This work is prioritized on evaluating tracer methods that are used for the purpose of detecting the drainage point in shallow water reservoirs. Water loss exhibited on a large spatial scale through leakage, seepage, or deep percolation, needs to be researched by simulating the environment and conditions that lead up to it. Literature on methodologies and shallow water flow from various authors significant to our work was used in the description of the processes and tracing techniques involved in our experiment. A physical-based model was set up in a laboratory setting, consisting of a water input system and a soil flume with a 2x2 m area space. Objectives comprise a qualitative and quantitative evaluation of the shallow surface water flow and tracer movement towards the sink point, as a result of using an appointed tracing technique. In regards to the goals, the experimental proceeding was divided into the flooding and detection phases. A constant steady discharge was used to flood the flume, for the re-enactment of natural shallow flow conditions, and a dual thermal-dye tracer was injected through cups for estimating flow velocities. Three parameters were defined and modified, for the means of investigating the detection of the sink point, through multiple experimental trials. Thermal tracer was chosen as a representative for all of the experiments due to the available equipment and image quality. Results gathered from the experimental analysis helped discuss the merits and weaknesses of this kind of experimental approach. In the case of flooding, the empirical data served as a means to investigate the shallow water movement across the barren surface that serves as a background for tracer techniques. Various results from the detection of the sink point were compared, and the most favourable and unfavourable results were taken as representative of the thermal tracing technique
