Modified QUAL2E Modeling of a Stream Acutely Impacted by Photosynthesis and Respiration
The QUAL2E model was modified to account for time variable headwater conditions and the photosynthesis and respiration of attached aquatic plants. With these modifications, a stream that...
Extended Experience with a Short-Term Hydropower Scheduling Model in New England
The New England Power Exchange (NEPEX) is responsible for the central dispatch of power throughout New England. To assure the maximum benefits of power pooling, the electric facilities...
Hydropower, Water Quality and Waste Discharge
Development of multiple hydroelectric projects on large river systems can result in potential reductions in dissolved oxygen (DO) concentrations. Municipalities along the Ohio River basin...
Feasibility of Water Supply for City of Houston Subsidence Zones Five and Six
The purpose of this paper is to evaluate the feasibility of providing surface water to the Harris Galveston Coastal Subsidence District (HGCSD) Zones Five and Six (located in North Houston...
Reservoir Operating Rules for Maximum Hydropower Production
A procedure for testing the effectiveness of reservoir operating rules for real-time, multi-purpose reservoir operation is presented. Particularly, models that may be used to achieve maximum...
Prescriptive Model for Missouri River Reservoir-operation Analysis
The six main-stem reservoirs of the Missouri river system are operated by the Corps of Engineers for flood control, navigation, irrigation, power, water supply, water quality control,...
Energy Efficient Pump Station Operation with a Pump Switching Constraint
Pump operation scheduling has become a significant practical and research concern as utilities increase their computer usage. This paper presents an integer programming algorithm which...
Statistical Analysis of Wastewater Flow Reduction
Changes in urban water use patterns can significantly impact wastewater flow characteristics. With the increased emphasis on water conservation programs, understanding these impacts is...
Expert System for Operating A Treated Water Supply System
This paper presents a systematic approach to the development of an expert system to operate a treated water supply system for meeting daily water requirements. A treated water supply system...

Wastewater under Home Plate
A short, highly sloped piping system and peak flows at the start and end of the day were causing the wastewater treatment plant in Daly City, Calif., to frequently exceed its permit for...
Offshore Challenge
Standard design techniques weren't enough to create rigs for the Main Pass Mine, which, at 67 million long tons, is the largest offshore sulfur mine in U.S. history. The 18...
Boston's City within a City
The Massachusetts Water Resource Authority's 11-year effort to clean up Boston Harbor is in full swing. The nerve center of the project is Deer Island, a 210 acre site that...
Predicting Sediment Loads
Many reservoirs in the U.S. and internationally have experienced unforeseen storage loss when sediment loads exceed those originally predicted during the design stage. This often results...
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
