“…Excepting the Canary Islands model, the 374 km 2 Mayotte case study is probably not as unusual as formerly assumed. It appears to be similar to a study of a 200 km 2 region on the Pliocene basaltic Kauai Island (Hawaii), which is also characterized by a generally low K (Izuka and Gingerich, ) explained by the ‘ filling‐up of the Lihue basin depression with hundreds of metres of sediment as well as with lava flows from rejuvenated volcanism ’. Here again, a more precise geological description might result in a conceptual model with similar determinisms to the Mayotte one.…”

International audienceWe present a high-resolution conceptual hydrogeological model for complex basaltic volcanic islands based on Mayotte Island in the Comoros. Its geological structure and hydrogeological functioning are deduced from a large dataset: geological mapping, geophysics, some forty new boreholes, piezometric data, hydraulic conductivity, hydrochemical data, etc. We describe previously unknown deep cut-and-fill palaeovalleys. The resulting conceptual geological and hydrogeological model of the island is very different from the Hawaiian model, in that it lacks a low-elevation basal aquifer and dyke-impounded high-level aquifers. It is closer to the Canary Islands model, which has, however, not yet been described at a high-resolution scale. It does not have a continuous aquifer, but rather a discontinuous succession of perched aquifers separated by aquicludes and aquitards. This results more from the complex geological structure of the island, which has experienced several phases of volcanism, erosion and weathering, than from its age, but is also a result of the high-resolution scale of the model. High-resolution conceptual modelling is now necessary to solve problems of applied geology and hydrogeology

“…Ingebritsen and Scholl (1993) reported much lower hydraulic conductivity for deeply buried (>1 km) basalts of the Kilauea volcanic rift zone on Hawaii compared to surficial basalt flows, attributed to either pervasive intrusion of less-permeable dikes and (or) hydrothermal alteration. Saturated hydraulic conductivity values about 1-4 orders of magnitude less than shield building-stage basaltic aquifers were reported for postshield and rejuvenated-stage basin-filling basalts of the southern Lihue Basin on the island of Kauai, Hawaii (Gingerich, 1999;Izuka and Gingerich, 2003). For the Teide Volcano of Tenerife (Canary Islands), a high degree of anisotropy is due to shield volcano layering and alternation of low permeability non-fractured dikeintruded basalts with more permeable fractured basalts (Valentin et al, 1990).…”

“…Examples include dike impounded groundwater in the Koolau Volcano rift zone on the island of Oahu (Takasaki and Mink, 1985;Oki, 2005) and in the interior of West Maui Mountain (Engott and Vana, 2007). While high-altitude regional water tables are typically associated with dike-impounded conditions, a regional water table in the Lihue Basin of Kauai occurs hundreds of meters above sea level within a few kilometers of the coast, attributed to thick low-permeability basalts (Izuka and Gingerich, 2003).…”

“…Young lavas are extremely permeable (Saar and Manga, 2004), and recharge areas and flow paths are controlled mainly by the geographic extent of lava flows (Kiernan et al, 2003;Jefferson et al, 2006). Izuka and Gingerich (2003) reported that volcanic dikes and lower-permeability strata compartmentalize groundwater flow. The scale of the groundwater flow decreases with increasing age of the volcanic body, a phenomenon related to erosion of the volcanic body (e.g.…”

Groundwater movements in volcanic mountains and their effects on streamflow discharge and representative elementary area (REA) have remained largely unclear. We surveyed the discharge and chemical composition of spring and stream water in two catchments: the Hontani river (NR) catchment (6.6 km2) and the Hosotani river (SR) catchment (4.0 km2) at the southern part of Daisen volcano, Japan. Daisen volcano is a young volcano (17 × 103 years) at an early stage of erosion. Our study indicated that deep groundwater that moved through thick lava and pyroclastic flows and that could not be explained by shallow movements controlled by surface topography contributed dominantly to streamflow at larger catchment areas. At the NR catchment, the deep groundwater contribution clearly increased at a catchment boundary defined by an area of 3.0 km2 and an elevation of 800 m. At the SR catchment, the contribution deep groundwater to the stream also increased suddenly at a boundary threshold of 2.0 and 700 m. Beyond these thresholds, the contributions of deep bedrock groundwater remained constant, indicating that the REA is between 2 and 3 km2 at the observed area. These results indicate that the hydrological conditions of base flow were controlled mainly by the deep bedrock groundwater that moved through thick lava and pyroclastic flows in the undissected volcanic body of the upper part of the catchment. Our study demonstrates that deep and long groundwater movements via a deep bedrock layer including thick deposits of volcanic materials at the two catchments on Daisen volcano strongly determined streamflow discharge instead of the mixing of small‐scale hydrological conditions.
