Design of the HYREX raingauge network

Dense raingauge experiments in the past have experienced difficulties in th e automated recording of rainfall amount and timing which with the benefit of modem instrument technology are now less problematic. The HYdrological R adar EXperiment, HYREX, provided a timely opportunity to design and impleme nt a dense raingauge network in support of rainfall measurement and modelli ng research studies concerned with the use of weather radar in hydrology. T he principles and random function theory underlying the design of this rain gauge network over the Brue catchment in south-west England are detailed in this paper.
