PROBLEM DESCRIPTION

• Temperate reservoirs annual cycle of
  stratification spring autumncirculation
• summer winter stagnation
• (epilimnion, metalimnion, hypolimnion)
• tropical reservoirs no knowledge
• Complete overturning may not occur
• QUESTIONS - Hydrodynamic processes?
• - Chemical processes?
• WHY useful for Water Supply Companies.

MODEL DESCRIPTION AND DATA SURVEY

• Focused on Hydrodynamic movements of water
• Water balance
• in rainfall, streams, wastewater, groundwater
• out intake, evaporation
• storage volume, retention time
• Forcing functions air temperature, sunlight
  penetration, wind forces, reaeration (air/water
  interface)
• Hydrodynamics depth distribution, water levels,
  thermocline, pycnocline, currents speeds
• RESULT Box Model for 3 layers

4
BASIC EQUATIONS

• Water balance

5
BASIC EQUATIONS

• Sunlight penetration, Beers Law
• Retention time

6
BASIC EQUATIONS

• Change in heat content

7
BASIC EQUATIONS

• 1-Dimension Transport Equation, Vertical
  dispersion

8
BASIC EQUATIONS

• Reaeration

Other equations to explore - heat emission
from evaporation/condensation - heat emission
from convection - solar radiation - oxygen
balance
