Innovative reregulation weirs
Article Abstract:
Timber-crib and labyrinth weirs can effectively correct too slow or too fast water flow from a hydroelectric dam, thus avoiding disruption of marine life downstream. This the Tennessee Valley Authority proved by testing its own designs for a timber-crib weir in the Clinch River in 1984 and a labyrinth weir in the South Fork Holston River in 1991. Labyrinth weirs, though more costly than timber-crib weirs, promote better water aeration and their surface construction prevents their being used as fishing piers. Boats, however, cannot pass over labyrinth weirs as they can over timber-crib weirs.

Project object
Article Abstract:
The Power and Reservoir System Model (PRSYM) is an object-oriented software package for optimizing hydroenergy production in river, reservoir, and hydropower systems. PRYSM's data include basin topology, methods for modeling various characteristics of water systems, and operating policies. A model can be tailored to assess specific systems by constructing user-specific object libraries containing solution methods inherent to the system being modeled.

Re-engineering the Mississippi
Article Abstract:
The Mississippi River Delta is situated in coastal Louisiana and is a major commerce center playing an important role in the U.S. economy. The problem it faces is that it has lost almost 9,00,000 acres of wetland and is heading for a further loss unless it is reengineered.
