Three Phases of Utilisation
The report of the Working Party on Mineral Resources (1964) states that past work for the appraisal and utilisation of water resources has followed three phases:
Early single-purpose developments largely for hydro-electric and municipal supplies:
From 1944, the soil conservation and rivers control phase in which widespread community developments, including an intensification in the network of river gauging and meteorological stations, were initiated through national work and by newly established local authorities:
From 1959, a phase in which the collection and publication of hydrologic data suitable for multi-purpose planning was introduced and undertaken comprehensively.
The third phase has been patterned on methods used by the Water Resources Division of the United States Geological Survey where the work is organised in four branches dealing with surface water, ground water, quality of water, and general hydrology.
