Analises hidrológicas para inundação são realizadas a anos, porem ainda pouco exploradas quando o assunto é voltado ao mapeamento. Este projeto tem como objetivo determinar uma análise geográfica sobre inundação, explorando os métodos disponíveis para sistema de informações geográficas, assim como explorá-los detalhadamente. Neste estudo a aplicação se deu em uma obra linear – dutovia. / This work meets projects that intend to use hydrological analysis in geographic information systems, today few explored.

In Turkey with increasing energy demand by industrialization and urbanization, hydropower seemed to be the most environmental friendly and sustainable solution for the problem. However, hydropower has also environmental effects especially when hydropower projects are numerous on a single river, and they use almost entire water in the river. Environmental flow as a new term became popular in media with increased density of small hydropower projects in Turkey. It is the required flow in the part of diversion for Run-off River type of hydropower plant in order to protect health of the river / in other words, to balance components of the river, including physico-chemical quality standards, surface and groundwater, geomorphological dynamics, social, economic, cultural and landscape values. In this study, an analysis utilizing hydrological (desktop) environmental flow assessment methods is prepared for Turkey, focusing on the Pazarsuyu Basin as a case study, and the results are compared with the applications done by the Governmental Institutions. Moreover, insufficient applications with regard to environmental flow assessment are given and reasons for public concerns are pointed out due to small hydropower development in Turkey.

En esta investigación se realiza el análisis hidrológico de la cuenca Utcubamba, y posteriormente el análisis hidráulico del río Utcubamba, para así, poder obtener un mapa de inundación que permita identificar las zonas susceptibles a este fenómeno, en el distrito del Milagro, departamento de Amazonas. Para poder realizar el mapa de inundación, se parte del análisis hidrológico que consta de delimitar la cuenca Utcubamba, determinar sus características, mediante el software ArcGis. Previamente, se tendrá que recolectar los registros de precipitación de las diferentes estaciones pluviométricas, donde mediante métodos probabilísticos y pruebas de bondad, y estimando los datos faltantes, se puede obtener los hietogramas de diseño para lograr la obtención de las avenidas máximas (caudales de diseño) para diferentes tiempos en que se va a retornar y que se han propuesto. Para el análisis hidráulico, se necesita realizar visitas a campo, para poder hallar el factor de rugosidad más apropiado para el río, y además para obtener un panorama más amplio sobre el lugar de estudio. Se obtendrán las curvas de nivel y la batimetría, datos fundamentales para el modelamiento y obtención de secciones transversales del río. Para ello, se usará el modelo matemático HEC-RAS. Y así con la intervención de los programas y el análisis propuesto se podrá obtener el mapa de inundación y así dar la alternativa de solución más adecuada al problema que se pueda generar / In this research, the hydrological analysis of the Motupe basin is carried out, and later the hydraulic analysis of the Motupe river, in order to obtain a flood map that allows identifying the areas susceptible to this phenomenon, in the district of Milagro, Amazonas. In order to carry out the flood map, we start from the hydrological analysis that consists of delimiting the Utcubamba basin, determining its characteristics, with the help of the ArcGis program. Previously, the precipitation data from the different rainfall stations will have to be collected, where by means of probabilistic methods and goodness tests, and estimating the missing data, the design hietograms can be obtained in order to obtain the maximum flows (design flows) for different proposed return times. For hydraulic analysis, field visits are required to determine the most appropriate roughness coefficient for the river, and also to obtain a broader view of the study site.,contour lines and bathymetry will be obtained, fundamental data for modeling and obtaining cross sections of the river. For this, the mathematical model HEC-RAS will be used. And thus, with the intervention of the programs and the proposed analysis, it will be possible to obtain the flood map and thus provide the most appropriate alternative solution to the problem that may be generated.

This research investigated hydrologic connectivity, the intricate network of water pathways linking waterbodies, and its implications for biodiversity exchange in floodplains. Chapter 1 provides an exhaustive literature review encompassing factors influencing hydrologic connectivity, assessment approaches, scales, challenges, and management tools. Existing research often focuses on single scales and short-term periods, revealing a need for comprehensive multi-scale and extended temporal analyses. The absence of standardized definitions and methodologies in this field is also considered. Chapter 2 presents an innovative approach quantifying eight key connectivity metrics using remote sensing and GIS within the Lower Mississippi Alluvial Valley (LMAV). This adaptable method assesses connectivity between oxbow lakes and varying stream sizes, revealing spatial variability within the LMAV and enhancing scientific understanding of connectivity dynamics while ensuring portability. This research is crucial for effective ecosystem management and targeted conservation efforts, particularly regarding invasive species like the bigheaded carps (Hypophthalmichthys spp.).
