Assessing the Effect of Conduit Pattern and Type of Recharge on the Karst Spring Hydrograph: A Synthetic Modeling Approach

It is widely accepted that spring hydrographs are an effective tool for evaluating the internal structure of karst aquifers because they depict response whole aquifer to recharge events. The hydrograph affected by various factors such as flow regime, geometry, type recharge, and hydraulic properties conduit. However, effect conduit network geometry received less attention required more comprehensive research studies. present study attempted highlight impact two most frequent patterns conduits (i.e., branchwork maze) on characteristic hydrograph. Therefore, patterns, maze, were randomly generated with MATLAB codes. Then, MODFLOW-CFP was used quantify pattern, density, diffuse or concentrated Results reveal peak discharge, fast-flow recession coefficient, return time baseflow mainly respectively. In contrast, reach only reacts conditions. Large variations in density produce tangible changes coefficient.
