The present work of Investigation consists in carrying out the essential studies, for the later construction of a dam of loose materials on the Santanero river, in the Cajamarca region. It is known that the area of the basin is arid, also with long periods of low water which are linked to agriculture, which is the main source of income for the inhabitants. In this thesis, the study of the geotechnical parameters was carried out. In the first place, we were able to determine that the dam under construction should be made of loose materials, taking advantage of the nearby quarries. Taking into account the demands and offers, we reached the conclusion that we would have a useful volume of 1.8 MMC, which was sufficient, since it manages to meet the annual guarantee by 80%. With the volume, the curve - volume and with a pre design of the drain, we obtained a crown coronation height of 2288 meters above sea level, and 2259 meters above sea level for the dam itself. This was used to perform a leak and stability analysis with GeoStudio © software. In principle, the study was carried out with the SEEP © program, achieving a stationary and transitory analysis for the rapid desembalse scenario. The filtrations we were given as result were few, because they only occur along the dam, since the subsoil had a surface layer with very low permeability. With the second study we used the program GeoStudio©, in the different scenarios that were required: which were: end of construction, long term, after rapid disbanding and with a combination of earthquake with the previous ones. At the end of the study, we concluded that the geometry chosen at the beginning was not adequate and this had to be reformulated for the slope upstream, since there was a failure in the rapid desembalse with earthquake. The proposed solutions were the micro piles, which would use as a screen, a lower berm with castling and / or a decrease in the slope of the slope. Finally, by eliminating the first two options of the proposal, because they only minimized instability. It was chosen to increase the slope from 2H: 1V to 1.5H: 1V. since with the latter it was possible to achieve greater stability compared to the previous ones. Even the leaks decreased. An analysis was also made to the drains, in the first instance the study of bottom drainage was made with an entrance to 2259 meters above sea level and an exit to 2288 meters above sea level, of which its losses do not give a problem for its operation. The energy dissipation basin was defined, taking into account that the river bed is at 2260 meters.
