Why is catchment area important?

Why are catchments important? Catchments provide people, stock and flora and fauna with drinking water. They provide people with water for domestic and industrial use, including irrigation, and they cater for recreation and tourism. They may also include important cultural sites.

What is the function of a catchment area?

A catchment is an area of land where water collects when it rains, often bounded by hills. As the water flows over the landscape it finds its way into streams and down into the soil, eventually feeding the river. Some of this water stays underground and continues to slowly feed the river in times of low rainfall.

What are the main features of a catchment?

A catchment is an area of land, usually bounded by mountains, over which water flows and is collected by the natural landscape. In a catchment, all rain and run-off water eventually flows into a creek, river, lake, lagoon or the ocean. In some places small catchment areas join up to form a larger catchment.

Why are catchments important for collecting water?

Healthy catchments provide a source of clean drinking water, habitat for plants and animals, natural vegetation and waterways for recreation, reliable and clean water for livestock and irrigation, and opportunities for sustainable agriculture and industry.

What catchment area means?

1 : an area that serves to catch water. 2 : the geographical area served by an institution.

What are the types of catchment area?

Types of catchment areas Catchment areas generally fall under two categories, those that occur organically, i.e., “de facto” catchment area, as people are naturally drawn to a location and those that are established and modified by entities such as local governments or organizations.

How is catchment area calculated?

Calculating your catchment capacity This capacity can be calculated using the following formula: Annual rainfall (in millimetres) x Roof surface area (in square metres) = Roof catchment capacity.

How does a catchment system work?

Gravity causes all rain and run-off in the catchment to run downhill where it naturally collects in creeks, rivers, lakes or oceans. Rain falling outside the edge of one catchment is falling on a different catchment, and will flow into other creeks and rivers.

How do I find my catchment area?

Sizing a Catchment Area – The size of the catchment area or roof will determine how much rainwater that you can harvest. The area is based on the “footprint” of the roof, which can be calculated by finding the area of the building and adding the area of the roof’s overhang.

How can we manage and protect our catchment areas?

Living and working in the catchments

1. Weeds and pests – use organic herbicides and pesticides for control.
2. Trees and shrubs – plant or retain native trees and shrubs to help prevent soil erosion.
3. Riverbanks – protect plants on the banks of streams and rivers to provide a buffer against pollution.

What are the causes of catchment pollution?

As the human population increases, there is an increase in pollution and catchment destruction. inadequate sewage collection and treatment; Increase in fertilizers to grow more food. These results in an increase in nutrients (nitrates and phosphates) in the water which causes enhanced plant growth (algal blooms).

What does good catchment area mean?

In human geography, a catchment area is the area from which a location, such as a city, service or institution, attracts a population that uses its services and economic opportunities.

Why are catchment areas so important when buying a house?

In Belgravia, properties near to schools tend to go far more quickly with families that have children of schools age.

“Many parents will pay more for a property in the catchment areas of popular schools….Merton Local Authority for example will offer the child a place in a state school if they don’t get their first choice, but this may not be suitable for the parents.

Which is an example of a catchment basin?

A watershed (catchment or drainage basin) is an area of land where all of the precipitation that falls, less the water lost to evaporation and deep aquifer recharge, eventually flows to a single outlet. A watershed encompasses both surface and subsurface components of water drainage that contribute to stream discharge.

How is waste water directed to the catchment?

The catchment used for this case study is known locally as the Berlin VIII catchment. The combined flows produced by the catchment are directed to a main pumping station (Béraud et al., 2010 ). The pumping station has to direct the waste water to three treatment stations represented as a single one via a variable speed pump.
