However, the development of high-fidelity rainfall simulators remains a challenge. This study aimed to design, construct, and calibrate a spraying-type rainfall simulator and validate assessment criteria optimized for soil erosion research. The simulator’s design is based on a modified simulator model previously described in the literature and following the defined criteria. The calibration of the simulator was conducted in two phases, on slopes of 0° and 15°, measuring rainfall intensity, drop size, and its spatial distribution, and calculating drop falling velocity, kinetic energy, and momentum. The simulator consists of structural support, a water tank, a water-moving mechanism, a flow regulation system, and sprayers, contributing to its simplicity, cost-effectiveness, durability, rigidity, and stability, ensuring smooth simulator operation. The calibration of the rainfall simulator demonstrated that rainfall intensity increased from 1.4 mm·min<sup>−1</sup> to 4.6 mm·min<sup>−1</sup> with higher pressure in the hydraulic system (1.0 to 2.0 bar), while spatial uniformity remained within 79–91% across different nozzle configurations. The selected Rain Bird HE-VAN series nozzles proved highly effective in simulating rainfall, achieving drop diameters ranging from 0.8 mm to 1.9 mm, depending on pressure and nozzle type. The rainfall simulator successfully replicates natural rainfall characteristics, offering a controlled environment for investigating soil erosion processes. Drop velocity values varied between 2.5 and 2.9 m·s<sup>−1</sup>, influencing kinetic energy, which ranged from 0.6 J·min<sup>−1</sup>·m<sup>−2</sup> to 2.9 J·min<sup>−1</sup>·m<sup>−2</sup>, and impact momentum, which was measured between 0.005 N·s and 0.032 N·s. The simulator design suggests that it is suitable for future applications in both field and laboratory soil erosion research, ensuring repeatability and adaptability for various experimental conditions. Calibration results emphasized the significance of nozzle selection and water pressure adjustments. These factors significantly affect rainfall intensity, drop size, kinetic energy, and momentum, parameters that are critical for accurate erosion modeling.This research was financially supported by the Ministry of Science, Technological Development and Innovation of Republic of Serbia (Contract No.: 451-03-66/2024-03/200026, 451-03-137/2025-03/200169, 451-03-136/2025-03/200169), by the Science Fund of the Republic of Serbia, No. 7043, Urban Forest Soil Indicators as a tool for Climate-Smart Forestry—UrbanFoS, and the Spanish Ministry of Science, Innovation and Universities through the research contract RYC2022-035489-I.Peer reviewedMultidisciplinary Digital Publishing InstituteMinistry of Science, Technological Development and Innovation (Serbia)Science Fund of the Republic of SerbiaMinisterio de Ciencia, Innovación y Universidades (España)Rončević, Vukašin [0000-0001-6792-1144]Živanović, Nikola [0000-0003-0340-5516]Sadeghi, Seyed Hamidreza [0000-0002-5419-8062]Fernández-Raga, María [0000-0002-8228-6705]Prats Alegre, Sergio [0000-0002-7341-877X]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202520252025info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/396424https://api.elsevier.com/content/abstract/scopus_id/105010512881reponame:DIGITAL.CSIC.
