Knowledge of variation in soil properties from each event to another is very important for the determination of critical periods during which soil is susceptible to erosion processes. This study was carried out to investigate soil loss in sequential rainfall events in Zanjan Province. Toward this, ten soil textures samples were taken and were transported to small plots (60 cm×80cm) with 2...

This paper presents rainfall-induced landslide thresholds and predicts landslide hazard in Kuala Lumpur metropolitan city and surrounding areas. Landslide events from 2000 to 2012 were collected. The long and short antecedent rainfall days were prepared for landslide and non-landslide days simultaneously. First, threshold analysis was conducted by using data obtained from rainfall stations loca...

This study investigates the role of soil moisture on the threshold runoff response in a small headwater catchment in the Italian Alps that is characterised by steep hillslopes and a distinct riparian zone. This study focuses on: (i) the threshold soil moisture-runoff relationship and the influence of catchment topography on this relation; (ii) the temporal dynamics of soil moisture, streamflow ...

Traditional coastal flood hazard studies do not typically account for rainfall-runoff processes in quantifying and related cascading risks. This study addresses the potential impacts of antecedent rainfall-runoff, tropical cyclone (TC)-driven rainfall, TC-driven surge on total water levels its influence delineating a transition zone two distinct basins southeastern Louisiana (Barataria Lake Mau...

among different models for runoff estimation in watershed management, the soil conservation services-curve number (scs-cn) method along with its modifications have been widely applied to ungauged watersheds because of quickly and more accurate estimation of surface runoff. this approach has been widely accepted by hydrologists, water resources planners, foresters, and engineers, as well. theref...

A comprehensive framework is developed to assess the flood types, their spatiotemporal characteristics and causes based on the rainfall statistics, antecedent flow conditions, and atmospheric teleconnections. The Missouri River Basin (MRB) is used as a case study for the application of the framework. Floods are defined using the multivariate characteristics of annual peak, volume, duration, and...

avicenna has divided the conditionals to the real cogent (i.e. with possible antecedent) and the verbal cogent (i.e. with the impossible antecedent). denying the truth of the latter, he caused controversies among moslem logicians. at the paper, we report the controversies, analyze the real and verbal cogent conditionals, formalize them in modern modal and relevant logics, and finally, defend id...

Simulated rainfall was used to study infiltration rates and sediment production of28 plant communities and soils of five watershed areas in central and eastern Nevada. Two antecedent moisture conditions were used: soil initially air dry and initially at field capacity. InfiltratIOn rates and sediment production of the various soils are largely controlled by extent and surface morphology of dune...

We have explored the role of individual elements of the hypothalamic pituitary adrenal axis on the pathogenesis of hypoglycemia-associated autonomic failure. Five groups of male Sprague-Dawley rats were used. Control animals had 3 days of sham treatment followed by a hyperinsulinemic/hypoglycemic glucose clamp on day 4. A second group underwent 3 days of antecedent insulin-induced hypoglycemia ...
