“…The use of the SWAT hydrological model on a national scale was carried out for different purposes for the management of water resources, flood risks, determination of changes in land use and occupation, estimation of water availability, agricultural yield, pesticide dynamics, climate changes, analysis of water quality, water production, granting of rights to use water resources, hydrosedimentological dynamics (Souza et al, 2009;Durães Mello et al, 2011;Silva, 2013;Fukungana et al, 2015;Pereira et al, 2016;Silva et al, 2016;Brito et al, 2017;Silva et al, 2018a;Silva et al, 2018b;Fontes Júnior & Montenegro, 2019).…”

The use of hydrological models allows to understand, evaluate and anticipate events of natural or man-made origin in a simpler and more economical way for the quantity and quality of resources in a hydrographic basin. The present work aims to perform a hydrological modeling in the hydrographic basin in the semiarid, using the SWAT model, to verify the influence of the use and exploitation of water production on the land. For this, the SWAT hydrological model (Soil Water Assessment Tool) was used. A study area located in the Jacaré Curitiba Basin, in Poço Redondo-SE, a semi-arid region of the state, inserted in the Caatinga biome and in the lower São Francisco. The adopted methodology was used for bibliographic survey, field work, hydrological monitoring, chemical and physical medicine of soil and soil, survey of land use and exploration, calibration and validation of hydrological model. The SWAT model successfully simulated or hydrographed the flow for the period from Nov/2015 to Jul/2018, duly calibrated and validated. As simulations of different land use scenarios, the greatest production of water in agricultural areas stands out, which can cause greater generation of sediments. The calibrated and validated SWAT model means a possibility for future studies in non-semiarid watersheds and then contributes to studies on water and soil management.

“…In Brazil and the world, several studies have been developed aiming to verify the effects of the land-use changes on the runoff (Coelho et al, 2014;Rodrigues et al, 2015;Pereira et al, 2016;Zhang et al, 2016;Kundu et al, 2017;Marhaento et al, 2017;Fontes Júnior & Montenegro, 2019) and sediment yield (Anaba et al, 2017;Blainski et al, 2017;Worku, Khare & Tripathi, 2017). Coelho et al (2014) detailed analysis of spatial and temporal dynamics of land use and occupation of the stream São Paulo watershed, located in the semiarid region of Pernambuco State, from 1991 to 2010.…”

Land-use change has a significant influence on runoff process of any watershed, and the deepening of this theme is essential to assist decision making, within the scope of water resources management. The study was conducted for Mundaú River Basin (MRB) using the Soil and Water Assessment Tool (SWAT) model. The study aims to assess the issue of land-use change and its effect on evapotranspiration, surface runoff, and sediment yield. Input data like land use, topography, weather, and soil data features are required to undertake watershed simulation. Two scenarios of land use were analyzed over 30 years, which were: a regeneration scenario (referring to use in the year 1987) and another scene of degradation (relating to use in the year 2017). Land use maps for 1987 and 2017 were acquired from satellite images. Overall, during the last three decades, 76.4% of forest was lost in the MRB. The grazing land increased in 2017 at a few more than double the area that existed in 1987. Changes in land use, over the years, resulted in an increase of about 37% in the water yield of MRB. Changes have led to increased processes such as surface runoff and sediment yield and in the decrease of evapotranspiration. The spatial and temporal distribution of land use controls the water balance and sediment production in the MRB.
