Figure 6. Monthly floods frequency in Almas- Agrij Depression (1976-2004)
Figure 7 shows the maximum debits on rivers in Almaş-Agrij Depression. Here the
maximum debits had values between 150m 3 /s on Almaş river, in Hida, and 220 m 3 /s, on
Agrij river, in Românaşi. The highest risk of inundations took place in the year 1989
and ten years after, in 1999, when the maximal debits of floods have been recorded. In
1982 and 2001 the risk was serious, too. However the maximal debits of floods had
minimal values in some years (such as in 1984).

Figure 7. Maximum debits of floods on rivers in Almas-Agrij Depression (1981-
2004)
The maximum debits determined in Cluj and Dej Hills within years 1976 and 2004 had
values between 44.1 m 3 /s on the Nadăş river, in Aghireş, and 146 m 3 /s on Lonea river,
in Luna de Jos.
In the Almaş-Agrij Depression and in Cluj and Dej Hills the multiannual maximum
debits have varied between very large limits, depending on numerous factors
(climacteric conditions, receiving basin surface etc.) The maximum debits were
