- | * Generating a Digital Elevation Model. | + | |
- | * Delineation of the catchment area surrounding and in connection to the Heraion of Samos. | + | |
- | * Generating the drainage network of the catchment area including surface water levels and discharge data. | + | |
- | * Generating of sub-catchment areas according to special geomorphic characteristics and special land-use characteristics. | + | |
- | * Identifying the geological composition of the wider area under examination. | + | |
- | * Examining the groundwater aquifer systems underlying the catchment area and beyond it’s borders. | + | |

- | ====== Program of hydrological investigation for Feb-Mar 2017 at Samos ====== | + | |
- | + | ||
- | Since there is no data of discharge for Imbrassos river we should produce our own data. | + | |
- | + | ||
- | I. Imbrassos basin will be devided in sub-basins in order to investigate the influence that sub-basins have upon main basin of Imbrassos. We expect to locate sources within the relevant sub-basins. | + | |
- | + | ||
- | II. Divers will be installed withing the river as well as at positions that we will locate withing the sub-basins of our system. | + | |
- | + | ||
- | III. Four combinations of soil and vegetation will be considered: | + | |
- | + | ||
- | - Marble - Forest | + | |
- | - Schist - Forest | + | |
- | - Marble - Maquis (Macchia) shrub-land | + | |
- | - Schist - Maquis (Macchia) shrub-land | + | |

- | For these 4 standardized cases we will install a metallic plate with a V - cut, along with a pressure sensor. | + | |
- | + | ||
- | IV. In order to measure the velocity of water we can use of deuterium, since the area of Imbrassos mouth is a protected wetlands, under the presidential decree Π.Δ. (ΦΕΚ 229/ | + | |
- | + | ||
- | V. For the first reconnaissance of soil we will make trial hole (Βodenschürfe) and take some probes along. | + | |
- | + | ||
- | VI. A soil map that will correlate to the relevant geological map will be also prepared. | + | |
- | + | ||
- | VII. Land use will be identified/ standardized in correlation with the 4 standards set at point c. On the basis of spectral reflectance/ | + | |

- | ====== Hypothesis on cult in regard to springs existence/ | + | |
- | The location of Heraion had a great abundance of natural springs that have been a point of identification for the site. At some points there has been a drought (more than one drought episodes) that led to the distinction of the springs, since water course changed decisively. However, due to micro-movements of the soil during the centuries some springs re-appeared at the site, a fact that led to the creation of a cult-tradition | + | Konsolidierte Texte können |
