“…The main methods of reservoir leakage detection include abnormal flow field analysis, borehole geophysical exploration, the seismic surface wave method, GIS, hydrochemical analysis, the tracer test, and other geophysical methods [5][6][7][8][9][10][11]. Among these, the groundwater tracer test represents a crucial methodology for elucidating flow systems, and is extensively applied in hydrogeological surveys and the identification of leakage within the hydraulic structures [12].…”

In areas with complex hydrogeological conditions, the tracer test method is often used as an effective means in hydrogeological surveys. According to the results of tracer tests, hydrogeological parameters, including hydraulic gradient and permeability coefficient, fracture network leakage passages and their scale, and groundwater flow rate and direction can be quantitatively determined. This paper takes the upper reservoir of Yongxin Pumped Storage Power Station in Jiangxi Province as the research object, and focuses on the complex hydrogeological conditions of the upper reservoir. Three sets of tracer tests and multiple sets of single-hole flow rate and direction tests were conducted on the left and right banks of the reservoir and near surface gullies. The results showed that ZKS18 received tracers in all three tests, which indicates a close hydraulic connection between ZKS18 and the left bank, right bank, and surface gullies within the reservoir. Based on the single or multiple peak values of the tracer, it was determined that there are 1–6 leakage passages in the fractured rocks, with leakage passage sizes of 0.1–0.4 mm. According to the single-hole flow rate and flow direction tests, a self-developed instrument was used to determine the groundwater flow rate and flow direction at different depths in the test holes, which yielded results that were basically consistent with the results of the three-hole method. These results provide a basis for the use of tracer tests in hydrogeological surveys for water conservancy and hydropower engineering, and anti-seepage design of upper reservoirs.

“…This upheaval is reflected today in an amplification of climatic dynamics and an acceleration of climatic events such as cyclones and heat waves [5,6]. In addition, trends towards global warming are already causing disruptions in the precipitation cycle which result in extreme phenomena such as floods or droughts which affect food production [7][8][9][10][11].…”

Cameroon aspires to emergence by 2035. Since 2009, it has drawn up reference documents such as the “Vision 2035” and the “Strategy Document for Growth and Employment”, which include growth goals such as poverty reduction, economic development, industrialization, democracy and unity. In addition, in the document of the Intended Determined Contribution to the National Plan submitted to the United Nations, the country undertakes to reduce its greenhouse gas emissions up to 32% by 2035, with particular emphasis on renewable energy which will contribute 25% of total electricity production. The Sudano-Sahelian region of Cameroon is the region most threatened by climate change. For more than a decade, actions have been carried out both under government leadership and private initiatives to reduce the effects of global warming on the socio-economic development of the region. In our work, we will present some of the local action plans experienced both in the laboratory and in the field based on energy, agriculture, environmental techniques, and hydraulics and water control.
