Abstract

Numerous studies have focused on analyzing changes in reservoir storage using inflow and outflow ratios and related models. The present work endorsed a new image-driven hydrological components-based approach for water storage inconsistency and susceptibility study using water presence frequency (WPF) and the Rule-based decision tree (RBDT). This study would be an effective means for monitoring inflow and outflow in infrastructure-scarce settings.

The findings indicate that (1) There is a significant seasonal fluctuation in water cover area, with a seasonal coverage of 19 km² and water depth closely correlating with rainfall, (2) The area of inconsistent water storage increased from 7% in the 1st phase to 18% in the 3rd phase mainly in the reservoir fringe area, (3) In last 30 years, the water storage area during pre-monsoon and post-monsoon seasons has been identified as 16 km² and 10 km² respectively, (4) From phase-1 to phase-3, the area under eco-hydrological stress during the post-monsoon season increased from 17% to 71%, (5) The proportion of areas under very high and high susceptibility was increased from 20% to 48% in between phase 1 to 3. These trends highlight the growing uncertainty in water supply, ecological habitat, and related ecosystem goods and services. This finding is an early caution to avoid economic and ecological risk due to hydrological failure caused chiefly by anthropogenic factors. This research provides valuable insights for long-term water resource planning and assessment. The approach is also a state-of-arts in infrastructure-scarce conditions and could be reproduced in other such regions.

期刊介绍： Environmental Development provides a future oriented, pro-active, authoritative source of information and learning for researchers, postgraduate students, policymakers, and managers, and bridges the gap between fundamental research and the application in management and policy practices. It stimulates the exchange and coupling of traditional scientific knowledge on the environment, with the experiential knowledge among decision makers and other stakeholders and also connects natural sciences and social and behavioral sciences. Environmental Development includes and promotes scientific work from the non-western world, and also strengthens the collaboration between the developed and developing world. Further it links environmental research to broader issues of economic and social-cultural developments, and is intended to shorten the delays between research and publication, while ensuring thorough peer review. Environmental Development also creates a forum for transnational communication, discussion and global action. Environmental Development is open to a broad range of disciplines and authors. The journal welcomes, in particular, contributions from a younger generation of researchers, and papers expanding the frontiers of environmental sciences, pointing at new directions and innovative answers. All submissions to Environmental Development are reviewed using the general criteria of quality, originality, precision, importance of topic and insights, clarity of exposition, which are in keeping with the journal''s aims and scope.
