Conceptual framework and planning guidelines for
integrated coastal area and river basin management.
Split: PAP/RAC, UNEP/MAP/PAP, Split, Priority

This document should be seen as a general tool while
d t il d d
detailed
descriptions
i ti
off natural
t l processes, h
human
activities and their interactions can be found in
specialised scientific literature. The document has two
parts. The first p
p
part p
presents a conceptual
p
framework
for Integrated Coastal Area and River Basin
Management, based on the hydrological, geochemical,
ecological and socio-economic linkages between the
river
i
b
basins
i and
d coastal
t l areas, while
hil th
the second
d partt
presents practical procedures for achieving the ICARM
goals. The Guidelines provide a conceptual framework
for initiating
gp
plans and can be used also on a selective
basis for specific aspects of integrated coastal area
and river basin management.

Basin discharge
Empirical model: balance between rainfall, evapotranspiration, and runoff
(Molisnai et al., 2006; Kjerfve et al., 1997; Molisani et al., 2007)
Q (m3/s) = ∫ ∫A r.(∆f/r).dA
where r is precipitation (mm/year,
(mm/year converted to m/s)
∆f/r is the runoff ratio
∆f/r = e-E0/r
where E0 is the potential evapotranspiration (mm/year)
(
y )
E0 = 1.109 e-4620/T
where T is the temperature in Kelvin degrees

Management Zones:
• a critical zone or a narrow band of land and sea a few hundred
metres wide, adjacent to the shoreline, usually of highest ecological
value and subject to intense pressures for development;
• a dynamic zone which may extend both inland and seaward, usually a
few kilometres wide, where there is strong dependence and/or
