Abstract

Knowing the number, AREA, and VOLUME of LANDSLIDEs is important in order to determine LANDSLIDE susceptibility and hazard to evaluate the long term evolution of landscapes dominated by mass wasting processes. Determining the VOLUME of a LANDSLIDE is a more difficult task that requires information on the surface and sub-surface geometry of the slope failure that, at present, can be achieved only by adopting EMPIRICAL RELATIONSHIPs to link the VOLUME of individual LANDSLIDEs to geometrical measurements of the failures, chiefly LANDSLIDE AREA. In this research, at first, the data of 442 LANDSLIDEs in MAZANDARAN PROVINCE including AREA, VOLUME and depth was provided. Then a new EMPIRICAL RELATIONSHIP was calculated for prediction of LANDSLIDE VOLUME and this relationship was evaluated. Subsequently similar relationships in literature review were applied for the LANDSLIDE observation data of MAZANDARAN PROVINCE and were compared together. Results show that calculated VOLUME values by new EMPIRICAL RELATIONSHIP is in agreement with observed data (R2=0.823, Pvalue= 0.000) and some relationships which revealed applicability of presented relationship. Also for Mazandaran LANDSLIDEs, the relationships which were presented for large LANDSLIDEs in their study AREAs were more applicable than those presented for small LANDSLIDEs in their study AREAs. Regarding new relationship, the mean of LANDSLIDE depth was determined 7.81 m that was close to mean of observed depth (7.38 m).
