introductiondue to shortage of fresh water resources, the quality of impounded water behind the dams becomemore important than how it was previously as a source of fresh water resource. thermal regime anddissolved oxygen concentration are factors that affect the quality of water reservoirs.many lakes show vertical stratification of their water masses, at least for some extended timeperiods. the...

This paper, part 1 of a 2-part paper, gives a broad overview of data mining and describes several applications where it has been applied. Data mining is an emerging field that addresses the issue of converting large databases into knowledge. Data mining methods come from different technical fields such as signal processing, statistics, and artificial intelligence. Data mining employs methods fo...

Following an increased emphasis on watershed management by the U.S. Environmental Protection Agency (EPA) in the 1990s, the Kentucky Division of Water (KDOW) developed and implemented a watershed-management framework process for the state of Kentucky in 1997. The Kentucky Water Resources Research Institute (KWWRI) coordinated the first implementation of the framework process in the Kentucky Riv...

Several essential fish habitats lack the protections necessary to prevent degradation because of failure to integrate the scientific disciplines required to understand the causes of the degradation and failure to integrate the fragmented state and federal management authorities that each hold only a piece of the solution. Improved protection of essential habitat for demersal fishes requires muc...

There is a national trend for swine enterprises to increase in size due to cost efficiencies associated with economies of scale. This study was performed to evaluate the effect of farm size on manure application management for a survey o f 391 swine producers in Minnesota. There was a statistically significant effect of farm size on almost all of the variables evaluated. As farm size increased:...
