Topography-based hydrological modelling in the Elbe drainage basin
The paper is focused on the applicability assessment of two models for large scale hydrological simulation, both of which are based on the topographic index concept.
The configuration of a surface, including its relief and the position of its natural and man-made features.

[cartography] The study and mapping of land surfaces, including relief (relative positions and elevations) and the position of natural and constructed features.
is the study of Earth's surface features or those of other planets, moons, and asteroids.

topography Loads a new raster or constant value to use as elevation (z values) for the current surface.
The configuration of the Earth's surface including relief and the position of natural features. Contours indicating lines of equal surface elevation are used to illustrate on a map.

Topography is often mistakenly used as an alternative to relief but the two are somewhat different. Topography refers to the description or representation on a map of all features in a given area, both natural and man made.
The image on the left (above) is a false color radar image, while the image on the right shows data made while AirSar was being flown in interferometric mode.
The topography - the physical surface of the earth.
The Geoid - the level surface (also a physical reality).
The Ellipsoid - the mathematical surface for computations.
Other functions include illumination techniques to enhance display of elevation or relief, viewshed modeling to determine what areas can be seen from a specific point for appraising visual impacts, ...
While the topography is becoming more apparent, it is still better to display continuous data with a stretched, rather than classified, symbology.

While the term topography describes the precise physical location and shape of geographical objects, the term topology is more concerned with the logical relationships between the position of those objects.

We may need to visualize the topography of urban areas in three dimensions to plan for a night on the town or to respond to an emergency. We may need a 3d visualization of a historic urban scene to investigate a situation that doesn't exist anymore.
Here are some maps of Afghanistan showing the of the country. Good overlay material for Afghanistan is in short supply. The best I have found are Russian 1:50,000 and 1:200,000 topo maps, but they are not cheap.
