Thiruvananthapuram: The Kerala State Land Use Board said that drought post-floods may not be the reason for the sudden wilting of water in waterbodies in the state.
The floods washed away the sand in the most of the waterbodies which have increased their depth. This could be the possible reason for it and as the water table in the rivers lowered it also affected the water level in the wells.
The KSLUB evaluated that not even 10 per cent of the water received through the flood was collected as groundwater. The phenomenon of wilting in the rivers and wells after floods is not drought. The water level was decreased by the heavy flow of flood waters into the waterbodies ruining their natural characteristics.
Since the sand in the rivers and other water resources have been washed away, the water level came down resulting in the decrease in water level in wells.
The KSLUB also added that all these aftereffects are common when floods hit suddenly.
