چکیده

The Sono river basin (SRB) is an important ecological area located at the Cerrado biome, which encompasses several environmental protection units, highlighting Jalapao State Parque. In order to assist water resource management, this paper developed a hydrological simulation of SRB, delineated Jatoba station (drainage 16,862 km²), using SWAT model, and determined spatial distribution mean, maximum, minimum specific yields (REmlt, REmin, REmax) in basin. performance model was evaluated Nash-Sutcliffe efficiency (NSE) percentage bias (PBIAS). For monthly calibration validation periods, respectively, NSE values 0.55 0.56 PBIAS 8.2% -10.2% were obtained. daily 0.40 0.41 -11.2% These results indicate that able streamflows SRB. addition, REmlt, REmin REmax maps showed areas are biggest producers compared with other parts Therefore, achieved study fundamental tools for resources management region.

Modeling of the Hydrological Cycle of a Forest River Basin and Hydrological Consequences of Forest Cutting

Physically based model of the hydrological cycle of a forest basin was developed. The model includes description of processes of liquid water and snow interception by forest canopy, snow accumulation and melt, vertical soil moisture transfer and evapotranspiration, overland, subsurface and channel flow. The case-study has been carried out on the basis of experimental observations on the Valday ...
