• The Department of Civil Engineering at SRKR Engineering college, Bhimavaram was started in 1980 and is as old as the department itself. It has earned a reputation in the state of Andhra Pradesh in general and in the coastal districts, for its dedicated teaching and consultancy. While the department basically focuses on teaching, catering mainly to undergraduate civil engineering students and to a select section of post-graduate students of Structural Engineering, it also offers a lot of industrial consultancies in the areas of Geotechnical Engineering, Structural Engineering, and Transportation Engineering. However, considering recent advancements in national and international research endeavors, the department has recognized the significance of research as a priority. Consequently, some faculty members have successfully attained doctoral degrees, while others are pursuing them. Furthermore, the department has placed a notable emphasis on scholarly publications, with the expectation that this will further invigorate research within the department.

• A significant milestone in the institution's journey is the establishment of the Centre for Sustainable Inland Aquaculture (CSIA). Inaugurated by Prof. K. Satyanarayana, Director of IIT Tirupati, the center was launched during the 90th Birthday Celebrations of the college's Founder, Late Sri Sagi Rama Krishnam Raju. The CSIA is committed to promoting sustainable inland aquaculture practices and aligns its mission with the Global Sustainable Development Goals (SDGs) outlined by the United Nations, setting a new benchmark for interdisciplinary collaboration and sustainable progress.

• Inland aquaculture is a critical sector in Andhra Pradesh, yet the prevalence of un-engineered farming practices raises substantial environmental concerns. CSIA aims to address these challenges by developing innovative technologies and sustainable solutions that can be applied locally and globally. Our center will collaborate with governmental bodies, industries, NGOs, and esteemed academic partners nationally and internationally to effectively address the environmental issues associated with inland aquaculture.

• Our research activities at CSIA primarily focus on various critical areas, including aquaculture water treatment and management, aqua waste management, waste-to-energy nexus, emerging contaminants, machine learning applications in environmental monitoring, environmental impact assessment, circular economy, and other pertinent environmental concerns. The center actively engages in a wide range of collaborations by fostering regional, national, and international research partnerships.

• The center targets to use the transdisciplinary approach in solving environmental issues. This approach encourages interdisciplinary collaboration, ensuring that diverse perspectives and expertise are incorporated into the problem-solving process. By bringing together experts from different fields, CSIA strives to develop holistic and comprehensive solutions that effectively address environmental challenges and contribute to sustainable development.

To become a leading global Centre in Inland Aquaculture Research with pollution abatement, waste-to-energy nexus, and environmental sustainability as major thrust areas.

• To effectively develop short, medium, and long-term applied solutions to enhance environmental quality.

• To identify and implement environmental initiatives and policies at national and international levels to ensure continuous improvement in environmental quality.

• To facilitate technology, transfer from laboratory research to aquaculture industries, enabling them to meet effluent discharge limits in aquaculture processing belts across West Godavari district and other districts of Andhra Pradesh.

• To establish a consortium dedicated to promoting a clean, green, and sustainable environment.

• To foster collaborations with government agencies, industries, NGOs, and prominent national and global researchers through transdisciplinary research to advance environmental quality.

• To organize capacity-building programs to enhance environmental assessment and improvement through training, education, and workforce development.

• To provide policymakers with scientific information and objective feedback regarding the effectiveness of various clean environment programs.

• To contribute to driving sustainable environmental development for the betterment of society.
