A swell in geology is a domed area of considerable areal extent. [1] According to Leser, it is also called a sill (geology), and is a gently arched landform of various orders of size in topographic, sub-glacial or sub-hydric geology. It may be as small as a rock formation in a river or may assume continental scale. [2]
A constructed swale or bioswale built in a residential area to manage stormwater runoff. A swale is a shady spot, or a sunken or marshy place. [1] In US usage in particular, it is a shallow channel with gently sloping sides.
Properties that are influenced by soil texture include porosity, permeability, infiltration, shrink-swell rate, water-holding capacity, and susceptibility to erosion. In the illustrated USDA textural classification triangle, the only soil in which neither sand, silt nor clay predominates is called loam.
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or expansive soil . [ 1 ]
Soils with high shrink–swell capacity, such as vertisols, recover quickly from compaction where moisture conditions are variable (dry spells shrink the soil, causing it to crack). But clays such as kaolinite , which do not crack as they dry, cannot recover from compaction on their own unless they host ground-dwelling animals such as ...
Landscaping an elementary school courtyard in the city of Kuching. Landscaping refers to any activity that modifies the visible features of an area of land, including the following: Living elements, such as flora or fauna; or what is commonly called gardening, the art and craft of growing plants with a goal of creating a beauty within the ...
Depending on context, wave height may be defined in different ways: For a sine wave, the wave height H is twice the amplitude (i.e., the peak-to-peak amplitude): [1] =.; For a periodic wave, it is simply the difference between the maximum and minimum of the surface elevation z = η(x – c p t): [1] = {()} {()}, with c p the phase speed (or propagation speed) of the wave.
