“…Water losses, in general, followed the same tendency as soil losses (Table 4); however, the reductions were smaller than reductions in soil losses, which was also verified by Cogo et al (2003), Amaral et al (2008), and Ramos et al (2014). The smaller influence of soil management on reduction in water losses compared to reduction in soil losses can be explained by the fact that the soil has a limit of water absorption and storage, according to the soil capacity.…”

Water erosion, the main factor in soil degradation, is strongly influenced by soil cover and management. The objective of this study was to determine soil and water losses under natural rainfall conditions from 1993 to 2012 in the southern Santa Catarina Plateau, Brazil, in 3.5 × 22.1 m plots with crops in rotation to study the following management treatments: conventional tillage (CT), minimum tillage (MT), and no-tillage (NT), and a treatment with bare soil (BS). The soil cover remaining after tillage was negatively affected by the increase in soil tillage intensity. Soil losses were strongly affected by the management system, while water losses were less affected. Soil losses were 85.29, 6.41, 2.00, and 0.82 Mg ha -1 yr -1 in the BS, CT, MT, and NT treatments, respectively, while water losses were 38, 24, 15, and 9 % of the rainfall, respectively, in the annual mean. Soil losses in spring/summer were similar to those of autumn/winter in the CT, MT, and NT treatments, while water losses were influenced by the time of year in all soil management systems. The accumulated soil losses in the MT and NT treatments tended to stabilize over the period evaluated, whereas they increased an average of 88.12 Mg ha -1 yr -1 in the BS and 7.23 Mg ha -1 yr -1 in the CT treatments. The accumulated water losses had a linear response, with positive angular coefficients for all treatments. The relationship between annual soil and water loss data was significant in the BS treatment; in the CT, MT, and NT treatments, this relation was not significant.

“…The highest AD in conserved areas suggests a greater protection of the soil against erosion processes, especially by water, decreasing soil and nutrients losses (Martin Filho et al, 2009;Ramos et al, 2014), and consequently increasing the vegetation resilience. The highest density of species in conserved areas also increases the production of litter, levels of organic matter, infiltration capability and storage of water in the soil, thus reducing the susceptibility to water scarcity (Mendonça et al, 2009).…”

“…Essas mudanças afetam diretamente a dinâmica da água nas bacias hidrográficas. O uso inapropriado do solo degrada a superfície do terreno (RAMOS et al, 2014;BERTOL et al, 2015), diminui a sua capacidade de infiltração e reduz a qualidade da água (DESSIE & BREDEMEIER;2013;BUCCI et al, 2015;NAUBI et al, 2016).…”

RESUMOO aumento da interferência do homem no meio ambiente provoca mudanças que afetam a dinâmica da água presente nas bacias hidrográficas. Dessa forma, a qualidade e a capacidade de infiltração da água no solo são reduzidas. As análises morfométricas de bacias hidrográficas fornecem parâmetros da rede de drenagem, além de limites e detalhes da topografia, o que possibilita planejar medidas de conservação da água. O Sistema de Informação Geográfica é de fundamental importância na caracterização automática da morfometria das bacias. O estudo objetiva descrever as características morfométricas da bacia hidrográfica do Córrego Manhuaçuzinho e fornecer informações para o gerenciamento dos recursos hídricos. O software utilizado na delimitação da bacia foi o ArcGIS 10.3.1; as cartas do IBGE foram referência para sua localização e os parâmetros morfométricos foram utilizados para sua caracterização. A bacia de Manhuaçuzinho foi classificada como alongada, fato que diminui o risco de enchentes. Sua ordem é 5 com padrão de drenagem predominante dendrítico, possui declividade média de 20,90% e apresenta elevada variação de altitude, com valores entre 731 e 1630 m. A partir dos estudos morfométricos realizados conclui-se que a bacia possui características propícias para o armazenamento de água da barragem, mas a grande amplitude altimétrica favorece o escoamento superficial, por isso são necessárias medidas que intensifiquem os processos de infiltração.
