Water footprint techniques are extensively used for essential life chores. It also maintains the natural ecosystem. The variations in climatic spell are not only important to investigate the past and current scenarios, but it is also useful to develop the water resource projects. The current study explored the spatial-temporal climatic variation of dry and wet periods (between 1998 and 2010) using the digital image processing technique of ENVI (Environment for Visualizing Images) classics, satellite remote sensing g (SRS), and GIS. The results are organized for the reported period i.e. between 1998 and 2010, showing the change detection of the hydrological effect in the dry and wet years. It shows a significant change in the land use land cover (LULC) of vegetation, water, settlement, and ephemeral rivers followed by 91%, 97.45%, 94.40%, and 62.94 % respectively through the wet year of 2010, in association with the dry period of 1998. For more authentications, the Normalized Difference Vegetative Index (NDVI) image difference of the wet and dry period has also been evaluated, which has shown vegetation in large areas with more water potential in the wet year 2010. The water potential can be used by diverting it to the natural depressions, ditches, and ponds for storage purposes and to increase recharge of groundwater by increasing its quality and quantity. The stored water could be utilized in the drought-prone days for sustainable agriculture activities, to reduce the migra
水足迹技术被广泛用于基本的生活琐事。它还维持了自然生态系统。气候周期的变化不仅对研究过去和现在的情景很重要，而且对开发水资源项目也很有用。利用ENVI (Environment for Visualizing Images)经典数据、卫星遥感(SRS)和GIS等数字图像处理技术，研究了1998—2010年干湿期的时空气候变化特征。结果是根据1998年至2010年的报告时段整理的，显示了干湿年水文效应的变化检测。植被、水体、聚落和短暂河流的土地利用、土地覆被(LULC)在2010年丰水年与1998年干旱年分别变化了91%、97.45%、94.40%和62.94%。为了进一步验证，本文还对干湿期植被指数(NDVI)图像差值进行了评价，结果表明，2010年丰水年大面积植被具有较大的水势。利用水势，可以将其引至天然洼地、沟渠和池塘进行储存，并通过提高其质量和数量来增加地下水的补给。储存的水可以在干旱易发的日子里用于可持续农业活动，以减少迁徙

Gunga deposit is a type of sedimentary exhalative (SEDEX) deposit located in the northwest of Khuzdar Knot within the Kirthar Fold Belt (KFB) in the south-west of Khuzdar city. This deposit is formed during the late Triassic-Jurassic period due to rifting of the Gondwana supercontinent. being hosted with the Anjira Member of Jurassic Shirinab Formation, hosted the Strata bounded barite mineralization in these deposits contact with the siliceous and iron-rich gossan zones. The Baritic zone indicates the complex replacement of silica with the continuous silicification which is followed by massive to brecciated type Barite. Petrographically, barite has a very fine to coarse grain texture, anhedral to euhedral crystal shape, and forms dendritic crystal structure In the Back Scattered Electron (BSE) images, the crystal morphology of Barite exhibits well-developed elongated crystal structures with medium to coarse grain texture. Energy Dispersive X-rays (EDX) graphs indicates the high peaks of Ba, S, and O elements associated with sub-peaks rock-forming mineral elements (Si, Al, Na, K, and Ca) along with sub-peaks of ore-forming mineral elements (Pb, Zn, Fe, P, and Ni).

The construction projects are rising in Pakistan to overcome the flow of traffic on the main road of big cities. Karachi is the metropolitan city of Pakistan facing uncontrolled growth and urbanization, which leads to an increase in the demand for urban transport facilities. The study focuses on the assessment of the environmental impacts of the Tariq Road underpass construction site. The data was collected with the help of community consultation using analytical methods. It includes public chat, site visits, interviews, questioners, and the samples collection of environmental components. The results show that the most common hazards were related to excavation, working practice variation, and personal protective equipment (PPEs). Faulty and unmaintained machinery with the lack of proper barrier producing noise and air pollution.
