# Intertidal survey of Kellow Sands and Thrimby Point Report BEP/SR/2026/11 · Survey of 19 to 23 January 2026 · Issued February 2026 # Summary The four fixed transects at Kellow Sands and Thrimby Point were resurveyed in January, in the third winter since sediment recharge began. This report sets out the method, the profiles measured, and the change on each transect since the surveys began. Levels were taken at five-metre intervals along each transect with a total station from the survey marks on the training wall and at the lifeboat house. Sediment samples were taken at the mid-shore station on each transect for particle size, and are reported by the laboratory separately. Conditions during the survey were settled, with no swell and a spring range near the mean. Nothing about the week's weather is likely to have affected the levels measured. **Background** The Partnership has surveyed the intertidal at Kellow Sands since 2019, when the four transects were established to provide a baseline for the sediment recharge then being planned. The first two winters were surveyed before any material was placed. Placement began in the winter of 2023/24 and has been carried out in each winter since, most recently between November 2025 and January 2026. The purpose of the survey is a narrow one. It is meant to answer whether the intertidal profile at Kellow Sands is gaining or losing sediment, and at what rate, on lines whose position is fixed. It is not a study of where the placed material goes, which would need tracer work the Partnership has not commissioned, and it cannot by itself attribute a change to the recharge rather than to the weather. **Method** Levels were taken with a total station from the two survey marks used since 2019, at five-metre intervals along each transect and at every break of slope between them. Each line was run twice, out and back, and the two sets agreed everywhere within the tolerance the method allows. Where they did not, which happened once on transect three, the point was re-observed. The horizontal position of each line is fixed by a mark set in concrete at the landward end and by a pin in the training wall or the marsh edge at the seaward end. All eight marks were found and checked against the 2019 coordinates before work began. The pin at the seaward end of transect two has moved and was re-established from the landward mark; the correction is recorded in the level book and is smaller than the interval between observations. Sediment samples were taken at the mid-shore station on each line, in the order in which the lines were surveyed, and delivered to the laboratory the same afternoon. Particle size is reported separately and is not discussed here. <!-- PAGE BREAK --> **The transects** Transect one runs from the seawall opposite the boatyard to the low water mark, crossing the widest part of the sand. It is the longest of the four lines and the only one on which the whole intertidal profile can be surveyed within a single tide. Transects two and three are the pair the recharge was expected to affect. Both cross the placement footprint at its northern end, transect two some sixty metres from the discharge point and transect three about a hundred and forty. Neither has been moved since it was established, and the marks at both ends of both lines were found in good order. The plan below shows the four lines as they were surveyed in January, together with the saltmarsh edge as it stood at the 1998 survey. The 1998 edge is drawn because it is the last edge surveyed on the ground rather than taken from photography, and because it is the line against which the advisers have asked that marsh extent be reported. <figure type="DIAGRAM">Figure 1. Survey transects at Kellow Sands and Thrimby Point. Sampling stations are shown as filled circles and the 1998 saltmarsh edge as a broken line. <description>The diagram depicts a survey site map divided into two main areas: 'Kellow Sands' on the left and 'Thrimby Point' on the right, oriented with a North arrow pointing up. Four vertical survey transects (T1, T2, T3, T4) are drawn spanning the area. Each transect features three filled black circles representing sampling stations distributed along its length. A dashed line running horizontally across the transects represents the '1998 saltmarsh edge'. The lower boundary of the diagram is marked by a solid blue line above a light blue shaded region, while the upper boundary is defined by a light beige region containing the location labels.</description></figure> Transect four crosses the toe of the training wall and has always behaved differently from the other three. It is retained because the wall itself is the reason for the difference, and because the Partnership was asked in 2019 to keep a line there. The stations shown on the plan are those at which sediment samples are taken, and not the points at which levels were observed: the level observations are too close together to plot at this scale. A full set of profiles is bound into the copy of this report held by the secretariat. <!-- PAGE BREAK --> # Change since the first survey Change is reported as a mean annual rate over each winter, taken across the whole intertidal part of the line. Accretion varied markedly between transects, and the pattern is the same in each of the three winters measured. <figure type="CHART">Mean sediment accretion by transect, winters 2023/24 to 2025/26 <description>A grouped bar chart displaying mean sediment accretion in mm/yr across four transects over three winter periods: 2023/24 (dark grey), 2024/25 (medium grey), and 2025/26 (light grey).

A mean of that kind conceals a good deal. On transect two most of the gain is in the upper third of the profile, and on transect four the loss is almost all at the toe of the wall; the profiles show this plainly and a mean does not. The advisers' view, which the secretariat shares, is that three winters is too short a run to separate the effect of placement from the variation the estuary shows anyway. The transects should be resurveyed next January on the same lines and by the same method before anything is concluded from them. <!-- PAGE BREAK --> **The next survey** The profiles themselves, the level books and the mark check sheets are held by the secretariat and are available to Partnership members on request. The next survey is due in January 2027. The secretariat proposes to keep the January window, and to ask the laboratory for particle size on the same four stations so that the series stays comparable. <!-- doc_id=parse-01m22n4vxge28dz3xhhps3absp -->

Expected vs. Found
| ✗ | Expected: The chart preserved as an image in position with its title; added textual data is optional.Found: The title remained in place, followed by a description and table, but the chart image was not returned. |
Supporting proof
Proof 1Screenshot
Proof 2Screenshot
Why this result
The chart needed to remain an image with its title. The complete PDF was converted successfully, but the image was absent, so this is a fail rather than a missing result. The endpoint has no supported option for returning the chart image.
Also observed in this test case
Approximate chart values. The sediment accretion chart’s table contains twelve values corresponding to the plotted bars, each marked as approximate.

How this scenario is graded
How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.
How results are decided
Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.
The rules
- Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
- Fail: at least one expected behaviour clearly didn't happen; the test case's result says which one and quotes the tool.
- Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the test case's result says what's missing.

Act on this result
Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.
This matches what I see
You run the same kind of test against your own setup and get the same behaviour.
Agree →This does not match
Yours behaves differently. Tell us what you got, with a screenshot if you have one.
Disagree →Point out an issue
Something here is wrong — a reference value, a transcription, a grade.
Report an issue →We have fixed this
Tell us what changed and we schedule a rerun of the failing test case. The old result stays as history.
