The Outstanding Civil Engineering Achievement of 1987 is the restoration of the Statue of Liberty in New York Harbor. The restoration work included many engineering tasks that by themselves...
The Applicability of Satellite Altimetry Data to Tidal Models
Different tidal regimes require different data assimilation schemes. In all cases, however, it is better to perform a separate tidal solution before assimilation. For proper assimilation...
Spatial Attenuation of Major Pennsylvania Storms
To utilize point estimates for more expansive areas, reduction factors are necessary to account for the attenuation of storm magnitude with increasing area. The spatial attenuation of...
Experiences of the U.S. Army Engineer District, Pittsburgh in Collecting Real-Time Water Control Data
As a result of an ever increasing need to optimize water use, 'Reservoir Regulation' has evolved into what is now known as 'Water Control Management'. In addition to the flood control...
ENDOW, An Expert System for Screening Environmental Features for Stream Alternations
This paper discusses development of an expert system for Environmental Design of Waterways Projects (ENDOW) by stream alteration specialists who were novices in artificial intelligence....
The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...
Denver Area Real Time System

Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...
Geographic Estimation of Runoff-Model Parameters
The U. S. Geological Survey is developing techniques to estimate and evaluate unit-hydrograph and loss-rate parameter values for rainfall-runoff models using Geographic Information System...
A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...
Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...
