Page 766 - These reservoirs have a combined storage capacity of 317, 700 acre-feet (one acre-foot is equal to the quantity of water required to cover one acre to a. depth of one foot and is equivalent to 43, 560 cubic feet or 325,851 gallons).
Page 649 - The dominant limnological feature of the Great Plains today takes the form of reservoirs constructed by the US Army Corps of Engineers and the US Bureau of Reclamation. The primary influence on the reservoir ecosystem is the suspended material and chemicals carried in by streams and rivers. The authors are studying ERTS images of Kansas reservoirs to determine the feasibility of monitoring these water quality indicators by satellite. The reservoirs throughout the state...

Page 473 - ERTS-1 multispectral data by automatic pattern recognition procedures is applicable toward grappling with current and future resource stresses by providing a means for refining existing geologic maps. The procedures used in the current analysis already yield encouraging results toward the eventual machine recognition of extensive surface lithologie and topographic patterns. Automatic mapping of a series of hogbacks, strike valleys, and alluvial surfaces along the northwest flank of the San Juan Basin...

Page 649 - ERTS overpass and analyzed for concentrations of inorganic suspended and dissolved solids, organic suspended and dissolved solids, chlorophyll, potassium, phosphate, and nitrate ions. In addition, secchi disc and temperature measurements are taken at each sampling station. The two reservoirs are distinct in terms of adjacent outcropping rocks and land use.

Page 200 - In each case, an attempt is made to ensure that the types of information compiled (eg, maps, tabular data, crop acreages, etc.) conform to actual requirements or desires as expressed by those persons currently involved in resource evaluations and planning in the test site. In the area of agricultural land stratification...

Page 83 - The pinyon/ juniper-northern desert shrub ecotone is being evaluated by identifying individual ecotones of varying length. The success of accurately defining these ecotones on ERTS-1 imagery has been determined (Table 3) . Color infrared has proven superior and was not as susceptable to error caused by the appearance of landforms as was the black and white imagery. Small amounts of infrared reflectance caused by the presence of pinyon/ juniper is detectable with the Color IR imagery, thus preventing...
