different phases to distinguish

the position of the tempQsim project
water quality models(i) no consideration of
nutrient transformation in dry periods at
bottom (e.g. ATHYS-POL, RWQM1) (ii) limited
consideration of first flush evects
Supporting the EU Water Framework Directive in
Mediterranean catchments
tempQsim

synthesis of experience
hydrological modules for improved runoff
calculation, drying processes, GW-interaction
improved consideration of hyporehic habitat
dyna-mics and their interactions to aquatic
habitats
sediment modules for transformation, accumulation
and resuspension of organic matter /nutrients
during dry and wet periods
catchment models for semiarid regions special.
in runoff/ erosion no consideration of water
quality dynamics (e.g.Medrush, EUROSEM)
prognosis of riverine ecological functioning in
catchments
Improvement of availablewater quality models
gaps and state of the art
innovation of the project
future model evolution
