What is the meaning of "wash height" (topography) in something related to habitat description?
Hi! I'm making a investigation from habitat description. The autor describe a variable by" visual estimation of
wash height", but i don't understand what he means with "wash""Our topographic index was determined by visual estimation of wash height along two 250-m transects radiating from the burrow and oriented perpendicular to local wash terrain. All wash heights were
summed to produce the topographic index."
