Optimization of the methodology for valorization of mud retained by dams: Morocco case study

Dams are mainly built to store water, but they also accumulate a lot of sediment that consolidates over time. This mud harms the functioning and safety of dams and neighboring communities.

In addition to preventive measures to mitigate siltation, dam managers often resort to de-siltation as a corrective approach. However, this method generates significant volumes of mud, causing environmental damage and significant land losses.

Faced with the scarcity and increasing costs of raw materials, the use of the mud retained by dams as a resource in various fields is becoming essential. By exploiting the potential of sludge, we can alleviate the pressure on traditional raw materials and promote sustainable practices in all industries.

This article proposes a new optimal methodology for the use of mud retained by dams, based on global research. It specifies the laboratory tests to be carried out, the limit values to be respected, and a systematic process to improve the efficiency of the use of mud while respecting standards and best practices.

In addition to the presentation of the optimal methodology developed, the article includes a case study to illustrate its practical application. Focusing on the Moroccan context, we show how our approach can be adapted in real situations, providing a useful resource for professionals involved in the extraction of mud from dam reservoirs.
