The marginal belts are public domain hydraulic goods. They are conformed by the immediate areas superior to the banks of the sources of water, natural or artificial. The dimensions in one or both margins of a body of water are fixed by the Water Administrative Authority, according to the criteria established in the Regulation, respecting the established customs and customs. The criteria for the delimitation of the banks are: The magnitude and importance of the hydraulic structures of the dams, reservoirs, reservoirs, diversion channels, among others; The necessary space for the construction, conservation and protection of the riverside defenses and the channels; The necessary space for the public uses that are required; The maximum flood or avenue of the rivers, lakes, lagoons and other natural sources of water. By means of hydrological and hydraulic criteria, the analysis for the delimitation of the lagoon reservoir has been carried out. For this purpose, the physiographic characterization of the Lagunillas subaccount, which has an area of 836.55 km2, is found between 5 212 and 4 160 meters above sea level, presenting a very elongated shape. With data of maximum precipitations in 24 hours, the consistency analysis was performed, besides a statistical analysis of Jumps and Trends; Using the Student and Fisher tests for a significance level of 5%, resulting in values calculated as non-significant, which shows that we have consistent data for the hydrological analysis. Completion and extension of data were performed using the hydrologic model HEC-4 (Monthly Streamflow Simulation) developed by the Hydrologic Engineering Center of the United States of America. Thus obtaining complete annual series. The annual historical series of maximum precipitation in 24 hours of the stations (Crucero Alto, Lagunillas, Quillisani, Jarpaña), have been adjusted to the theoretical distributions, Normal, Log-Normal, Gumbel, Pearson Type III, Log-Pearson Type III. The Chi-square goodness-of-fit tests, Smirnov Kolmogorov, have been performed in addition to their graphical verification, resulting in the best fit: Log-Normal distribution for the Tall Cruise station, Gumbel distribution for the Lagunillas station, Normal for the Quillisani station, the Log-Pearson Type III distribution for the Jarpaña station. Extreme events of maximum precipitation in 24 hours have been calculated for return periods of 10, 25, 50, 100, 200, 500, 1, 000 years. Thus we have also obtained the weighted or average rainfall, for different periods of return, of the Lagunillas sub-basin, through the methodology of the Polygon of Thiessen. Time coefficients were used to obtain precipitations for different duration times, and the intensity equation was calculated by multiple linear regression; Applying the intensity equation we obtained the design hietograms, for a storm duration of 12 hours, for periods of return of 10, 25, 50, 100, 200, 500, 1, 000 years. The hydrological basin has been modeled in HEC-HMS using the parameters of the rainfall-runoff transformation (physiographic parameters, concentration time, delay time, number of curves, abstractions) Return of 10, 25, 50, 100, 200, 500, 1000 years; Obtaining the peak flow values from 185.90 to 841.50 m3 / s. The levels and hydraulic volumes of the Lagunillas reservoir were determined, establishing the NAME (Extraordinary Maximum Water Level) levels, 4 169.23 which is the maximum traffic level for TR = 1 000 years. By means of the transit of avenues through the Lagunillas reservoir, the outflows have been determined in the landfill, for the different periods of return; Having an input flow of 841.50 m3 / s for a return period of 1 000 years, an output flow of 18.00 m3 / s, generating a tie rod on the 0.43 m spout. By means of the hydrological and hydrological criteria, the boundary of the water body has been demarcated between the NAMI (Minimum water level), elevation = 4 157.26 meters and the NAME (Maximum extraordinary water level) = 4 169.23 masl. A minimum width of 25.00 m is taken for the delimitation of the marginal belt, because the area is close to rural areas, with few population, and there are no channeling works. And by means of the calculations it is shown that the work of damming has the capacity to be able to evacuate the maximum extraordinary flows of income. These data will serve to define definitive marginal bands, however, it is necessary to keep in mind in addition to the hydrological and hydraulic criteria, other technical criteria such as: Environmental, social and legal aspects, since they often have a significant influence on the establishment Of the delimitation of the marginal belts. The hydrological study to determine the river banks, which serve as the basis for delimiting the marginal belt of a body of water, is done with the aim of establishing the dimensions and location of areas and spaces intended for the activities and uses of: River courses and bodies of water; Free traffic routes, access roads, monitoring and / or maintenance of river courses and water bodies; For access to dams, reservoirs, reservoirs, other catchment and diversion, irrigation canals, drainage works, access areas for navigation infrastructure.
