Consequences of altering rivers

Consequences of altering rivers Loss of habitats Wildlife that depends on natural river conditions may decline. Fewer plant and animal species can survive after changes. Disruption to fish migration Species such as salmon may struggle to reach spawning grounds. Reduced natural river processes Rivers become less able to shape landscapes naturally. Increased erosion Altered flows can wear away riverbanks. Flooding Preventing floods in one area can increase flooding in another. Changes to water quality Pollution can become concentrated or spread differently. Impact on communities People living downstream may experience water shortages or changes in river behaviour.
