Document Summary
There are close natural links between landscape and water resources. Water that condenses contributing to cloud formation reaches the ground in the form of precipitation and returns to the atmosphere through transpiration and evaporation. Water that has reached the ground can infiltrate, percolate and be reabsorbed by plants. The water will also lead to the formation of groundwater and a water table. Rocks and soils will be saturated with water and eventually water that flows as groundwater will form springs as the water connects with the topography. The surface runoff will eventually lead to the ocean. Precipitation contributes to the formation of groundwater. The groundwater saturates rocks and soil and eventually flows to springs and eventually the ocean. The global international water"s assessment report has studied these linkages between landscape and water. The destruction of habitats is involved in 18% of the cases of regions facing water related issues.
