Benson, M.A. ‘Factors Influencing the Occurrence of Floods in a Humid Region of Diverse Terrain.’ U.S. Geological Survey Water- Supply Paper B, 62 : Wilbert O. Thomas. Medium type structures are mainly based on 50 years flood records e.g culverts, drainage structures and waterway structures. Large irrigation projects are based on years of flood record e.g Dams, reservoirs, headwork’s, barrages. Causes of floods: Intensive rainfall and high melting of snow are two main causes of flood. Factors affecting flood. Floods are also affected by the roughness of the terrain being passed over. Dense vegetation and artificial obstacles such as fences and houses will slow down water flow, often leading to lower flood levels downstream. Swamps and natural ponds or lakes have .

There are several other factors which make Bangladesh prone to flooding: very low floodplain gradients, the reduction of stream channel capacities due to the building of infrastructures such as. The influence of rainfall on rice flood substantially depends on rainfall intensity. Rice floods in Southwest China are typically triggered by short, intense by: 6. Many of these floods were catastrophic, reaching unprecedented flood levels (Figure 1), and affecting hundreds of thousands of people. Such flood‐related disasters are of global concern with the increasing concentration of population in urban settlements [ Jha et al., ] and the heightened exposure of assets to flood by: The Devastating Effect of Flooding in Nigeria Angela Kesiena ETUONOVBE, Nigeria Key Words: Floods, Devastating, occurrence. Whereas flooding itself is a situation that results when land that is usually dry is covered artificial factors. Flooding has been experienced in File Size: KB.

Water may seem benign, but in huge quantities it can be an enormously destructive force. When floods occur they bring with them numerous problems, ranging from the physical impact of water damage to the problems of disease and famine that can follow such disasters.

Factors that affect hydrological relationships between small and large catchments are reviewed, including the various processes and mechanisms by which runoff occurs, catchment characteristics such as land use, soils and geology, the variation of geomorphological characteristics with catchment size, small-scale nonhomogeneity of hydrological characteristics, and data by: Factors affecting the occurrence and structure of fish assemblages in isolated wetlands of the Upper Coastal Plain, U.S.A Factors affecting the occurrence and structure.
