By setting up three experimental watersheds, Slovenia obtained its ground for further development of the hydrological science.By setting up three experimental watersheds, Slovenia obtained its ground for further development of the hydrological science. The experimental watersheds have been equiped with modern measuring equipment for precise measurements of precipitation, intercepted precipitation, discharges, erosion and water quality.The experimental watersheds have been equiped with modern measuring equipment for precise measurements of precipitation, intercepted precipitation, discharges, erosion and water quality. Thus contemporary experimental base was established and used for scientific research and at the same time provided support to the water management, teaching and studying process.Thus contemporary experimental base was established and used for scientific research and at the same time provided support to the water management, teaching and studying process.
