Picture 1 Emerge area of island in rainy, midst and dry 
season 
The emerged area of island is 20327310 square meter in 
rainy season average water level (represented byl). 
The emerged area of island is 24089651 square meter in 
midst season average water level (represented by= 8). 
The emerged area of island is 26418678 square meter in 
Dry season average water level (represented by] ) 
The area of sand beach in dry season is 6091368 square 
meter. 
The area of sand beach in midst season is 3762341 square 
meter. 
4. CONCLUSION 
It is concluded that area of sand beach in different season can 
be measured by integrate hydrology data with remote sensing 
data from above experiment. In above experiment, water level 
of river represented by average water level of three seasons that 
can represent the change to a great extent, but it is still not 
enough because water level change at any moment. It is been 
thought that founding the mathematics relation of real time 
water level and area of sand beach would have better result on 
basis of continuously remote sensing monitor in longer period
