This segmentation is rather useful in the identification of clusters by incorporating the spatial and spectral characteristics that distinguish builtup and non-built-up regions. Training samples were obtained from satellite imagery and aerial images collected in 2019 with equal distribution of samples in the classification. Object-based classification has major benefits over pixel-based techniques in using spatial context and minimizing misclassification in urban areas. …

Water Quality Standards Assessment, Using Epanet Modeling– Prishtina Case – Oxidation-Reduction Of Manganese On Dw Network, Sokol Xhafa

UBT International Conference

Thermal stratification and water movement in reservoirs are key natural processes. While most effects of this movement are beneficial, such as increased oxygen levels, the presence of manganese (Mn) poses a challenge. During autumn, water circulation causes manganese to shift from its solid Mn(4+) form to the dissolved Mn(2+) form, preventing sedimentation and leading to issues in water treatment and distribution networks. This report focuses on these challenges at the Badovc Reservoir, near Prishtina, Kosovo. Built in 1965, Badovc is one of the oldest reservoirs in the country. Manganese, while usually an aesthetic issue that can cause "black water," can …
