Road salt model

A storage pool for road salt that emits salt to the surrounding areas can be explicitly described (see switch SaltRoadStorage). The input rate to this pool is given in a PG-file. Salts leave the pool through emissions, q_ClRoadEm, calculated as a fraction e_coef of the amount of salt in the road salt storage pool, C_ClRoad:

                                                 (2.60)

Only a fraction of the emitted salts infiltrate in the surrounding land, as determined by the coefficient r_coef:

                                                (2.61)

where q_ClRoadInf is the infiltration rate of salts originating from the road storage pool.
