# Seepage

The volume of water lost by seepage through the bottom of the reservoir on a given day is calculated:

&#x20;        $$V_{seep}=240*K_{sat}*SA$$                                                          8:1.1.7

&#x20;where $$V_{seep}$$ is the volume of water lost from the water body by seepage (m$$^3$$ H$$_2$$O), $$K_{sat}$$ is the effective saturated hydraulic conductivity of the reservoir bottom (mm/hr), and $$SA$$ is the surface area of the water body (ha).
