“…During his studies of sediment stores in river catchments, Des Walling realized that the deposition of fine sediment could have important implications for nutrients, metals and other contaminants which are primarily or significantly transported in fluvial systems in sediment‐associated forms. In this Special Issue, Quine et al (2022) address the fate of organic carbon deposited in floodplain sediments. Investigating soil profiles to 0.8 m depth from the active channel belt and lowland floodplain under long‐term pasture in the catchment of the River Culm, South‐West England, they were able to determine using a wide range of field, laboratory and modelling techniques that sedimentation and carbon accumulation rates were 5–6 times greater in the active channel belt than in the adjacent floodplain.…”

Walling wrote his first papers about suspended sediment in Devon river catchments as a young hydrologist more than 50 years ago in the early 1970s. In those days, some very senior scientists told him he was wasting his time, because soil erosion in Britain was not a problem, and British rivers were not muddy! A half a century, and more than 500 publications (the majority of which are devoted to fine sediment in river catchments) later, Des is regarded as one of the world's leading hydrologists who have focused on erosion and sediment yields and catchment sediment budgets. His prolific, distinguished and frequently highly-cited research contributions have been recognized by important awards including the IAHS/UNESCO/ WMO International Hydrology Prize, the American Geophysical Union Hydrologic Sciences Award, the Norman Hudson Memorial Award of the World Association of Soil and Water Conservation, the Chien Ning International Prize of the World Association for Sedimentation and Erosion Research and the Victoria Medal of the Royal Geographical Society. Des has advocated eloquently and powerfully that sediment studies have an important role within the discipline of hydrology, not only because of the implications for environmental protection and sustainable development, but also because fine sediment represents a key pathway for material transport at all scales ranging from the individual farmer's field to the global earth system. In order to underpin his work, Des established an intensive programme of field investigations through a network of long-term measuring sites in the local Exe basin, which operated for over 30 years. He also developed complementary high quality laboratory facilities in the Geography Department at the University of Exeter for studying sediment properties, including one of the best-equipped gamma spectrometry laboratories in the world. However, he was also keen to extend the canvas on which he worked beyond the local to the national and the international. Such activity has seen him conducting soil loss studies across several areas of Britain and investigating the delivery of sediment through larger river systems including the River Severn and the Yorkshire Ouse. He has also carried out much work overseas in North, East and Southern Africa,
