Summary

The Biogeochemical lake model, BIOLA, was developed at SMHI for eutrophication studies in Sweden. The model is a one-dimensional (vertical) model that simulates temperature stratification and water quality influenced by weather, inflow and biogeochemical processes in the lake and in the sediments. The central variables simulated are inorganic nutrients and phytoplankton. It may simulate the biogeochemical effects in a lake from a changed enviroment. The changes may be eutrophication remedy actions, thus when considering different management actions BIOLA may contribute with valuable information. The Manual describes the BIOLA code. The BIOLA code consists of a couple of subroutines in four Fortran-files to be used together with the equation solver PROBE. The report describes how to use these subroutines to simulate the biogeochemistry in a lake, but only briefly how to use PROBE. The Manual describes data required, different ways to incorporate nutrient loads to the lake, how meteorological data is incorporated etc. It also describes how to change parameter values of the biogeochemical processes included in the model and calibrate the model to a specific lake.
