[email protected] Received 14 February 2020; Accepted 16 January 2021 abstract This research is focused on the land use/land cover (LU/LC) changes impacts on the groundwater table and urbanization trend of Quetta valley for a period of 10 y. The land cover changes are occur- ring locally, regionally, and worldwide, which results in the expansion of urbanization trend and groundwater table depletion. Population growth leads to fast change in land use patterns, which increases the demand for basic needs. Urbanization and climatic impacts on depleting groundwa- ter resources in Quetta need to assess and find a scientific solution using applications of the latest software. This study investigated the land cover changes in three categories, which were barren land, vegetation, built-up area by using maximum likelihood classification (MLC). Water table depletion was defined in five ranges from very low to very high by using the Kriging Method. It is inferred that the built-up area was increased the most in the last 10 y, that is, 2008–2018 as com- pared to other classes.
