**Figure 5** shows the output hydrograph of the hydrological simulations with the two sources of precipitation information mentioned above.

### **3.2 Calibration**

The calibration of the model involved a quantitative assessment of the hydrological response of the subbasin. This process was done by comparing the observed hydrograph with the simulated hydrograph. This is essential for the evaluation of the model, to compare the distribution and variations of the data [6]. **Figure 6** shows the result of this comparison.

#### **3.3 Statistical evaluation**

The performance of the results of the model was assessed with several statistic models, such as the coefficient of determination, correlation, standard deviation of observations (RSR), and efficiency of the Nash-Sutcliffe (NSE). **Table 1** shows the results of the statistical evaluation of the simulations versus the observed historical information.

## **4. Discussion and conclusions**

The hydrological model created using the HEC-HMS software simulated very well the rain-runoff process of the Río Conchos-P. de la Colina. The precipitation information and different physical parameters of the watershed came from different sources. Talking about the precipitation input parameter, time-series were generated based on two sources of information: the first one with official information from climatological stations reported by the CONAGUA, and the second source with information from the CLIMATESERV database of the GLOBALSERV, which combines multiple satellite data sources and observations terrestrial. Quality and usefulness of the satellite information of precipitation were evaluated, by means of an intercomparison exercise between the time series coming from the two sources, obtaining a difference of 1.63% between them.

Based on this analysis, the result is a hydrological simulation model of the subbasin related to year 1981. A benchmark analysis of results and a statistical evaluation of the model were carried out. The analysis indicated a good behavior of the model
