This document provides recommendations for scales to use when creating geological and geotechnical maps for different stages of river valley projects. It recommends scales of 1:50,000 for reconnaissance mapping, 1:15,000 for surface mapping and preliminary subsurface exploration in the preliminary investigation stage, and 1:5,000 with 2m contour intervals for detailed mapping of concrete dam sites in the preliminary stage. Scales are proposed to meet the needs of planning, design, and construction at each p
