Rainfall noise simulation and mitigation

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2022
A newly constructed and otherwise well-regarded building suffered from excessive rain noise in open areas where the roof deck was exposed. A single major rain event was used to characterize the existing condition, making use of a handheld sound level meter, mobile phone recordings, and weather radar data and corresponding rainfall rates.

Rainfall Simulation in Flight View

International Journal of Digital Content Technology and its Applications, 2011
An improvement is made to traditional particle system technology in rainfall simulation. In order to improve the authenticity and flexibility of rainfall simulation and speed up the rendering speed, the particle rotation, particle dynamic texture, dynamic color etc. are introduced. The structure of particles is simplified.

Theoretical prediction of rainfall intensity for a small rainfall simulator

2022 IEEE Workshop on Metrology for Agriculture and Forestry (MetroAgriFor), 2022
In this contribution, a theoretical approach was developed for predicting rainfall intensity for a small rainfall simulator. The developed equation was tested for two different devices and different pressure head and water temperature values. The proposed relationship was found to have a good predictive ability of rainfall intensity.

A Continuous-Application Rainfall Simulator

Transactions of the ASAE, 1985
ABSTRACT A simple, inexpensive, continuous-application rainfall simulator was developed using air injected into a water conduit. The effect of injecting air was to maintain higher discharge pressures enabling better uniformity without increasing the rainfall intensity.

RAINFALL SIMULATOR FOR LABORATORY STUDIES

Applied Engineering in Agriculture, 2000
Numerous types of rainfall simulators have been used to study the fundamental behavior of sediment transfer and chemical movement in soil from rainfall. For results of these studies to be representative, it is essential that the artificial rainfall have characteristics similar to that of natural rainfall.

A virtual discrete rainfall simulator

Environmental Modelling & Software, 2012
This paper describes the development and test of a numerical rainfall generator for use as a preprocessor for small-scale spatialized simulation of processes induced by rain, such as soil erosion or soil surface crusting. This generator produces series of individual raindrops respecting both a given hyetograph and a spatial distribution, and satisfying

Stochastic Simulation of Daily Rainfall

1975
Abstract: The design of many water resources projects requires knowledge of possible long-term rainfall patterns. In this project a stochastic model based on a first order Markov chain was developed to simulate daily rainfall at a point. The model is applicable to any point in Kentucky (and other areas with similar rainfall patterns).

MICROCOMPUTER-CONTROLLED LABORATORY RAINFALL SIMULATOR

Transactions of the ASAE, 1990
A microcomputer-controlled rainfall simulator is described. The simulator modules utilize oscillating nozzles similar to the simulators described by Neibling et al. (1981) and Moore et al. (1983). The unique feature of this simulator is full computer control using a parallel printer port rather than a special digital or analog output board.

Error influence of radar rainfall estimate on rainfall-runoff simulation

Stochastic Environmental Research and Risk Assessment, 2015
Radar systems have been widely employed to measure precipitation and predict flood risks. However, radar as a rainfall measuring device and the produced rainfall estimate contain uncertainties and errors resulting from sources such as mis-calibration, beam blockage, anomalous propagation, and ground clutter.

Rainfall Intensity-Dependent Infiltration Rates on Rangeland Rainfall Simulator Plots

Transactions of the ASABE, 2008
Most implementations of infiltration equations with rainfall-runoff models use a hydraulic conductivity parameter that is constant for a given rainfall event. However, plot data from rainfall simulator experiments and natural rainfall events have shown that infiltration rates can increase with increasing rainfall rate instead of decreasing with time or
