**Abstract**

The hydrologic modeling is a useful tool for integrated water management in watersheds. Its construction generally requires precipitation information and different physical parameters related with a watershed. In Mexico, the availability of official rainfall information, which is reliable and sufficient, is a challenge today. In some areas, there is the right amount of information but of poor quality, while other locations have few climatological stations. However, using the tools of the Industrial Revolution 4.0, we have satellite information that can supply additional records that are not available in the network of climatological stations. Nevertheless, it is necessary to evaluate the quality and usefulness of satellite information, for which an inter-comparison exercise between sources of information is useful and sometimes necessary. An alternative to obtain updated satellite records is the CLIMATESERV database of the GLOBALSERV. The objective of this work is to present the analysis and the results obtained from the hydrological simulation corresponding to year 1981, considering as the case study area the upper Río Conchos basin. For the generation of rainfall time series, the database of the rapid exhaust of meteorological information was used in version III (ERIC III 3.2 by its Spanish acronym) and the CLIMATESERV database.

## **1. Introduction**

In the region where the Río Conchos basin is located, the water pressure (total volume of concession water/volume of renewable water) has risen 27% in the last 14 years, increasing from 50% in the year 2003 to 77% in 2017 [1, 2]. This pressure is associated with population growth, increased irrigation land, growing urbanization, water-body pollution, aquifer overexploitation, and climate change.

Taking into consideration the above, it becomes clear that current water management in the region is not responding to the expectations of use for human consumption, the environment, and international responsibilities.

Therefore, for future decision-making about water management in the region, appropriate tools and methodologies are needed. The modeling of the rain-runoff process, which can be supported by a relational data model, is a very useful tool for the integrated water management in hydrological watersheds. This model aims to determine the amount of water available and analyze in detail the rain-runoff process in the watershed, and, thus, know the availability in the tributaries and help the decisionmaking in relation to the distribution of water resources, the proper implementation of integrated water management, and compliance with international treaties in the region. The construction of a hydrological model generally requires precipitation information and different physical parameters of the watersheds. In Mexico, the availability of official rainfall information, reliable and sufficient, is a challenge today, because there are no updated records in some regions. In some areas, there is the right amount of information but with poor quality, while other locations have few climatological stations.

On the other hand, using the tools of the Industrial Revolution 4.0, we now have satellite precipitation information that can reinforce and even supply the lack of information available in the network of climatological stations. However, it is necessary to evaluate the quality and usefulness of satellite information, for which an intercomparison exercise between sources of information is very useful and sometimes necessary. An alternative to obtain updated satellite records is the CLIMATESERV database of the GLOBALSERV. This database is made up of different satellite data sources and terrestrial source records.

The objective of this work is to present the analysis and the results obtained from the simulation corresponding to year 1981 of the rain-runoff process using the HEC-HMS software, considering the Río Conchos as the case study area—P. de la Colina subbasin located within the Río Conchos basin.
