Vadose Zone Hydrology and Groundwater Recharge

摘要: The rate of recharge (i.e., renewal) groundwater is a key factor regulating sustainable use resources. Hydrological processes in the vadose zone have two important roles: one to partition precipitation input into and evapotranspiration, other damp down temporal variability flux. Infiltration first process after controlled by atmospheric (e.g., rainfall intensity) soil conditions infiltration capacity). Bare evaporation transpiration are loss infiltrated water. bare sensitive moisture status surface soils as well conditions. Transpiration not very these capable taking up water from deeper depths. spatial characteristics change drastically depending on climatic humid or arid). Climate human activity can affect variation pattern recharge. Proper understanding hydrology fundamentally increasing improving our knowledge for wise during changes climate society.
