Analysis of flood impacts on masonry structures and mitigation measures

The impact of floods can be devastating to buildings, especially in countries and villages in mountainous areas. Based on the flood impact risk analysis results, two methods are suggested by authors to improve the flood impact defense capability of rural buildings in this paper: increasing the stren...
