This paper presents the results of a modeling study on the potential effects of different scenarios of managed aquifer recharge in the Coastal Plain of Dar es Salaam (Tanzania). The city of Dar es Salaam is one of the fastest-growing cities in sub-Saharan Africa, with more than 4 million of inhabitants and a population growth rate of about 8 per cent per year. The city faces periodic water shortages, and in the last ten years, the excessive withdrawals of groundwater have accelerated the rate of seawater intrusion in the coastal plain. A steady-state groundwater model has been set up by the MODFLOW code, and calibrated by the UCODE code for inverse modeling. The purpose was to produce a reasonable accurate model of the groundwater flow system of the Dar es Salaam Coastal Plain, based on available data, and to simulate different scenarios of managed aquifer recharge, aimed to increase the amount of infiltration of precipitations in the subsoil.

Abstract
This paper presents the results of a modeling study on the potential effects of different scenarios of managed aquifer recharge in the Coastal Plain of Dar es Salaam (Tanzania). The city of Dar es Salaam is one of the fastest-growing cities in sub-Saharan Africa, with more than 4 million of inhabitants and a population growth rate of about 8 per cent per year. The city faces periodic water shortages, and in the last ten years, the excessive withdrawals of groundwater have accelerated the rate of seawater intrusion in the coastal plain. A steady-state groundwater model has been set up by the MODFLOW code, and calibrated by the UCODE code for inverse modeling. The purpose was to produce a reasonable accurate model of the groundwater flow system of the Dar es Salaam Coastal Plain, based on available data, and to simulate different scenarios of managed aquifer recharge, aimed to increase the amount of infiltration of precipitations in the subsoil.File | Dimensione | Formato | |
