Abstract Watershed management is a topic of great concern in the areas coming under shadow zone of rain. Watershed management needs the information about the area covered by water bodies and the relative change in the water body area over the years. This information can be obtained from field survey or by remote sensing. In remote sensing the satellite image is classified into a range of types of land covers by land use and land cover segmentation. The area of segmented water bodies is calculated and validated with the ground truth obtained by field survey. Pondhe village in Pune district is taken into consideration in this particular study. The temporal satellite images of this area are classified into various land covers, and area calculation is carried out. The reduction in water bodies and in the vegetation area is observed over the years by 2.94 % and 27.10 % respectively. The same technique can be used for various regions in future to provide change in areas and to establish a link between geology and image processing.

1 Introduction Every continent has been affected by water scarcity. About 1.2 billion people that are around one-fifth out of total world’s population live in physically water scare areas. Around 500 million people are soon to face the same situation. About 1.6 billion persons that are nearly equal to a 25 % of world’s overall population suffer Mansi Ekbote (✉) ⋅ Ketan Raut ⋅ Yogesh Dandawate Vishwakarma Institute of Information Technology, Pune, India e-mail: [email protected] Ketan Raut e-mail: [email protected] Yogesh Dandawate e-mail: [email protected] © Springer Science+Business Media Singapore 2017 S.C.

from economic water shortage. Economic water storage occurs when countries fail to build the infrastructure which is necessary to take water from rivers and aquifers. In urban India scarceness of water is becoming number one woe at a very fast rate. It has been revealed that out of 32 major cities, 22 have to face water shortage on daily basis. The condition is even worse in rural India. 73.2 % of rural population has undersupply of water. Therefore, watershed management becomes India’s crying need. Planning and development of watersheds needs proper understanding of movement and occurrence of water in surface and subsurface systems and also earth and nutrient fatalities in watershed. The proposed work aims to categorize the land use and land cover. Land cover indicates the physical land type, like open water, forest, or bare land. Land cover can be determined by studying the satellite and aerial imagery. Land cover maps present data to assist managers best comprehend the current landscape. To get an idea about change over time,
