 NodeWorks - Encyclopedia: RUNOFF
RUNOFF is a direct predecessor of the runoff document formatting program of Multics, which in turn was the ancestor of the roff and nroff document formatting programs of Unix, and their descendants.
RUNOFF was the first computer text formatting program to see significant use.
RUNOFF had support for pagination and headers, as well as text justification.

 Treating and Recycling Irrigation Runoff
Obviously, the less runoff you have to deal with, the less of a problem it creates.
Since up to the first 2 inches of storm runoff must be collected reservoir capacity should be designed on the basis of predict-able storm events.
Common sense is often all that is required to implement cultural inputs that will reduce runoff, as well as improve water quality.

 Purdue AGEN 526: Storm Runoff Prediction
Since hydrographs of previous storm events are seldom available for small watersheds, estimates of peak rates and/or volume must be made using computational models rather than from statistical analyses of past records.
This can be illustrated by a hydrograph with a steady rainfall input:
The runoff coefficient, C, is dependent upon physical characteristics of the watershed, e.g.

 Instant Runoff Voting
Instant runoff voting was invented by an American, W. Ware, a Professor at the Massachusetts Institute of Technology, around 1870.
Condorcet - this system measures which candidate has the broadest support.
Instant Runoff Voting is a system that guarantees the winning candidate has a majority of the votes (instead of a plurality) and eliminates the "wasted vote syndrome" caused by third party candidates.

 Predicting Runoff from Rain Events I
For the next few classes, we will be looking at methods used to generate runoff hydrographs.
Unfortunately, you can't "feel" your way to an engineering design.
The following is a list of some of the factors which you must consider when estimating runoff.
http://grapevine.abe.msstate.edu/classes/abe4312/2001e/lec3/runoff_1.html

  
 Rainfall runoff
The depth to which a watershed (drainage area) would be covered if all of the runoff for a given period of time were uniformly distributed over it.
Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion.
Drainage ditches to carry stormwater runoff to storage ponds are often built to hold runoff and collect excess sediment in order to keep it out of streams.
http://ga.water.usgs.gov/edu/runoff.html

  
 Reducing Erosion and Runoff
Be aware that changing soil level near well-established trees can seriously damage their root systems.
There are many ways to reduce erosion and runoff, as well as control the direction of drainage.
Erosion and runoff in the home landscape also create unsightly bare areas and deposit mud and dust on driveways and walkways that is then tracked into the house.

 Measure H: Runoff Elections Charter Amendment - Alameda County, CA
Measure H will fix the resulting problems by moving the runoff election to early February and reducing the threshold required to win outright to 40%. 
Under the current system, Berkeley must print and mail ballots for a runoff election only a few days after the general election + before final election results are known.
By moving the runoff to February and reducing the threshold to win to 40%, Measure H will save taxpayer dollars by eliminating preparations for unnecessary runoff elections and by reducing the total number of runoffs.

 Is Highway Runoff A Serious Problem?
Infiltration basins, on the other hand, can operate effectively from 5 to 10 years before requiring deep tilling.
Treatment of runoff, if needed, should be a function of this water quality evaluation.
Highway runoff that soaks into soil with or without the presence of any type of vegetation, channel, or basin is usually harmless to the environment.

 Instant Runoff Voting Remains Too New for Ferndale Voters - 06/21/04
Simon's Challenge at MSU Is to Continue McPherson's Vision
The sample runoff ballot posted on the Internet, however, conjures up nightmarish memories of Florida’s 2000 presidential election where ballots were counted and recounted, and “chad” became part of the national vocabulary.
Ferndale should see how they work out the glitches before investing in what could be a turnoff for the voters they want to turn out for the city elections.

 Runoff voting - Wikipedia, the free encyclopedia
A simplified model of a two round system is the supplementary vote.
A two-round runoff voting system, in practice, may work as a system of primary elections in countries where there are two major partisan blocks, by choosing for the second round of election a candidate in each block.
Assuming each voter voted for his preferred city (for a more sophisticated approach, see below), the first ballot results would be as follows:

 Instant-runoff voting - Wikipedia, the free encyclopedia
This is considered a weakness by the advocates of a more deliberative democracy, who point to the French system of presidential election where such between-round dealings are heavily exploited and useful (they say) to draw together a very factionalized electorate.
Instant Runoff Voting as an ideal does not explicitly define how to handle special cases such as ties and different rules can be considered.
Unlike runoff voting, however, there are no chances to deal in between rounds, change voters' minds, or gain support of the other candidates.

 Runoff from the Researcher Perspective (2-D processes)
Check out the on-line dissertation on InterWET for more information behind the theory and techniques used to make this calculator.
In InterWET, the runoff from the researcher perspective gives a two dimensional view or process level view of runoff using the SCS-CN Method.
Notice how the runoff becomes a higher percent of the rainfall when the rainfall values go up.

 Stormwater Agricultural Runoff
The third function of an RFBS is control of dissolved phosphorus (P) in surface runoff or shallow groundwater.
Point sources, such as municipal sewer systems, usually enter the water body via pipes, and it is comparatively easy to collect that water and run it through a treatment system before releasing it into the environment.
Often practices aimed at controlling one aspect of agricultural runoff are also effective at reducing other components because of the interrelationships between runoff volume, erosion, transport, dissolution, and delivery.

 Surface Water Runoff: Algorithm (Background Mathematics
This is represented through its relationship to the value of the runoff curve number (CN), which has a value from 0 to 100.
Soils are extremely important in determining the runoff curve number, since these values can vary widely.
So a parking lot would have a high value, around 99, whereas a field with lots of grass and healthy soil would have a much lower value (around 35).

 ARS Publication request: A Simple Method to Predict Dissolved Phosphorus in Runoff from Surface Applied Manures
One weakness of such models is their poor simulation of the release of P from surface applied manures to runoff.
We developed an approach to predict dissolved P release from manures based on trends of P release from manures to water with increasing water:manure ratio.
Computer simulation models are a rapid, inexpensive way to identify areas in an agricultural watershed with a high potential for P loss.
