Soil hydraulic properties, which are basically saturated and unsaturated conductivity water retention characteristics, remarkably control the main hydrological processes in catchments. Thus, adequate parameterization of soils is one most important tasks physically based catchment modeling. To estimate these choice PTFs a model often made without taking runoff characteristics into consideration....

Hydrological and climatic modeling of near-surface water energy fluxes is critically dependent on the availability soil hydraulic parameters. Key among these parameters characteristic curve (SWCC), a function relating content (θ) to matric potential (ψ). The direct measurement SWCC laborious, hence, reported values are spatially sparse usually have only small number data pairs (θ, ψ) per sample...

hydraulic attributes play important role in hydrological studies, soil conservation, designing irrigation and drainage systems, soil conservation, and controlling soil erosion in watersheds. their measurements are very tedious and time consuming and due to high spatial variability, a large number of measurements are required for obtaining reliable values. nowadays, prediction of these attribute...
