Runoff transfer of landwater to the oceans
Animation by: Bramer
Runoff is the movement of landwater to the oceans, chiefly in the form of rivers, lakes, and streams.
runoff"The water, derived from precipitation, that ultimately reaches stream channels.
Runoff: The movement of water across the earth's surface or just beneath the surface coming from liquid precipitation or the melting of ice/snow.
Runoff That part of precipitation that flows toward streams on the surface of the ground or within the ground. Runoff is composed of base flow and surface runoff.

Total runoff Surplus water that flows across a surface toward stream channels; formed by sheet flow, combined with precipitation and subsurface flows into those channels.
Surface Runoff: The part of runoff, caused by precipitation and/or snowmelt, that moves over the soil surface to the nearest stream channel. Rain that falls on the stream channel is often lumped with this quantity.
Inches of Runoff
In hydrologic terms, the volume of water from runoff of a given depth over the entire drainage
INCR ...
recharge The process by which water is added to a reservoir or zone of saturation, often by runoff or percolation from the soil surface.
Direct RunoffIn hydrologic terms, the runoff entering stream channels promptly after rainfall or snowmelt. Superposed on base runoff, it forms the bulk of the hydrograph of a flood.
Surface RunoffIn hydrologic terms, the runoff that travels overland to the stream channel. Rain that falls on the stream channel is often lumped with this quantity.
It responds slowly, changing little from week to week, and reflects long-term moisture runoff, recharge, and deep percolation, as well as evapotranspiration.
of La Niņa is a phenomenon in the equatorial Pacific Ocean characterized by a negative sea surface temperature departure from normal.Lag1) The measure of the time between the center of mass of precipitation to the center of mass of runoff (on the ...
Threshold RunoffIn hydrologic terms, the runoff in inches from a rain of specified duration that causes a small stream to slightly exceed bankfull. When available, flood stage is used instead of slightly over bankfull.
Basin lag A computed characteristic of a particular river basin, expressed as the time difference between the time-center of mass of rainfall and the time-center of mass of resulting runoff.

What they didn't realise was that runoff from torrential rainfall over the catchments of Sandy and Wolfgang Creeks (over 600mm of rain over the latter), was on its way towards them.
Transition and movement of water around the Earth involving evaporation, transpiration, condensation, precipitation, percolation, runoff, and storage.

of fresh water which empties into salt water (as in Shakespeare's "He shall drink naught but brine; for I'll not show him where the quick freshets are"); (2) in cold climates, the annual spring rise in streambeds which occurs with snowmelt runoff; ...
This is because the rain that falls is soaked up by the crops, trees and grass. ''In April or March you see a lot of water runoff; you see higher flows in the river,'' said Baker. ''But, now you've got the plants intercepting (the rain).
4. Urban flood - pavement which causes rapid runoff (rain can't soak into the ground so it runs downhill) and poor drainage can lead to flooded roadways and underpasses and even become deadly.
Amount of Precipitation
Depth to which the precipitation would cover, in liquid form, a horizontal projection from the Earth's surface, in the absence of infiltration, runoff or evaporation, and if all solid precipitation was melted.
The index depicts prolonged times, as in months or years, of abnormal dryness or wetness. It responds slowly, changing little from week to week, and reflects long-term moisture runoff, recharge, and deep percolation, as well as evapotranspiration.
It should be noted that the NAOI has been strongly positive since the 1980s resulting in unusually wet and mild winter conditions over most of NW Europe and Scandinavia during this period, with concomitant changes in regional runoff.
It was developed to measure lack of moisture over a relatively long period of time and is based on the supply and demand concept of a water balance equation. Included in the equation are amount of evaporation, soil recharge, and runoff and ...
