Abstract: This volume presents the methods used in collecting hydrologic geometry data in selected areas in Thailand. The selection, analysis, and classification of parameters significant to vehicle mobility are discussed. The photo-interpretation methods used in identifying hydrologic geometry features from aerial photographs (air photos) and the extrapolation of these identifications to areas not investigated on the ground are presented. The rationale for cartographic portrayal of these parameters is explained. Utilizing the collected field data, available air photos, and the Army Map Service series of topographic maps, hydrologic geometry factor maps were prepared covering the six selected study areas (Nakhon Sawan, Lop Buri, Chiang Mai, Chanthaburi, Pran Buri, and Khon Kaen). The maps are presented in Volume VIII of this series. It proved only partially possible to determine the existence and value of the chosen parameters from air photos since some of the individual factors are wholly or partially below the water surface. Nevertheless, photo interpretation plus extrapolation from measured sites made it possible to map the parametric values by class range with reasonable validity. Recommendations are made involving improvement in data-collection techniques.
