Analyze the following figures related to sediment transport in different stations:
Figure 22 - Historical behavior of monthly total sediment transport for the Paicol station (21087070) - Páez River.
Figure 23 - Historical behavior of monthly total sediment transport for the Jardín Hda station (21057060) - Yaguará River.
Figure 24 - Historical behavior of monthly total sediment transport for the Puente Balseadero station (21047010) - Magdalena River.
Figure 25 - Historical behavior of monthly total sediment transport for the Puente Santander Automática station (21097070) - Magdalena River.
Figure 26 - Liquid values. Regression analysis of the sum of the Paicol, Yaguará, and Puente Balseadero stations vs. Pte Santander (1973-1988).
Figure 27 - Solid values. Regression analysis of the sum of the Paicol, Yaguará, and Puente Balseadero stations vs. Pte Santander (1973-1988).
There is a high correspondence between the flow rates of the Pte Santander station and the sum of the affluents to this reservoir registered at the Paicol, Pte Balseadero, and Jardín Hda stations.
The Yaguará River basin is the hydrological unit with the highest sediment production per unit of surface area.
The main use of the Yaguará River is the irrigation of semi-annual crops, which has generated a marked deforestation and serious erosion problems.
The main avalanche that occurred during the operation period of the Betania reservoir was in June 1994, estimated to have brought approximately 110 Hm3 of sediment with a maximum flow rate of 2109 m3/s.
The sediment transport values for the Puente Santander Automática station decreased significantly after the construction of the Betania reservoir.
The data for the period from June 1994 to December 1996 are missing for the Paicol station due to the possible loss of the station caused by the Páez River avalanche in June 1994.
a) I, II, and III are correct.
b) II, IV, and V are correct.
c) I, III, and VI are correct.
d) IV, V, and VI are correct.
