According to the equations, a basin with high drainage density, the contribution of surface runoff to stream discharge will be high, while that from baseflow will be low. Conversely, a stream in a low drainage density system will have a larger contribution from baseflow and a smaller contribution from overland flow. [8] [9]
The curve number can be adjusted by factors to , where factors are less than 1 (reduce and potential runoff), while factor are greater than 1 (increase and potential runoff). The AMC factors can be looked up in the reference table below.
Results showed that this approximation does not affect the calculated infiltration flux because the diffusive flux is small and that the finite water-content vadose zone flow method is a valid solution of the equation [13] is a set of three ordinary differential equations, is guaranteed to converge and to conserve mass. It requires the ...
A discordant system or pattern does not correlate to the topography and geology of the area. Discordant drainage patterns are classified into two main types: antecedent and superimposed, [2] while ante position drainage patterns combine the two. In antecedent drainage, a river's vertical incision ability matches that of land uplift due to ...
[2] [3] The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry human-made contaminants or natural forms of pollution (such as rotting leaves).
In science and engineering, hydraulic conductivity (K, in SI units of meters per second), is a property of porous materials, soils and rocks, that describes the ease with which a fluid (usually water) can move through the pore space, or fracture network. [1]
Amid the housing crisis in South Florida, Miami-Dade County has been floating two proposals that would increase housing density as a way to address the increasingly dire situation in our community.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
