“…However, it is necessary to evaluate data from a time series that encompasses all 57 years of records and every month of the rainy season, which is from April to October, to verify if there is any trend in precipitation behavior. Evaluation of trends in time series, such as rainfall, is an important elemenet in hydrologic evaluations, including geomorphology elements [18,19] and planning efforts to avoid water shortages.…”

Abstract:The Federal District is a politically and economically important part of Brazil, which suffers from water stress. Exploratory analyzes were conducted using data on rainfall in the Federal District from the monthly precipitation time series to assess the rainfall variability in January, a month that falls in the middle of the rainy season in the region. A time series of 30 years , recorded at 19 rain gauges was analyzed. The resulting exploratory analyses show a gradient of increasing rainfall in the westward direction in the Federal District. Moreover, the time series shows a moderate inter-annual variability in rainfall volume, which is, however, of a stationary nature.

In order to assess the geodiversity of the Italian Peninsula, which covers approximately 300.000 km2, a semi-quantitative method based on the use of grids recording several indicators and indices was developed. The variety of geological, geomorphological, and pedological elements, characterizing the Italian territory, has been assessed with a two-step procedure. Firstly, the variety algorithm has been applied using grid cells with variable size, related to the spatial resolution of the input data, then the resulting variety values were averaged with a fixed cell size functional to the extent of the study area and the output scale of the geodiversity map. This procedure made it possible to preserve the spatial resolution of the input data (Digital Terrain Model, lithological and soil maps) providing as output a geodiversity map that faithfully reproduces the features of the Italian territory. In case of discrete data (rivers, lakes, glaciers, etc.), a procedure that assigns to each cell the maximum area or length values out of all its elements has been implemented. It made possible to preserve the hydrological elements that shape the landscape (e.g., the longest rivers, largest lakes, etc.) and represent important freshwater resource. An overview of the geographical distribution of geodiversity classes over the whole Italian territory has been elaborated. The resulting geodiversity map is a valuable tool for environmental planning, in particular for the identification of areas to be preserved, for the proper management of geo-resources and natural services.
