THE HYDROLOGIC CONTROL ON SHALLOW LANDSLIDE TRIGGERING: EMPIRICAL AND MONTE CARLO PYSICALLY-BASED APPROACHES
… In particular, an integrated stochastic rainfall and deterministic landslide simulator has been developed for the purpose. The simulator is composed by the following components: (i) a seasonal Neyman-Scott Rectangular Pulses (NRSP) model to generate synthetic hourly point rainfall data; …

Flood risk modeling and impact assessment using google earth engine in Mpumalanga province, South Africa
… was conducted (February 2023 flood) using threshold-based change detection methods applied to Sentinel-1 Synthetic Aperture Radar (SAR) data to map the spatial extent of inundation. The analysis revealed that the Ehlanzeni District experienced the highest level of flooding, covering …

Variable weather and implications for herbicide efficacy and yield loss due to weeds
… soybean production. In Chapter 2 we quantified rainfall and temperature variation on the efficacy of several common preemergence herbicides used individually and in combination on key Midwest weed species. Results demonstrated a rainfall threshold of 5–10 cm within 15 days of application of …

Modelli di preannuncio delle piene in piccoli bacini ed incertezze legate alla densita' della rete pluviometrica.
… river water levels. Moreover, real-time rainfall observations at high resolution in time and space are required to understand the watershed processes involved. However small catchments are generally scarcely instrumented and only a sparse rain gauge network is available. This work analyze …

Analysis of Soil Splash Erosion Under Simulated Rainfall
Threshold energy based on the regression results, required to initiate soil splash, was dependent upon soil type, with greater clay content soils exhibiting a greater threshold energy. Soil splash rate increased with increasing kinetic energy, with large differences between soils. Soil loss …
