%description
Empirical reservoir water quality modelling using Walker's 'BATHTUB' Model
1 (second-order available-phosphorus sedimentation) from Walker (1985)
<https://hdl.handle.net/11681/13884> and Walker (1996)
<https://hdl.handle.net/11681/4353> as the default retention model. The
Vollenweider (1976) hydraulic- residence form and the equivalent
formulation of Larsen and Mercier (1976) are available as alternatives.
Predicts in-lake total phosphorus, total nitrogen, chlorophyll-a, and
Secchi depth from tributary nutrient and hydraulic loading inputs, and
computes Carlson (1977) <doi:10.4319/lo.1977.22.2.0361> Trophic State
Indices. Optional Oklahoma-specific chlorophyll and Secchi regression
coefficients are provided, calibrated from publicly available state lake
monitoring data. Supports single-segment and multi-segment reservoir
configurations and load-reduction scenario analysis. Designed to
complement watershed loading models such as the Soil and Water Assessment
Tool ('SWAT'; <https://swat.tamu.edu>) and the U.S. EPA Hydrologic and
Water Quality System ('HAWQS'; <https://hawqs.tamu.edu>) in a two-model
nutrient management workflow.
