Human modifications of the landscape often cause changes in regional surface and subsurface water flow that in turn can result in alterations in the natural cycle of flooding and drawdown in wetland ecosystems.
Recurrent changes also occur when water (lake, reservoir, sea, and stream) and wetland levels fluctuate due to drawdown, agricultural practices, or natural variation in precipitation (24,650 ha), and as windthrow and dune movement overtakes vegetation (375 ha).
Lastly, the efficiency of various management schemes was evaluated by simulating the reaction of the spring, in terms of discharge, to a series of pumping scenarios, all guaranteeing a certain imposed withdrawal during summer, much larger than the natural spring discharge, given by spring discharge and well drawdown.
To help borrowers protect against catastrophes and other special risks, the bank offers a Catastrophe Deferred Drawdown Option to provide financing after a natural disaster or declared state of emergency.
The infield reinjection of the produced water is neither causing temperature decline nor pressure drawdown on the geothermal reservoir, which is following natural cycles.
Under these conditions, if recharge is not kept in balance with the rate of withdrawal, further drawdown of the water table will occur, and these valuable natural resources may be depleted.
This leads to a drawdown of carbon and less summertime outgassing (or more uptake) of natural CO2.
As the drawdown of carbon by primary production only occurs in summer and leads to less natural CO2 outgassing (or more uptake) in that season, the future seasonal trend of the SAM index and the interaction with a global warming signal will determine the future of the Southern Ocean CO2sink.
Bare soils can be the result of anthropogenic or natural events such as burial by wrack (Minchinton 2002 a ; Minchinton and Bertness 2003), a water level drawdown (Smith and Kadlec 1983; Galinato and Van der Valk 1986; Welling et al. 1988 a, b ; Tulbure et al. 2007; Whyte et al. 2008; Tulbure and Johnston 2010; Wilcox 2012), or removal of litter and vegetation by wave action (Baldwin et al. 2010).
This drawdown will continue.
