Sustainable management of Uluova micro basin groundwater

In the period we live in and in the near future, the rapidly increasing industrialization and population, together with the negative effects of climate change and global warming, will have a serious negative impact on groundwater resources. These negative effects can be minimized by using models capable of watershed-scale water management and planning that center the relationship between water, energy, and the ecosystem. Hydroeconomic optimization models made for this purpose are used in water planning and management to simulate different management situations and to help decision-makers learn about system operations. Hydrological and economic data are used together in hydroeconomic models. The ULUHEM model was developed as a hydroeconomic optimization model representing the water supply infrastructure covering Uluova and Elazig city centers. Optimum water management strategies under different management and climatic conditions were investigated with ULUHEM. In the network flow representation of the ULUHEM model, the urban water demand of the city center of Elazig in 2040 and the water demand and famine costs of the Uluova agricultural lands were calculated using monthly surface and groundwater hydrology over a 20-year period between 1991 and 2011. The effects of ending long-term groundwater overdraft in the Uluova micro-basin have been evaluated with various management scenarios. For agricultural water demand, the work has been expanded under different overdraft situations, under different scenarios such as "no overdraft" and "no groundwater pumping", as well as overdraft and basic water operations. In addition, the effects of climate change under overdraft basic water operation and arid and wet climate scenarios were examined under different scenarios. As a result, in overdraft scenarios, while famine costs are more concentrated on agricultural users, urban users are not affected much. The "no overdraft" and "no underground pumping" scenarios further increase the costs of agricultural famine occurring in the base case. In scenarios made under the influence of climate change, on the other hand, as the severity of drought increased, water scarcity and famine costs increased. In wet climate scenarios, on the other hand, as the severity of precipitation increased, water scarcity and scarcity costs decreased. It has been observed that an appropriately powered Solar Power Plant to be built in the region eliminates water scarcity and scarcity costs that occur in overdraft basic water operations.
