“…Winter et al (2008) and Tiedeman et al (1998) monitored 31 bedrock wells and found water table gradients caused by different geological units within a catchment. Even in headwater catchments, variability in groundwater dynamics has been found due to multiple underlying aquifers (Kosugi et al, 2008(Kosugi et al, , 2011.…”

Abstract. Hydrological processes, including runoff generation, depend on the distribution of water in a catchment, which varies in space and time. This paper presents experimental results from a headwater research catchment in New Zealand, where we made distributed measurements of streamflow, soil moisture and groundwater levels, sampling across a range of aspects, hillslope positions, distances from stream and depths. Our aim was to assess the controls, types and implications of spatial and temporal variability in soil moisture and groundwater tables.We found that temporal variability in soil moisture and water table is strongly controlled by the seasonal cycle in potential evapotranspiration, for both the mean and extremes of their distributions. Groundwater is a larger water storage component than soil moisture, and this general difference increases even more with increasing catchment wetness. The spatial standard deviation of both soil moisture and groundwater is larger in winter than in summer. It peaks during rainfall events due to partial saturation of the catchment, and also rises in spring as different locations dry out at different rates. The most important controls on spatial variability in storage are aspect and distance from the stream. South-facing and near-stream locations have higher water tables and showed soil moisture responses for more events. Typical hydrological models do not explicitly account for aspect, but our results suggest that it is an important factor in hillslope runoff generation.Co-measurement of soil moisture and water table level allowed us to identify relationships between the two. Locations where water tables peaked closer to the surface had consistently wetter soils and higher water tables. These wetter sites were the same across seasons. However, patterns of strong soil moisture responses to summer storms did not correspond to the wetter sites.Total catchment spatial variability is composed of multiple variability sources, and the dominant type is sensitive to those stores that are close to a threshold such as field capacity or saturation. Therefore, we classified spatial variability as "summer mode" or "winter mode". In "summer mode", variability is controlled by shallow processes, e.g. interaction of water with soils and vegetation. In "winter mode", variability is controlled by deeper processes, e.g. groundwater movement and bypass flow. Double streamflow peaks observed during some events show the direct impact of groundwater variability on runoff generation. Our results suggest that emergent catchment behaviour depends on the combination of these multiple, time varying components of storage variability.

This study presents an approach for delineating groundwater basins and estimating rates of recharge to fractured crystalline bedrock. It entailed the use of completion report data (boring logs) from 2500 domestic wells in bedrock from the Coventry Quadrangle, which is located in northeastern Connecticut and characterized by metamorphic gneiss and schist. Completion report data were digitized and imported into ArcGIS(®) for data analysis. The data were processed to delineate groundwater drainage basins for the fractured rock based on flow conditions and to estimate groundwater recharge to the bedrock. Results indicate that drainage basins derived from surface topography, in general, may not correspond with bedrock drainage basins due to scale. Estimates of recharge to the bedrock for the study area indicate that only a small fraction of the precipitation or the amount of water that enters the overburden recharges the rock. The approach presented here can be a useful method for water resource-related assessments that involve fractured rock aquifers.

“…Tiedman et al (1998) definem bacia hidrogeológica como os limites e caminhos que a água subsuperficial segue através do aqüífero, desde as zonas de recarga até um exutório específico. Segundo a resolução Número 15, do Conselho Nacional de Recursos Hídricos (CNRH 2001), um corpo hídrico subterrâneo corresponde ao volume de água armazenado no subsolo, onde os aqüíferos podem apresentar zonas de descarga e recarga pertencentes a uma ou mais bacias hidrográficas sobrejacentes.…”

Resumo A designação de "bacia hidrogeológica" ainda necessita ser complementada com relação aos aspectos de sua conceituação e aplicação. Um dos enfoques desprovidos de embasamento teórico e conceitual diz respeito aos critérios para definição dos limites das bacias hidrogeológicas e as relações com as bacias hidrográficas sobrepostas. A literatura técnica atualmente disponível a esse respeito é muito restrita e incompleta. Assim o objetivo do presente trabalho é contribuir com o conhecimento sobre as bacias hidrogeológicas, bem como caracterizar uma terminologia a ser utilizada para futuros estudos hidrogeológicos em áreas específicas. Dentre as principais técnicas aplicadas à delimitação das bacias hidrogeológicas destacam-se os estudos de piezometria, hidrologia, hidroquímica, ensaios de traçadores e geofísica, e, dentre suas principais aplicações e implicações podem ser citadas a gestão integrada dos recursos hídricos, o estudo de aqüíferos transfronteiriços, a definição do perímetro de proteção dos poços e o estudo de remediação de aqüíferos contaminados.Palavras-chave: bacias hidrográficas, bacias hidrogeológicas/subterrâneas, delimitação, gestão. Abstract Criteria to the determination and evaluation of hydrogeologic basinThe designation of the "hydrogeologic basin" terminology still needs to be complemented regarding the definition and application aspects. One of the approaches without theoretical and conceptual basement is related to the criteria for definition the boundaries of the hydrogeologic basins and the relationships with the overland watersheds. The available technical literature is very restricted and incomplete. Because of this, the objective of the present paper is to contribute with the knowledge on the hydrogeologic basins, as well as to characterize a terminology to be used for futures hydrogeologic studies. Potenciometric surfaces mapping, hydrology, hidrochemistry, tracing tests and geophysics are among the main applied techniques to the delimitation of the hydrogeologic basins. The integrated wate resource management, the study of borders aquifers, the definition of well protection perimeter and the remediation study on polluted aquifers are some of the cases where the knowledge of the hydrogeologic boundaries is very important.Keywords: watershed, hydrogeologic/groundwater basin, delimitation, management.1 -Instituto Geociências, Universidade de Brasília, Brasília, DF.

E-mail: eloi@unb.br INTRODUÇÃO Em estudos hidrológicos e de demais fenômenos do fluxo superficial, a unidade principal de investigação é a bacia hidrográfica (Rennó 2004). Dessa forma, muitos dos critérios utilizados para a delimitação da unidade hidrográfica são bem conhecidos e contam inclusive com modelos digitais já desenvolvidos que permitem, a partir da existência de curvas de nível, a delimitação automática das bacias e do sentido do escoamento superficial em qualquer ponto da poligonal da bacia (Rennó & Soares 2001)....
