a methodology of soil moisture assessment around a levee based on a backpropagation neural network and using Synthetic Aperture Radar (SAR) data is developed. Soil moisture changes along a levee over a period of time can help to monitor and find potential failure indicators such as slides and sand boils around the levee. Several analytical and empirical models have shown relationships between S...

Background: Irrigation performs a substantial function for the growth of Agricultural vegetation. Soil supplies essential nutrients plant and provides anchor support to roots crops. Moisture permits requirement water system be measured ahead yield giving indications misery. Knowing soil moisture status empowers exceptionally productive system, as when required wiping out inefficient utilization...

A dynamical forecast model is applied to study thlJ moisture variation in the planetary boundary layer under the chosen synoptic condition. The observed l2-hour moisture patterns are compa.red with the forecast patterns. Four numerical experiments, using the same initial data on 0600 CST, March 25, 1967, are made. However, in one case only the effects of evaporation from the Gulf of Mexico, and...
