What are the factor affecting run off?

What are the factor affecting run off?

Meteorological factors affecting runoff: Rainfall intensity. Rainfall amount. Rainfall duration. Distribution of rainfall over the watersheds.

How and why humans affect run off?

Human activities can affect runoff In addition to increasing imperviousness, removal of vegetation and soil, grading the land surface, and constructing drainage networks increase runoff volumes and shorten runoff time into streams from rainfall and snowmelt.

What causes excess runoff?

Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.

What are the negative impacts of runoff?

How human activities affect river discharge?

Impermeable man-made surfaces – Concrete and tarmac can cause rivers in urban drainage basins to have a higher discharge due to higher amounts of surface runoff. Speed is also increased due to drainage systems and ground.

How human activities change the river discharge?

Sulfur dioxide and nitrous oxide emitted from factories and power stations enter river systems through acid rain. Sewage and effluent are discharged into rivers in some areas. Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH.

How do humans impact the upper course of a river?

The development of industry, like urbanisation, leads to an increase in impermeable surfaces and therefore greater surface run-off. Chemical weathering can increase in river landscapes due to air pollution from factories and vehicles making rainfall more acidic.

Why is it important to protect rivers?

They store and clean the water that’s crucial for people and wildlife. Healthy freshwater environments supply water for drinking, growing crops, manufacturing, energy and transport. They also help to prevent erosion, dispose of waste and provide natural protection from flooding.

What is the disadvantages of ocean?

Disadvantages – Sometimes there will not be a lot of waves (which means no energy), It could interfere with ocean ecosystems in the area of the currents, and the temperature is raised wherever ocean currents are happening (which could also ruin an ecosystem).
