Water and its use in early history:
»There is no life without water«- this fact all people knew instinctively since the beginning of mankind. People were supplied from local resources, which already very early were improved by digging wells. People in antiquity studied the natural phenomena, analysed and interpreted them in an excellent way. This resulted in a splendid water management, which is shown at Egypt and the Marib dam as examples.
When the local water resources were no longer sufficient to meet the water demand of the societies there have been only two methods to increase the available water, i.e. the local and temporal transfer. These transfers are also demonstrated at various examples.
