Map 2 Digital elevation model of the study area
Relative humidity: The Relative humidity rates differ from month to another.
The values ranged from 19.08% in May to 49.23% in December. The annual mean
relative humidity was 30.8%.
Wind velocity: climate data shows that, the wind velocity ranges from 2.76 to
3.61 m/s in November and May, respectively.
3 Materials and Methods
The current study uses various kinds of multispectral satellite sensors for tracking
and mapping the land use land cover and its changes that occurred. These sensors
include Landsat TM (1988), Landsat TM (2003), and Sentinel 2 (2018) as shown in
Map 3. These used images were obtained from the USGS earth explorer site. Table 1
shows technical specification of these satellites sensors.
