Seawater Intrusion in Salinas Valley, California
The rate of intrusion has been estimated to be about 19,000 acre-feet per year. If no action is taken to halt the intrusion, it is projected that in the year 2000 there will be as much...
Subsidence by Rising and Fluctuating Ground Water
Present studies by the U. S. Bureau of Reclamation in California indicate that under certain geologic conditions similar subsidence can also be caused by rising ground-water levels, which...
An Integrated Conceptual Expert System for Flood and Water Pollution Management
One particularly practical role for an expert system (ES) is as an interface between a complex computer model and an inexperienced user or novice. The software is applied to the USEPA...
Intelligent Central Database System for Synchronized Distributed Processing of Large Hydrologic Packages in Local Area Networks
The nodes of a local area network can be dedicated to the independent routines of a large hydrologic/hydraulic package. The server of the network can be dedicated to the control of the...
