The flood pulse concept explains how the periodic inundation and drought (flood pulse) control the lateral exchange of water, nutrients and organisms between the main river channel (or lake) and the connected floodplain. [1] The annual flood pulse is the most important aspect and the most biologically productive feature of a river's ecosystem.
Wetter winters mean longer flooding time and potentially deeper flood pools. [1] As flood levels begin to rise, plant species that are not used to flooding will be affected. This will also change dynamics between flora and fauna by limiting food and habitat space. Also, increased agriculture and development are future threats.
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.
Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. 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 ...
The country is considered highly vulnerable and is expected to experience worsening cyclones, flooding, heatwaves, and drought. As a large percentage of the population is dependent on local agriculture, these changes are expected to impact industry in the country as well. [42] September 2019 climate strikes in Dili, East Timor.
This can encourage farming; [4] some important agricultural regions, such as the Nile and Mississippi river basins, heavily exploit floodplains. Agricultural and urban regions have developed near or on floodplains to take advantage of the rich soil and freshwater. However, the risk of inundation has led to increasing efforts to control flooding.
Flood forecasting is a multifaceted discipline that aims to predict various aspects of flood events, including their occurrence, magnitude, timing, duration, and spatial extent. However, the scope and definition of flood forecasting can differ across scientific publications and methodologies.
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.
