“…The farmers were provided with the possible mitigation measures of managing their land resources scientifically, as evolved from available knowhow/technologies, soil investigation report and interactive discussion/brainstorming among farmers, field staff and experts. However, water losses from irrigation canals are directly influenced by soil permeability, which is affected by several factors, including mineral composition, granulometric composition, porosity, stratification, temperature, and hydrostatic pressure [9][10][11][12][13].…”

The Sardar Sarovar project, featuring a gravity dam on the Narmada River in Gujarat, stands as one of the largest in terms of concrete volume globally. This study investigates the project's extensive canal network and its impact on agricultural productivity in the command area. Covering a vast expanse across multiple states, the project's irrigation allocation and water management strategies are examined. Special attention is given to addressing soil degradation issues, particularly salinity, and implementing farmer-centered interventions to enhance water use efficiency. Methodologies include land rejuvenation efforts, reclamation of salt-affected land, participatory irrigation management, and promoting improved agricultural practices. Results indicate successful mitigation of soil degradation and increased crop yields through strategic interventions like cotton-castor relay cropping which has demonstrated a 1.5-fold increase in income compared to sole cropping. Intercropping with isabgul/ajwain, and implementing deficit irrigation have resulted in a substantial 43% increase in overall yield, particularly in cumin cultivation. Farmers have also embraced innovative water-saving techniques, such as alternative furrow irrigation and strategic timing of irrigation during critical growth stages, resulting in water savings of 30-35%. However, challenges remain in achieving widespread adoption of participatory irrigation management practices. The study concludes with insights into the necessity of sustained social engineering efforts and community engagement for long-term water resource management and agricultural sustainability in the project area.

“…Seepage loss, not only affects the delivered amount of water, but also causes different problems, such as waterlogging, which has negative effects on the soil-air-water balance in plants' root zone, consequently decreasing crop yields. As well conveying contaminants to the ground water [10], it causes grass and weed growth in adjacent land [11]. However, the seepage of water from irrigation systems is a major source of groundwater recharging, which is considered one of the main sources of fresh water in Egypt [10].…”

“…Seepage losses from irrigation networks depend on various factors, such as the underlying soil permeability, canal water depth, wetted perimeter length, groundwater level, and velocity of the flowing water [10,11]. Seepage losses can be measured in situ using inflow-outflow, ponding, and double ring infiltration methods [1,4,12,13], in addition to the electrical resistivity method [14].…”

“…Besides with the lining of earthen canals, seepage losses can be also reduced through other techniques, such as decreasing the wetted perimeter and increasing the flow velocity [1,10,17]. Despite the lower cost of these techniques, the maintenance of canals is regularly required and its efficiency is lower than lining techniques.…”

Owing to the potential negative impacts of climatic changes and the grand Ethiopian renaissance dam, water scarcity has become an urgent issue. Therefore, the Egyptian Ministry of Water Resources and Irrigation has started a national project of the lining and rehabilitation of canals, to reduce seepage losses and for efficient water resource management. This study presents a new approach for assessing three different lining and crack techniques for the Ismailia canal, the largest end of the river Nile, Egypt. A 2-D steady state seep/w numerical model was developed for the Ismailia canal section, in the stretch at 28.00–49.00 km. The amount of seepage was significantly dependent on the hydraulic characteristics of the liner material. The extraction from aquifers via wells also had a considerable impact on the seepage rate from the unlined canals; however, a lesser effect was present in the case of lined canals. The concrete liner revealed the highest efficiency, followed by the geomembrane liner, and then the bentonite liner; with almost 99%, 96%, and 54%, respectively, without extraction, and decreasing by 4% for bentonite and geomembrane liners during extraction; however, the concrete lining efficiency did not change considerably. Nevertheless, the efficiency dramatically decreased to 25%, regardless of the lining technique, in the case of deterioration of the liner material. The double effect of both deterioration of the liner material and extraction from the aquifer showed a 16% efficiency, irrespective of the utilized lining technique.
