The erosional debris flow processes on the right side of the riverbed of Mletis-Khevi, a tributary of the Tetri Aragvi, are assessed on the basis of field and laboratory studies. The values of the mountain slope erosion in the Mletis-Khevi catchment area have been determined on the basis of...

The knowledge of past events is important for the assessment of debris-flow hazard. Amongst the sources of information, documents from historical archives are particularly important in sites where the debris flows cause damage to urban areas and transportation routes. The paper analyses the...

In this paper, a methodology is proposedfor the delineation of debris-flow deposition areas.First, based on the theory of reliability,the delineated hazardous area is defined. Then,uncertainty analyses of all the uncertainparameters affecting the probable maximum length,width and thickness are...

The Jerte Valley is anortheast-southwest tending graben located in the mountainous region of west central Spain (Spanish Central System). Mass movements have been a predominant shaping process on the Valley slopes during the Quaternary. Present day activity is characterized as either `first-time...

In this paper, based on the concepts of uncertainty and reliability analyses, a method used for assessment of risk due to debris flow events is proposed. First, procedures for obtaining the configuration of debris-flow fans are presented. Then, the parameters affecting the configuration of...

The assessment of the debris flow hazard potential has to rely on semi-quantitative methods. Due to the complexity of the debris-flow process, numerical simulation models of debris flows are still limited with regard to practical applications. Thus, an overview is given of empirical...

The erosional debris flow processes on the right side of the riverbed of Mletis-Khevi, a tributary of the Tetri Aragvi, are assessed on the basis of field and laboratory studies. The values of the mountain slope erosion in the Mletis-Khevi catchment area have been determined on the basis of...

Debris flows constitute a major threat forseveral urban settlements located on the fans ofmountain catchments and for other infrastructures thatinteract with these fans, particularly highways andmotorways. Often structural measures such as theconstruction and maintenance of deposition...

Two sets of empirical models for debris flow hazard assessment on gully-specific scale are presented herein, which may be the first step toward developing a formalized procedure for debris flow hazard assessment. Emphasis is put on comparison of the two models between Multiple Factor Composite...

Landslides, debris flows and stream floods are common natural processes inNorthern Italy. Their occurrence can be correctly assessed in space and timeonly through a sound basis of knowledge acquired by the scientific use of alarge number of historical documents. Over the last 30 years, the CNR...
