“…De modo geral as estradas apresentaram problemas na maioria dos pontos observados ao longo dos monitoramentos, com manutenções insuficientes ou inexistências de sistema de drenagem, mas, em períodos secos as vias encontraram-se em melhor funcionamento, conforme Manoel e Carvalho (2018), Stolf et al, (2018), e Baucke et al, (2019). Notamos que com o tempo as estradas necessitam de manutenção para o bom funcionamento da via.…”

As estradas são muito importantes em vários aspectos, não só importantes, mas também necessárias. Possibilitam o tráfego de pessoas em busca de necessidades básicas (saúde, educação, lazer, trabalho, etc.) como também às atividades agrícolas. Portanto, o objetivo principal desse capítulo foi caracterizar e analisar o estado de conservação das estradas rurais na bacia hidrográfica do Ribeirão Paraíso, Jataí-GO, esperando contribuir com incentivo e conscientização por parte da gestão da estrada da necessidade de realizar um licenciamento ambiental para uma boa gestão: ambiental, econômica e social, para que responsabilize em arcar com despesas preventivas e mitigadoras dos possíveis e/ou presentes danos ambientais gerados. Como metodologia, utilizamos a caracterização empírica (monitoramento), com auxílio de ferramentas de Sistema de Posicionamento Global-GPS, trena, máquina fotográfica, entre outros, e os trabalhos de gabinete com seleção de informações e criação de um banco de dados da bacia necessárias à execução da pesquisa. Foi constatado que as estradas em sua maioria estão comprometidas, sem medidas de prevenção ou sem manutenção adequada, uma vez que as medidas requerem manutenções constantes para o bom funcionamento. Constatamos vários processos erosivos na faixa de rolamento e áreas adjacentes como buracos, ravinas, sedimentos e ausência de sistema de drenagem. Concluímos, portanto, que as estradas da área em questão apresentam degradação que pode prejudicar o escoamento da produção local, causando prejuízos econômicos, assim como, dificuldade de deslocamento de pessoas e veículos.Characterization of the conservation status of rural roads in the Ribeirão Paraíso basin, Jataí-GO A B S T R A C TRoads are very important in many ways, not only important, but also necessary. They enable the traffic of people in search of basic needs (health, education, leisure, work, etc.) as well as agricultural activities. Therefore, the main objective of this chapter was to characterize and analyze the conservation status of rural roads in the Ribeirão Paraíso hydrographic basin, Jataí-GO, hoping to contribute with encouragement and awareness on the part of the road management of the need to carry out an environmental license for a good management: environmental, economic and social, so that you are responsible for paying preventive and mitigating expenses for possible and / or present environmental damage generated. As a methodology, we use empirical characterization (monitoring), with the help of Global Positioning System-GPS tools, measuring tape, camera, among others, and the office work with selection of information and creation of a necessary basin database the execution of the research. It was found that most roads are compromised, without preventive measures or without proper maintenance, since the measures require constant maintenance for proper functioning. We found several erosive processes in the tread and adjacent areas such as holes, ravines, sediments and the absence of a drainage system. We conclude, therefore, that the roads in the area in question show degradation that can impair the flow of local production, causing economic losses, as well as difficulty in displacing people and vehicles.Keywords: Monitoring, Maintenance, Erosive processes.

“…Therefore, including roads in hydrological studies in watersheds is fundamental. Baucke, Pinheiro, and Kaufmann (2019) point out that because roads are built without planning and with little maintenance, they are subject to a high sedimentological contribution to water bodies, and there are few observations made by the scientific community. The studies by Tiecher et al (2014), who sought to clarify sources of suspended sediment in a watershed, found that rural roads, in rainy periods, represent almost 70% of the total sediment production.…”

Studies related to morphometric analysis are extremely important for hydrogemorphological knowledge in watersheds. However, most rural roads are not considered in these analyses. Therefore, the objective of this article was to verify if the relations between the drainage network, the relief parameters, and the road network indicate changes in the drainage dynamics of a watershed occupied by agricultural use. The sugarcane crop is an influencing factor in the increase in rural roads in the watershed and arrived in the region from 2009 onwards. Therefore, the time frame of 2005, 2010, 2015, and 2020 was chosen for the investigation. Bibliographic research and quantitative measurements were used as a methodology to extract information from the drainage network and road network through morphometric parameters. For this, ArcGIS® 10.6.1 and Excel 2019 software were used. As a result, it was identified that the watershed has a fourth-order river hierarchy; its area is 903.6 km², the drainage density is 0.45 km/km², and when rural roads were included in the analysis in 2005, 2010, 2015, and 2020, corresponding to 2.1, 2.2, 2.4, and 3.1 km/km², respectively. Thus, the average density of roads in the period was 84% higher when considering only natural drainage, increasing mainly after the insertion of sugarcane in the scenario. Therefore, it is concluded that the analysis of morphometric parameters is essential to generate new knowledge about the studied watershed. Rural roads should be included in the analysis since they influence the hydrogeomorphological aspects of the watersheds. In this case, the increase in drainage density is directly related to the increase in roads and sugarcane. With the inclusion of these in the morphometric analysis, the watershed increases its drainage capacity, significantly altering the hydrological response in hydrographic watersheds.
