Landscapes of Energy Acquisition: the Getting of Power
Secondary landscapes may of course include the use of the controlled water for irrigation, with all the subsequent changes elaborated in Chapter 13. The downstream nature of the river will also be affected since its silt content (and hence erosive power) will be radically lowered by its sojourn in the low-energy environment of the reservoir. The temperature of the watercourse may also be subject to change since thermal stratification occurs in large, still, water bodies and the draw-off into the turbines may come from a particular temperature level. This can affect the flora and fauna of the river below the dam.
