Observations of Water Movement in a Block of Fractured Welded Tuff
Climate Warming and Great Lakes Management
A decision-analysis approach to determining the relevance of information on climate change for near-term Great Lakes management decisions is outlined. Simplified applications to decisions...
Interactive Models for the Regulation of Lake Ontario
Extensive studies are underway to improve the regulation of Lake Ontario. These studies not only involve the inclusion of factors and interest groups not previously considered, but also...
Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...
Accounting for Antecedent Conditions in Seawater Intrusion Modeling—Applications for the San Francisco Bay-Delta
A new method for predicting salinity variation with outflow is developed for the western Sacramento-San Joaquin Delta in northern California. A simple routing equation is used to calculate...
Real Time Forecasting at a Major Flood Control Project
Using data from a network of real time rain and stream gages, Alabama Power computes inflows in a deterministic streamflow model and adjusts outflows hourly to achieve optimum flood control...
Site Specific Hydrological Model for Permaculture Application
This paper presents results of a study conducted on a small pond and watershed in Waterbury, Connecticut. The Soil Conservation Service method presented in Technical Release #55 (TR 55),...
Equipment and Instrumentation for CSO Control
A Generalization of Steady-State Flow Calculation for Design and Control of Water Distribution Networks
The Influence of Water Tables on Herbicide Losses
Atrazine and metolachlor were applied preemergent on April 22, 1987, to silage corn on high watertable fields which were either subsurface drained (104 mm drain tubes 1 m deep) or surface...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...

Load-Detention Efficiencies in a Dry-Pond Basin
Inflow and outflow to a dry-pond detention basin in Topeka, Kansas, were monitored for 19 storms during a 14-month period. Samples of runoff were collected automatically at two inflow...
Coastal Groundwater Outflow: Solution to a Dynamic Problem
The pattern of fresh groundwater outflow at the coastal margin of a phreatic aquifer can be approximated by a quasi-transient analytical model. The suggested procedure includes transformation...
Effects of Reservoir Regulation on Channel Morphology
A case study is presented in which such a multidisciplinary approach was used to evaluate the impacts of regulated outflows from the recently completed Warm Springs Dam Project (Sonoma...
A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...
Estimating Peak Flow Reduction in Small Reservoirs
A microcomputer program is used to provide a simple and rapid estimate of the peak outflow from such reservoirs. Peak flow values, determined by flood frequency analysis or regional flood...
Microcomputer Control for a Small Hydroelectric Peaking Plant
Peaking plants pose a special problem for control. The new facilities are generally a very small part of a large system. Determination of the parameters necessary to run the plant to best...
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...
Financial Management for an Engineering Firm
The CEO usually delegates the responsibility for financial management to the Chief Financial Officer who, in turn, selects from an array of management techniques to control costs, revenues,...
