Impact of Direct Soil Moisture and Revised Soil Moisture Index Methods on Hydrologic Predictions in an Arid Climate

Table 5

Comparison of maximum flow predicted by SMI and SMCII methods during model validation.

Stream flow > 500 (m^3/s)	SMI	SMCII	Relative error* %
			SMI	SMCII
985	118	824	88.0	16.3
527.5	21	366.6	96.1	30.5
1284.5	665	746.5	46.8	40.2
596	500	434.6	16.1	27
854	680	703.2	20.4	17.6

Negative values are overestimations, and positive values are underestimations.
