When the ground water flow out of the earth surface as a form of spring.
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)
ground water Groundwater is located beneath the soil surface. A sustainable amount of ground water creates an aquifer. The point at which the soil and rocks become completely saturated is the water table. Groundwater will flow to the surface naturally. The study of groundwater is hydrogeology.
Bed rock is the layer of rock through which ground water cannot flow.
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.

Where the ground water leakage direction meet into the surface water is called Base flow.
A runoff is precipitatoin soaks into the ground, precipitation can also run over the ground and flow into streams, rivers, lakes, and eventually the ocean.

surface runoff
Surface water flows downhill or seeps into the ground becoming groundwater. The natural flow of surface water is downhill or seaward. See the related link for more information.
Ground water is the water that occupies pore and void space below the surface of the earth. This water will flow if their is a suitable pathway (e.g. a porous and permeable rock forming an aquifer) from a region of high to low hydraulic head.
Surface flow is when water from the rain runs on the surface into the ocean.

Into ground waters and eventually the rivers and the seas.
Due to gravity, water will always flow to the lowest level. Therefore, as part of the water cycle, rain will flow downhill and eventually reach the sea. The rain will also top-up the ground water-table, and fill lakes and reservoirs.
