According to observations result 27 yearly in Ardesen region,
the coldest month is January that its temperature average is 6.7
°C, the hottest month is July that its temperature average is 22.2
°C . Rize is the rainiest city in Turkey, its total precipitation is
more than 2300 mm., and precipitation disperse every month
symmetrical. Heavy rainfall is the triggering variables which
shift the slope from a marginally stable to an unstable state and
thereby initiating failure in an area of given susceptibility. So,
landslides in the study area have been widely affected by heavy
rainfall. At the same time, heavy rainfall has been increased to
speed of weathering materials in the region. Thus, weathering
has been considerably reducing materials' resistance for
landslides susceptibility in the area. Observations result 27
yearly in Ardesen region has been evaluated and is shown the
results in Figure 2 and 3.
