The Hindon River, a tributary of the Yamuna, exemplifies these challenges across 6,232 km2 catchment, encompassing diverse land-use zones from agricultural plains to urban centres like Ghaziabad and Gautam Budh Nagar. This study applies a water balance methodology using open -sources datasets, QGIS, and python -based analytics to assess hydrological trends, groundwater dynamics, evapotranspiration, and land-use impacts in the Hindon catchment. Results reveal a critical water deficit of -342.8 mm/year, driven by overextraction of groundwater, water intensive crops, and high evapotranspiration losses. The paper outlines sectoral vulnerabilities across agriculture, industry, and domestic supply, and proposes a multi-pronged strategy encompassing crop diversification, real-time monitoring, urban water body restoration, and nature – based solutions for building long-term water resilience.

Introduction India faces mounting pressures to reconcile rapid development with sustainable water management. With over 20 major river basins and numerous smaller tributaries, understanding water dynamics at sub – basin levels is essential. The Hindon River catchment, part of the Yamuna basin, originates from Saharanpur district of Uttar Pradesh, flows 350km, draining into the Yamuna River. It traverses mixed land -use zones including high- density urban areas and water – water intensive agricultural zones. The catchment also touches or very small portion of Delhi. The Kali and Krishni rivers are the main tributary of the Hindon river. The location of the Hindon catchment given in Figure 1. Once supporting domestic water needs, the Hindon River is now severely polluted and primarily serves non-potable uses such as livestock washing (Lewis, 2007). With erratic precipitation patterns, intense agricultural pressure, and unregulated groundwater withdrawal assessing water risk in this basin is urgent. 2. Objectives The study pursues the following objectives: 1. Assess systematic water risks in the Hindon catchment 2. Identify region specific vulnerabilities in agriculture, domestic, and industrial sectors. 3. Propose actionable frameworks to enhance long-term water resilience. 3. Methodology The following method adopted to do this assignment given in Figure 2. A simple method used to conduct this study. The details of data sources and framework provided in the following sections. This integrated methodological approach enables a comprehensive understanding of water risks in the Hindon catchment while providing a foundation for identifying targeted interventions to build water resilience in the region. 3.1 Data Collection and Sources This study relies on multiple open sources datasets provided in Table 1.

Catchment Profile 4.1 Administrative Coverage The Hindon catchment spans across 11 districts, predominantly in Uttar Pradesh, and includes key urban-industrial hubs and agriculture belts. The largest shares lie within Saharanpur (1,808 km 2 ) and Muzaffarnagar (1,550 km 2 ) districts. The district wise area distribution provided in Table 2 and shown in Figure 3. Table 2: District comes under the Hindon catchment DISTRICT STATE AREA (Km 2 ) Haridwar Uttarakhand 318.9 Saharanpur Uttar Pradesh 1808.45 Muzaffarnagar Uttar Pradesh 1557.91 Shamli Uttar Pradesh 541.73 Meerut Uttar Pradesh 361.76 Bagpat Uttar Pradesh 721.32 Ghaziabad Uttar Pradesh 524.29 Gautam Budh Nagar Uttar Pradesh 340.45 East Delhi 16.06 Northeast Delhi 8.24 Shahdara Delhi 28.69 4.2 Climate The climate ranges from tropical to temperate with temperature variation up to 3 °C in winter and up to 43 °C in summer and mean annual rainfall of 702 mm subjected to spatial variations (Mayuri Chabukdhara, 2012). The weather averages for the month of October, temperature averages around 33°c and at night it feels like 22°c. In October, Ghaziabad gets on an average 28.11mm of rain[1] and approximately 2 rainy days in the month. The rainfall pattern shown in Figure 4. Humidity is close to 40%. The highest average rainfall occurs during the month of June–September (monsoon period). 4.3 Topography The elevation range of the Hindon catchment range is 180 m to 880m. SRTM 90m digital elevation model (DEM) used for elevation profile and the slope (Figure 5). 4.4 Land-Use The predominant land-use in the Hindon catchment area is primarily agricultural, with a notable presence of built-up urban areas. Specifically, there has been substantial urban development, particularly in the Ghaziabad and Gautam Budh Nagar districts. The land use taken from the Sentinel-2 of the year 2022 (Karra, 2021). The land use classification given in Table 3 and shown in Figure 6. Table 3: Land use classification Classification Area (km 2 ) Water Bodies 14 Forest 278 Agriculture Land 4826 Built up 1079 Bare Ground 31 4.5 Soil The soil[2] in the Hindon catchment mainly loamy in texture and depth of soil is between 100-150cm. The type of soil given in Figure 7. 4.6 Groundwater Groundwater status is the key indicator of water risk of any area. There are 46 administrative blocks are coming where groundwater status assessed. 18 blocks in the catchment are over exploited and 5 are in critical stage. The status of groundwater status shown in Figure 8. The data have been taken from the CGWB groundwater assessment report 2022 and 2024. This shows the water shortage in the future and can impact the local business. 4.7 Evapotranspiration The average evapotranspiration[3] of Hindon catchment is 900mm/year shown in Figure 9. The figure also depicts that evapotranspiration is high in the agriculture areas (green in colour) and evapotranspiration is low in the built-up areas (red colour). 4.8 Water uses India’s water use[4] is heavily dominated by agriculture (85%) due to water intensive crops. Urban and rural water benchmarks are 135 and 55 lpcd respectively, but the actual per capita water footprint is far higher due to water use in food, energy, and goods production. Growing demands, especially in cities and industries, risks severe water scarcity by 2030. This also applicable for Hindon catchment where more than 70% are is agriculture and followed by built up (Ghaziabad, Noida and Saharanpur are major cities etc.,).The district wise annual groundwater extraction ( (Region, 2021) in the Hindon catchment provided in Table 4. Table 4: Annual groundwater extraction (MCM) of the main districts in the Hindon catchment District Irrigation Industrial Domestic Haridwar (UK) -- -- -- Saharanpur (UP) 125786.56 -- 6976.31 Muzaffarnagar (UP) 71932.20 -- 6555.94 Shamli (UP) 41319.36 -- 3009.89 Meerut (UP) 52687.00 -- 8766.22 Bagpat (UP) 35149.16 -- 2.45 Ghaziabad (UP) 37002.24 -- 8060.3 Gautam Budh Nagar (UP) 60634.0 -- 1530.81 5. Water Availability To understand the water risk in the Hindon catchment water availability needs to calculate After the detailed understanding of catchment profile water balance approach have been used to calculate the water balance. It will also help us to understand to connect this with local economy, business and health impacts. This analysis supports decision-makers in planning and implementing timely interventions to mitigate the effects of climate change. 5.1 Water Balance in Hindon Catchment The primary use of water is agriculture which around 70% and sugarcane is main crop. Sugarcane is a water intensive crop. Here water balance approach used to estimate water availability and common factors used to do so. These factors are: soil type, land use, and vegetation cover. For the runoff coefficient, soil and land use parameter used and in the case of Hindon catchment soil is loamy and agriculture is the main land use and this case the runoff coefficient[5] is 0.30. The annual runoff = = Average annual rainfall(mm) X Runoff coefficient =796 X 0.30 =238.8mm The key components of the water balance: Component Value Average Annual Rainfall (mm) 796 Runoff (mm) 238.8 Evapotranspiration (ET) 900 Groundwater Recharge (mm) 200 The water availability is calculated using the formula: Water balance = Precipitation (mm) - Runoff – Evapotranspiration (mm) Water balance = 796 – 238.8 - 900 = -342.8 mm/year The water availability in the Hindon catchment is negative means water deficit that translate annual shortage of approximately 2,136 MCM (342.8 mm/year × 6,232 km²) necessitating continued reliance on groundwater or external supply (e.g., Ganga canal) or indicating that there is not enough water to meet the demands of the catchment. 6. Sectoral Risk Analysis 6.1 Agricultural Risk Crop like sugarcane and paddy demand 1500-2500mm/year and water stress may reduce sugarcane yields by 20-30%. The estimated economic loss is ₹150-200 million annually for sugarcane alone and 70% of the local population is dependent on agriculture. 6.2 Industrial Risk · Industrial zones (e.g. Noida, Ghaziabad) extract large volumes of groundwater · Regulatory restrictions on extraction pose operational risks. · Water scarcity may cause supply disruptions and financial instability. 6.3 Domestic Water Supply · Urban centres increasingly rely in groundwater withdrawn from overexploited blocks. · Public health threats and potential drinking water shortages · Rapidly urbanization nodes like Ghaziabad face growing per capita demand 6.4 Environmental and Ecological Risks · Low lean season baseflow due to groundwater decline · Degradation of riparian ecosystems, loss of urban green spaces. 6.5 Socioeconomic Risks · Risk of out-migration from rural areas to crop failure and employment loss · Water-Related conflicts among competing user sectors (agriculture vs. urban/industrial) 7. Sensitivity Analysis To understand how variations in key parameters affect water availability, a sensitivity analysis (Table 5) was performed by adjusting each parameter while holding others constant: Table 5: Sensitivity analysis Parameter Value Water Balance (mm/year) Change from Base (mm) Change from Base (%) Precipitation (mm) 700 -410 -67.2 -19.60 Precipitation (mm) 750 -375 -32.2 -9.39 Precipitation (mm) 800 -340 2.8 0.82 Precipitation (mm) 850 -305 37.8 11.03 Precipitation (mm) 900 -270 72.8 21.24 Precipitation (mm) 950 -235 107.8 31.45 Precipitation (mm) 1000 -200 142.8 41.66 Runoff Coefficient 0.2 -263.2 79.6 23.22 Runoff Coefficient 0.25 -303 39.8 11.61 Runoff Coefficient 0.3 -342.8 0 0.00 Runoff Coefficient 0.35 -382.6 -39.8 -11.61 Runoff Coefficient 0.4 -422.4 -79.6 -23.22 Evapotranspiration (mm) 800 -242.8 100 29.17 Evapotranspiration (mm) 850 -292.8 50 14.59 Evapotranspiration (mm) 900 -342.8 0 0.00 Evapotranspiration (mm) 950 -392.8 -50 -14.59 Evapotranspiration (mm) 1000 -442.8 -100 -29.17 Based on the sensitivity analysis the key findings are tabulated in Table 6. Table 6: Key findings from sensitivity analysis Precipitation Impact A 19% increase in annual rainfall (to 950 mm) would improve the water balance by 31.4%, but would still leave a significant deficit of -235 mm/year. Evapotranspiration Dominance Changes in evapotranspiration have the most direct impact on water balance. An 11% reduction in ET (to 800 mm) would improve the water balance by 29.2%. Runoff Management Reducing the runoff coefficient from 0.30 to 0.20 through better water harvesting and infiltration would improve the water balance by 11.7%. Breaking Even Point To achieve water balance equilibrium (zero deficit) with current evapotranspiration and runoff coefficient values, the catchment would require annual precipitation of approximately 1,285 mm—a 61% increase from current levels, which is climatologically improbable. Combined Approach Even with optimistic improvements to individual parameters, the catchment would still face a water deficit. This underscores the need for comprehensive interventions targeting multiple aspects of the water cycle. 8. Recommendations · Hydrological monitoring: Real time assessment of river flows and quality · Crop diversification: Switch from water intensive sugarcane to less water demanding crops · STP/ETP Optimization: prevent untreated discharge into the river · Nature based solutions: Wetlands and recharge zone for aquifer recovery · Decision Support Systems: Integrate spatial and temporal data for water management planning. 9. Conclusion The Hindon river basin embodies the broader challenge of water scarcity in India’s rapidly urbanizing and agrarian contexts. The study establishes that business- as-usual practices are unsustainable against a background of declining water availability, overexploited groundwater blocks, and insufficient sectoral use. To enable long-term water resilience, a cross – sectoral, data driven approach forcing on ecological restoration, demand management, and policy integration is critical. increasing demand for water and the impacts of climate change necessitates timely planning and interventions. Restoration and rejuvenation of existing water resources, such as the Hindon River, are essential. The Hindon River holds significant potential to supplement the Ganga water in certain areas. A holistic approach to managing water resources, particularly the Hindon River, is crucial. Declarations Authors Contributions: There is no other author involved in this research.

The Hindon River, a tributary of the Yamuna, exemplifies these challenges across 6,232 km2 catchment, encompassing diverse land-use zones from agricultural plains to urban centres like Ghaziabad and Gautam Budh Nagar. This study applies a water balance methodology using open -sources datasets, QGIS, and python -based analytics to assess hydrological trends, groundwater dynamics, evapotranspiration, and land-use impacts in the Hindon catchment. Results reveal a critical water deficit of -342.8 mm/year, driven by overextraction of groundwater, water intensive crops, and high evapotranspiration losses. The paper outlines sectoral vulnerabilities across agriculture, industry, and domestic supply, and proposes a multi-pronged strategy encompassing crop diversification, real-time monitoring, urban water body restoration, and nature – based solutions for building long-term water resilience.\u003c/p\u003e","manuscriptTitle":"Water Risk Assessment in the Hindon Catchment, India: Challenges and Opportunities for Resilience Building","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-07-28 04:55:58","doi":"10.21203/rs.3.rs-7210895/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"
