What is surface flow?
Surface flow is when water from the rain runs on the surface into the ocean.
Distinguish between interception and overland flow?
interception-is the store of water droplets by plant leaves as rainfall occurs; overland flow-describes water which runs downslope in unconcentrated form such as sheet floods,rills and rivulets._by Malcom kahonde
How does surface tension and viscosity affect the flow of liquids?
Viscosity is the resistance of flow and surface tension is the lateral force of the bonds between the molecules
How are local and prevailing winds similar?
local and prevailing winds are similar because they both flow in the same direction?
Does lava flow to the surface and become a magma?
No. Magma flows to the surface and becomes lava.
Running water above earth surface?
surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow)
What are human causes of overland flow?
Human causes of overland flow include urbanization, which increases impervious surfaces like roads and buildings, preventing water from infiltrating into the ground; deforestation, which reduces vegetation that helps absorb and slow down water; and poor land management practices such as excessive tilling or removal of natural water-absorbing features like wetlands. These activities can exacerbate overland flow and lead to increased flooding and erosion.
What does overland flow mean?
The surface flow is of two types 1. saturated flow, which is caused due to saturation of soil and 2. Hortonian flow, which is caused due to excess rainfall intensity. When the rainfall intensity exceeds the infilatration capacity of the soil, Hortonian flow takes place.
What is the nature of the Hortonian Overland Flow?
Hortonian Overland Flow is characterized by pooling of water caused rainfall exceeding the rate at which water infiltrates the ground. It is most common in urban areas with paved surfaces.
That water that moves across Earths surface after rainfall is called what?
runoff

Differentiate between open channel flow and pipe flow-?
The open channel flow has a free surface whereas the pipe flow has a closed surface.
What are different kinds of runoff?
1. Surface Runoff: It is that portion of rainfall which enters the stream immediately after the rainfall. It occurs. When all losses are satisfied and if rain is still continued, with the rate greater than in filtration rate; at this stage the excess water makes a head over the ground surface (surface detention) which tends to move from one place to another, known as overland flow. As soon as the overland flow joins to the streams, channels or oceans, termed as surface runoff.2. Sub - surface Runoff: That part of rainfall, which first leaches into the soil and moves laterally without joining the water - table to the Streams Rivers or oceans is known as sub - surface runoff. Sometimes sub - surface runoff is also aerated under service ninoff due to reason that it takes very title time to reach the river or channel in comparision to ground water. The sub - surface runoff is usually referred as interflow.3. Base flow: It is delays flow, defined as that part of rainfall which after talling on the ground surface in fill rated into the soil and meets so the water table and flow to the streams oceans etc. The movement of water in this type of runoff is very slow that is why it is also referred as delayed runoff. It takes a long time to join the rivers or oceans. Some times base flow is also known as ground water flow.
Differentiate between open channel flow and pipe flow?
The open channel flow has a free or rather open surface whereas the pipe flow has a closed surface.
Who are some famous hydrologists?
Robert E. Horton From overland flow, interception loss, and stream orders, Horton is the grandfather of hydrology
Are base flow same as groundwater?
Base flow is the portion of streamflow that comes from groundwater discharge, but it is not exactly the same as groundwater. Groundwater refers to the water stored underground in aquifers, while base flow specifically refers to the contribution of groundwater to streamflow during dry periods when surface runoff is low.
