“…The relative significances of the criteria are evaluated on a scale of 1-9, indicating less importance to greater importance. Weighting by AHP is widely used in many applications [40,41] and it is recommended to be used for regional studies. The steps of the AHP for weighting are as follows:…”

This study focused on landslide susceptibility analysis mapping of the Xulong hydropower station reservoir, which is located in the upstream of Jinsha River, a rapidly uplifting region of the Tibetan Plateau region. Nine factors were employed as landslide conditioning factors in landslide susceptibility mapping. These factors included the slope angle, slope aspect, curvature, geology, distance-to-fault, distance-to-river, vegetation, bedrock uplift and annual precipitation. The rapid bedrock uplift factor was represented by the slope angle. The eight factors were processed with the information content model. Since this area has a significant vertical distribution law of precipitation, the annual precipitation factor was analyzed separately. The analytic hierarchy process weighting method was used to calculate the weights of nine factors. Thus, this study proposed a component approach to combine the normalized eight-factor results with the normalized annual precipitation distribution results. Subsequently, the results were plotted in geographic information system (GIS) and a landslide susceptibility map was produced. The evaluation accuracy analysis method was used as a validation approach. The landslide susceptibility classes were divided into four classes, including low, moderate, high and very high. The results show that the four susceptibility class ratios are 12.9%, 35.06%, 34.11%and 17.92% of the study area, respectively. The red belt in the high elevation area represents the very high susceptibility zones, which followed the vertical distribution law of precipitation. The prediction accuracy was 85.74%, which meant that the susceptibility map was confirmed to be reliable and reasonable. This susceptibility map may contribute to averting the landslide risk in the future construction of the Xulong hydropower station.

“…A avaliação e modelagem destes recursos têm sido feita com sucesso desde a década de 1970, porém, atualmente, o uso de recursos digitais, conjuntamente à análise geoespacial, tem permitido um melhor tratamento e espacialização de dados (FETTER, 1994;FEITOSA, 2008, OH et al, 2011ABDALLA, 2012;ELBEIH, 2015;OIKONOMIDIS, 2015;RAHMATI et al, 2016).…”

“…Na maioria dos casos, os parâmetros são estabelecidos a partir da correlação entre a produtividade dos poços com distintas configurações da paisagem. Assim, os principais métodos conceituais utilizam caraterísticas que favoreçam a porosidade secundária ou primária, como litotipos, lineamentos e morfoestruturas, zonas de juntas e de camadas, dissecação do relevo, pedologia, vegetação e manto de intemperismo, entre outras, para avaliar a favorabilidade (SMERDON et al, 2009;SOUZA FILHO et al, 2010;OH et al, 2011;OIKONOMIDIS, 2015).…”

Resumo: Este artigo trata do mapeamento da favorabilidade hidrogeológica em aquíferos fraturados, na região do Circuito das Águas Paulista. As técnicas de sensoriamento remoto e análise geoespacial foram utilizadas para criação e combinação de mapas geológico, fisiográficos, estrutural, de uso e cobertura do solo e de favorabilidade. Estes dados foram manipulados em sistemas de informação geográfica, visando ao mapeamento da favorabilidade hidrogeológica, utilizando lógica Fuzzy. O mapeamento de favorabilidade se mostrou de acordo com os valores de capacidade específica, e com o padrão de distribuição dos poços. Além disso, a superfície de tendência gerada a partir dos dados de capacidade específica se mostrou em conformidade com o mapa de favorabilidade, corroborando a acurácia do método utilizado e demonstrando uma alta favorabilidade hidrogeológica nos municípios e Águas de Lindóia de Lindóia.Palavras Chaves: Lógica Fuzzy. Análise Geoespacial. Potencial hidrogeológico. Circuito das Águas Paulista.Abstract: This article deals with the mapping of hydrogeological favorability in fractured aquifers, in the so called Circuito das Águas Paulista. Remote sensing and geospatial analysis techniques were used to create and combine geological, physiographic, structural, land cover, and favorability maps. These data were manipulated in geographic information systems, aiming the mapping of hydrogeological favorability, using Fuzzy logic. The favorability mapping was shown according to the specific capacity values and to the distribution pattern of the wells. In addition, the trend surface generated from the specific capacity data was in accordance with the favorability map, corroborating the accuracy of the applied method, showing a high hydrogeological favorability in the Águas de Lindóia and Lindóia municipalities.

Abstract:The Mezquital Valley (MV) hosts the largest unmanaged aquifer recharge scheme in the world. The metropolitan area of Mexico City discharges~60 m 3 /s of raw wastewater into the valley, a substantial share of which infiltrates into the regional aquifer. In this work, we aim to develop a comprehensive approach, adapted from oil and gas reservoir modeling frameworks, to assess water supply sources located downgradient from unmanaged aquifer recharge zones. The methodology is demonstrated through its application to the Mezquital Valley region. Geological, geoelectrical, petrophysical and hydraulic information is combined into a 3D subsurface model and used to evaluate downgradient supply sources. Although hydrogeochemical variables are yet to be assessed, outcomes suggest that the newly-found groundwater sources may provide a long-term solution for water supply. Piezometric analyses based on 25-year records suggest that the MV is close to steady-state conditions. Thus, unmanaged recharge seems to have been regulating the groundwater balance for the last decades. The transition from unmanaged to managed recharge is expected to provide benefits to the MV inhabitants. It will also be likely to generate new uncertainties in relation to aquifer dynamics and downgradient systems.
