the entire study area, the estimated average erosion rate is 
approximately 0.485 m?/n?, and the average rate of deposition 
is 0.005 m?/m?. 
Volumetric change for the year of 1996-1997 showed that 
entire study area experienced more deposition than erosion. For 
example, Section 3 had the largest amount of deposition 
(10,929.1 m?) while Section 6 had the largest amount of erosion 
(5,446.6 m? and exhibited the greatest net loss of 1,117.1 m". 
In contrast, volumetric changes for the year of 1997-1998 
showed that entire study area experienced more erosion than 
deposition. For example, Section | had the largest amount of

of deposition (16,846.3 m?). Section 2 exhibited the largest net 
loss of 9,169.1 m?, and Section 4 demonstrated the largest 
amount of sand exchange (between deposition and . erosion) 
with a loss of 6,073.9 m? and deposition of 4,498.5 m?. For the 
period of 1998-2000, volumetric analysis showed that entire 
study area experienced more erosion than deposition. For 
example, Section 1 had the largest amount of erosion (16,274.6 
m^) and at the same time had largest amount of deposition 
(10,729.3 m?). The erosion and deposition in Section | are 
almost twice that of other Sections, and Section 2 exhibited the 
largest amount of net loss (3,962.2 m?).
