Anthropogenic processes:

Man and his activities – anthropogenic processes – contribute to relief formation:

• quarries and mines

• roads

• settlements and their ruins

• river and sea canals

People and their activities:

---speed up weathering by pollutants releasing into the atmosphere

---cause soil erosion and silting-up of dams by deforestation

---activate artificial earthquakes, etc.

Dr Potdar , very interesting question . The impact human intervention on both landforms and processes are huge , which comprise of moats , city mounds, canals, reservoirs, depressions, banks along roads, pits , ponds, brounds, spoil heaps, terracing , ridge , furrow, cuttings , sunken lanes, embankments, dikes, mounds, craters etc ...Here are some examples of case studies . PDFs are also enclosed for your further reading please:

This paper identifies various coastal landforms and anthropogenic activities in relation to ecosystem degradation and stability on the southwestern Nigeria coastline. It uses topographical base maps, Landsat ETM+ magery, field survey, and ancillary data to assess and map the various geomorphic units and ecosystem degradation in the study area. Identification of various coastal landforms was carried out using image interpretation elements, especially the tonal and shape differentiation. Some geomorphic units identified include islands, lagoons, peninsulas, coastal plains and beaches, pools and mud coastline. Recent morphological dynamics catalysed by sea-level rise have led to the decrease of some coastal landform units. Sand  mining, urbanization, wetland reclamation, and industrialization were identified as causing perturbation of the ecosystem. For sustainable development of the fragile morphological systems of the study area, anthropogenic activities resulting in biodiversity loss and landform alterations should be controlled, while oil exploration activities around the mud coast should adopt best practices.(Source :Deltas: Landforms, Ecosystems and Human Activities

Hope you like them.

thank you so much i will go through it 

Dear Dr Potdar ,

Well I have very little understanding , except in rural/suburbs places there are dumping yards . Scary, compost/landfills has a huge toll .

Easy to detect in all types of environments, just to add to the above:

Easy to detect, anything that leads to flash flooding during heavy downpours is due to man-made structures: canals, lowering water table, straightening of river channels, "control" structures along rivers, blocking the rain water from entering the ground, etc

All these form special types of landforms that are traps, sure to cause disasters in the future.

Landslides by deforestation over slopes and undercutting slopes.

Clear-cutting of trees except near highways where tourists pass. Previously forest areas that are becoming deserts - supposed to be re-planted, what a joke!

Old mining sites where no reclamation was required at the time. The list includes uranium mining sites that are still polluting the surroundings.

Chemical dumping sites by the thousands. Nobody could clean them and the pollution will spread into the surroundings sure to become Dead Zones for living things.

I request our colleagues to please take stock of ecological implications of these anthropogenic landforms. 

A real hard question!!!! 

Men made structures generally exhibit structural symmetry ( shape)  but, many a time natural landforms are also bear symmetry. .so, what are the additional criteria??? May be size? Natural landforms are much larger then those made by men?
