Technical Reports
Samples for water quality analyses and phycological studies were taken from the nine standard sampling locations on the Buffalo River nine times during the period from March 1976 through February 1977. The April-June 1976 samples represent nearly identical conditions throughout the spring period; therefore, emphasis was placed on taxonomic research. As the early January sample was considered sufficient~y reflective of stable winter conditions, the December and February periods were. used for detailed microscopic examination of the rich and diverse diatom flora that was found in the river this year. A total of 273 taxa of diatoms were identified from the …

Technical Reports
Intelligent development of groundwater resources is a process that requires a thorough understanding of the availability and movement of groundwater. In northern Arkansas knowledge of the deep aquifers is fairly limited, perhaps because economic factors and uncertain yields have discouraged exploitation. The development of these deeper aquifers to their fullest potential as reliable water sources depends on the delineation of high yield areas, a process that may be facilitated by linear trend analysis as outlined in this study. Satellite and photolineament maps of the 13 counties were prepared by use of LANDSAT images and Agricultural Stabilization and Conservation Service photo …
