Influence of Soil and Land-Use/Land-Cover Data Quality on SWAT Parameter Transferability in Small Subtropical Agricultural Watersheds Elzon C. Rippel, Daniel G. A. Piccilli, Latif Kalin, Rutinéia Tassi, Cristiano Gabriel Persch, et al. Hydrological Processes, 2026 Regionalisation of hydrological model parameters is a cornerstone of Prediction in Ungauged Basins (PUB), yet the level of input‐data detail required for reliable parameter transfer remains unclear, particularly in intensively managed agricultural landscapes with intra‐annual land‐use/land‐cover (LULC) dynamics associated with multi‐cropping systems. While recent studies have primarily focused on refining transfer techniques—such as proximity, similarity, regression, fuzzy clustering, or machine learning—the role of watershed descriptor quality has rarely been explored. Here, we evaluated how soil and LULC data quality control the transferability of SWAT parameters through a factorial proxy‐basin experiment in two small subtropical agricultural watersheds in southern Brazil (WS80: 0.80 km 2 , WS140: 1.39 km 2 ). Four scenarios crossed two levels of soil data quality (global HWSD at 1:5000000 vs. locally sampled at approximately 1:50000) with two levels of LULC representation (static default management vs. dynamic, EVI2‐derived crop–livestock rotations). Calibration performance improved in WS80 from NSE = 0.16 under coarse soil and static LULC to NSE = 0.75 when dynamic LULC was included. Under direct parameter transfer, the combined fine‐soil and dynamic‐LULC scenario achieved satisfactory NSE in both target directions (0.56 and 0.55), compared with NSE = 0.06–0.25 under the baseline global‐soil/static‐LULC scenario. Post‐transfer PBIAS ranged from −67.2% to +48.8% across coarse‐soil scenarios, whereas the fine‐soil/dynamic‐LULC scenario reduced PBIAS to −39.9% and + 28.7%. Our findings show that, in small managed agricultural watersheds, improving the physical realism of watershed descriptors can substantially increase SWAT parameter transferability, and that both soil and dynamic LULC upgrades are needed to achieve satisfactory model performance with transferred parameters.
The exceptional hydrological disaster of April-May 2024 in southern Brazil Walter Collischonn, Fernando Mainardi Fan, Iporã Possantti, Fernando Dornelles, Rodrigo Paiva, et al. Revista Brasileira De Recursos Hidricos, 2025 We present an overview of the unprecedent hydrological event that occurred in Rio Grande do Sul state in late April and early May 2024, causing floods and landslides in a scale that was not seen before in Brazil. The rainfall that caused the disaster is incomparable to any recent event in Brazil at large spatial and temporal scale. The intense and long-lasting precipitation led to record floods from small rivers with drainage areas below 1000 km2 to the Patos Lagoon, which drains more than 180,000 km2. The rainfall also led to landslides that rank first in Brazil in terms of spatial scale and number of occurrences. Mountain rivers experienced flash floods with extreme water levels, while in the lowlands the large rivers and the Patos Lagoon experienced long duration flooding, with stage remaining high for about 30 days. The flood event is probably ranked first in terms of displaced people and damage to property and infrastructure in Brazil. Almost 200 fatalities occurred due to the disaster and protection structure failures. The April-May hydrological event show a glimpse of what can be expected along the coming decades due to climate change in a region that covers South Brazil, and parts of the neighboring countries.
