In Kenya changes to natural river flows and degraded water quality are most likely environment problems related to

The answer is:

One of the strongest reasons for changing the natural flow of rivers and degraded water quality, is mainly due to the growing quest of Kenia to achieve the status of industrialization. Through this massive industrialization and incessant search for development, it led to the appearance of other problems related to water quality, such as pollution. That changes strongly the dynamic of the flows and water quality.

Kenya is a that country already suffers from a tremendous shortage / scarce of water and the per capita income of water is far below world standards. This issue only gets worse and it isaggravated by seasonal fluctuations in water availability, which is more correlated with seasonal patterns of rainfall in most parts of the country.
