This study attributes the greatest causes of delays to increasing the count of trains faster than the base flow, new trains entering the network after the subject train, and increasing the count of trains slower than the base flow.
Base flow is often seen as the minimum supply of water on which people can safely rely.

Topics include models for jurisdictional identification, expert system-based imagery, mapping of specific vegetation, spectral angle mapping, long-range supply and demand, reforestation, stream flow simulation and base flow separation, variations in nutrients and chemicals, erosion, and assessment of risk, human impact, and pollution.
If that happens, you lose the base flow [the portion of water derived from underground sources] for streams, and you lose the wetlands fed by springs.
Determine pattern of spring runoff-summer base flow of comparison streams and superimpose the pattern of spring runoff-summer base flow decline from non-impacted comparison streams on the Muddy Creek hydrograph;
And, since base flow is synonymous with stream health and water quality, it was clear that clean water is directly linked to the canopy cover provided by trees.
Base flow is the groundwater that seeps through walls of an open channel or ditch.
However, if the wings are to be applied from above - as is usually the case - the wing extruder must be placed underneath and the compound fed through openings in the base flow channel (figure 5).
