Image of Odd radio circle ORC J2103-6200 by the MeerKAT telescope superimposed on an optical image from the Dark Energy Survey (2022) [1] [2]. In astronomy, an odd radio circle (ORC) is a very large (over 50 thousand times the diameter of our Milky Way ~ 3 million light years) unexplained astronomical object that, at radio wavelengths, is highly circular and brighter along its edges.

The Landfill Fire merged with the Freeway Fire at 3:30 a.m. PDT on November 16, 2008. At approximately 7:00 a.m. PDT the two fires were officially renamed the Triangle Complex Fire. Around 12:45 p.m. the Triangle Complex Fire had been renamed once again to the Freeway Complex Fire still using the OCFA incident number CA-ORC-08075221. [3]
Fertilizer use on residential lawns, parks and golf courses is a measurable source of nitrates and phosphorus in urban runoff when fertilizer is improperly applied or when turf is over-fertilized. [3] [5] Eroding soils or poorly maintained construction sites can often lead to increased sedimentation in runoff. Sedimentation often settles to the ...

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).It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
A typical freeway-over SPUI. This example, near Orlando, has since been demolished. California State Route 87 at Taylor Street, a freeway-under SPUI. A SPUI is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road.
Q = discharge of inlet (ft 3 /s) W = width of the chute or inlet (ft) H = depth of flow over the crest (or floor) of the inlet (ft) H e = specific energy head in reference to the crest of the inlet, or the head over the crest of the inlet (ft) v a = mean velocity of approach at which the depth H is measured (ft/s) g = 32.16 ft/s 2
