Expert System for Wastewater Collection System Infiltration and Inflow Mitigation

An Approach for Incorporating Inflows Uncertainty in Management Models
Inflow uncertainty is probably the most difficult issue for optimal management of conjunctive use water resources systems. In many instances, the effect of future inflows and their uncertainty...

Water Supply Operations During Drought
During years when water supply may not be adequate to cover water demands, water supply decision maker or managers need to decide how to spread projected shortages through the anticipated...

In-Channel Sediment Basins: An Alternative to Dam-Style Debris Basins

Stochastic Optimization for Long Term Operation of Multiple Reservoirs: A New Approach
The study emphasis of optimal scheduling of reservoir system operations has shifted to stochastic mathematical programming since future reservoir inflows are uncertain and recent advances...

1991 Update on Sanitary Sewer Rehabilitation Metropolitan Chicago
The Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) owns intercepting sewers and seven water reclamation plants, but 125 local communities own the local sewers which...

Hydraulic Analysis of the Impacts of I/I on System Capacity
The USEPA Stormwater Management Model was used to evaluate the impact of infiltration and inflow on the separate sewer facilities of one of the largest sewage treatment districts in the...

Navy Targets Effective Infiltration/Inflow Elimination
The Naval Facilities Engineering Command (NAVFAC), Chesapeake Division, retained the services of RJN Environmental Associates, Inc. to perform a Sanitary Sewer Evaluation Survey (SSES)....

Brule Hydroelectric Project Inflow Design Flood Study
In 1987, Wisconsin Electric Power Company (WE) was directed by FERC to provide additional spillway capacity at it's 63-foot (19 m) high Brule Dam. Original spillway capacity...

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...

Analysis of Thermal Scanning Imagery to Investigate Point Inflows Into Surface Water Bodies
Using a modified technique of thermal infrared remote sensing, physical sampling, and data analysis (graphical and geostatistical) locating a small inflow to a lake was possible. Thermal...

Optimal Real-Time Operation of Te-Chi Reservoir
An optimization model for the 10-day operation of Te-Chi Reservoir in central Taiwan is developed. The inflow to the reservoir is forecasted by an ARX model with a Kalman Filter updating...

Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....

Recent Progress on Hydrodynamic Modeling of San Francisco Bay, California
A hydrodynamic modeling study of the effects of freshwater inflow on circulation and mixing in San Francisco Bay has been underway since 1985. This paper describes the multidimensional...

On the Problem of Sediment Deposition in Large Reservoirs
Sediment deposition and its accumulation in a large reservoir depends on the inflow and reservoir storage content, respectively. This fact is used to model the cumulative deposition of...

Dense Inflows Into Narrow Reservoirs

Optimization of Freshwater Inflow to Estuaries
This paper presents a methodology that can be used for determining the optimal freshwater inflows into bays and estuaries for the purpose of balancing freshwater demands with the harvest...

Estimating Lake Inflows for Storage by Linear Programming
The Lower Colorado River Authority (LCRA) recently completed a Water Management Plan for the lower Colorado River Basin in Texas. In developing the Plan, a daily river flow routing procedure,...
