Pesisir Selatan District is located on the coast, with a coastline of 218 kilometers. The topography consists of plains, mountains and hills. The expansion of agricultural areas in Pesisir Selatan District has an important meaning given the limited land for agricultural cultivation in the area. The water level will fluctuate due to the influence of the season and rainfall, where during the rainy season the soil is flooded and during the dry season it will recede, so that plant commodities to be developed must pay attention to their adaptability to groundwater depth. This research aims to support government programs in reclamation of agricultural land in an effort to maximize the function of lebak swamplands. Primary data includes groundwater and water in canals, temperature, soil physical properties, and rainfall. The analysis used is an analysis of the relationship between rainfall, temperature, soil physical properties, and the water level in the canal to fluctuations in the groundwater level. The results of the analysis show that temperature, rainfall, soil conductivity, and the rise and fall of the water level in the canal have an effect on the rise and fall of the groundwater level. Dynamic model in water management can be used as a guideline for the use of lebak swamp land during the Covid-19 pandemic. The potential for utilizing lebak swamp land as an alternative for future land through the concept of optimizing land resources is carried out with an integrated farming system that is environmentally friendly.
