Fresh water catchment and runoff

 

An area of land that is used to collect rain water is called a catchment. There can be artificial and natural catchments. Artificial catchments are made in areas where infiltration of runoff zone is higher. In natural conditions, water flowing over landscapes finds its way into streams, into the soil, and eventually the river. Not all water flows over landscape, some remain underground and keep feeling the river when rainfall is low. Precisely, every inch of land on the earth serves like a catchment.

 

Artificial ones are fresh water catchments which help in rainwater harvesting. Not all catchments are same in size. They range greatly in size from small urban sub-catchments to larger and massive catchments that may span across states.

 

In artificial settings, fresh water catchment & runoff are interrelated. Catchments are essential in areas with high infiltration rate. In natural conditions, catchments are complex and any event in one part of the catchment can impact other parts. In the past few years, big changes in catchments have been noticed. Many of the changes are because of human activities. Many natural landforms like small creeks and bushlands have been utilized for houses, roads, and other structures. It has great impacts on creeks and rivers.

 

Impact of human activities on water catchments

 

Human activities have a great impact on the health of water catchments. Various activities, particularly – industry, building, and farming – can have a severe impact on the systems that supplies drinking water. Therefore, regularity authorities are concerned to manage and protect water catchments to ensure a supply of high-quality water. They work together with local councils, landholders and government agencies to ensure daily activities in the catchment do not cause harm to the water.

 

Land environment plans can help manage resources efficiently to minimize the impact on environment. Land IQ Insights experts can help with Fresh water catchment and runoff and land environment plans.
