Europe. A total of 660, 522, and 4940 soil samples belonging to GRIZZLY, HYPRES, EU-HYDI databases, respectively, were used for parametric evaluation. The water retention hydraulic conductivity functions are crucial input information land surface models. Determining these by using direct methods is hampered excessive time unaffordable costs required field activities laboratory analyses. Pedotra...

Clay minerals dominate the soil colloidal fraction and its specific surface area. Differences among clay mineral types significantly influence their effects on hydrological mechanical behavior. Presently, content is used to parameterize hydraulic properties (SHMP) for land models while disregarding type of mineral. This undifferentiated use leads inconsistent parameterization, particularly betw...

The vegetated filter strip model (VFSMOD) was used to investigate the effect of GreenAmpt infiltration parameters (found with different estimation techniques) on sediment and water trapping in vegetated filters of varying soil types. Field-measured and empirically-estimated infiltration parameters were compared. Field saturated hydraulic conductivity (Kk) values were calculated with an inverse ...

To estimate the Cation Exchange Capacity (CEC), indirect manner used of Pedotransfer Functions (PTFs). CEC is one of the important soil fertility factors, and not measured directly because it is costly and time consuming. Thus, used from regression equations between easily and non-easily soil properties. The purpose of this research, is develop the PTFs for CEC, with use of easily available soi...

Pedomodels have become a popular topic in soil science and environmentalresearch. They are predictive functions of certain soil properties based on other easily orcheaply measured properties. The common method for fitting pedomodels is to use classicalregression analysis, based on the assumptions of data crispness and deterministic relationsamong variables. In modeling natural systems such as s...
