Gradient is the slope of the stream and is measured by the difference in elevation between two points on a stream divided by the distance between the two points that the water actually flows. GRADIENT How to calculate the gradient using a topological map RM ACCOUNTS ED ram@2011 reserved 2. Gradient wind, wind that accounts for air flow along a curved trajectory. Gradient CSEC Geography 1. Gradient is usually expressed in feet per mile of meters per kilometer. Density Gradient. A river with a high gradient loses height quickly and is typically fast flowing and youthful. | Meaning, pronunciation, translations and examples gradient definition: 1. how steep a slope is: 2. how steep a slope is: 3. a measure of how steep a slope is, oftenâ¦. Learn more. To work out Gradient, use the following formula: Gradient = VI Vertical Height HE Horizontal Equivalent VI = Highest height - Lowest height - always in metres The gradient of a river is a measure of how steeply it loses height. Gradient definition: A gradient is a slope, or the degree to which the ground slopes. The phrase RISE OVER THE RUN is the "shorthand" of the formula. Alluvium: rock particles (clay, silt, sand and gravel) deposited by a river. Definition: The change in density in an urban area from the center to the periphery. Gradient This is the STEEPNESS of a slope, and is represented as a ratio eg 1 : 50, 1 : 500 Remember: THE SMALLER THE NUMBER, THE STEEPER THE SLOPE. Pressure Gradient: Pressure gradient can be defined as the rate of change of barometric pressure at a particular time in a particular region. 7. The gradient (or gradient vector field) of a scalar function f(x 1, x 2, x 3, ..., x n) is denoted âf or â â f where â denotes the vector differential operator, del.The notation grad f is also commonly used to represent the gradient. Formula to be applied ⢠Gradient is an expression of the change in elevation over the distance covered along the surface. The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal.It is a special case of the slope, where zero indicates horizontality.A larger number indicates higher or steeper degree of "tilt". The gradient of f is defined as the unique vector field whose dot product with any vector v at each point x is the directional derivative of f along v. Example: Model. Application:Very Important because Density Gradient affects urban areas. It is an extension of the concept of geostrophic windâi.e., the wind assumed to move along straight and parallel isobars (lines of equal pressure). Work out the gradient of the slope if Point A has a height of 500 metres, Point B has a height of 400 metres, the distance between the two points is 6cm, and the scale of the map is 1:50,000. A river with a very gentle gradient loses very little height and is typically a slow flowing mature river. Attrition: The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size.. Base Level: the mouth of the river and the point where the gradient becomes zero. Abrasion: the pebbles being transported wear away the bed and banks of the river channel. Pressure Melting Point : As per geography terms, pressure melting point is the temperature at which ice melts when pressure is applied to it. GCSE Rivers Glossary.
