Current climate and practicing a modern and sustainable agriculture imply the need to rehabilitate the entire network of irrigation systems found in Băilești Plain. There are 9 irrigation systems with 1.015 km of canals, spread over an area of 194.648 ha. These large constructions, which cross the Danube meadow and terraces, induced morphological c...

... Map of Romania was consulted, scale 1:200.000, 1968 edition, I.G.R.; Map of land use: European Environment Agency, CLC 2012 version 18.5.1; Topographic Map, scale 1:25 000, DTM (Military Topographic Direction), 1982;Google Earth 2012, 2016 Starting from the typology of the existing canals in the irrigation arrangements and their characteristics (Fig. 3 a, b, c, d), from July to Octomber 2019, field investigations were carried out in the Nedeia-Măceșu Irrigation System. The approximation of the volume of material deployed for the construction of irrigation canals was made based on their measured morphometric characteristics and the use of the following ...

Waterways are usually contaminated with wastes from industrial, domestic or irrigation sectors. Organizations in charge have adopted solutions to eliminate this problem; however, the adopted solutions contribute indirectly to modifying canal morphology during maintenance. These are examples of anthropogenic activity, as well as randomly implemented dredging, which expand the canal cross-sections. Egypt is a country which depends on surface irrigation through a huge network of canals. The majority of canals in Egypt are subject to anthropogenic activity which affects their efficiency. This study aims to assess the impact of conjugated instances of anthropogenic activity and dredging on canal morphology and capacity. Five canals were selected in the current study in the Nile Delta, Egypt. These canals are highly affected by two associated factors: anthropogenic activity by users and dredging by the government. The study also aims to determine the effects of a newly adopted policy for saving surface water through restoration of the canals’ originally designed cross-sections. The results showed a clear change in canal morphology, which has increased the volume of water in the affected canals. In some cases, the volume of water has increased by 59%, which could have negative consequences for Egypt’s water resources. Sustainable management of water resources in Egypt requires saving each water droplet, and canal rehabilitation is expected to save about 6.56 million m3/year by the year 2022.
