“…It is currently possible to determine the characteristics of the basin with great precision thanks to the large number of data provided the new technologies [17]. Specifically, and mainly due to the systems of geographic information (GIS) and spatial data infrastructure (IDEE).…”

The time of concentration, that is the time it takes for a single "drop of water" to move superficially from the most distant point of the watershed to the exit point, is a fundamental parameter of the hydrological analysis. Many studies have been conducted to propose empirical formulas to calculate the time of concentration. One of the best known is the Temez formula based on time series data collected in accounts in Spain with areas of less than 3,000 km 2 . This expression uses the main channel length as a parameter as in many works, for small slopes is approximated by the distance between the geographic coordinates between the starting and ending points, leading for larger catchments and slopes to approaches with a high error. In this work, using a proper discretization of the curve, by using polynomial interpolation methods, we improve the calculation of the length of the main channel and therefore, we provide a more reliable method for calculating the time of concentration using the Temez expression. We illustrate the proposed scheme with different numerical examples comparing the results with those provided by other methods.

“…In geographic information systems (GIS), digital elevation models (DEMs) have been employed more and more frequently for basin delineation since they are tools used for the extraction of a large number of parameters necessary for a hydrological study [26]. However, in developing countries, urban basin divisions are usually not available [27,28].…”

Urban storm drainage is fundamental for the well-being of the population of cities with torrential rainfall regimes because it is essential for the rapid and safe disposal of stormwater runoff. However, it is not uncommon for hydrological studies to determine the design flow of storm drainage works carried out in the same urban basin using different criteria depending on the experience of the person performing them. This can represent a problem when integrating and reviewing the results of hydrological studies carried out by different hydrologists. To address this problem, we propose a methodology consisting of methods used by various authors to determine the design flow rate in urban hydrologic studies. We suggest using a novel method to delineate urban basins based on photogrammetry obtained through flights with unmanned aerial vehicles. Subsequently, the necessary parameters are obtained to define the intensity–duration–return period curves, the runoff coefficients, and finally the design flow rate. The contribution of this article is technological. In this sense, a new methodology is proposed that applies existing knowledge to solve a practical problem observed in the field of urban hydrology and storm drainage. The case study is a basin with frequent flooding located in Culiacan, Mexico.

Los modelos hidrometeorológicos, facilitan el control, monitoreo y planificación del recurso agua en cuencas hidrográficas, representando variables meteorológicas de forma distribuida. El objetivo del estudio, es proponer modelos hidrometeorológicos bidimensionales para cuantificar de forma precisa, las variables básicas que determinan la dinámica del recurso hídrico en la cuenca del río Atulapa, Esquipulas, departamento de Chiquimula, Guatemala. Se generaron y recopilaron datos hidrometeorológicos, con estaciones digitales instaladas y estaciones locales. Para el desarrollo de los modelos se elaboró una correlación entre altitud de las estaciones meteorológicas, como variable explicativa y registros climáticos como variable de respuesta. El modelo de escorrentía es una correlación entre alturas limnimétricas en la estación hidrométrica, como variable explicativa y el caudal óptimo de los aforos como variable de respuesta. La precipitación media de la cuenca obtenida con los modelos generados, es de 1,884 mm/año y la temperatura media de 18.92°C. El cambio de temperatura entre la parte baja y alta disminuye a razón de 1°C por cada 175 m.snm. El caudal medio anual es a razón de 0.5 m3/seg en la estación hidrométrica del Puente. Los modelos hidrometeorológico generados en la cuenca del río Atulapa representaron la variabilidad climática en forma bidimensional, permitiendo un control y monitoreo del recurso hídrico en la cuenca, para la planificación del uso sostenible. La orografía en la cuenca, definió la estrecha relación con las variables meteorológicas precipitación y temperatura obteniendo modelos de regresión lineal precisos.
