Title

Estimation of Runoff Using SIMTOP and BATS Schemes and Actual Evapotranspiration Using a Dynamic Vegetation Scheme in Noah-MP Land Surface Model in Neishaboor Watershed

Pages

  17-26

Abstract

 Surface water resource planning requires the estimation of water balance components at different spatial and temporal scales. Moreover, due to the inadequacy of the stations in terms of number, dispersion, and temporal data recording, numerical modeling of the land surface is necessary. In this study, the Noah-MP model was used to compare the simulated runoff by SIMTOP and BATS schemes and to evaluate the Dynamic vegetation scheme for estimating actual evapotranspiration in the Neishaboor watershed monthly scale in 2000-2009. Due to the low accuracy and dispersion of hydrometric stations, the SWAT model output was used for evaluation. To develop the model, first, the sensitivity analysis of the modeled runoff to parameters of the model was performed. The model showed the highest and least sensitivity to the soil parameter in the Clapp-Hornberger relation (b) and runoff decay factor (f), respectively. The best and the first performance of simulated runoff by BATS scheme were in mountainous areas and the evaluation criteria including R2, NSE, and RMSE were respectively 0. 81, 0. 64, and 1. 91. The second grade of performance was for the plain and the lowest values for simulated runoff were in foothills regions. Results indicate that the BATS scheme shows better results in the plain and foothills areas and the results of the SIMTOP scheme in the mountainous regions were similar to BATS results. The Dynamic vegetation scheme has been able to simulate evapotranspiration changes along with the stages of plant growth. The mean of annual evapotranspiration estimated by the Noah-MP model was 305 mm.
