Sažetak
This paper presents the evaluation of three mathematcal models for estimation of 10-day drain discharge using weather, pedological and phenological parameters. One model uses modified Palmer's procedure for calculation of water balance components and the second two use empirical multiple linear regression. The models have been applied on data of an ameloration experimental field in central Croatia (South-Western part of pannonian Lowland), where a set of average 10-day air temperature and relative humidity data, the average wind speed, cumulative precipitation and drain discharge amounts, insolation and soil moisture data and the vegetation indexes have been collected. The experiment has been performed during the period 1990-1992. The models have been tested comparing estimated and observed 10-day drain discharge amounts for 1992. All models give acceptable cumulative results although their accuracy depends on the season.
