Abstract:

This study was conducted to assess the impact of terrain on horizontal construction in Army Facilities Components Systems four climatic zones. This included the identification of terrain conditions in selected countries within each zone and the evaluation of terrain effect variables used as input to the Engineer Horizontal Construction Effort Model EHCEM. This model estimates the number of engineer battalion-days to construct specific types of airfields. The present terrain input data were analyzed and the difficulty and volume indexes used in EHCEM were evaluated. The revised data were applied to the selected terrain condition countries. Terrain conditions were mapped in 20 countries within the four climatic zones by using available data and applying state-of-the-art mapping procedures. The terrain arrays were correlated with the volume and difficulty indexes. These data were used to identify the revisions required to improve the output of the EHCEM. The frequency and areal coverage of each unique terrain configuration array were determined and a statistical analysis was performed on terrain conditions that occur within each climatic zone.
