Intensity-duration-frequency (IDF) curves representing the variation of magnitude extreme rainfall events with a return period and storm duration are widely used in hydrologic infrastructure design, flood risk management projects, climate change impact studies. However, many locations worldwide, short-duration rainfall-observing sites long records do not exist. This paper introduces new methodo...

We analyze how extreme rainfall intensities in the Eastern United States depend on temperature T, dew point temperature Td, and convective available potential energy CAPE, in addition to geographic sub-region, season, and averaging duration. When using data for the entire year, rainfall intensity has a quasi Clausius-Clapeyron (CC) dependence on T, with super-CC slope in a limited temperature r...

Depth-duration analysis, such as accomplished for rainfall, can be useful in the analysis of infiltration of rainfall. The assessment of infiltration depth-duration in terms of return frequency is of interest. In this paper, depth-duration values of daily rainfall infiltration are estimated using the National Resources Conservation Service (NRCS) Curve Number (CN) approach for estimating daily ...

the objectives of this study were to understand the rainfall characteristics of thewind-water erosion crisscross region on the northern loess plateau, china, to provide basisfor the studies on mitigation of soil erosion, estimation on surface water resources andlocal hydrological circle, etc. the liudaogou catchment with representative climatic andhydrologic conditions of wind-water erosion cri...

© The Ecological Society of America www.frontiersinecology.org T is a crucial need to understand ecological water balances, both in the present and in the future. This balance is currently shifting, as economies rapidly develop and urbanization accelerates (Hubacek and Sun 2005). In the future, global climate change and the resulting uncertainties will only add to the urgency of finding accurat...

We are designing a system to forecast rainfall-induced landslides in Italy. The system is based on a set of rainfall thresholds for the possible initiation of landslides, and an ensemble of small scale landslide hazard and risk zonations. Rainfall thresholds include existing and new, national, regional and local empirical thresholds of the intensity-duration (ID) and normalized-ID types. The ne...

Based on the hourly precipitation observed from ∼1800 automatic rain gauges during 2013–2017, characteristics of diurnal variation and underlying mechanisms over Jiangsu Province, eastern China, warm season (May to September) have been revealed in this study. Results show that amount (PA), frequency (PF), intensity (PI) are zonally distributed Jiangsu. The shows distinct cycle zonal distributio...
