“…One of the good ways to employ IPM to detect the concentration of the salinity of river water in the saline wedge is using the Beer-Lambert Law (BLL) (DF Swinehart, 1962;Alireza Khoshkonesh et al, 2021). This methodological integration is informed by the work of (Ghisalberti & Nepf, 2005;Ghaffari & Tavakoli, 2022;Firozjaei et al, 2023;Naeeni et al, 2023), who previously applied BLL to determine concentration profiles in flows through porous media.…”

This paper presents an innovative approach integrating the Image Processing Method and the Beer-Lambert Law to study Sea Water Intrusion in riverine systems. Using an experimental setup, this study characterizes the dynamics between saline and fresh waters, providing detailed spatial and temporal salinity distribution analyses. The Beer-Lambert Law is employed to convert image pixel data to accurate concentration measurements, essential for understanding the diffusion and mixing processes of saline wedges. This study not only bridges technological advances with hydrological research but also provides crucial data for water resource management in coastal areas affected by Sea Water Intrusion. The integration of the Image Processing Method and Beer-Lambert Law exemplifies a significant advancement in environmental monitoring, promoting sustainable water resource management in regions vulnerable to saline intrusion. Results showed that the concentration of the salt water is decreased when it flows upstream horizontally. also, the concentration of the saline water is decreased vertically, due to the salt and fresh water mixing.

The objective of this investigation is to obtain a more profound understanding of the effective parameters of the velocity caps for bottom intake systems, utilizing particle image velocimetry (PIV) and OpenFOAM. Observations indicate a higher probability of surface vortex formation in square types compared to circular ones, with the vortex being formed downstream of the caps. Additionally, the flow pattern reveals that the flow whirls in a more favorable path into the circular caps as opposed to the square ones. Through both experimental and numerical comparisons of three shapes (rhombus, square, and circle), it becomes evident that the circular type outperforms the other types in terms of discharges through the intake, showing an improvement of about 8%. The results indicate that flow depth and height of the velocity caps are positively effective parameters for the flow rate, with respective influences of 90% and 30%. In contrast, the interaction between the flow and caps intensifies with an increase in the distance of the intake opening from the bed, which plays a negative influence on the flow rate. Enhancing the number of blades in caps proves to be the optimal approach for generating a smoother flow with minimal impact on the flow rate. Numerical simulations show a 50% reduction in cap height leads to a significant 33% decrease in flow rate. Additionally, rotating the square cap by 45° into a rhombus aligned with the flow direction results in a 7% discharge flow rate increase.
