 | | A river may have its source in a spring, lake, from damp, boggy places where the soil is waterlogged, from glacial meltwater, or simply from rain flowing off impermeable rock or man-made surfaces. |
 | | Rivers have been used by man since the dawn of civilization as a source of water, for food, for transport, as defences, as a source of power to drive machinery, and as a means of disposing of waste. |
 | | The flora and fauna of rivers have developed to utilise the very wide range of aquatic habitats available from torrential waterfalls through to lowland mires Although many organisms are restricted to the fresh-water in rivers, some, such as Salmon have adapted to be able to survive both in rivers and in the sea. |
