      <title>TERRAIN EVALUATION IN WEST MALAYSIA, PART 2--LAND SYSTEMS OF SOUTH WEST MALAYSIA</title>
      <link>https://trid.trb.org/View/71327</link>
      <description><![CDATA[This report describes land system mapping applied in the south of West Malaysia.  Together with part 1, Terrain Classification and Survey Methods, it demonstrates the use of terrain classification and evaluation in a humid tropical environment.  The purpose of terrain evaluation is to assist project managers and field surveyors to locate the most suitable areas for a project and to plan a field sampling programme appropriate to the variability of the soils.  Its particular advantages are speed of mapping, application in several different disciplines, and storage of information in an accessible and re-usable form.  The terrain is classified into small and large scale mapping units (land systems and land facets).  A description of the topography, soil profile and water relations is given for each land unit, with additional information on the engineering properties of the soils.  Land systems are identified on a 1:250,000 scale map, grouped into major topographic and geological units. Differences in the engineering properties of the soils were found to be significant only at this level, owing to the intense nature of the weathering.  The map also forms the key to the land facet associtions, to provide a complete breakdown of the topography and soils for site investigations.  /Author/]]></description>

      <title>TERRAIN EVALUATION IN WEST MALAYSIA-PART I-TERRAIN CLASSIFICATION AND SURVEY METHODS</title>
      <link>https://trid.trb.org/View/117792</link>
      <description><![CDATA[THIS REPORT IS THE FIRST OF THREE ON THE APPLICATION OF TERRAIN EVALUATION TO HIGHWAY ENGINEERING IN THE HUMID TROPICS. THE STUDY AREA IS THE SOUTHWEST CORNER OF THE MALAY PENINSULA, AND THIS REPORT DESCRIBES THE PROCEDURE FOR CLASSIFYING ITS TERRAINS, USING AERIAL PHOTOGRAPHS. THE OXFORD-MEXE SYSTEM OF LAND CLASSIFICATION IS EXPLAINED, AND BRIEFLY COMPARED WITH THE WORK OF OTHER ORGANIZATIONS. THE PROCEDURE FOR CLASSIFYING THE TERRAINS OF SOUTH WEST MALAYSIA IS THEN DESCRIBED. THE DENSE VEGETATION SEVERLY HINDERED AIR PHOTO INTERPRETATION, BUT IN THE LOWLANDS, WHERE MOST OF THE TERRAIN VARIATIONS OCCURRED, THERE WERE ENOUGH GAPS IN THE TREE COVER TO SEE THE LAND SURFACE. IT IS CONCLUDED THAT NO MODIFICATIONS ARE REQUIRED TO THE ESTABLISHED SYSTEM OF LAND CLASSIFICATION, ALTHOUGH THE COMPLEXITY OF THE TERRAIN (DUE TO THE INTENSE CLIMATIC WEATHERING) HAS DEMANDED A LARGER MAPPING SCALE THAN HITHERTO. UNDER COMPLETE FOREST COVER IT IS NOT POSSIBLE TO CARRY OUT A FULLY DETAILED LAND CLASSIFICATION NEEDED FOR SITE INESTIGATION BECAUSE THE TREES OBSCURE THE DETAILS OF THE LAND SURFACE. BUT UNDER THESE CONDITIONS A MORE GENERAL CLASSIFICATION CAN BE MADE WHICH IS USEFUL IN THE PRELIMINARY STAGES OF ENGINEERING SURVEYS. TWO APPENDICES GIVE AN OUTLINE OF THE CLIMATE, GEOLOGY AND STRUCTURAL HISTORY OF THE MALAY PENINSULA, AND A DESCRIPTION OF THE EFFECTS OF WEATHERING UPON THE ROCKS. /AUTHOR/]]></description>
