Effect of roughness on fluid flow and solute transport in a single fracture: A review of recent developments, current trends, and future research

Difficulties encountered in describing fracture flow using classical fluid flow equations has led to extensive studies of the roughness effect on fracture flow over the past 70 years. Despite the significant progress made thus far, understanding the impact of roughness on fracture flow remains a complex challenge, as suggested by the discrepancies found among theoretical, numerical, and experimental observations. In this review paper, we discuss...
