Abstract: 

MASS MOVMENT OCCURRENCE IS ON OF THE NATURAL HAZARD WHICH WITH REGARD TO FREQUENCY AND ITS STRENGTH HAS ENVIRONMENTAL UNPLAESAN EFFECTS. ZONING MASS MOVEMENT OCCURANCE IS ONE OF THE WAYS THAT BY WHICH YOU CAN DISTANGUISH PREPARED AREAS AND THE CRITICAL ONE OF THEM IN ORDER TO PERMANENCE IT, AND USE THE AVAILABLE ZONING MAPS IN THE SUSTAINABLE DEVELOPMENT PLANNING. THE PRESENT STUDY, HAS DONE IN KALAN DAM OF MALAYER IN ORDER TO DISTINGUISH THE PREPARED AREAS OCCURRENCE OF MASS MOVEMENT AND RECOGNIZE ITS EFFECTIVE FACTORS. IN THIS STUDY, FACTOR SUCH AS, LITOLOGY, SPECT OF FAULT, SLOPE AND ACCUMULATION PLANT COVERING WERW SELECTED OF AMONG ALL EFFECTIVE FACTORS. BY USING THE AERIAL PHOTOGRAPHY, SQUARE OBSERVATION AND ARCGIS SAFTWARE THEY USED LNRF MODEL IN THE NECESSARY MAPS WERE PROVIDED IN THE NUMERICAL AND STRATUM FROM FOR ANALYZING THE OBTAINED DATA THOUGH STUDYING THE EFFECTIVE VARIANCES AS THE RESEARCH CONCEPTIVE TOOLS. BY WAIGHTING EVRY EFFECTIVE FACTORS IN MASS MOVEMENT OCCURRENCE, THE WEIGHTING MAP OF EVRY FACTOR PREPARED. FINALLY, BY PLUSING THE WEIGHTING MAPS, THE ZONING MASS MOVEMENTS HAZARD MAP PROVIDED. THE CASE STUDY WATERSHED DEVIDED INTO FIVE UNSTABLE CLASSES. THE OBTAINED RESULTS INDICATE LNRF MODEL HAS A RELETIVELY USAGE TO SEARCH AND ZONING HAZARD MASS MOVEMENTS. THE MORE STUDYING FOR FUTURE PLANS INCLUDING STOPPING OF RUINING AGRICULTURAL REGIONS, DECREASING THE SEDIMENTS OF BACJ KALAN DAM WATERSHED OF MALAYER AND ALSO, INCREASING THE USEFULNESS LONG-TERM LIFE OF IT IS NECESSARY.
