With the groundwater conditions improved, migratory birds returned to the lake in big numbers.

As the determination of groundwater conditions is important - the use of piezometers are at times used.

Pumping allows the determination of groundwater conditions using pumping and observation wells.

Previous research concentrated on the removal of nitrate that was observed when groundwater conditions change from aerobic to anaerobic.

The purpose of this sampling was to collect data to assess groundwater conditions and evaluate potential threats to human health and the environment.

Groundwater conditions.

Earthquake effects, external loading, groundwater conditions, stabilization forces (i.e. anchors, georeinforcements etc.) can be also included.

Geological and groundwater conditions made construction of deep ouvrages of the kind found in the main Line difficult in the Maubeuge area.

Two-dimensional models apply to a vertical plane while it is assumed that the groundwater conditions repeat themselves in other parallel vertical planes (Fig. 4).

Values are for typical fresh groundwater conditions - using standard values of viscosity and specific gravity for water at 20 C and 1 atm.

Unpredictable impact of the leaching liquid on the rock of the deposit, and the impossibility of restoring natural groundwater conditions after completion of the leaching operations.

In high groundwater conditions a perforated plastic (PVC or PE) pipe is laid along the base of the drain to increase the volume of water transported in the drain.

The development of granular iron PRB technology was reliant on two advances: that metallic irons breaks down chlorinated organic compounds, and that reactions can proceed in situ under normal groundwater conditions.

The semi arid conditions of the area, saline and alkaline soils/groundwater conditions and weathering of the silicate rock exposed in the drainage basin are assessed as the reasons for the supply of major ions.

Successful design of the slope requires geological information and site characteristics, e.g. properties of soil/rock mass, slope geometry, groundwater conditions, alternation of materials by faulting, joint or discontinuity systems, movements and tension in joints, earthquake activity etc.

To this day, the area remains relatively undeveloped - besides being unsuitable for farming, the hard igneous rock, nonporous clay soils, steep slopes and perched wetlands create groundwater conditions which make the area difficult for drilling wells and installing septic systems.

The regional geology and seismology setting is first examined for sources and patterns of earthquake occurrence, both in depth and at the at the surface from seismometer records; secondly, the impacts from these sources are assessed relative to local geologic rock and soil types, slope angle and groundwater conditions.
