This study introduces a cutting-edge approach to assess pedestrian risk in urban flood scenarios, applied to Cúcuta, Colombia, using a calibrated hydrological model and image recognition algorithms. It reveals a notable increase in risk with extended return periods, emphasizing the need for dynamic safety measures in urban planning. The findings set a precedent for applying this methodology in similar urban settings to improve pedestrian safety during flood events.

Short- and long-term legacies of carbon sequestration, and nutrient burial in floodplain wetlands of agricultural and forested catchments, Indiana, United States. Soil organic carbon (C) sequestration and nitrogen (N) and phosphorus (P) burial were measured in soils of two floodplain wetlands of the West Fork of the White River watershed (Indiana, USA) whose catchments differed in land use. These findings confirm previously published studies that show that P enrichment and accumulation in soils represent legacy effects of contemporary agricultural land use of the agricultural floodplain and historical tillage and plowing of the forested catchment.

The surface movement characteristics before and after the occurrence of landslides in the NE reservoir in the region scale were detected and interpreted by Sentinel-2 time series images. Experimental studies were conducted to investigate the geotechnical properties of the fine-grained soil. The slope stability was evaluated for a typical slope profile considering the rising water level using the extended Bishop's simplified method, which was implemented in the code STAB-UNSAT.

The flow and sediment measurement of the Three Gorges Project (TGP) is mainly introduced in this paper. It includes the general situation of the TGP, the distribution of the hydrological network, the measurement factors, the new measurement technology, and the sediment changes in the reservoir and downstream after the impoundment of the TGP.

The main sources of sediments are delineated, while corresponding loads are also quantified. After the analysis of those sediments in different periods, the relationship between economic development activities and sediment loads in Nyabugogo Stream were also determined.
