Soil Moisture Measurement in Heterogeneous Terrain
نویسندگان
چکیده
Reliable soil moisture measurement over large areas is much needed for both hydrologic modelling and remote sensing applications. For collecting such data, portable electronic sensors offer a practical alternative to gravimetric measurements. The conversion of the measured electrical output to soil moisture is nonetheless a non-trivial task as it depends on soil type and temperature. In this study, different calibration approaches of the Stevens Hydraprobe® soil dielectric sensor operating at 50MHz are tested with National Airborne Field Experiment (NAFE) data. The objective is to evaluate the impact of soil type and temperature on the sensor response and test the applicability of a general calibration equation.

متن کاملComparison of ground-based and remotely-sensed surface soil moisture estimates over complex terrain during SMEX04
Comparisons to ground-based surface soil moisture estimates are necessary to evaluate the capability of remote sensors to determine soil moisture and its spatiotemporal variability. Soil moisture can be especially variable in regions of complex terrain which exhibit large variations in vegetation, soil properties and hydrologic conditions. The objective of this study is to evaluate the spatiote...
متن کاملEvaluation of MODIS NDVI and NDWI for vegetation droughtmonitoring using Oklahoma Mesonet soil moisture data
[1] The evaluation of the relationship between satellitederived vegetation indices (normalized difference vegetation index and normalized difference water index) and soil moisture improves our understanding of how these indices respond to soil moisture fluctuations. Soil moisture deficits are ultimately tied to drought stress on plants. The diverse terrain and climate of Oklahoma, the extensive...
متن کاملResearch on Regional Spatial Variability of Soil Moisture Based on GIS
As one of soil dynamics properties, soil moisture content is an important factor of soil fertility which counts for much to crop growth situation and scientific irrigation management. A design plan of regional spatial variation of soil moisture measurement was introduced. Its main job includes the use of differential GPS technology for each sampling points in farmland, collecting data of high-p...
متن کاملEvaluation of the Effect of Pre-processing of the Remotely Sensed Data on the Actual Evapotranspiration, Surface Soil Moisture Mapping by an Approach Using Landsat, DEM and Meteorological Data
A practical approach that combines Landsat TM, DEM and in situ conventional meteorological data to estimate the actual evapotranspiration (ET), and to predict the surface soil moisture content (SSMC) in a heterogeneous terrain was proposed and applied to the Urumqi River Basin, Tianshan, China. The successful application of the proposed approach to this meso-scale watershed was found closely re...
