The importance of understanding the effects rainfall on different materials over time makes it essential to carry out controlled tests reduce analysis time. Rainfall simulators have been in use for decades and implemented as technology knowledge physical behavior water advanced. There are two main types simulators: gravity pressure simulators. In former, drop velocity is normally smaller than t...

This paper describes the application of Artificial Neural Networks (ANNs) as Data Driven Models (DDMs) to predict urban flooding in real-time based on weather radar and/or raingauge rainfall data. A 123manhole combined sewer sub-network from Keighley, West Yorkshire, UK is used to demonstrate the methodology. An ANN is configured for prediction of flooding at manholes based on rainfall input. I...

Abstract Stochastic rainfall generators aim to reproduce the main statistical features of at small spatial and temporal scales. The simulated synthetic series are recognized as suitable for use with impact analysis in water, agricultural, ecological management. Convection-driven precipitation, dominant certain regions world such intertropical belt regions, presents properties that require speci...

Runoff leads to the leaching of soil nutrients, transports the topsoil particles and deposits the sediments in water reservoirs. Recognition of different environmental factors affecting the runoff properties and water infiltration depth has a great importance concerning soil for the integrated management of watershed and the distinguishment of complex hydrological processes. Thus, this research...

Disturbed land surfaces are a major source of fine particulate matter in the air. Dust suppressants are applied to these surfaces to minimize the suspension of the particulate matter. The application of dust suppressants affects the runoff characteristics of these lands as well as the water quality of the runoff. A rainfall simulator has been designed to create rainfall, and to study the hydrol...

Abstrak. Potensi bahaya erosi pada lahan berlereng seperti perkebunan perlu kiranya dilakukan pengukuran dan perkiraan erosi. Metode salah satunya adalah model MUSLE (Modified Universal Soil Loss Equation) yang awalnya dikembangkan skala petak pertanian di Amerika Serikat, sehingga untuk mengetahui sejauhmana mampu memperkirakan maka akurasi tingkat dengan membandingkan dua plot percobaan tanam...

hairsine and rose (1991) developed a process-based soil erosion model which described the erosion transport of multiparticle sizes in sediment for rain-impacted flow in the absence of entrainment in overland flow. in order to test this model laboratory experiments were carried out in a detachment tray using simulated rainfall. three contrasting soil types were subjected to simulated rainfall at...

Rainfall is a driving force for the transport of environmental contaminants from agricultural soils to surficial water bodies via surface runoff. The objective of this study was to characterize the effects of antecedent soil moisture content on the fate and transport of surface applied commercial urea, a common form of nitrogen (N) fertilizer, following a rainfall event that occurs within 24 hr...
