South Branch Rockaway Flood Water Study
The paper reports on a study to analyze in detail various methods of storm water management. The technical studies were carried out in an actual watershed setting to arrive at a recommended...
Application of Geographic Information System for Hydrologic Investigation
The Illinois Department of Energy and Natural Resources is developing a geographic information system (GIS) under the federally funded Lands Unsuitable for Mining Program (LUMP). This...
Using Remotely Sensed Data to Estimate Runoff
The paper reports on a study to conduct numerical experiments to simulate runoff from watersheds by using remotely sensed data and hydrologic models. Data from the Sugar Creek Watershed...
Control of Select Priority Pollutants in Stormwater
A simulation program to generate the runoff quantity and quality for each storm event over a 5 year period was written. Chemical loading rate data from highways was used. Runoff was considered...
State Space Approach to Flood Stage Estimation
A flood routing and stage prediction model is developed using the techniques of State Space and Kalman filtering. The governing equation is the physically based hydrologic method of flood...
Computer-Based Predictions of Atchafalaya Bay Sedimentation
The Atchafalaya River, a distributary of the Mississippi River, discharges into Atchafalaya Bay through the Lower Atchafalaya River and Wax Lake Outlet. The bay delta has grown rapidly...
Numerical Modeling of Fine Sediment Physical Processes
Fine sediment in channels, rivers, estuaries, and coastal waters undergo several physical processes including flocculation, floc disruption, deposition, bed consolidation, and resuspension....
Prediction of Shoaling in Estuarial Channels: A Microcomputer Application
Shoaling rates at three predominant areas of sedimentation in the Hooghly River estuary, India, have been predicted using a sediment transport model run on an IBM compatible microcomputer....
The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...
Energy Dissipation in Tidal Waterways
Energy dissipation in tidal waterways is estimated analytically by a harmonic method. Calibration of harmonic parameters is done through numerical simulation. Relations between tidal energy...
Friction in Hurricane Induced Surges
Bed shear stresses induced by the flowing water are expressed by means of a friction factor for which formulas are developed for: ocean bottom, mangrove fringes and areas, forested areas...
