In this study, the authors used Tropical Rainfall Measuring Mission precipitation radar (TRMM PR) data to investigate changes in the actual (attenuation corrected) surface backscattering cross section ( e) due to changes in surface conditions induced by rainfall, the effects of changes in e on the path integrated attenuation (PIA) estimates by surface reference techniques (SRTs), and the effect...

gross rainfall (gr) partitioning into throughfall (tf), stemflow (sf) and interception loss (i) was studied in a pure oriental beech (fagus orientalis lipsky) forest located in the central caspian region of northern iran. measurements were performed on a rainfall event basis in a 5625 m2 plot of the kheyrud forest research station of tehran university during 2008 and 2009 growing seasons. gr wa...

An approach for predicting incident durations that are susceptible to severe congestion, the occurrence of secondary incidents, and their joint effect is proposed. First, a fuzzy entropy feature selection methodology is applied to determine redundant factors and rank factor importance with respect to their contribution on the predictability of incident duration. Second, neural network models fo...

High rainfall intensity during the dry season can cause floods and landslides that a lot of loss property life as happened in Purworejo. Generally, with little rainfall, heavy rain June is very rare, therefore disaster anticipation will be better if precursor identified. This research aims to obtain high-intensity precursors south Central Java, especially Identification used classifying for 10 ...

Throughfall volumes and incident rainfall were measured between 23 August and 2 December 2004 as well as from 6 January to 15 April 2005 for individual rain events of differing intensities and magnitudes in an open tropical rainforest in Rondônia, Brazil. Temporal patterns of throughfall spatial variability were examined. Estimated interception was compared to modeled interception obtained by a...

rainfall is recognized as one of the main triggering factors of landslides. researchers have long attempted to determine the amount of precipitation required to trigger slope failures. one of the landslide zones in iran is chaharmahal & bakhtiari province where many landslides cause high casualties in recent decades. it is significant that most of these landslides occur after a rainy period...
