Abstract :
Knowing the temporal features of soil moisture dynamics is essential for proper water resource management, fertilization management, and crop production. This paper proposes a recurrent dynamic learning neural network (RDLNN) to estimate soil moisture evolution by rainfall forcing. Long-term measurements of rainfall and soil moisture content were gathered. Soil moisture contents estimated from daily and/or hourly precipitation by RDLNN, were compared with ground measurements. Experimental results suggested that RDLNN is a promising tool for estimating soil moisture from hourly precipitation.
