Description of the study area - Lake Kerkini
Description of the study area - Lake Kerkini
100.000 ha arable land84.000 ha are irrigated54.400 are irrigated from Lake Kerkini & Strymonas River
The concept
Simulation of the lake’s water balance
Estimation of the lake’sWater volume
hypsographic curves
Lake’s Surface - Water Level
Historical climatic data
Future climatic data
Past & Present Future
Methods and Tools
Si+1 = Si + Qin + P – E – I – Qus - Qout
S : volume of water stored in the lake in time step i and i+1Qin : catchment runoff into the lake at time step i
P : precipitation on the lake’s surface in time step i
E : evaporation from the lake’s surface in time step i
Qus : water outflow from the lake to the users in time step i
Qout : water outflows downstream the lake in time step i
- Time step : monthly- The terms are expressed in m3
I : Infiltration from the lake’s bottom in time step i

Methods and Tools
For the simulation of rainfall – runoff in thelakes’ catchments
MIKE BASIN isa GIS tool suitable for water resources management and planning
MIKE BASIN (NAM)was applied in bothcatchments
NAM a module of MIKE BASIN isa deterministic, lumped hydrological model which represents variouscomponents of rainfall-runoff process
NAM hydrological models of the lakes’ catchments were calibrated on observed time series of the lakes’ water level
