accordant landscape

Synonyms for the adjective accordant include consonant, agreeing, harmonious, corresponding, so it comes as no surprise that an accordant landscape contains two or more matching or congruent topographical features. Streams, folds, or summits, for instance, that occur at approximately the same elevation or have a similar orientation create accordant landscapes. Such uniform terrain can seem peaceful or monotonous, depending on your state of mind.
