
A Critical Appraisal of Some Proposed Changes to the 1972 Water Pollution Control Act
The amendments that will ultimately be made to the 1972 Water Pollution Control Act (PL 92-500), now being discussed by Congress, will be influenced by a number of things happening in...
North Sea Oil-Water Mix
In the North Sea between Britian and Norway, giant structures are rising in one of the world's largest efforts to extract oil and gas offshore. An overview of the problems...
Water for the Southwest
Historical Survey and Guide to Historic Sites
In this document, a brief narrative history of the effects of the people who lived in the area (prehistoric Indians, the Spanish, and the Anglo-Americans) to secure and maintain water...
