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.
Example 1 The linear-reservoir model (or Nash model) is widely used for rainfall-runoff analysis. The model uses a cascade of linear reservoirs along with a constant first-order storage coefficient, K , to predict the outflow from each reservoir (which is then used as the input to the next in the series).
Examples of the effects of climate change on agriculture: 2019 flooding of the Toki River caused by Typhoon Hagibis, which was exacerbated by climate change; [1] increase in global leaf area primarily caused by the CO2 fertilization effect; [2] 2020–present Horn of Africa drought, the worst drought on record and made worse due to the effects ...
Due to an increase in heavy rainfall events, floods are likely to become more severe when they do occur. [59]: 1155 The interactions between rainfall and flooding are complex. There are some regions in which flooding is expected to become rarer. This depends on several factors. These include changes in rain and snowmelt, but also soil moisture.
National Innovations in Climate Resilient Agriculture (NICRA) was launched during February 2011 [1] by the Indian Council of Agricultural Research (ICAR) with the funding from the Ministry of Agriculture, Government of India. The mega project has three major objectives of strategic research, technology demonstrations and capacity building.
The Los Angeles River is extensively channelized with concrete embankments.. River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit.
For example, agricultural flooding may occur in preparing paddy fields for the growing of semi-aquatic rice in many countries. Flooding may occur as an overflow of water from water bodies, such as a river, lake, sea or ocean. In these cases, the water overtops or breaks levees, resulting in some of that water escaping its usual boundaries. [6]
It is a method of controlled and intermittent irrigation. A periodic drying and re-flooding irrigation scheduling approach is followed in which the fields are allowed to dry for few days before re-irrigation, without stressing the plants. This method reduces water demand for irrigation and greenhouse gas emissions without reducing crop yields.
