Data on soil characteristics (permeability, depth, drainage, pH, nitrogen, phosphorus, bulk density, and composition), with a 1 km resolution, were obtained from the Commonwealth Scientific and Industrial Research Organisation CSIRO Australian Soil Resource Information Systemem [ 14].
For model initialization, soil thickness, organic carbon storage, texture (fractions of sand, silt, and clay), bulk density, and drainage were initialized from the soil database.
The three basic ingredients are: garden soil for fertility and bulk, mineral aggregate for drainage and organic matter for water retention.
Extensive green roofs substrates should meet a list of physicochemical and biochemical requirements to be used as a basis for plant growth: high water holding capacity, good aeration, low bulk density, and proper drainage are some of them.
After initiation, lahars move downslope, typically along river drainages, and bulk up by eroding and incorporating surrounding material (Rodolfo 2000; Vallance 2000).
Taken together, this suggests a significant contribution of tracer drainage by ISF bulk flow from the striatum into the ventricular system.
When the dorsal and ventral pancreatic duct systems fail to join during embryogenesis, the condition is called "pancreas divisum," and it results in inadequate pancreatic drainage because the bulk of the pancreatic gland drains through Santorini's duct via the minor duodenal papilla [ 11].
The federal government is pushing the provinces to agree to a national ban on the bulk removal of water from all drainage basins.
As commented by others [ 45, 94], our current understanding includes bulk flow mechanisms for the movement and drainage of ISF along white matter tracts and the perivascular spaces.
Aß is cleared from the brain by proteolytic degradation [ 41], bulk flow along the perivascular interstitial fluid drainage pathway [ 42], or by receptor-mediated clearance across the BBB [ 43].
