Isotopic variations of soil and input water mixing

Soil is a complex system. It is important to study isotopic variations in input water in soil system for water movement mechanism and hydrograph separation. Mechanisms causing isotopic variations and time for reaching isotopic balance between different soil water and input water are studied through soil water mixing experiments. Experimental results show that isotopic variations in mixing water are mainly caused by isotopic mixing between soil water and input water. It is rather difficult to obs...
