Hydrogeology

<p>(Image: Illustration of the strata boundary of fresh and salt water in coastal areas)</p><p>Hydrogeology is the study of the behaviour of water in the ground, regardless of whether the physical state of water is solid (ice), liquid (groundwater) or gaseous.</p><p>Hydrogeology also covers the interaction between groundwater and surface water (drainage ditch and bank filtrate).</p><p>Water moves underground usually within the cavities of loose rock, the gaps and joints …</p>

When Is Hydrogeology Useful?
-
<p>In the given case of application, hydrogeological investigations are particularly used to determine the:</p><ul><li>
<p>Groundwater level</p></li>
<li>
<p>Flow velocity and direction</p></li>
<li>
<p>Permeability</p></li>
<li>
<p>Accruing water quantity</p></li>
<li>
<p>Hydrostatic pressure condition</p></li>
<li>
<p>Chemistry of the groundwater</p></li>
</ul><p/>

Why Are Site Specific Hydrogeological Investigations Useful?
-
<p>The knowledge of the site-specific hydrogeological conditions has a significant influence on the selection of the individually appropriate inspection-, construction- or rehabilitation method.</p><p>Furthermore, in conjunction with the in situ soil, conclusions can be drawn with regard to possible water retention measures and their potential consequences, e.g. when creating small building pits for repair measures from outside or when replacing drains and …</p>
