| Abstract | Jiangjia Ravine is a world-famous debris flow valley in Dongchuan, Yunnan Province, China. Every year large numbers of landslides and collapses happened and caused enormous damages to people’s properties and lives. With longtime observation and testing in Jiangjia Ravine we had found out one kind of special landslide which had the characteristics of landslide and collapse. Landslide and collapse supplied sufficient materials for debris flow. When a debris flow broke out, some kind of intergrowth existed among rainfall, landslide and debris flow. In order to study the intergrowth and some key parameters, we carried out artificial rainfall landslide tests and model experiments to observe the phenomena such as collapse, surface slide and surface flow. By observing the experimental phenomena and monitoring water contents, the transformation process among landslide deposits and debris flow under the condition of rainfall had been analyzed. Research results revealed the relationship of this kind of intergrowth among rainfall, landslide and debris flow in Jiangjia Ravine. Meanwhile, it was found that this kind of intergrowth relationship existed only when the moisture content was in a certain range. That is, the critical state seemed to be existed in the transformation process. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
