This paper presents the findings of the research conducted in Morogoro Municipality, central Tanzania. The main objective of the research was to assess the climate change impacts on water resources, taking the Mindu Dam as the case study. The study methodology involved collection, processing and analysis of both primary and secondary data. Data collection involved acquisition of Dam water level data, climate data, and Landsat 8 satellite imagery. Research findings showed that the maximum air temperature increased at a rate of 0.045% on a span of 30 years, while rainfall has been decreasing with time. Also there has been a decreasing trend of water level in the Mindu Dam such that the coefficient of determination (R2) appeared to be very small (0.95%). The area also has witnessed an increasing trend in wind speed (R2 = 63.4%) for the period 2014 to 2019. The results showed coefficient of determination (R2) for water production/supply of only 1.58%, while for water demand the coefficient of determination was R2 = 77.13%. Findings on the changes in surface area covered by the Mindu Dam reservoir due to climate change impacts showed that for the period of 19 years, the Mindu Dam reservoir surface area decreased by 0.57%.

Aswan High Dam

The Aswan High Dam Reservoir management system was developed to simulate dam operation under varying boundary conditions taking as example climate change and Millennium Dam construction, and analyze the optimal operation rules of the reservoir taking into account a large number of objectives, including hydropower production and water supply for irrigation purposes. The developed system runs on Windows platforms and comprises three basic modules: a user-friendly graphical interface managing all graphic features, a computational engine where all the algorithms are implemented, and a database and files module managing hydrological and operational data. The developed model was calibrated. The future hydrologic scenarios developed have been used to assess the expected impacts of potential climate change (baseline and three periods with two global emission scenarios) and the Millennium Dam. The new operation rules were used for scenarios analysis. It was concluded that overall applying the new operation rules will decrease the percentage of occurrence of minimum water levels. Also, the Millennium Dam will increase the percentage of occurrence of minimum water levels. Finally, the period III (2070–2099) for the two global emission scenarios is very critical for the dam operation.
