英文摘要 | Study region: The study was carried out in Fowlers Gap (New South Wales, Australia) within a 400 km2 arid zone catchment approx. 110 km north of Broken Hill. Study focus: A comprehensive dataset of 10 s rainfall encompassing 17 rain gauges spanning over a decade (from 2013 to 2023) was meticulously analysed in combination with climate and stream levels and supplemented by daily camera images of the creek. New hydrological insights for the region: 64.6% of the rainfall flows to the creek, with the remainder lost before reaching the creek. Within this 64.6%, there were 67 individual flow events, comprising 47.7% of rainfall (35 events) associated with fronts and 16.9% (32 events) linked to local cumulonimbus storm cells. A fundamental characteristic of these flow events is their very rapid response, which appears to be independent of antecedent moisture content. The spatially averaged intensity of rainfall events experienced an approximate 200% increase, rising from 1.6 mm/h in mid-2013 to 4.8 mm/h by mid-2023. This noteworthy change is attributed to climate change. Despite the projected decrease in overall precipitation for the region, this observed rise in intensity aligns with the broader trend of global warming accelerating the water cycle. |
