Resumo(s)
The São Nicolau Island has recently benefited from its first dam, the Banca
Furada. In a region where water availability is limited and it is critical to manage this
resource.
This work aims to draw up a proposal for improving irrigation management for
the irrigation area of the Banca Furada dam.
To prepare this paper was performed a socio-economic survey to farmers who
will benefit on the irrigation perimeter
Were selected 12 crops within the most commonly used by farmers in the area
and raised three rainfall scenarios. The irrigation crops consumption was achieved in
the three scenarios and then proceeded to the simulation of reservoir operation for the
same scenarios with "Simula" programme in VBA (Visual Basic) developed by Pro-
Sistemas. As result it was found, that the irrigation areas cannot depass 36 ha, 41 ha
and 55 ha, for scenarios 1, 2 and 3 respectively.
Crops showed a gross margin exceeding 1,000 euros.
The water consumption of crops does not differ much between scenarios, with
two water consumption peaks on the perimeter, from November to February and from
March to June.
