A new chloride leaching approach to the estimation of diffuse recharge following a change in land use

摘要: Abstract A new approach has been developed to estimate the increase in groundwater recharge following land-use modification. The uses degree of leaching chloride quantify soilwater drainage below root zone which ultimately leads recharge. It is more general than similar previously reported techniques for analysing transient profiles infer rates, and hence wider application. We have applied technique a field situation southern Australia where clearing native vegetation agricultural production large increases examples serve demonstrate some practical difficulties application solutes estimation.
