BERLIN (AP) — German officials are defending their preparations for flooding in the face of the raging torrents last week that caught many people by surprise and left over 190 people dead in Western Europe. But they concede that they will need to learn lessons from the disaster. Efforts to find any more victims and clean up the mess left behind by the floods across a swath of western Germany, eastern Belgium and the Netherlands continued on Monday as floodwaters receded. The downpours that led to usually small rivers swelling at vast speed in the middle of last week had been forecast, but warnings of potentially catastrophic damage didn’t appear to have found their way to many on the ground.
