Here are a series of simple QGIS style files that I use to style basic topographic maps:
Contours (vector) - 5m_contours_scale.qml - 5m contours with 50m index contours. More detailed contours are only shown as you zoom in, keeping the map less cluttered.
Streams (vector) - basic_watercourse.qml - a very basic styling for vector watercourses
Slopes (raster) - slope_cliffline.qml - gradient colouring of slopes from 40 to 90 degrees to depict clifflines
Other styles
Slopes (categorised raster) - slope_cliffline_category.qml - if you categorise your slope raster as described in Slopes then you will need this variation of the slope style
