  • 18. Hydrological drought <ul><li>Hydrological Drought is associated with the affect of low rainfalls on water level in reservoirs, rivers &amp; lakes .This type of drought are noticed sometimes after a meteorology drought. </li></ul><ul><li>A hydrological drought change in water level affects eco-system </li></ul>
