Abstract Rainfall-induced slope instabilities are ubiquitous in nature, but simulation of this type hazards with centrifuge modelling still poses difficulties. In paper, we introduce a rainfall device for initiating failure medium-sized centrifuge. This system is simple, robust and affordable. An array perforated hoses placed close above the model surface to generate raindrops. The intensity de...

Widespread observations of ecohydrological separation are interpreted by suggesting that water flowing through highly conductive soil pores resists mixing with matrix storage over periods days to months (i.e., two ‘water worlds’ exist). These interpretations imply heterogeneous flow can produce in soils, yet little mechanistic evidence exists explain this phenomenon. We quantified the between m...

The growing demand for efficient and effective mosquito control requires a better understanding of vector population dynamics and how these are modified by endogenous and exogenous factors. A long-term (11-year) monitoring data set describing the relative abundance of the saltmarsh mosquito (Aedes vigilax) in the greater Darwin region, northern Australia, was examined in a suite of Gompertz-log...

The role of leaf litter in hydrological processes and soil erosion of forest ecosystems is poorly understood. A field experiment was conducted under simulated rainfall in runoff plots with a slope of 10%. Two common types of litter in North China (from Quercus variabilis, representing broadleaf litter, and Pinus tabulaeformis, representing needle leaf litter), four amounts of litter, and five r...

High-resolution rainfall forecasting— the ability to predict rainfall intensities at enhanced resolution in space and time—is one of the most difficult, but also most useful, problems in applied meteorology and hydrology. Such forecasting could help scientists predict floods and manage water resource operations. Despite its well-known benefits,1 however, scientists have made little progress ove...
