Nonetheless, in many other locations, water availability is critical for advancement beyond the current inadequate levels of development, as well as for the survival of existing populations or the continually increasing demand caused by fast population increase. Dam and reservoir development is critical in these locations for harnessing water resources. Seasonal changes and inconsistencies in river flow impede the proper use of water runoff, resulting in catastrophic situations such as flooding and drought. Dam steel gates have been used for quite a long time now to provide a sufficient water supply by holding water during times of excess and releasing it during periods of scarcity, therefore avoiding or moderating floods.
