Název v původním jazyce

Calibration of the new large field rainfall simulator

Popis výsledku v původním jazyce

The Department of Landscape Water Conservation at the CTU in Prague has owned rainfall simulator since 1999. Over time, the equipment has been modified and new ones developed. The latest device is a new large field rainfall simulator with an experimental plot of 4 x 2 m. Testing and calibration has been ongoing in recent years. The device includes a swiping and pulse nozzle system. It has adjustable rainfall intensity and kinetic energy is depending on the type of nozzles used. The nozzles currently used are those used on the old large field rainfall simulator for the pulse system (Spraying system WSQ40) and new previously unused nozzles for the swing system, which are similar to those used on the small rainfall simulator. For calibration, 20 rain gauges and disdrometer LPM by Thies were used. In particular, the expected benefits of the new device for routine work are: low operator manpower requirements, great variability of use due to the two rainfall generation systems, improved sensors logging capability and greater durability due to the design. This research was supported by the projects QK22010261, CK04000144, by the Grant Agency of the CTU in Prague SGS23/155/OHK1/3T/11 and project CZ.02.1.01/0.0/0.0/16,017/0002626.
