The floods inundated low-lying residential areas in Vijayawada and several villages downstream, causing significant damage to infrastructure, homes and agricultural land. [8] Historical data indicates that this flood event surpassed previous records, with only the 2009 and 1998 floods coming close in terms of discharge levels.
These techniques may be used in the identification of flood dynamics, [22] [23] storm characterization, [24] [25] and groundwater flow in karst systems. [26] Regression analysis is used in hydrology to determine whether a relationship may exist between independent and dependent variables.
Research into desertification is complex, and there is no single metric which can define all aspects. However, more intense climate change is still expected to increase the current extent of drylands on the Earth's continents: from 38% in late 20th century to 50% or 56% by the end of the century, under the "moderate" and high-warming ...
The agriculture sector is sensitive to climate variability, [200] especially the inter-annual variability of precipitation, temperature patterns, and extreme weather events (droughts and floods). These climatic events are predicted to increase in the future and are expected to have significant consequences to the agriculture sector. [ 201 ]
The most common types of surface water pollution are agriculture, sewage and waste water (including stormwater runoff), oil pollution and radioactive substances. [8] The agricultural sector consumes a lot of fresh water and is the leading source for water degradation. [8]
Research conducted at the Experimental Lakes Area indicates that creating reservoirs through the flooding of boreal wetlands, which are sinks for CO 2, converts the wetlands into sources of atmospheric carbon. [31] In these ecosystems, variation in organic carbon content has been found to have little effect on the rates of greenhouse gas emission.
Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Flood management methods can be either of the structural type (i.e. flood control) and of the non-structural type. Structural methods hold back floodwaters physically, while non-structural methods do not.
Recessional agriculture, also known as flood retreat agriculture, is a form of agricultural cultivation that takes place on a floodplain. Farmers practice recessional agriculture by successively planting in the flooded areas after the waters recede. [1] Seeds are scattered on the fertile silt deposited by the receding flood.
