This thesis has been developed on the basis of the specific objectives related to: evaluate the water availability of the Sama River, estimate the useful volume and the dead volume of the dam to regulate the availability of the Sama River during the rainy season, calculate the current water requirement of the Sama Valley in the current situation and simulate the use considering the regulation and the water demands with the project. In order to achieve the above objectives, the following activities have been carried out: collection of hydrometeorological information, consistency analysis, water requirement calculations for the current scenario and for a second scenario with our proposal (with project) and the development of a hydrological scheme using Weap software to analyze the adequate use of water resources. In the study of precipitation, it has been determined that the Sama river basin has practically no rainfall in the lower part of the basin, very little in the middle part and only has precipitation in the upper part of the basin where 90% of the annual precipitation is concentrated in the period from December to April and only 10% in the period of May, which is why the average multiannual precipitation is 96.4 millimeters per year, which has been determined with the Thiessen polygon criterion. The Sama river basin has a basin area of approximately 4591 km2 and a water availability of 2.25 m3/s recorded at the La Tranca station, located at the headwaters of the Sama valley, 78.3% of which is concentrated in the period from December to April, where the average flow can reach 8.335 m3/s in the month of February and can decrease considerably to a minimum flow of 0.488 m3/s in the month of November. The current demand of the Sama valley is 1,460 m3/s equivalent to a volume of 45,979 MMC/year of the 3603 ha under irrigation in the Sama valley, however, there is an unmet demand of 17,438 MMC/year mainly in the months of low water, due to the decrease in river flow, but there is also a surplus from the rainy season that is lost in the ocean with an average flow of 44,011 MMC/year. From the hydrological simulation carried out, in the low water months, there is a coverage of 40% to 60%, which is quite low. Considering the surplus volumes of water in the Sama River during the rainy season, it has been proposed to use the waters of the Sama River during this period in a multi-year regulation dam with a total storage capacity of 120 MMC, of which we consider an operability of 50 years, therefore, there would be a dead volume of 36 MMC, therefore, the useful volume of the dam would be 84 MMC. It is important to note that the reservoir would have a multi-year regulation, which means that the volumes of water stored in the dam would help mitigate water deficits in dry years and would also allow for the expansion of the agricultural frontier by 1514.12 hectares on the right bank of the Sama River.
