This study presents a comprehensive approach utilizing Computational Fluid Dynamics (CFD) and Geographic Information Systems (GIS) to assess dam break risks with a specific focus on the Nagarjuna Sagar earthen dam. The study examines the numerical analysis of water flow dynamics resulting from a dam break. To depict this phenomenon, a two-dimensional numerical model employing the volume of fluid method was developed. The mathematical framework incorporates the Reynolds-averaged incompressible Navier-Stokes equations with the turbulent k-e model and was employed. The computational approach employed in this study is the SIMPLE algorithm. The CFD analysis involved meshing with 42,282 nodes and 41,680 elements, while boundary conditions included one velocity inlet and three pressure outlets open to the atmosphere. The flow was initialized with a 5 m dam site, scaled down at 1:10 (1 meter in the model representing 10 meters in reality). Data were collected for various time intervals (1s, 2s, 2.5s, 3s and 5s), The results of this study reveal the flow velocity patterns following dam break events for the specified time intervals. The outcomes are presented in terms of velocity magnitude vectors, static pressure, dynamic pressure, total pressure, turbulence kinetic energy, volume fraction contours and velocity magnitude profiles at different distances from the dam site (1m, 2m, 5m and 7m). A total of 250 iterations were performed to achieve these results, providing valuable insights into the dynamics of dam break scenarios. This research contributes to a better understanding of the potential consequences of dam failures and aids in improving risk assessment and mitigation strategies for dams.

The design and prototyping processes have undergone significant transformation due to the emergence of E-Design and Virtual Prototyping in a time marked by remarkable technological progress. This study examines the significant influence of digital aspects on several industries, providing a comprehensive analysis of their potential for transformation. E-Design comprises a wide range of digital tools and processes that aid in the inception, development, and refining of design ideas. Through the utilisation of computer-aided design (CAD), virtual reality (VR), and augmented reality (AR), E-Design has emerged as a platform that facilitates novel opportunities for creative expression and collaborative endeavours. This technology empowers designers and engineers to surpass the limitations imposed by geographical distances, thereby promoting international collaboration and facilitating the emergence of interdisciplinary creativity. In contrast, Virtual Prototyping provides a dynamic platform that enables the iterative enhancement of prototypes, free from the restrictions imposed by physical constraints. By employing intricate simulations and digital twinning techniques, this approach expedites the cycle of product development, diminishes expenses, and mitigates the adverse effects on the environment. The rise of Virtual Prototyping has facilitated equal access to prototyping, hence enabling startups and small enterprises to engage in the process. This study examines case studies in several industries, including automotive, aerospace, architecture, and healthcare, to demonstrate the transformative impact of E-Design and Virtual Prototyping on product development and project lifecycles. This study investigates the obstacles and ethical implications linked to E-Design and Virtual Prototyping, encompassing concerns regarding data security, intellectual property rights, and the digital divide. This highlights the necessity of practising responsible innovation and implementing ethical principles in order to effectively navigate this revolutionary environment.

ABSTRACT The majority of the world’s waste does not go through the recycling process. Moreover, in the suburbs, waste growth and disposal impose a significant risk to the environment. Two distinct waste materials, such as palm oil fuel ash (POFA) and sugar cane bagasse ash (SCBA), are used as basic materials in this research, with weight fractions of 0%, 5.0%, 10.0%, 15.0%, 20.0%, and 25.0%, respectively, to substitute for grade 50 MPa concrete. Mechanical properties such as flexural strength, tensile and compressive strength of hybrid reinforced blended concrete were examined in the primary phase at 28 days of age. The study proposed an alternative mixture for each hybrid fibre combination. The durable properties such as sorptivity, saturated water absorption, acid resistance, and sulphate resistance of quaternary blended concrete with optimum hybrid materials were studied in the secondary phase. From the experimental investigation, mechanical properties are enhanced, and higher compressive and flexural strength are achieved as 64 MPa and 7.93 MPa in addition to 20% POFA and SCBA particles. The durable properties of quaternary blended concrete are enhanced properties due to the addition of hybrid materials.
