Damping and landfills

Description

Damping and soil pollution: In 1995, a Special Inventory Study on landfills and ditch damping was carried out for the entire rural area in South Holland, the Bio-s. It was an aerial interpretation, in which aerial photos from 1955 were compared with aerial photos from 1992. It was determined which watercourses and ponds that were still visible in 1955 had disappeared in 1992 and where there had to be a damping. In this way, approximately 40,000 damped locks were detected between 1955 and 1992. The fact that there is a ditch damping does not mean that there is also soil contamination. For example, it is known that locks in areas where a land consolidation was carried out are often filled with unsuspected land that was released elsewhere within the project. For individual parcels of arable land, the ditches are often ploughed densely and even in such cases the presence of soil contamination is not plausible in advance. Damping in the peat meadow area is different, because it often uses material that was supplied from elsewhere. These attenuations must be considered suspicious in advance. Furthermore, it can be said that attenuations are relatively less common in former polders. These have a subdivision with relatively wide plots and few, mostly also narrow ditches. Quality When using the data on ditch damping, a number of file limitations must be taken into account. The main limitations are: It is an interpretation of aerial photographs from the period 1955 - 1992. Damping outside this period is therefore not included. - The urban area and the urban extension areas from 1955 to 1992 were also excluded from the survey. - Interpreting aerial photographs in contiguous greenhouse areas has not been carried out, or has been carried out only to a limited extent, due to technical limitations relating to the tracing of damped locks. - Elevations, landfills and ditch dampings were recorded as a single layer of information during the aerial interpretation. - Due to misinterpretation of aerial photographs, a margin of error between 0 and 5 percent should be taken into account.These are errors due to overshadowed ditches, locks that have grown up due to natural landing, ditches that have been incorrectly interpreted as ditches and errors when digitising the photos. Data is mainly used by Ground Matters. Disclaimer: This map with ditch dampings is a snapshot and therefore not complete. It is likely that more locks are muted, which are not indicated on this map.
