Predicted Infiltration for Sodic/Saline Soils from Reclaimed Coastal Areas: Sensitivity to Model Parameters
This study was conducted to assess the influences of soil surface conditions and initial soil water content on water movement in unsaturated sodic soils of reclaimed coastal areas. Data was collected from column experiments in which two soils from a Chinese coastal area reclaimed in 2007 (Soil A, saline) and 1960 (Soil B, nonsaline) were used, with bulk densities of 1.4 or 1.5 g/cm(3). A 1D-inf...
متن کاملSensitivity analysis: from model parameters to system behaviour.
Sensitivity analysis addresses the manner in which model behaviour depends on model parametrization. Global sensitivity analysis makes use of statistical tools to address system behaviour over a wide range of operating conditions, whereas local sensitivity analysis focuses attention on a specific set of nominal parameter values. This narrow focus allows a complete analytical treatment and strai...
متن کاملReclaimed Areas Mapping by Remotely Sensed Data
In the last decade several mining areas and corresponding dumps are subject to reclamation process in Bulgaria. We focused our research on one of the most important in the copper production for 20 year period for our country – Medet deposit. This mining complex consists of an open cast mine, the overburden dumps and a processing plant. After ceasing its exploitation in 1994 a rehabilitation pro...
متن کاملSorption of organic compounds to humin from soils irrigated with reclaimed wastewater
Article history: Received 17 October 2007 Received in revised form 11 February 2008 Accepted 26 February 2008 Available online 14 April 2008 Humin is an important fraction of soil organic matter that is known to tightly bind many organic compounds. The objective of this study was to evaluate the role of humin as a natural sorbent in soils irrigated with freshwater and treated wastewater. To mee...
متن کاملMonte Carlo sensitivity analysis of land surface parameters using the Variable Infiltration Capacity model
[1] Current land surface models use increasingly complex descriptions of the processes that they represent. Increase in complexity is accompanied by an increase in the number of model parameters, many of which cannot be measured directly at large spatial scales. A Monte Carlo framework was used to evaluate the sensitivity and identifiability of ten parameters controlling surface and subsurface ...
