DEPTH TO GROUND-WATER TABLE BY REMOTE SENSING

THE POTENTIAL OF INFRARED IMAGERY, AS A REMOTE SENSING TECHNIQUE, IN DETECTING AND SURVEYING DEPTH TO GROUND- WATER TABLE IS INVESTIGATED. THE VARIATION OF SOIL RADIANT ENERGY FROM TWO TYPES OF SOILS IN THE 8 MU - 14 MU INFRARED SPECTRAL BAND AS AFFECTED BY DEPTH TO GROUND-WATER TABLE WAS STUDIED IN A SPECIALLLY DESIGNED APPARATUS. RESULTS OF EXPERIMENTS INDICATED THAT: DIFFERENCES IN DEPTH TO GROUND-WATER TABLE, WITHIN THE RANGE USED IN EXPERIMENT 0 FT TO 4 FT LEVEL, IN BOTH TYPES OF SOILS USED, WAS DETECTABLE BY GROUND SURFACE RADIANCE MEASUREMENTS IN THE 8 MU - 14 MU WAVE BAND; DURING THE PERIOD OF INVESTIGATION (SUMMER), RADIANT INTENSITY WAS MAXIMUM FORM 2 P. M. - 4 P. M.; MAXIMUM RADIANT INTENSITY DIFFERENCE RESULTING FROM VARIATIONS TO DEPTH OF WATER TABLE ALSO OCCURRED DURING THIS PERIOD WERE SIGNIFICANT, SUGGESTING EXCELLENT POTENTIAL APPLICATIONS OF MOST OF THE HIGHCLASS UNCLASSIFIED COMMERCIAL IMAGING SYSTEMS IN DETECTING AND SURVEYING DEPTH TO GROUND-WATER TABLE AND SOIL MOISTURE VARIATIONS. /AUTHOR/
