Completed Studies
Water Budgeting and Economical Assessment of Irrigation Water through Drop Fertigation in Rice – Rice – Pulse Cropping System
Institution: Tamil Nadu Agricultural University (TNAU), Thoothhukudi
Overview: The study explains the water crisis in Tamil Nadu, India. Despite having only 2.5% of the country's water resources, Tamil Nadu faces high demand due to its population and economic growth. Agriculture, heavily reliant on monsoon rains, consumes the majority of the state's water. Rice, a major crop, requires significant water. This research study proposes drip irrigation as a potential solution. The study aims to compare conventional flood irrigation to drip irrigation in terms of rice yield and growth within a rice-rice-pulse cropping system. The project will also explore how drip irrigation affects soil moisture and the potential benefits of border cropping (planting fast-growing green manure crops) on water needs. Ultimately, the goal is to develop a water budgeting model for this cropping system using drip irrigation and train rice farmers in southern Tamil Nadu.
Developing IoT Based Smart Water Management to enhance the water and crop productivity
Institution: Tamil Nadu Agricultural University (TNAU), Madurai
Overview: This project focuses on optimizing water usage in agriculture through precision irrigation using IoT. It aims to leverage sensor technology for real-time soil moisture assessment, develop software for data management, and evaluate the water-saving potential of smart irrigation systems. Additionally, it investigates the impact of IoT-based irrigation on crop yield to promote sustainable and efficient farming practices.
Documentation of local use of micro watersheds in Tamiraparani Basin, Tirunelveli District
Institution: Care Earth Trust (CET), Chennai
Overview: The study investigates the impact on water, assesses irrigation and drinking water access, identifies implementation challenges in existing programs, and evaluates issues faced by marginal and landless farmers in the hydrologically significant Tamirabarani River Basin, aiming to inform policy guidelines for the region’s welfare.
Modalities suggested for Implementing the project of Water Security at village level at Trichy and Tiruppur
Institution: Centre for Water Resources (CWR), Anna University, Chennai
Overview: This study investigates water security in Tiruchirappalli and Tiruppur Districts of Tamil Nadu, focusing on household and agricultural aspects. Objectives include creating a socio-economic profile for selected blocks and assessing domestic and agricultural water security to address regional disparities and promote balanced development.
Modalities suggested for Implementing the project of Water Security at village level at Dharmapuri and Krishnagiri
Institution: Centre for Water Resources (CWR), Anna University, Chennai
Overview: The State of Tamil Nadu initiated the “State Balanced Growth Fund (SBGF)” to address regional disparities. A study identified 105 backward blocks, focusing on water scarcity as a key issue. Examining 3 highly imbalanced blocks, 300 households across 15 villages were surveyed. The study aims to provide water security insights to aid the State Planning Commission’s project, focusing on socio-economic profiles, and domestic, and agricultural water security.
Removal of Turbidity and COD from Oorani water in Dindivanam Taluk, Tamil Nadu by natural coagulants
Institution: Presidency College, Chennai
Overview: This project aims to assess turbidity through analytical methods and evaluate chemical parameters in water. It focuses on the efficiency of natural coagulants for specific contaminants, maintaining water quality, and reducing chemical oxygen demand. The study explores sludge reuse and aims for safe drinking water with turbidity below 5 NTU for Thenkalavoy Oorani in Tindivanam Taluk.
Cadastral level information system on Minor Irrigation tanks in 1:5000 scale using Remote Sensing and GIS in Namakkal district
Institution: Agricultural Engineering Department (AED), Chennai
Overview: This study aims to assess and enhance the management of water resources in Namakkal district. Objectives include creating an information system for Minor Irrigation tanks at cadastral levels, analyzing catchment area properties, evaluating storage capacity, and studying ayacut area characteristics and cropping patterns for effective water resource utilization.
Improving Land and Water Productivity of a Watershed in Palar Basin through Aquifer Mapping Eco hydrological Investigation and water Budgeting and Artificial Recharging of flood water
Institution: Centre for Water Resources (CWR), Anna University, Chennai
Overview: This study assessed groundwater potential in Walajabad Block, Tamil Nadu, using various techniques including geophysical surveys, water quality analysis, and aquifer parameters. Employing innovative methods like set IV weighted overlay, it identified 77%of the area as having moderate to very good potential, aiding sustainable water resource management in rugged terrains.
