This volume contains sixteen papers organized by their focus on measurement, theory, or application. Six papers present ongoing research from Spain, particularly in Catalonia, where high winter precipitation leads to significant seasonal contrasts. Avila & Roda explore chemical denudation in the same area as SALA's study on mechanical erosion, while Sevink examines the influence of organic soil horizons on these processes. The next four papers by Brown, Burt, Rogner, and Mietton report findings from England, California, Israel, and Burkina Faso, respectively. Brown highlights magnetic susceptibility studies in Mediterranean environments; Rogner discusses cavernous weathering in the Negev; Burt addresses nitrate leaching seasonality in southwest England; and Mietton tackles temperature measurement challenges in Burkina Faso's hot, dry climate. The final two papers by La Roca & Calvo Cases focus on measurement methods in Valencia's marls, emphasizing the impact of extreme events on processes and morphological development. Poesen & Torri investigate how cup size affects splash transport and detachment, while I Meson & Verstraten relate rill initiation to soil properties. The last three application-focused papers address soil erosion: Lewis uses the USLE in Rwanda to assess groundcover effects; Zanchi studies seasonal soil erodibility variations in Central Italy; and Goczan & Kertesz present findings from Hungary.
