in this study, hydrus2d/3d software was used to estimate the hydraulic parameters of van genuchten-mualem model via inverse modeling using double-ring infiltrometers data in 3 different soil textures. nine scenarios of inverse modeling (divided in three groups) were considered with different number (5, 4 and 3) of fitted hydraulic parameters for optimization. in the first group, simulation was ...
is often still limited by the ill-posedness of the problem being considered. Ill-posedness in general is affected Inverse methods are increasingly used to estimate the hydraulic by nonoptimal experimental design, poor measurement properties of unsaturated soils. The method generally uses a weighted least-squares approach in which numerically simulated data are fitted quality, errors in the assu...
Microwave remote sensing techniques provide a direct measurement of surface soil moisture (SM), with advantages for all-weather observations and solid physics. However, most satellite microwave products fail to meet the requirements land studies high-resolution data due their coarse spatial resolutions. Although many approaches have been proposed downscale resolution products, them tested in fl...
Soil tillage changes chemical and physical properties which can change the soil available water capacity. For understanding the effect of soil disturbance in cultivated soil on available water, parameter pedotransfer functions of these soils created and their results were compared with measured available water by moisture release curves. For this purpose 54 soil samples were taken from cultiva...
Cosmic-Ray Neutron Sensing (CRNS) offers a non-invasive method for estimating soil moisture at the field scale, in our case few tens of hectares. The current study uses Ensemble Adjustment Kalman Filter (EAKF) to assimilate neutron counts observed four locations within 655 km 2 pre-alpine river catchment into Noah-MP land surface model (LSM) improve simulations and optimize parameters. runs wit...
Abstract Most biogeochemical models simulate water dynamics using the tipping bucket approach, which has been often found to be too simplistic represent vadose zone adequately under shallow groundwater conditions. Recently, a solution Richards equation Mualem–van Genuchten model (Rich‐vGM) added into EPIC (Environmental Policy Integrated Climate) address this shortfall. Its performance was test...
