Evaluating Preventive Measures for Flooding from Groundwater: A Case Study

Groundwater (GW) flooding mechanisms differ from river flooding, both spatially and temporally, preventative methods against groundwater must take this into account. Although caused by a rise of water seldom occurs, it can occasionally become severe last for long time if the is significantly flooded. In southwest portion research domain, Friedrichshafen, Germany, with few urban communities, level table was discovered to be roughly 1 m below surface. study region, typical bottom foundation single-story building extend up depth about 1.5 m. Therefore, flood mitigation are taken account region. study, FEFLOW used explore increase in settings, spread contamination, strategizing effective solutions flooding. The installation pumping well, drainage, barrier affected area three different control strategies that consideration area. Pumping well installation, reducing hydraulic head, found most measure locally small By contrast, removing drainage barriers shown ineffective lowering over an extended more expensive than wells. Additionally, when account, compared default scenario where no intake included along western border area, pollution (nitrate concentration) greater.
