الملخص EN

This study was conducted by using soil map of LD7 project to interpret the distribution and shapes of map units by using the index of compaction as an index of map unit shape explanation.

Where there were wide and varied ranges of compaction index of map units, where the maximum value was 0.892 for MF9 map unit and the lower value was 0.010 for same map unit.

MF9 has wide range appearance of index of compaction after those indices were statistically analyzed by using cluster analysis to group the similar ranges together to ease using their values, so the unit MF9 was considered as key map unit that appears in the soils of LD7 project which may be used to expect another map units existence in area of that project and areas around which is considered an important step in soil survey works then classification and management of soils there.

78.57% of these indices where 0.526 or less that means they are low and reflects unit shape that is not simple and almost being elongated and branched ones.

While 21.42% of these samples were 0.526 or more which show high and medium indices with shapes simple or moderately simple and may have no branches.
