(35 cards)
It refers to the soil’s ability to transfer gravity water downward, and that the soil is not conducive to prolonged periods of saturation
GOOD DRAINAGE
It is the rate at which water penetrates the soil surface (cm/hr or inches/hr)
INFILTRATION
It is the rate at which water within the soil moves through a given volume or material (cm/hr or inches/hr)
PERMEABILITY
It is the rate at which water is absorbed back by soil
PERCOLATION
It is the capacity of soil or rock to hold water; ratio of the volume of void spaces in a rock or sediment to the total volume of the rock or sediment
POROSITY
It is when the soil is frequently or permanently saturated and may have water standing on it. This may be caused by local accumulation of surface water or rise in the level of ground water within the soil because the soil particles are too small to transmit infiltration.
POOR DRAINAGE
It is the science that studies the waters of the earth, their occurrence, circulation, and distribution, their chemical and physical properties, and their reaction to the living environment.
HYDROLOGY
It promotes the highest rate of soil erosion
INTENSE RAINFALLS
It is a permeable geological stratum/formation that can both store and transmit ground water in significant quantities
AQUIFIER
It is a geographic area of land bounded by topographic features and height of land that captures precipitation, filters, and stores waters to a shared destination; this is important in water quality and stormwater management
WATERSHED
These are the four types of climate
COLD, TEMPERATE, HOT ARID, & HOT HUMID
These have a striking impact on the microclimate
TOPOGRAPHY
SURFACE MATERIALS
PLANT COVER
LOCATION OF STRUCTURES, PRESENCE/ABSENCE OF WATER
The factors to consider with regards to climate:
SOLAR ORIENTATION
BEST - FACING SLOPES
WIND FLOWS
It is the characteristic of a surface; fraction of total radiant energy of a given wavelength incident on a surface reflected back by that surface
ALBEDO
It is the technology of cooling spaces through proper siting of structure and use of energy-efficient materials with the overall objective of energy conservation
PASSIVE COOLING
It is a percentage which is calculated by rise divided by run (rise/run)
SLOPE
Slope that is considered: Relatively Flat/Level to Nearly Level
0-3%
A slope that is considered: Easy Grades
4-6%
A slope that is considered: Moderately Undulating to Steeply Sloping
7-14%
A slope that is considered:
Steep
14-18%
Slope that is considered:
Not alienable and disposable
> 18%
Slope that is considered: Rolling to Hilly
18-30%
Slope that is considered: Hilly to Mountainous
30-50%
Slope that is considered: Mountainous & Excessively Steep
50% & up
