|
Focal point spring "the eye" |
waterflow in soils become saturated and come to surface creating a gravity spring |
|
|
|
dispersed spring |
when waterflow is diffused •boxless "burrito style" successful •french drain / subsurface drain successful |
|
|
|
seep development |
seeps go subsurface during the summer months y joints used to collect water within seep drain area and converge it into a spring box with anti seepage walls |
|
|
|
raincatchment system |
•roof •gutters •debris guard •downspouts •first flush diverter •water storage |
|
|
|
gutters |
continuous slope, avoiding pools |
|
|
|
downspouts |
chains to aluminim downspouts |
|
|
|
rainwater catchment equation |
water (gal)= area (ft2)×precip (in)×roof effic (.XX)×.623 |
|
|
|
keyline |
catching water at highest point, using slightly off contour terracing to spread water out evenly across slope |
|
|
|
swale plume |
constructed on contour excavated material used to create a berm downhill •stones or gravel before berm •downhill from berm vegetated |
|
|
|
watering system |
•animal water requirements X head × X gal/day •flow rate °gallons per minute = (60sec/min×volume of container)÷ filling time °gpm×60 min×24 hr = water /day °10% of head × 1/2 gpm/head= minimum flowrate •distance •piping •verticle distance |
