E-raamat: Climate Variability and Human Interference: Hydrologic Transformation of the South Koel River Basin and Linkages to the Downstream Deltaic System, Eastern India

Introduction.- Outlines the importance of studying hydrologic impacts of
climate variability and human activity, setting the stage with an overview of
global and regional concerns.- State-of-the art-review - presents a
comprehensive global review on the general topic of the proposed book that
should be closed by identification of the research gap and the scope of the
current study to fill all or part of the identified research gap.- Study Area
and Research Methodology Describes the geographical, climatic, and
socio-economic context of the South Koel River Basin. Presents data sources,
model framework (SWAT), and analytical tools used.- Step Change and Trend
Analysis of Rainfall and Runoff Examines historical changes in rainfall and
runoff using Mann-Kendall trend test and Pettitt's test, identifying
significant shifts over time.- Quantifying Climate vs. Human Influence on
Runoff Uses simulation-based methods to separate and compare the impacts of
climate variability and land use changes on runoff.- Runoff Sensitivity to
LULC Change Evaluates how forest degradation and agricultural expansion
affect runoff using land cover sensitivity scenarios and percentage change
models.- Major Findings and Implications Summarizes key findings, providing
scientific insights into runoff alteration mechanisms and basin-specific
vulnerabilities.- Policy Recommendations and Future Research Directions
Suggests actionable strategies for integrated water resource management and
identifies gaps for further research.
