The activities that humans do that contribute to flooding are: deforestation - this removes the tree roots that holds soil in place to hold some of the water. Humans also build on land, removing green areas to make roads, drives, and there is not enough drainage on these surfaces for water to be absorbed into the soil.

Human activities such as land degradation, deforestation of catchment areas, increased population density along the riverbanks inadequate land use planning, zoning, and control of flood plain development; and inadequate drainage, and management of discharges are examined when determining the factors that have contributed to the increased incidence of flooding of the past 100 years until 2004.
