Abstract Soil moisture (SM) is a key hydrologic state variable that of significant importance for numerous Earth and environmental science applications directly impact the global environment human society. Potential include, but are not limited to, forecasting weather climate variability; prediction monitoring drought conditions; management allocation water resources; agricultural plant production alleviation famine; prevention natural disasters such as wild fires, landslides, floods, dust...
Information about the soil–water retention curve is necessary for modeling water flow and solute transport processes in soils. Soil spectroscopy visible, near-infrared, shortwave infrared (Vis-NIR-SWIR) range has been widely used as a rapid, cost-effective nondestructive technique to predict soil properties. However, less attention paid hydraulic properties using spectral data. In this paper, reflectances of samples from Zanjanrood watershed, Iran, were measured Vis-NIR-SWIR ranges (350–2500...
In this study, we developed spectrotransfer functions (STFs) that relate soil hydraulic properties (SHPs) to spectral reflectance values estimate parameters of the Mualem–van Genuchten (MvG) model. We investigated general potential airborne as well space‐borne remote sensors retrieve MvG a bare agricultural field. Based on ASD full spectrum (Scenario I), simple signatures were generated mimicking hyperspectral EnMAP sensor II), and multispectral Sentinel‐2 III). A stepwise multiple linear...
The recently developed OPtical TRapezoid Model (OPTRAM) has been successfully applied for watershed scale soil moisture (SM) estimation based on remotely-sensed shortwave infrared (SWIR) transformed reflectance (TRSWIR) and the normalized difference vegetation index (NDVI). This study is aimed at evaluation of OPTRAM field precision agriculture applications using ultrahigh spatial resolution optical observations obtained with one world’s largest robotic phenotyping scanners located in...
Accurate knowledge of surface and subsurface soil moisture (SM) is essential for hydrologic modeling, weather forecasting, agricultural water management. NASA’s Soil Moisture Active Passive (SMAP) satellite (level 3) provides ‘surface’ SM with 2–3 days temporal resolution, hence lacks daily information. This study developed a convolutional neural network–long short-term memory (ConvLSTM) deep learning model to produce ‘daily’ (5 cm) (25 products (9 km) by integrating SMAP level 3 ancillary...
The reference area (RA) approach has been frequently used in soil surveying and mapping projects, since it allows for reduced costs. However, a crucial point using this is the choice or delineation of an RA, which can compromise accuracy prediction models. In study, innovative algorithm that delineates RA (autoRA—automatic areas) presented, its efficiency evaluated Sátiro Dias, Bahia, Brazil. autoRA integrates multiple environmental covariates (e.g., geomorphology, geology, digital elevation...
Digital Soil Mapping (DSM) enhances the delivery of soil information but typically requires costly and extensive field data to develop accurate prediction models. The Reference Area (RA) approach can reduce sampling intensity; however, its subjective delineation may compromise model accuracy when predicting properties. In this study, we introduce autoRA algorithm, an innovative automated design method that utilizes Gower’s Dissimilarity Index delineate RAs automatically. This preserves...
Core Ideas A TDR array has been developed for soil moisture profiling. The sensor provides eight incremental measurements at centimeter‐depth resolution. Permittivity, evaporation rate, and profile were determined. Near‐surface conditions (i.e., temperature) moderate mass energy exchange the soil–atmosphere interface. While remote sensing offers an effective means mapping near‐surface content across large areas, in situ measurements, targeting those specific remotely sensed depths, are...
Abstract In-depth knowledge about the global patterns and dynamics of land surface net water flux (NWF) is essential for quantification depletion recharge groundwater resources. Net cannot be directly measured, its estimates as a residual individual components often suffer from mass conservation errors due to accumulated systematic biases fluxes.

Saline playas in arid and semiarid regions of the world are significant sources unconsolidated sediments susceptible to aeolian transport. Lake Urmia Iran, one largest saltwater lakes on Earth, has waned approximately 18% its original size due groundwater pumping surface water diversions. This led ecosystem degradation, accelerated desertification frequent dust storms, causing public health problems. In this paper we introduce a new framework for delineation source zones estimation...
Osmotic adjustment (OA) is a major component of drought resistance in crops. The genetic basis OA wheat and other crops remains largely unknown.
