Biomass Model and Water Balance Application for Watershed Drought Analysis

The hydrological cycle is an important process for monitoring various functions of the landscape. However, changes from land use and natural events, such as drought, have caused several problems in watersheds, water scarcity episodes. Thus, creation tools these events environmental research. Therefore, objective this work delimiting potential biomass elaborates balance Serra Azul stream sub-basin (MG) to analyze influence drought on storage hydrographic basin. used methodology involved calculation Vegetation Condition Index (VCI), application model evaluation balance. Furthermore, a regression analysis was performed between analyzed data verify variation worsening study region. results indicated that variations contributed proving effectiveness associated VCI drought.
