Steep slopes consisting of disturbed soil are very often found in construction, landfill, and surface mining situations. Although legislation and economics dictate that vegetative cover be established on these slopes as rapidly as possible, the occurrence of large rainfall events during critical periods of vegetation establishment can frequently cause extensive soil loss. Sediment generated fro...

In previous work, we have proposed a constructive methodology for temporal data learning supported by results and prescriptions related to the Embedding Theorem, and using the Singular Spectrum Analysis both in order to reduce the effects of the possible discontinuity of the signal and to implement an efficient ensemble method. In this paper we present new results concerning the application of ...

Abstract: Runoff and sediment was measured for a chaparral community on the Prescott National Forest in the summer of 1979...

Rain attenuation at 355.2 GHz in the terahertz wave range was measured with our new 355.2 GHz measuring system under rainfall intensities up to 25 mm/hr. Rain attenuation coefficients were also calculated using four raindrop-size distributions, e Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull distributions, and using a specific rain attenuation model for prediction methods rec...

High spatiotemporal resolution rainfall is needed in predicting flash floods, local climate impact studies and agriculture management. Rainfall estimation techniques like satellites the commercial microwave links (MWL) have independently made significant advancements high estimation. However, their combination for has received little attention, while it could benefit many applications ungauged ...

Rain-induced attenuation of microwaves poses a serious challenge to signal availability beyond 10 GHz frequencies. The challenges are even more pronounced in the subtropical and tropical regions with high intensities rain which is accompanied thunderstorms. Nigeria has an equatorial climate, identified by controlling rainfall. Rain significant factor various communication above Therefore, for e...

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...

ABSTRACT This work presented the development and testing of a large-scale rainfall simulator (LSRS) to be used as research tool on rainfall-runoff associated transport processes in urban areas. The consists pressurized water supply system which supplies set 16 full-cone nozzles. Artificial with different intensities can produced over an area 100 m2 V shape. assembly is housed tailor-made acryli...

This paper describes the second part of a study to document the sensitivity of the modeled regional moisture flux patterns and hydrometeorological response of the North American monsoon system (NAMS) to convective parameterization. Use of the convective parameterization schemes of Betts–Miller–Janjic, Kain–Fritsch, and Grell was investigated during the initial phase of the 1999 NAMS using versi...

Synthetic design storms are often used to plan new drainage systems or assess flood impacts on infrastructure. To simulate extreme rainfall events under climate change, can be modified match a different return frequency of as well temporal distribution intensities. However, the same magnitude change intensities is applied in space. Several hydrological applications limited by this. Climate urba...
