Quantifying Groundwater Infiltrations into Subway Lines and Underground Car Parks Using MODFLOW-USG

Tracing and quantifying groundwater inflow into lakes using radon-222

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Due to its high activities in groundwater, the radionuclide 222 Rn is a sensitive natural tracer to detect and quantify groundwater inflow into lakes, provided the comparatively low activities in the lakes can be measured accurately. Here ...

Optimal Selection of Underground Parking Lines Arrangement: A Case Study of Tehran Subway Line 7

Labeling Subway Lines

Graphical features on map, charts, diagrams and graph drawings usually must be annotated with text labels in order to convey their meaning. In this paper we focus on a problem that arises when labeling schematized maps, e.g. for subway networks. We present algorithms for labeling points on a line with axis-parallel rectangular labels of equal height. Our aim is to maximize label size under the ...
