Prepared in cooperation with the Missouri Department of Natural Resources Abstract: Planning waste-disposal facilities and impoundments is complicated by karst carbonate terrane in the Ozarks. Thermal imagery( 8-13 micrometer wavelength) and color infrared photography aid in identifying losing streams, sinkholes and hydrologic conditions encouraging collapse. Imagery and photography were acquired in Greene and Reynold Counties,Mo. in March 1972 and June1973. Differences in thermal levels correlating with losing and gaining reaches of Logan Creek valley, Reynolds County, were not visually apparent in predawn March imagery but statistical analysis of predawn magnetic- tape data indicated greater variance in emitted energy from the losing reach than from the gaining reach. In June, the gaining reach of Logan Creek was darker (cooler) on thermal imagery than the lighter (warmer) losing reach at postsunset and predawn. Overflights between May and June 1973, using a radiometer strengthened the visual interpretation of the imagery. Spring and autumn are poor times to collect thermal data for this purpose midday in late summer may be a very good time.
