The author has identified the following significant results. False-color composites made from ratioed and stretched transparencies, generated from CCT's of ERTS-1, have enhanced hydrologic and morphologic differences within the playa surficial sediments. A composite of ratios 4/6, 5/7,15/61 and 4/7 using blue, red, yellow, and green, respectively, was useful in separating wet, water, and dry areas in the salt crust and for delineating smooth and rough salt where relief was less than 20 cm

c. Problems encountered during this reporting period include:
1. The single remaining recorder aboard ERTS-1 was shut down
due to malfunction, on 29 March 1973. Consequently, there
will be no further images of Iran until a ground receiving
station is built in that country.
The principal part of my ERTS-I experiment consisted of an
examination of the Iranian Playas during the wet season (May),
when the playas are flooded or saturated resulting in dynamic
changes in the strength of playa soils and their utility for
roads or airfields. I had intended to establish ground truth
in Iran during May, but the absence of contemporaneous
ERTS-1 images no longer justifies such fieldwork.
I will attempt to utilize some of the January-February ERTS-I
coverage of some playas which are saturated by winter rainfall,
and compare their conditions with the summer, dry conditions
of these same playas.
d. Accomplishments during the reporting period include:
1. Nine-inch ERTS-I film positives (cycle 3) were used in the
preparation of black and white enlargements at scales of
1:500,000 and 1:250,000. Although the smaller scale print
was more attractive; the larger scale was just as faithful
in detail and permitted easier delineation of map areas
within the playas.
2. Nine-inch ERTS-I film positives (cycle 3) were used in the
preparation of false color diazo prints. Many film color
and exposure times were used in order to determine the best
combination for examining the boundaries around areas of
water, salt, clay and shoreline.

d. Accomplishments during the reporting period include:
1. A map is in preparation that will illustrate the progressive
increase and then decrease in the water-borne sediment load
within a playa lake through the seasons. A three-stage masking
technique being used is as follows: (1) A negative is prepared
from the ERTS-I, 9.5-inch positive of band 5 from each scene;
(2) a sandwich is made of the scene's negative band 5 and
positive band 4; (3) a positive is made from this sandwich,
and then a false-color composite is made from the several
sequential positives, each representing a place in the silting-
up of the playa lake.

generated from CCTs of ERTS-I, have enhanced hydrologic and

d. Accomplishments during the reporting period include:
1. Examinations of false color diazo prints of Qom Playa, 100 km
southeast of Tehran, indicate that in 1972 there was a dramatic
flooding of the western part of the playa during the first 3
weeks in December. Some additional flooding occurred in early
January 1973, but the maximum inundation was attained by mid-
May 1973. At that time, the northwestern quarter of the playa
was covered with water, and the remaining salt crust was locally
flooded.
2. By accentuating Band 5 (silt) and muting Band 7 (water), the
dense silt plumes that are conspicuous in Qom Playa in December
may be compared with the very thin plumes that are present in
May. At the latter time, most of the water inflow is from the
toes of alluvial fans rather than from the major streams.

The utilization of ERTS-1 generated photographs in the evaluation of the Iranian Playas as potential locations for economic and engineering development

The author has identified the following significant results. Seasonal monitoring of hydrologic conditions at three playa lakes provides a basis for constructing an annual water inventory for these lakes. Although the extreme variation in the extent of playa lakes must be considered, the principal periods of their fluctuations are generally constant. Playa lakes provide an important water source for arid region needs, and their water can be diverted and stored for use during the long, hot, and dry summer. At their 1973 maxima, approximately 400 million cu m and 794 million cu m of water were available at the lakes at Qom and Neriz playas, respectively. These lakes adjoin areas of moderately dense population that have severe annual water deficits. A preliminary road alignment across the Great Kavir in north-central Iran has been prepared from an analysis of ERTS-1 images of that area from September 2, 1972, through May 12, 1973, a total of 6 scenes. An all-weather road constructed along this alignment could reduce the distance between points north and south of the Great Kavir by as much as 700 km
