A pesticide runoff event was simulated on two 10 m x 50 m constructed wetlands (one non-vegetated, one vegetated) to evaluate the fate of methyl parathion (MeP) (Penncap-M). Water, sediment, and plant samples were collected at five sites downstream of the inflow for 120 d. Semi-permeable membrane devices (SPMDs) were deployed at each wetland outflow to determine exiting pesticide load. MeP was ...

Systematic conservation planning research has focused on designing systems of conservation areas that efficiently protect a comprehensive and representative set of species and habitats. Recently, there has been an emphasis on improving the adequacy of conservation area design to promote the persistence and future generation of biodiversity. Few studies have explored incorporating ecological and...

Most of the approaches to retrieve surface soil moisture (SSM) by optical and thermal infrared (TIR) spectroscopies are purposed calculate various characteristic bands/indices then establish regression relationship between them in combination with measurement data. However, due combined impact many factors, often shows nonlinearity. Moreover, single temporal image measured data not transplantab...

We determine the soil iron content in a semiarid region of Spain using airborne imaging, field and laboratory based spectroscopy. By assessing the influence of vegetation fractional and fully covered areas are separated for specific analysis each. The derived distribution of soil iron content is spatially discontinuous so spatially discontinuous quality indicators are assigned depending on the ...

Mapping of landslides, quickly providing information about the extent of the affected area and type and grade of damage, is crucial to enable fast crisis response, i.e., to support rescue and humanitarian operations. Most synthetic aperture radar (SAR) data-based landslide detection approaches reported in the literature use change detection techniques, requiring very high resolution (VHR) SAR i...

1  Abstract— A simple approach for correcting the effect of vegetation in the estimation of the surface soil moisture (w S) from L-band passive microwave observations is presented in this study. The approach is based on semi-empirical relationships between soil moisture and the polarized reflectance including the effect of the vegetation optical depth which is parameterized here as a function ...
