Mapping of waterlogged and salt-affected soils using microwave radiometers

Waterlogging and salinity are two major problems identified in coastal regions. No precise remote sensing techniques are available to map the areas affected by these two factors. In order to study the feasibility of using microwave radiometers, numerical calculations of brightness temperature have been carried out over one- and two-layered models representative of waterlogged and salt-affected areas. The behaviour of brightness temperature shows characteristic values over waterlogged and salt-affected areas. The results presented in this paper show the utility of microwave radiometers in mapping waterlogged and salt-affected areas.
