Table 14.2: Calculation of the storage volume for the collection of precipitation in Antalya (Turkey). Precipitation Pre (Muller 1996); STPm with (14.5) and EVpond = 0; ET0 from Fig. 13.1. CWRm=1.04 x ET0 x dm (see Example 1)
STPy = Epos STPm = 608.2 l/(m2 year)
Defy = Eneg STPm = 1,651.4 l/(m2 year)
STPy > CVmmax:
Case 2(a): Storage volume VST = STPy = 608 l/m2
The storage is empty from July until October. The crop water requirement can be covered for 8 months from November to June by rainwater with a storage volume of 0.61 m3/m2 greenhouse area.
