Floods on the pool Slutty
What are the causes?
The primary cause of these flows was of course the intensity storms that hit in Hainaut. However, these problems were compounded for various reasons: row crops and in the direction of the upstream slope of the villages, the loss of wooded landscape (hurdles), land consolidation, soil sealing by increased urbanization and / or the creation of roads, the disappearance and / or lack of ditch maintenance, lack of maintenance of drainage system ...
These incidents can they be limited or eradicated?
Thanks to scientific advances in this area, public authorities apprehend better and better interactions causing flooding and damaging runoff.
Plan "RAIN" (Plan for Prevention and Fight against Floods and their effects on losses) from 2002 includes 30 measures aimed at achieving five objectives: improving knowledge of flood risk, reduce and slow runoff throughout a watershed, increasing the flow capacity of rivers and water storage in floodplains, reducing flood vulnerability and improve crisis management.
In terms of agriculture, some actions have already been implemented but could be widened. These include good agricultural practices, agro-environmental measures (AEM) or the replanting of hedgerows. For example, reducing lengths of slopes contributes to the fight against runoff. FAD as the establishment of grass strips, or winter soil cover installed on a voluntary basis by farmers, create a barrier to creating more runoff and keep the land arable fields. The planting of hedges (which is also a subsidy) to create a barrier to flow.
Increased impervious surfaces reduce the infiltration of stormwater overloads the drainage system and increases the speed of runoff. To overcome these negative effects, conservation of natural ditches for draining water is essential, as is proper maintenance of the roads bordering collectors.
But actions can also be performed at home: harvesting rainwater (tank), the implementation of green roofs or the use of filtering materials (gravel, porous concrete, open, bark, etc..) Allows reduce stormwater runoff.
The item shown on the next page can also serve as a tool for the problem of runoff.
RAIN PLAN: A new order to aid the fight against floods and mudflows caused by runoff
The Walloon Government of 18 January 2007 (MB 12.02. 07), on the granting of subsidies to government subordinate to the establishment of devices for protection against erosion of farmland and the fight against floods and mudflows due to runoff, sets terms of access to ERC grants, as well as the designation of beneficiaries and their obligations to allow access.
devices to control erosion, retain runoff, maintaining the value agricultural land and limit damage to property downstream can be:
- of rural engineering,
- the work of planting and planting
- tests required for the execution of works
- acquiring undeveloped property necessary to complete the above work or payment of a compensation for the creation of an easement for temporary immersion.
Such aid applications must include the opinion of the manager of the watercourse in question, along with official documents including agricultural and hydrological study, the special specifications of the work complies with the specification standard 99 of the Region Walloon ...
A complete dossier must be forwarded to the Minister, via Escort service in order that the Minister can decide on the acceptance or otherwise of that file. In the positive case, the Minister shall arrange for the commitment of budgetary spending and takes a ministerial granting subsidies.

Muskrats, you know?
Information VC Senne
native of America, * muskrat (Ondatra zibethicus) was introduced in Europe in 1905, mainly for its fur.
how to identify it?
Muskrats exclusively associated with stream is large (30 to 36 cm for a weight of 1 to 1.2 kg), has a vertically flattened tail and lives in the banks of streams, in which he set up a network of galleries. This feature is causing damage to many banks inducing dyke failures, destabilization of riverbanks and requiring to be cleaned more frequently rivers (muskrat can move 1 m3 soil / year).
In addition, the muskrat has a vegetarian diet and therefore addresses all cultures riparian and aquatic plants and accentuating the decline of biodiversity in wetlands. It can also be a vector for diseases transmissible to humans, such as leptospirosis or alveolar echinococcosis.
This species is considered harmful and is the subject of a rodent control program implemented by the cell trapping muskrats in the Ministry of the Walloon Region, under the Royal Decree of 19 / 11 / 1987 concerning the fight against organisms harmful to plants and plant products.
How to act?
First by circulating information on problems that may cause the muskrat and the need to fight against.
To eradicate the muskrat, Service Trapping muskrats in the Walloon region uses different methods: mechanical traps, chemical means (the only product approved: chlorophacinone), hunting ...
If you see this rodent or possible damage linked to it along the river, contact the Contract Slutty River at the bottom of the page. It will transmit information directly to the Department of trapping muskrats in the Walloon Region.
* Not to be confused with the Norway rat (20 to 25 inches long without the tail, weight: 250 to 300 g, rounded and sharp-tailed), the most common in homes, connected to the network sewage, garbage, streams and places of food storage (farm, silo, shed). In his home and his property, the owner (or tenant) is obliged to destroy the sewer rats. However, private firms, joint task of planned interventions (usually in autumn and spring) or on appeal. Some communal services sell (or distribute for free) bait poisoned.
