'''Stream gradient''' is the ratio of drop in a [[stream]] per unit distance, usually expressed as [[Foot (unit of length)|feet]] per [[mile]] or [[meter]]s per [[kilometer]]. A high gradient indicates a steep slope and rapid [[volumetric flow rate|flow]] of [[water]] (ie. more ability to erode); whereas a low gradient indicates a more nearly level [[stream bed]] and sluggishly moving water, that may be able to carry only small amounts of very fine [[sediment]]. High gradient streams tend to have steep, narrow V-shaped [[valley]]s, and are referred to as young streams. Low gradient streams have wider and less rugged [[valley]]s, with a tendency for the stream to [[meander]]. |

The '''Dino Thunder Power Rangers''' (canonically referred to as the '''Dino Rangers''') are [[fictional characters]] and [[heroes]] in the [[Power Rangers]] universe, appearing in the [[television series]] ''[[Power Rangers: Dino Thunder]]''. |
|||
A stream that flows upon a uniformly [[erosion|erodible]] substrate will tend to have a steep gradient near its source, and a low gradient nearing zero as it reaches its [[base level]]. Of course, a uniform substrate would be rare in nature; hard layers of [[rock (geology)|rock]] along the way may establish a temporary base level, followed by a high gradient, or even a [[waterfall]], as softer materials are encountered below the hard layer. Human [[dam]]s, [[glaciation]], changes in [[sea level]] and many other factors can also change the "normal" gradient pattern. |

On [[topographic map]]s, stream gradient can be easily approximated if the scale of the map and the contour intervals are known. Contour lines form a V-shape on the map, pointed upstream. By counting the number of lines that cross a stream bed within a measured distance, and converting this to the actual measurements of the land surface, will determine the actual gradient. For example, if one measures a scale mile along the stream length, and counts three contour lines crossed on a map with ten-foot contours, the gradient is approximately 30 feet per mile, a fairly steep gradient. |

The Dino Rangers got their powers from special [[Magical Items and Weapons in Power Rangers#Dino Gems|Dino Gems]] of their respective colours, which gave them superhuman abilities and allowed them to transform into Power Rangers. They used their abilities to battle the evil mastermind [[Mesogog]]. |

'''Tommy Oliver''', played by Jason David Frank, is the mentor of the Ranger team and also the Black Dino Ranger. His Dino Gem has the power of invisibility, but he rarely uses this power. He was originally the Green Power Ranger, then the White Power Ranger, Zeo Ranger V — Red, and then the first Red Turbo Ranger. Jason David Frank first reprised his role as Tommy in the ''[[Power Rangers: Wild Force]]'' episode [[Forever Red]] along with nearly every other former [[Red Ranger]]. |

Stream gradient is the ratio of drop in a stream per unit distance, usually expressed as feet per mile or meters per kilometer. A high gradient indicates a steep slope and rapid flow of water (ie. more ability to erode); whereas a low gradient indicates a more nearly level stream bed and sluggishly moving water, that may be able to carry only small amounts of very fine sediment. High gradient streams tend to have steep, narrow V-shaped valleys, and are referred to as young streams. Low gradient streams have wider and less rugged valleys, with a tendency for the stream to meander.
A stream that flows upon a uniformly erodible substrate will tend to have a steep gradient near its source, and a low gradient nearing zero as it reaches its base level. Of course, a uniform substrate would be rare in nature; hard layers of rock along the way may establish a temporary base level, followed by a high gradient, or even a waterfall, as softer materials are encountered below the hard layer. Human dams, glaciation, changes in sea level and many other factors can also change the "normal" gradient pattern.
On topographic maps, stream gradient can be easily approximated if the scale of the map and the contour intervals are known. Contour lines form a V-shape on the map, pointed upstream. By counting the number of lines that cross a stream bed within a measured distance, and converting this to the actual measurements of the land surface, will determine the actual gradient. For example, if one measures a scale mile along the stream length, and counts three contour lines crossed on a map with ten-foot contours, the gradient is approximately 30 feet per mile, a fairly steep gradient.
