CAMEL (Chemicals, Agricultural Management and Erosion Losses) is a physically-based, fully-distributed watershed model developed to provide detailed simulations of non-point source pollution runoff processes in small-scale catchments. The model has undergone continuous advancement to incorporate the unique environmental and hydrological characteristics of Korea.

• Inflow Tributaries of Daecheong Reservoir / Geum River Environment Research Center (2017)

• Rural Watersheds (Pangyo-ri, Dun-ri, Soyang-ri) / National Institute of Environmental Research (2014–2017)

• Daegwallyeong Hanwoo Experiment Station / Rural Development Administration (2014–2016)

• Yeoju-gun Watersheds, Gyeonggi-do / Rural Development Administration (2007–2011)

• Sihwa Lake Watershed / Ministry of Oceans and Fisheries (2007–2010)

• Usancheon Watershed, Masan / National Institute of Fisheries Science (2010)

• Tarland Burn Catchment, UK / The Scottish Government (2002–2005)

The CAMEL model provides a high-fidelity modeling framework through:

• Fully Distributed Modeling Approach: Explicitly represents spatial heterogeneity by discretizing the watershed into fine-scale grids or units.

• Physics-based Process Representation: Simulates individual hydrological and water quality cycles based on fundamental physical governing equations.

• Integrated Hydrological Simulation: Facilitates the coupled modeling of surface water and groundwater interactions.

• Small-Scale Precision: Optimized for high-resolution assessment and evaluation of hydrology and water quality in sub-catchments.
