Floods = natural disaster. Floods = hazard for human and several animals. The Mediterranean supplies water. The Cevennes block everything. Climatic situation between 8h and 15h. Formation of cloudy cells, break up in point of V, V cells aspirate everything. Most of impacts are centered in south of France. Dispersion of exogenous species. Leaching (lessivage) of garbage dumps, agricultural plastics, chemical liquid-waste, ground erosion? Limit land consolidation (stop the destruction of hedges, talus and ditches). Limit the rain streaming (keep fields under grass in winter, scatter grass between crop). A winegrower of Gard said : "On soil under grass, the rain streaming had began on the 8th September in the evening, and on soil not under grass, it had begun in the afternoon".
