Q

Surface water - Dams & Impoundments

A

EFFECTS OF IMPOUNDMENTS INCLUDE A SERIES OF CHANGES IN THE PHYSICAL CONDITIONS DOWNSTREAM OF THE DAM, ESPECIALLY MODIFICATION OF FLOW AND TEMPERATURE REGIMES AND USUALLY GREATER WATER CLARITY

WATER QUALITY CHANGES MAY BE SLIGHT OR CONSIDERABLE, DEPENDING ON WATER RESIDENCE TIME IN THE RESERVOIR AND WHETHER SURFACE OR DEEP WATER IS RELEASED.

MODIFICATION OF PHYSICAL AND CHEMICAL CONDITIONS RESULT IN CHANGES IN THE PLANT AND ANIMAL LIFE OF THE RIVER

31
Pumping groundwater causes sea water to migrate into freshwater aquifers: Issues: less freshwater, once intrusion occurs it cannot be reversed

Common contaminants in groundwater
HYDROCARBONS METALS ELECTROPLATING OPERATIONS CHLORINATED SOLVENTS CHLOROPHENOLS
33
Hydrocarbons
SERVICE STATIONS BULK STATIONS FUEL HEATING OIL

SAWMILLS AND WOOD PRESERVATIVE PLANTS OIL FILL/REFUSE LANDFILLS

36
Chlorophenols
SAWMILLS WOOD PRESERVATIVE PLANTS
37
Contaminants move through the unsaturated zone to the water table, at the water table the contaminants will either continue moving downward through the groundwater or stop. Once at the water table contaminants can dissolve into the groundwater. Migration depends on the chemical and physical characteristics of the contaminants
GROUNDWATER CONTAMINANT MIGRATION
38
Occurs when large amounts of groundwater are withdrawn from certain types of soils (typically fine-grained)
LAND SUBSIDENCE
39
Main cause of Jakarta sinking up to 10cm per year.
EXTENSIVE LAND EXTRACTION DUE TO GROUNDWATER PUMPING PRESSURE FROM HIGH-RISE BUILDINGS, WHICH IS PUSHING PARTS OF THE CITY DOWN
40
Common where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater. As the rock dissolves, spaces and caverns develop.
SINKHOLES
41
Human induced sinkholes
GROUNDWATER PUMPING CONSTRUCTION/DEVELOPMENT CHANGING WATER - DRAINAGE PATTERNS CREATING RUN-OFF STORAGE PONDS WEIGHT OF NEW MATERIAL/BUILDINGS
42
The term first introduced by the Brundtland Commission (1987) in their report "Our Common Future" and is defined as : " the development which meets the needs of the present without compromising the ability of future generations to meet their own needs"
SUSTAINABLE DEVELOPMENT
43
Sustainability - Three E's Balance Rule
ENVIRONMENT EQUITY (SOCIETY) ECONOMY
44
Sustainable development basis as to political and ethical principle.
THAT THE SOCIAL AND ECONOMICAL DYNAMICS OF MODERN ECONOMIES ARE COMPATIBLE BOTH WITH THE IMPROVEMENT OF LIFE CONDITIONS AND THE ABILITY OF NATURAL RESOURCES TO REPRODUCE (REGENERATE) IN AN INDEFINITE MANNER
