Water-flow accounts as part of material and energy-flow accounts in Germany
This paper  describes the concepts, data sources and methods of the water-flow accounts of the Federal Statistical Office as a part of the German material and energy-flow accounts . The water flow accounting system represents in physical units the water flows, caused by economic activities, from nature to the economic system (raw materials), within the economic system, and from the economic system to nature (residuals). In the second part of this paper, data are presented on the development of important national-economy aggregates of the water-flow accounts for 1960 to 1995. In addition, detailed results in a breakdown by homogeneous branches are shown for the year 1995.
