Answer: two solar eclipses separated by one Saros cycle will have the same geometric characteristics (they will both be total, or partial or annular).
A Saros is a period of time of about 18 years 11 days and 8 hours and represents the time needed for the system composed by Moon, Earth, and Sun to return to its initial position.
Indeed, this is due to a natural harmony of the Moon’s motion: it takes 29.53 days to complete one orbit around Earth (Synodic Month), it takes 27.21 days to pass from the same node of its orbit (Draconic Month) and it takes 27.55 days to go from perigee to perigee (Anomalistic Month); the composition of these three motions gives one Saros of around 6585.3 days, composed by 223 Synodic Months, 239 Anomalistic Months and 242 Draconic Months (with a precision of few hours).
It has been observed that after one Saros cycle Moon, Earth and Sun are in the same initial position, therefore an eclipse occurring on day 1 of two consecutive Soros cycles would have the same geometric characteristics, which means that one Saros can be considered the periodicity of solar and lunar eclipses.
Due to the fact that a Saros is not composed by a whole number of days (we have a remainder of 8 hours), the two eclipses won’t be visible from the same location on Earth due to the rotation around its axis. It takes about 3 Soros for this to happen.

Based on cartographic material from three time periods during the nineteenth and twentieth centuries, the impact of river capture, which started in the middle of the nineteenth century, on transformations of the watershed and hydrographic network of two Lithuanian rivers, Ula and Katra, is analysed. It has been determined that river capture conditioned marked transformations of water supply and distribution. As a result of the capture, the area of Ula catchment has increased by 62% and its mean discharge by 63%, whereas the area of Katra catchment decreased by 23% and its mean discharge by 27%. The total area of the five largest lakes in the recent Ula catchment has been reduced by 95%. The transformations of water resources in the Ula catchment since the first half of the nineteenth century are the following: Ula runoff volume has increased almost by 100 million m3/yr whereas the water volume of lakes has been reduced by almost 30 million m3.
river ecosystems support a disproportionately large fraction of its biodiversity, while acting also as significant corridors for the movement of plants, animals and nutrients
