| Abstract | Understanding groundwater-surface water interaction is critical for both quantitative and qualitative estimation of exchange flux between these two water bodies. A comprehensive review of the literature identified the reach-scale approach addressing streambed and aquifer as relevant for GW-SW interaction and the catchment-scale approach considering only the aquifer properties. An analytical approach developed in this work, considering a 2D GW-SW system for a losing stream, bridges these two approaches. The model incorporates streambed conductance and aquifer transmissivity as governing factors and introduces a critical conductance value (CV) to delineate streambed-dominated and aquifer-dominated scenarios in flux estimation. Furthermore, the study provides recommendations for head measurement locations based on stream width, aquifer transmissivity, and streambed conductivity. Narrow streams with low-permeability streambeds and highly transmissive aquifers require measurements near the stream edge, while wider streams necessitate measurements at larger distances. While the model effectively simplifies GW-SW flux quantification, it is limited to symmetric and losing stream configurations, suggesting opportunities for future extensions to gaining systems. |
