Abstract:
... Accurate Quantitative Precipitation Forecasts (QPF) at high spatial and temporal resolution are a perquisite for urban flood prediction. Commonly Lagrangian extrapolation of the rainfall patterns recognized by radar data, forms the basis of such forecasts for the near future (up to 2 h lead time) – referred here as nowcasting. Nevertheless, due to the intermittent nature of the rainfall at such fi ...

Abstract:
... Debris flows caused by channel bed erosion present major hazards affecting life, livelihoods, and the built environment in mountainous regions. An efficient way to decrease hazard impact is through reliable hazard forecasts and appropriate early-warning strategies. Rainfall thresholds are fundamental in achieving reliable hazard forecasts. However, a lack of rainfall records often impedes the empi ...

To address the time consumption, this paper developed a novel method and calibration system to improve the TBR calibration efficiency. Two peristaltic pumps were adopted in this method: one pump provided some simulated rainfall intensities, ...

Abstract:
... Long-term droughts observed in southern Australia have changed relationships between annual rainfall and runoff and tested some of the assumptions implicit in rainfall–runoff models used in these areas. Predictive confidence across these periods is when low using the more commonly used rainfall–runoff models. Here we modified the GR4J model to better represent surface water–groundwater connection ...

When these volcanoes are in their post-shield or post-rejuvenated stage, erosion and subsidence dominate leading them towards a dramatic end, with their extinction as subaerial and transition to the guyot or razed island stage. To quantify the long-term growth and erosion rates affecting these volc ...

Abstract:
... Gully pots actively trap sediments transported by urban runoff to prevent in-pipe blockages and surface flooding. However, due to poor maintenance (resulting in sediment build-up) and increasingly extreme wet weather events, the scour of previously-deposited sediments from gully pots is identified as a potential contributor to EU Water Framework Directive failure. While basal sediment scour determ ...
