In 1994, the Federal-State Cooperative Program served as the sole source of funding for the operation of more than 4,200 continuous streamflow stations and partially funded an additional 650 continuous streamflow stations. Number of cooperators in the 1994 Federal-State Cooperative Program. Hydrologic data can be accessed through USGS offices in every State and will soon be available over the Internet. The benefits of the program are demonstrated by the extent to which other agencies apply the information produced. Many Cooperative Program activities provide information necessary for making water management decisions.
Several examples follow.
This study represents one of the first attempts at modeling contaminant transport in fractured rock, and will serve to advance the understanding of fractured-rock hydrogeology. This knowledge will be used to solve contamination problems in other fractured-rock environments. The numerous equations that have been developed to predict scour produce a wide range of estimates for the same set of conditions. However, field data to test the validity of these equations are sparse. The USGS, in cooperation with State Highway Departments in Delaware, Maryland, and Virginia, is developing techniques for measuring scour continuously at bridge piers to improve the predictive equations.
