Physical Features of Waterbodies from Sierra Nevada, Spain
Description
This dataset was obtained over repeated field-trips to the massif in question and contains the physical parameters of its recognised water-bodies. It therefore defines the general cartography of the area, with data on individual features regarding the geographical coordinates (x, y, z), dimensions (length, width, depth), flooded surface area, stored water volume, shoreline length, as well as the area of associated green fringes and the length of their borders. These data were basically obtained using straightforward techniques, such as GPS, tape measurements and photographic interpretation. The data were then used to define the role of these water-bodies in the hydrology of the massif (https://doi.org/10.3390/hydrology6030059). We also identified the formation patterns of each water-body in their situational context, and the role played by each formation process on the stored water volume (https://doi.org/10.3390/w13040438). Sierra Nevada is considered to be clearly representative of a high mountain Mediterranean environment, where the data collected are essential to define the different habitats of the massif and its evolution. Lack of such data is often a problem and represents challenges for research.

Steps to reproduce
The inventory was carried out through specific visits to each water-body over a long (approx. 18 years) observation period due to difficult access because of snow. Geographical coordinates were obtained using a portable GPS (Garmin eTrex 10) and “Google Earth” and “Iberpix” visors (IGN), as well as the specific features of each formation pattern. Dimensions were measured using metric tape, and water depth was determined using a single seat rubber boat. The cartography of water surfaces and related green fringes was based on orthogonal aerial photographs (detailed images downloaded from Google Earth Pro 7.3.4.8248 (64-bit), Landsat 8), and contrasted with field data, measurements performed with Canvas X Pro software. The database was made as an Excel sheet, where the volumes were determined.
