Geomorphological indicators for environmental impact assessment: consumable and non-consumable geomorphological resources

Abstract A methodological approach is proposed for the incorporation of geomorphological features into environmental impact assessments. A series of quantitative indicators and indices are proposed, so that impacts on both consumable and non-consumable geomorphological resources can be objectively determined. Impact can thus be expressed by means of magnitudes with specific dimensions, or at least as fractions of a maximum theoretical value. Procedures for the integration of individual indices into general impact assessments are also proposed.
