Figure 3
Water available and water needed on the huerta of Vila-real.
Sources: Garrido (2004, 163) provides information about what was cultivated on the huerta of Vila-real, and Ministerio de Fomento (1918, I, 413–415) offers data about the amount of water needed by each crop. Information about the flow rate of the river Mijares from 1915 onwards can be consulted at http://hercules.cedex.es/anuarioaforos/afo/estaf-datos.asp?indroea=8005 The Vila-real weir diverted 23.33% of the river’s discharge, and I have considered that 30% of that water was lost by evaporation and seepage.
