WebSep 16, 2024 · Slope the trench to ensure proper drainage. Measure the depth of your trench using a line level. Pound a stake in near the house to use as a reference point. Tie the string exactly level to each stake and measure the depth. You’ll need to increase the depth as you get farther from the well. Adjust the gravel at the base of the trench as … A triple junction is the point where the boundaries of three tectonic plates meet. At the triple junction each of the three boundaries will be one of three types – a ridge (R), trench (T) or transform fault (F) – and triple junctions can be described according to the types of plate margin that meet at them (e.g. Fault-Fault-Trench, Ridge-Ridge-Ridge, or abbreviated F-F-T, R-R-R). Of the ten possibl…
