Hydrograph Timebase
Based on the study of a large number of hydrographs, a graphic solution is presented whereby the length of the hydrograph timebase can be directly read from the proposed graphic solution...
The TENN-V Storm Hydrograph Simulation Model
TENN-V is a computerized, lumped, non-linear stormwater hydrograph simulation model for small unregulated watersheds. The applicability of TENN-V is best established in watersheds of less...
Sensitivity of CUHP-PC Computer Model
The Colorado Unit Hydrograph Procedure (CUHP) consists of effective rainfall reduction and hydrograph convolution processes. The primary assumption is an one-to-one response between rainfall...
Stochastic Streamflow Sequences for Reservoir Operation and Design
A stochastic streamflow model is adapted for risk methodology in the operation and design of reservoirs. The model is based upon the representation of the flood series as a Poisson counting...
Evaluation of Diffusion Models for Flood Routing
A study has been conducted to define the range of conditions with respect to hydrographs and channels encountered by SCS engineers in flood plain/flood control projects and to test two...
Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...
Summary of Floods and Droughts in the United States
This paper describes a current national analysis of streamflow data being conducted by the U.S. Geological Survey to identify and map, in a consistent State-by-State format, the frequency...
Modeling Side-Weir Diversions for Flood Control
Side-channel weirs can be used for diversion to reduce flood peaks. This study has developed a means for incorporating the effects of side weirs in HEC-1 and HEC-2 calculations through...
Partial Area, Variable Source, Rainfall Runoff Model Utilizing Digital Mapping
A partial area, variable source hydrologic rainfall/runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics, and several infiltration mechanisms....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Robotic Influence in the Conceptual Design of Mechanical Systems in Space and Vice Versa: A Survey
A survey is presented of the methods of constructing structural elements in space by the application of robotic devices. Two fundamentally different approaches to the solution of robotic...
Comparisons Between Space Facilities and Earth-Based Analogs
This presentation will focus on the design of planetary bases and space stations as based on comparative designs for facilities in analogous harsh and isolated environments here on Earth....
Highway Safety - Is the Job Finished?
A review of past measures undertaken to improve highway safety is given. The Highway Safety Acts have helped reduce the number of injuries and fatalities in spite of the increased number...
Historical Changes in Highway Safety: 1966 - 1987
During the past several decades, substantial changes have occurred in the national economy and culture. Corresponding changes have taken place in the highway transportation system. While...
Benefits of Highway Safety Improvement Programs
Even at the most conservative estimate of 2% annual growth in travel, the U.S. would experience almost 58,000 deaths in the year 2000 at a death rate of 2.5 per 100 million miles traveled....
Performance of an Artesian Glacial Drift Aquifer with Induced Recharge
The City of Kalamazoo, Michigan, has constructed induced recharge facilities at sites of several of its twenty-one well fields as part of a program for supplying potable water to Kalamazoo...
Jet Fuel from the Ground Up
The Port Authority of New York and New Jersey has implemented a multi-million dollar clean up effort to remove oil lenses beneath the bulk fuel farms it maintains at three New York area...
Drilled Piers in the Piedmont?Minimizing Contractor-Engineer-Owner Conflicts
Drilled piers are used extensively in the Piedmont Physiographic Region, deriving support primarily from end-bearing on hard rock. Cost extras and contractor-engineer-owner conflicts are...
Properties of Tin-Mined Land in Mangrove Forest, Thailand
Although mangrove forests occupy a very small area of Thailand, they contribute not only an ecosystem but also large tin ore deposits. Two provinces in the South, Ranong and Phangnga,...
Tidal Marshland Elevations in San Francisco Bay, California: Historic Accounts and Surveying Results (
The task of determining public agency jurisdiction in present and/or former tidal marshlands of San Francisco Bay is of importance in land use decisions and wetlands conservation. Jurisdiction...
