The viability of civil engineering projects depends to a great extent on the representative climatic conditions of the areas where the works are located.In this regard, the determination of the characteristic rainfall of the project area is of vital importance.From there it follows that a correct estimation and dimensioning of drainage systems and hydraulic structures, guarantees the operation and useful life of projects such as roads, airports, dams, bridges, urbanized areas and farming areas.The purpose of this document is to present a data set of maximum 24-hour precipitation and the elaboration of the IDF curves for all the active hydrological stations, located in two sub-regions to the south of the department of Sucre (north of Colombia); called the sub-region of La Mojana and the subregion of San Jorge.The geographical location of these territories and their proximity to three of the most important and mighty rivers in the country (Magdalena River, Cauca River and San Jorge River), make this area one of the most fertile in Colombia and with high potential to be a agricultural and agro-industrial pantry, being able to generate a great impact on the country's GDP.To obtain the precipitation data, the formal request procedure for precipitation data was followed before the Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM) and for the elaboration of the IDF curves, the procedure recommended by the Instituto Nacional de Vias (INVIAS) was used, set out in its Manual de Drenaje de Carreteras.The set of precipitation data and IDF curves provides valuable information for future projects that are intended to be carried out within the Mojana and San Jorge subregions, as well as serving as a guide for the development of studies in other regions with similar hydrometeorological characteristics
