To specify highly lobate plan-view clinoform geometry, characteristic of a fluvial-dominated delta ([[:File:BLTN13190fig3.jpg|Figure 3C]]), the user specifies a larger value for the clinoform in the depositional dip direction, BLTN13190eq47, than for the clinoform in the strike direction, BLTN13190eq48. For a highly elongate or near-linear plan-view clinoform geometry, characteristic of a wave-dominated shoreline ([[:File:BLTN13190fig3.jpg|Figure 3A, B]]), the user specifies a much larger value for the clinoform in the depositional strike direction, BLTN13190eq49, than for the clinoform in the dip direction, BLTN13190eq50. Data describing clinoform extent in depositional dip and strike directions can be extracted from published data on the dimensions of ancient shorelines or by analysis of their modern counterparts (e.g., tables 1, 2 in Howell et al., 2008a).
