development, the evaporative cooling and the solar energy on the development
surface. The last two can be used to derive a metric regarding the heat island
reduction bene
t that green areas offer to urban environment.
The MUS-Designer, via a user-friendly interface, simulates the urban water
cycle
fluxes related to both blue services (potable demand, run-off volume) and
green services (irrigation needs, run-off volume). Then, provides metrics related to
the performance of these two services and to the bene
ts derived from their inte-
grated operation (reduction of required raw water in
ow, run-off mitigation and
reduction of heat island effect).
Keywords and Definitions
ESS
Ecosystem Services
Green roof
Roof of a building that is entirely or to an extent covered
with vegetation planted over a waterproo
ng membrane
Green walls
Vertical plants either grown on freestanding structures or
attached to interior or exterior walls
In
ltration trench
Excavation
filled with permeable material, such as rock and
gravel, which is used to capture, treat, store and in

store and drain
MUS
Multiple use water services
MUSIC
Model for urban storm water improvement conceptualisation
Permeable
pavement
Method of paving that allows water to in
ltrate into the
ground as it falls rather than running off into piped storm
water drainage system
Rain gardens
Shallow planted depressions designed to receive rainwater
from hard surfaces such as roofs, paved areas or roads
Retention ponds
Provide both storm water attenuation and treatment, while
supporting emergent and submerged aquatic vegetation
along their shoreline
Swales
Shallow, broad and vegetated channels
filled with porous
filter media to provide on-site treatment of storm water run-
off

Storm water management model
Urban agriculture
Practice of cultivating crops for food in cities
Urban water
management
Emphasises decentralised storm water and rainwater man-
agement, such as Low Impact Development (LID) for USA,
Decentralized Urban Design (DUD) for Germany, Water
