Surface Monitoring. The surface monitoring may be carried out by precision leveling, Total Station surveys, and now-a-days using Differential GPS control surveys within the landslide area. The survey pillars or pedestals of suitable sizes, used as reference or control points, are generally constructed made of reinforced cement concrete. Sometimes, iron/ wooden pegs are also used. The pillars are embedded within the ground with their numbers marked on top. These pillars are Upper slope Upper slope Main scarp

Surface Monitoring. Xxxxxxxx Xxxx, Xxxxxx X. Xxxxxxxxx, and Xxxxxxxx X. Xxxxxxx Alabama A&M University The Alabama A&M University groups and Xxxx Xxxxx of UAB met in Citronelle on June 11 and 12, 2008, to install soil gas monitoring instrumentation near the xxxxx in the CO2 injection test pattern, continue the set-up of vegetation test plots, and measure CO2, other minor gaseous species, and particulate matter in the ambient air. The group was accompanied in the field by Xxxxxx Xxxxxx of Xxxxxxx, who was very knowledgeable regarding field operations and a great help with the set-up and sampling work. Xxxxxx Xxxxxxxxx is focused primarily on measurement of CO2 in soil and the effects it would have on biological activity in the soil. Xxxxxxxx Xxxx and Xxxxxxxx Xxxxxxx are concentrating on the measurement of CO2 in ambient air and the effects of changes in ambient CO2 on plant growth. The group led by Xxxxxx Xxxxxxxxx consisted of Xxxxxx and three of his students: Xxxxxxx Xxxxxxxx, Xxxxxx Xxxxxxxx, and Xxxxxxxxx Xxxxx. Their goal during the visit on June 11-12 was to collect soil samples and set up instrumentation for measurement of soil conditions at points surrounding the injection well and each of the production xxxxx. The instrumentation consists of a soil moisture probe, from which a profile of soil moisture content can be obtained at depths up to 1 m, a soil thermometer placed at a depth of 0.46 m (18 in.), soil gas probes at depths of 0.2, 0.4, 0.6, 0.8, and 1.0 m, and a chamber for capturing gas evolved from soil at the surface. The probes were installed and samples collected at three locations equally spaced around each well, beyond the tree line at the edge of the clearing surrounding the well, as shown in Figure
Surface Monitoring. Xxxxxx Xxxxxxxxx and his students at AAMU have installed sampling xxxxxxxx for measurement of CO2 fluxes from soil, and probes for soil moisture, temperature, and gas composition at three locations surrounding each of the five xxxxx in the test pattern. Xxxxxxxx Xxxx and his coworkers at AAMU have documented the dependence of species richness and species density in Alabama on location and environmental factors, such as latitude, elevation, annual average temperature, precipitation (Xxxx and Xxxx, 2007), and roadless area (Xxxx and Xxxxxxx, 2008). Another paper by Xx. Xxxx (2008) analyzes the spatial distribution of 60 species in 12 families of amphibians using a clustering coefficient that measures the strength of a population group, the statistical distribution of occurrence localities of species, the fractal dimension of occurrence localities, and distances to nearest neighbor. The implications for species conservation of these topological characteristics of the spatial distribution of species are explored and discussed. The state-wide view of species distributions taken by this group will help to discriminate whether any changes observed at Citronelle are associated with local conditions, or with processes occurring on larger spatial scales.
