The mining of sand resources from rivers areas especially in Perak (Malaysia) and Yogyakarta (Indonesia) state is a common practice and may lead to destruction of public assets as well as impacts or increase stress on commercial and noncommercial living resources that utilize these areas. This study was carried out to determine possible river sand removal capacity and their consequences towards Perak River (Malaysia) and Progo River (Indonesia). Acoustic Doppler Current Profiler is utilized to make river profiler in term of velocity meshes and river bed depth. It also could measure the total discharge of a particular cross-section. Resistivity Survey is used in determining the availability of potential suitable soil the study area and the equipment could measure subsurface profile up to 80 meters depth. Van Veen Grabber and Helley Smith sediment sampler are used to collect bed soil samples and determine sediment transport at the time of sampling. These two methods could estimate the suitability of available sand material and the flux of sediment transport locally.
