What stormwater is, how it impacts our rivers, and how we can better manage it as a resource, rather than a waste product. Long histories of human impact (> 1000 years) are also evidenced by the reconstructions for the Yellow River, Yangtze River, the Ebro River and the Mississippi River, based on sedimentary evidence from deltas and analysis of available sediment records (cf. African Journal of Aquatic Science: Vol. (1987), Saito et al. Effects of human activities on the Waterval River, Vaal River catchment, South Africa. (iii) When rivers flood, they destroy a lot of property or crops and may displace people leading to loss of human life.

There is no area environment in which human have not interfered … They include pollution, climate change, urban growth, and landscape changes such as deforestation. (2004). 29, No. ABSTRACT The present research work has highlighted the human impact on the river systems. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources. These and other human impacts alter the natural variability of river flows. This often happened at the expense of the environment, which started deteriorating once humans took over the world. Water resources face a host of serious threats, all caused primarily by human activity. Untreated human sewage teems with salmonella, hepatitis, dysentery, cryptosporidium, and many other infectious diseases. Forgotten Legacies: Understanding Human Influences on Rivers - water quality has been largely ignored, especially in terms of policy instruments to enable and empower authorities to protect and manage this critical aspect of freshwater (Hattingh and Claassen 2008). People have always aimed higher and tried to become more prosperous. Globally, rivers and streams are being drained due to human use and climate change. Canal polluted by raw sewage. 1, pp.
