Abstract
The development of lowlands has become a major issue for agricultural development in order to increase production yields. The characterization of these agroecosystems is necessary for the management of natural crises such as floods and droughts. This is the objective of this study at the Dokomey site in the municipality of Abomey-Calavi in Benin. Float gauging methods and infiltration methods using the Porchet method have made it possible to characterize the shallows. The latter is reinforced by field visits for direct observations and semi-structured interviews with the rice farmers who operate the site; The Strengths, Weaknesses, Opportunities and Threats (SWOT) matrix is the results analysis model used. The analysis of the results obtained shows that the site is crossed by a tributary of the Ouémé River named "Lokpa" with an average flow of 3.12 m3/s in the main canal. Runoff and rainfall are the secondary sources of supply at the site. Also, the soil of the study site is clayey-sandy with an average longitudinal slope of about 2.71% and its average transverse slope fluctuates around 3.99%. The permeability of the soil is 4.57.10-2m/s. Despite the potential, the operating groups encounter several difficulties. These are mainly related to water management but also to access to the site during flood periods. It would be wise to enhance the entire site with total control of water in all seasons by installing infrastructure that is more resilient to the current climate context.
