Impact of River Rejuvenation on Economic Activities: Geomorphology

Impact of River Rejuvenation on Economic Activities: Geomorphology On this page, we go through how revitalizing rivers can affect a nation’s economy. River revitalization is covered in the Geomorphology section of Grade 12 Geography. When a river’s velocity and erosive force increase, which is more pronounced through vertical or downward erosion, river rejuvenation occurs.

How River Rejuvenation process impact the Economic Activities

Now let’s look at how the river rejuvenation process impacts the economic activities of a country. River rejuvenation process causes the following to form: canyons and georges, waterfall, river terrace. Now lets look at how these land features affect the economy:

Canyons and gorges impact on the economy

• Canyons are important to paleontology, or the study of fossils.
• The existence of canyons and georges in a country boosts the tourism sector of the economy. Tourists come to see the canyons, spend their money, buy local products which ultimately create employment

The impact of Waterfall in the economy

• Waterfalls attract tourists who end up buying our local produce and hence we earn money.
• The Waterfalls can also be used to produce hydro electricity power.
• Fishing can be carried out on waterfalls and the fish sold to get income and improve on the living standards of people.

The benefits of a river terrace:

• Terraces reduce slope length, reducing the power of flowing water to erode soil.
• By limiting soil erosion, terraces also improve water quality by reducing sediment and phosphorus delivered to streams, rivers, and lakes.
