Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>Water tracing means ‘tagging’ water, usually by adding a colour or dye, to see where it goes. Dye is usually added to a sinking stream and all possible outlet points (such as springs and rivers) are tested for the dye.</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN /><SPAN /></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>Water traces are recorded as a straight line between the location of tracer input (e.g. swallow hole) and detection (e.g. spring), but they don</SPAN></SPAN><SPAN><SPAN>’</SPAN></SPAN><SPAN><SPAN>t show the actual path water may take underground, which is likely to be much more winding</SPAN></SPAN><SPAN><SPAN>.</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>It is mainly used in karst areas to find out groundwater flow rates, the direction the water is travelling underground and to help define catchments (Zone of Contributions).</SPAN></SPAN><SPAN /></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>The dataset should be used alongside the Karst Landforms 1:40,000 Ireland (ROI/NI) ITM.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>Geologists map and record information in the field.
