Rising Tide and Soft Soil

Kevin and Jenny stand on the slope as the warm rain begins to thicken the mud. Jenny points to a cluster of Carex while Kevin monitors the barometer, noting the pressure rise.

Kevin and Jenny assessed the deepening slope fissure above the north ridge transect, finding groundwater seepage turning soil to slurry six inches down. They planned a stepped box drain using greenheart and canvas liner from the fissure to the spring culvert, pacing the twelve-meter run and noting the critical flattening of grade near the outlet. Kevin began a test auger hole upslope while Jenny sketched the cross-section and saturation line.

Look at the way the water is pooling under these roots—it's not just surface runoff anymore.

push a trowel into the fissure to check the soil depth and sketch the new pattern of the fracture.

💭 peek at the thought
The cracks are widening faster than the sketch showed; if I don't find the drainage point, the whole ridge will slide into the cove.

Fissure's deepened. How far down does it go?

Watch the barometer needle, then crouch beside her to see the trowel depth.

💭 peek at the thought
She's right — the water's finding new paths. That fissure wasn't this deep last week. If the north slope keeps shedding like this, the transect line's going to shift before the next survey.

At least six inches of depth, and the soil is turning to slurry.

pull the trowel out and examine the consistency of the earth, noting the breakdown of structure.

💭 peek at the thought
It's hitting the clay layer now; the water has own to go but out, saturating the whole slope.

Groundwater seepage. Not just surface water. We need to trench the upper slope before it takes the transect markers.

Pull the soil auger from the pack and start a test hole two meters upslope from the fissure.

💭 peek at the thought
Six inches of slurry means the root mat's failing. That's not just rain — the groundwater's pushing up from below. The whole slope's lubricating.

🌿 Jenny03:09

Right. If the water table is rising here, a simple trench won't cut it—we need a proper diversion.

open the notebook and sketch a cross-section of the slope, marking the soil layers and the saturation line.

💭 peek at the thought
If it's seepage, the whole math ridge is a ticking clock. I need to find where the pressure is building before the slope gives.

Box drain with greenheart. Canvas liner. Fall to the spring culvert. How much grade we got?

Pace the distance from the fissure to the spring outlet, counting steps.

💭 peek at the thought
She's thinking French drain with stone and geotextile, but we don't have geotextile. Could use the greenheart offcuts for a box drain, line it with the heavy canvas tarp strips. Need fall toward the spring outlet — that's the only gravity out.

🌿 Jenny03:11

It's about twelve meters to the spring, but the slope flattens out right where we need it.

use the level to check the drop between the fissure and the culvert opening.

💭 peek at the thought
If the grade isn't steep enough, the water will just sit in the liner and rot the whole thing out.

🔧 Kevin03:12

Step the grade. Steep upper, silt trap at the break, shallow run to culvert. Need stone for the trap — beach cobbles?

Walk the line to the spring, kicking aside turf to check the substrate at the flat section.

💭 peek at the thought
Twelve meters with a flat spot means we either dig deeper at the outlet or pump. No power for a pump worth a damn. Digging deeper means hitting clay — good for seal, bad for back. Could step the drain: steeper upper section, shallower lower, with a silt trap at the transition.
