Adaptation planning for India's water sector under climate change: Compendium of Proceedings of the two day National Workshop Singh, Surjeet ed.; Bisht, Deepak Singh ed.; Ghosh, Aindrila ed. This compendium presents a structured documentation of the rich discussions, perspectives and recommendations offered by the moderators and panelists across all sessions. This publication represents a consolidated resource capturing expert deliberations, policy insights and strategic recommendations essential for advancing climate -resilient water sector planning. It is expected to serve as a valuable reference for institutions engaged in research, policy formulation and implementation of climate adaptation measures.

Operations and Principles of Low Level Liquid Scintillation counters and application in Water Resource Managemen : Summer Internship Training Report Ronald BS, Aaron Alexander; Krishan, Gopal Tritium (^3H), a radioactive isotope of hydrogen with a half-life of 12.32 years, serves as a vital tracer for determining the age and recharge characteristics of groundwater. Naturally produced through cosmic ray interactions and historically elevated by mid-20th century nuclear testing, tritium integrates into the hydrological cycle primarily as tritiated water (HTO). This applies tritium dating to groundwater samples from eight locations in Punjab, India, using measured tritium units (TU) and liquid scintillation counting (LSC) to infer residence times. Groundwater samples underwent pre-treatment, electrolytic enrichment, and final tritium activity measurement using an ultra-low-level liquid scintillation spectrometer. Tritium concentrations were converted to TU, and water ages were estimated using the radioactive decay formula, assuming a modern recharge level of 10 TU. The results reveal a spatial gradient in groundwater age. This regional tritium distribution suggests groundwater flow from northwest to southeast and highlights variations in recharge conditions driven by topography, aquifer type, and anthropogenic influences. This report also explains the utility of tritium as a tracer for delineating recharge zones, estimating flow velocities, and guiding sustainable groundwater management. Future integration of stable isotope analysis (δ¹⁸O, δ²H) and hydrogeological modeling is recommended to enhance understanding of recharge sources and aquifer connectivity.

Workshop on Groundwater Rejuvenation As Climate Change Resilience for marginalized and gender sensitive Ganges (GRACERS) Kumar, Sudhir; Pingale, Santosh; Kant, Sumit The main research objective is to identify hot-spots for decentralized and distributed groundwater recharge networks. The specific objectives of the project are: • Identify change in drinking water supply sources for rural, marginalized and women communities • Identify socio-economic stress due to poor groundwater quality and quantity • Identify loss of labor time and education time due to water fetching activities • Identify health issues in consuming polluted water and long-term impacts • Understand limitations in current water diplomacy and potential recommendations to the Government • Identify limitations in groundwater recharge due to centralized water supply schemes • Identify potential private ownership models for rural communities to sustainably manage recharge structures, once key funders exit • Provide knowledge and technical support to government agencies working in the Ganges basin • Provide scientifically validated management plans for up-scaling distributed groundwater recharge networks.

A Brief Report on NHP sponsored Five-days Online Training Course on HYDROLOGICAL MODELING USING SOIL AND WATER ASSESSMENT TOOL (SWAT): THEORY AND HANDS-ON (August 22-26, 2022 at NIH, Roorkee) Nema, M. K.; Singh, Vishal Water is a vital natural resource. Hydrological modelling is an essential aspect of any development project for planning, designing, executing, and managing water resources efficiently. A hydrologic model simplifies a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models. SWAT is widely used in assessing soil erosion prevention and control, non-point source pollution control and regional management in watersheds. This training course was designed to impart and transfer the working knowledge of using a semi-distributed hydrological model called the Soil & Water Assessment Tool (SWAT), which is a small watershed to river basin scale model used to simulate the quality and quantity of surface and ground water and predict the environmental impact of land use, land management practices, and climate change.
