This experiment were carried out to find the characteristic of textured surface bearing disk vary within the holes density and the depth itself. Holes were formed by ultrasonic machine (USM), with a diameter of 0.534 mm and a depth of about 2 – 4 mm and distributed on the contact surface with density between 1.37-2.23%. Nine kinds of textured specimen using typical trends of graph and photograph, which are taken using scanning electron microscope. The effect of holes density and its depth on friction coefficient was reported and discussed.

The purpose of this study was to develop techniques acquiring hydrologic parameters that affect runoff conditions from Landsat imagery. Runoff conditions in a study area were analyzed by .employing the U.S. Soil Conservation Service(SCS) Method. SCS runoff curve numbers(CN) were estimated by the computer analysis of Landsat imagery and digital terrain model(DTM) data. The SCS Method requires land use/cover and soil conditions of the area as input parameters. A land use/cover map of 5 hydrological classes was produced from the Landsat multi-spectral scanner imagery. Slope-gradient and contour maps were also made using the DTM topographic data. Inundation areas depending on reservoir levels were able to be mapped on the Landsat scene by combining the contour data.
