Rain Water Harvesting
Flood control is usually limited to confining runoff within natural or man-made watercourses and standing bodies of water. Present flood problems are mainly due to the development of vacant lands, which are often subject to serious flooding without any commensurate, coordinated development of new drainage systems or expansion of the existing drainage systems. In many areas, the capabilities of existing drains, channels, and culverts have been exceeded during heavy rains. Additional problems occur when debris accumulates and clogs waterways. The absence of easements in drainage and flood courses also hinders maintenance The primary purpose of flood control sizing criteria is to reduce peak discharge from storm events to reduce the impact of local and “catastrophic” flood events. These events can have considerable impacts on property, structures and human live. This paper intends to provide general information to reduce the vulnerability of floods
