Kurzbeschreibung (Abstract)

The water resources that supply most of the megacities in the world are\backslashnunder increased pressure because of land transformation, population\backslashngrowth, rapid urbanization, and climate-change impacts. Dhaka, in\backslashnBangladesh, is one of the largest of 22 growing megacities in the world,\backslashnand it depends on mainly groundwater for all kinds of water needs. The\backslashnregional groundwater-flow model MODFLOW-2005 was used to simulate the\backslashninteraction between aquifers and rivers in steady-state and transient\backslashnconditions during the period 1981-2013, to assess the impact of\backslashndevelopment and climate change on the regional groundwater resources.\backslashnDetailed hydro-stratigraphic units are described according to 150\backslashnlithology logs, and a three-dimensional model of the upper 400 m of the\backslashnGreater Dhaka area was constructed. The results explain how the total\backslashnabstraction (2.9 million m(3)/d) in the Dhaka megacity, which has caused\backslashnregional cones of depression, is balanced by recharge and induced river\backslashnleakage. The simulated outcome shows the general trend of groundwater\backslashnflow in the sedimentary Holocene aquifers under a variety of\backslashnhydrogeological conditions, which will assist in the future development\backslashnof a rational and sustainable management approach.
