HYDROLOGICAL MODELING USING SWAT IN THE DECISION-MAKING PROCESS FOR THE CONSERVATION OF RIVER BASINS.

Abstract

The conservation of watersheds is a concern in all countries because of the scarcity of water for capitation and use and the anthropogenic degradation of this natural resource. Thus the objective of this study is to make a systematic review on the themes ecosystem service, hydrological modeling using the SWAT model. Emphasizing the importance of this theme in the decision-making process in the management of water resources. The research is exploratory, having as main method the literature/scientific review. The bibliographic survey used was carried out on the Scopus platform, in chronological order in the range from 2018 to 2022.  The two years of the health crisis were the years of greatest scientific production. Two publications stood out for the number of citations: A review of SWAT Applications, performance and Future needs for Simulation of Hydro-Climatic Extremes and, Comparison of the SWAT and Invest models to determine hydrological Ecosystem service Spatial Patterns, Priorities and trade-offs in a Complex Basin, both published in 2020. The most prominent countries in research publications in the area of Environmental Science were China, USA, Canada, Germany, Brazil and Norway. The relevance of studies involving this theme become evident because they are tools used in the decision-making process in water management, showing up as a vast field for research in Latin America and South America, but specifically in Brazil for its continental dimension and its diversity.
