There is no doubt about the need to replace the textural triangle by the cumulative particle – size distribution curves in the research context of Albanian soils. Beside all, it creates the necessary space to establish the relationships between the cumulative particle – size distribution curves and the most important hydraulic properties of soils. Therefore, having the cumulative particle – size distribution curve belonging to a specific soil, it becomes possible the recognition of hydraulic properties of this very soil. There are many efforts to determine the best fit equation reflecting the cumulative particle – size distribution curves. However, the best fit in our research seems to be exponential law function in its closed form. This conclusion became possible to be drawn based on a considerable large textural data base collected throughout the soils of Albania. Whether this conclusion is true for the soils where the clay predominates, or silt and sand predominate; or whether it has the same significance as for fitting to the process of data transfer from one scheme to another, it requires further research.
Keywords: cumulative particle – size distribution curve; exponential law function; textural triangle.
