pad - inclination, slope


- Posmatrajući šire područje površinskog kopa “Buvač” pad terena je generalno od istoka prema zapadu i od sjevera prema jugu sa postojanjem vododerina sjeverno od eksploatacionog područja, koje su usmjerene u pravcu kopa i koje odvode vodu sa velike slivne površine do granica eksploatacionog područja.
- In the wider area of the open pit "Buvač", terrain slope is generally from east to west and from north to south, with the existence of watersheds to the north of the mining areas, which are directed towards to the mine and the water that drains from a large area to the contour of exploitation area.

Slope
The common notion of the slope of a surface or terrain, t, is the amount of rise (e.g. change in elevation) over run in some direction, usually the direction for which the rise over run is greatest, i.e. the steepest path up or down the surface.

Slope is the measure of steepness or the degree of inclination of a feature relative to the horizontal plane. Gradient, grade, incline and pitch are used interchangably with slope. Slope is typically expressed as a percentage, an angle, or a ratio. The average slope of a terrain feature can conveniently be calculated from contour lines on a topo map. To find the slope of a feature, the horizontal distance (run) as well as the vertical distance (rise) between two points on a line parallel to the feature need to be determined. The slope is obtained by dividing the rise over run. Multiply this ratio by 100 to express slope as a percentage. The slope angle expressed in degrees is found by taking the arctangent of the ratio between rise and run.
