At latitude ∼19°30′S, a threshold between exoreic and endoreic drainage regimes is clearly associated with the latitudinal gradient imposed by the modern monsoon (carrying humidity from the Atlantic) and disposed obliquely over catchments draining the Andes to the Pacific.
Many factors are thought to be responsible for the dramatic decline of this species in Australia, including habitat fragmentation, erosion and sedimentation of soil, insecticides and fertilisers contaminating water systems, the introduction of predatory fish, and alteration of drainage regimes.
The hydrology of the area is controlled by the drainage regime of the sluices in the Haringvliet barrier that was constructed as part of the "Delta Works" project to protect the southwest of the Netherlands against storm surges.
Our sigmoid-based model is able to reproduce: (i) oil remobilization induced by gas injection in water-wet media; (ii) a smooth transition towards the layer-drainage regime for low oil saturations; and (iii) the consequent reduction of residual oil saturation in a three-phase system.
This paper first describes a shallow water table model, based on deforming finite element (DFE) framework, to characterize the near-surface field-to-field hydrologic response to various irrigation and drainage management regimes along a gently sloping alluvial fan.
For example, the soil drainage and flooding regimes of inland valleys are influenced by the shape of the valley (Windmeijer and Andriesse 1993).
3. Building, mining, piling etc in prone areas can alter the loading, drainage and groundwater regime, thus increasing the likelihood of a sinkhole forming, or possibly speeding the process up.
It remains poorly understood whether the response of net aboveground biomass change and its components to climate change differ with local site conditions such as site drainage or moisture regime.
Dr Azzam Alwash, the president of NI, who was instrumental in the programme of re-flooding the Mesopotamian Marshes after years of drainage under the Saddam regime and has stayed in Cley village during visits to England, explains the reasoning behind the donation: "Nature Iraq has received great support from international organisations for the conservation of our famous Mesopotamian Marshes.
This study showed that the direction of transformation of native Chernozems in the Holocene period was strongly related to their position in the landscape, which affected the erosion/accumulation intensity and water drainage conditions (soil moisture regime).
But, it says, "intensive irrigation regimes and poor drainage practices have caused waterlogging and soil salinity throughout Pakistan's countryside.
