Within the Jubones river basin, soil recovery practices are in high demand, which is why it ends up being harmful to the area. The objective of this research is to determine the aggressiveness of precipitation in the Jubones river, and to analyze its temporal and spatial distribution during the period 1980-2000. Monthly data recorded for 20 years were compiled, creating an information base for the missing data, which were completed with the arithmetic mean and Q ratio methods. The aggressiveness of precipitation was determined by applying the Fournier (FI) and Modified Fournier (MFI) indexes. The trend of precipitation was also analyzed using the Mann-Kendall statistical test with the help of the TREND software. The correlation of the variables with respect to the IF showed two ranges, very low and low, while the IFM showed three ranges: very low, low and moderate. With respect to the results, the concentration of the moderate range with respect to the MFI is found in the cantons of Pucará, Zaruma, Pasaje and part of Girón, so the productive and economic losses will not be the majority due to the low rainfall in the area. The correlation analysis between the variables of altitude, latitude and longitude with respect to the study indices determined that there is a low relationship, this because the percentage of R2 ≤ 0.5. According to the two indexes, within the Jubones river basin, the aggressiveness is relatively low (93.33% of the total area) because the indexes are between the very low to low ranges. |
