Abstract: In temperate regions, building small dams and hillside reservoirs is a popular solution to irregular and unevenly distributed rainfalls. Furthermore, it is advised that rural communities use these tiny hydraulic structures as a means of adapting to climate change. They are essential to the water resources' survival. These dams could, however, act as sinks for material from upstream. In order to better understand siltation and the proper operation of these essential structures, it would be helpful to monitor and measure the amount of sediments in minor dams. The bathymetry or topographical surveys needed for this control and these measurements are too costly for the people in charge of these minor dams. In this regard, the triangulation of the estimated silted level is a straightforward and inexpensive method that is proposed in this work. This technique is based on measuring the accessible silted level in the dam directly. This new approach is contrasted with an alternative that is based on the dam's original Elevation-Capacity curve and is typically employed when the bathymetry is unachievable. The bathymetry and electrical tomography findings from both of them were compared, confirming the proposal method's status as the most accurate. Consequently, this approach is suggested as a novel, straightforward, and easy way to assess the degree of silting in minor dams and hillside reservoirs
