Summary Introduction

To explain:

The speed of water flow caused by the dam removal determines which species can live in a river.

Introduction:

Ecosystem is defined as the interaction between the living organisms and their environment. When the dam wall is built in the river, it prevents fish migrations. Some species are completely separated from spawning habitats and rearing habitats. Sediments are trapped by the dam, which is critical for sustaining habitats in the downstream. If the dam is removed, the removal causes large and rapid changes in biodiversity.
