More drainage ditches, before it rains: a countryside municipality's priority
Atri covers about 9,180 hectares, most of it countryside. When an autumn of heavy rain arrives in a territory like this, the first question is not "how do we protect ourselves from the water", it is "where does the water go". If we do not decide it, with a drainage ditch, a ditch, a clear culvert, the slope decides. That is why our proposal is a single one, and we repeat it: more drainage ditches, wherever there is a sloping field, and make them now, not in November.
Why this deadline
Three documented things, put in a row.
- The summer was dry. The Region lists Abruzzo among the Italian areas in extreme drought. The grape harvest began on 3 August, about ten days early.
- The Calanchi burned. On 30-31 August a fire affected the Reserve. Cause and extent do not appear in any official source we were able to consult, and we do not state them.
- Seasonal models lean towards a rainy autumn. ECMWF and Copernicus indicate, for October-December, a higher probability of above-average rain over the Mediterranean, with above-average temperatures. This is a probabilistic trend: it is not a forecast for Atri and it does not say how much rain will fall or where.
The link between these three things is our own hypothesis, not a study of Atri. But it is the hypothesis slope specialists commonly make after a fire: soil without vegetation, hardened by the dry spell and with ash on the surface, absorbs less, and if the rain is intense the water runs over it instead of entering, gains speed, carries soil and debris with it and dumps them into ditches, onto roads and into watercourses. The risk is decided in the first heavy rains, because that is when the soil is most exposed. Not knowing whether it will happen is no reason to wait and see.
Why Atri in particular
From our data, which are official maps and not field measurements:
- about 2,255 hectares out of 9,180 are mapped as landslide areas in regional inventories, and 690 hectares are badlands. Note: these are mapped areas, not necessarily active today;
- of about 400 km of roads and tracks in the municipality (from OpenStreetMap), 49 km cross areas mapped as landslide-prone. Of these, 26 km are tracks and dirt roads: the routes used to reach the fields;
- the olive groves and vineyards mapped by the regional land-use map are about 735 and 248 hectares;
- the Casoli landslide dates from 2017, the works were handed over on 30 May 2024 and in September 2026 are still under way (record 2026/0001506). The register also shows costs incurred "to deal with the flood emergency of November 2017" and, on 29 September, a commitment of 20,481.06 euros of housing aid for the bad weather of January 2017 (record 2026/0001575). The territory is not new to these events.
How it works, concretely
Water falling on a sloping field has three destinies: it soaks in, evaporates or runs off. If the soil is saturated, compacted or bare, the share that runs off grows. The longer it runs over an uninterrupted stretch, the faster it goes and the more it cuts: a small furrow becomes a rivulet, then an erosion gully.
A drainage ditch (or water furrow) breaks that length. It collects the water from one stretch of field and carries it sideways, towards a ditch, before it gains strength. Three things to know:
- its slope must be gentle: if it is too steep the water runs and cuts the ditch itself;
- it must end in a ditch, or a channel that can take it, not in the middle of a field nor on the edge of a scarp: a drainage ditch that ends nowhere concentrates the water at one point and makes it give way;
- it must be kept clear: a drainage ditch blocked by stubble, soil or leaves does not work, and sometimes makes things worse.
Above fields, where water arrives from a slope, a guard ditch is needed to intercept it. Along roads, drains, ditches and culverts must be clear: most damage from "water crossing the road" begins with a culvert blocked by reeds, soil and rubbish, not with an exceptional rain.
Other general measures for growers: on hills, grass between the rows or minimal tillage reduces erosion; in an olive grove, peacock-eye disease spreads with humidity and mild temperatures and copper, in organic farming, goes on before the expected rains; for the olive harvest, if the autumn is rainy it is better to stagger it and not wait for the last moment.
These are general indications, not agronomic advice: slope, soil and crop change the right work, and an agronomist or a neighbour who has known the land all their life is worth more than this page.
Whose job it is
It depends on who owns the work. Fields and the drainage ditches inside them belong to their owners. Roadside ditches may belong to the Municipality, the Province, ANAS or the adjoining owners; streams fall to other bodies. If it is unclear whose ditch it is, report it on the map: it is for this too, and if the competent body is missing the report remains as a record.
What we ask the Municipality
We ask in writing, as a request and not an accusation. We did not find in the register recent records on the cleaning of ditches and the minor drainage network: that does not mean it is not done, it means we do not see it. It would help to know:
1. who cleans the ditches and culverts that fall to the Municipality, when the last intervention was done and at what cost;
2. what was assessed for the areas downhill of the Calanchi after the fire, and whether there is a plan for the areas that water and debris could reach (the COC was closed on 21 September, record 2026/0001518);
3. where the Casoli works stand and when they are expected to end.
We will publish the replies in full.
Staying informed
Official hydrogeological alerts are on the Abruzzo Region's AllarMeteo site (allarmeteo.regione.abruzzo.it): green, yellow, orange and red codes, by alert zone. It should be checked which zone Atri falls in. With an orange or red alert: no roads near ditches and landslide slopes, underpasses, fords or cellars. For immediate danger: 112.
A drainage ditch costs little and takes an afternoon. A collapsed field, a blown culvert, a cut road do not. In a municipality made almost entirely of countryside, keeping these things in mind should be among the first.
- Record no. 2026/0001518: COC closed: the record refers to the August fire and says the emergency conditions are over
- Record no. 2026/0001506: Casoli landslide: works under way, funding of 5,334,281.52 euros
- Record no. 2026/0001575: Housing aid for the January 2017 bad weather: 20,481.06 euros committed in September 2026
Seasonal forecasts are probabilistic (Copernicus C3S). The link between drought, fire and erosion is the author's hypothesis, not a study of Atri. Landslide areas are mapped areas, not necessarily active. Road lengths come from OpenStreetMap. The advice on drainage ditches is general, not agronomic consultancy.
