After that it is pointed out that compared with soil density changes, water content change can result in more variations of coefficient of thermal conductivity and specific volume heat of loess.
First, soil erosion modulus can be estimated by using water erosion model, and the maps of soil density and soil horizon thickness can be derived from soil detailed survey data.
