Electrical imaging is an appropriate follow-up method for the investigation of electrical conductivity anomalies first identified by EM profiling and is advisable before drilling at a site to optimise the location of piezometers
For creating tracks,- For the creation of sewage treatment plants,- To ensure stability of the dike,- For coring and qualitative analysis of the particle size layers including river bed,- For the establishment of piezometers
The height of the perched watertable above the B horizon was monitored by piezometers
installed to a depth of approximately 0.
Whereas the behaviour of the deep aquifer can only be studied using usually widely spaced, deep piezometers
, computer models can interpolate between piezometers
and can be used, with the appropriate validation and precautions, where there are no piezometers
are used to monitor pore-water pressure in the borehole.
firm TF) (5 and core drilling in conditional phase) (TC01 - the identification of the nature of the materials encountered in reconnaissance surveys: naturally occurring material in place, polluted materials historic dairy (), pavement structure materials (diverse embankments, top layer of floor, milled asphalt), - analysis of available data on prior recognition campaigns - estimating the volume of each type of material generated by the deconstruction of the current RN90 site, - laying two piezometers
The implementation of the contract includes the following elements for 3 (three) years: For tailing" Mechi dol " : Restoration work in instrumentation system and collectors in the western gully upper diversion dike - building 5 pieces piezometers
Study stability of slopes of tailings Assessment and inspection of the condition of the pond Clean the exterior drainage system Observations and chemical analyzes of drainage water
The settelements of the landslide area were regularly monitored by levelling of markers buried on the site area; the fluctuation of the watertable was carried out by monitoring the response of standpipe piezometers
installed on the site.
were inserted into the sediments and epilithic algal samples were collected from the main channel of a large alluvial river in northwestern Montana during June, July, and August 2004 to test the null hypotheses that there are no differences in epilithic algal biomass and community composition between sites of hyporheic upwelling, surface water downwelling, and no hyporhiec-surface water connectivity.
The crew installed erosion-control silt fences and brush barriers around the perimeter of the slide and installed temporary piezometers
to measure the water pressure and inclinometers to monitor the slope for movement during construction.
were manually installed to a maximum depth of 3 meters within the floodplain region and in the Heron Pond at the intersection points of surveyed hectares.
Invitation to tender: drilling of four piezometers
