Abstract
New microscale techniques have become
available to assist urban designers in better water
management. Urban water management has focused
on two different areas: stormwater, and water supply.
The focus of stormwater management is shifting
towards Low-Impact Development, which emphasizes
better management of urban stormwater through
reductions in postdevelopment runoff by increasing
onsite infiltration. Water supply planning has been
enhanced by the emergence of the field of end-use
demand management; the focus of much of which has
been on outdoor irrigation. Implementation of these
two objectives requires evaluation of processes at
smaller scales in order to focus on changes being
contemplated at a parcel level. A modeling approach
is presented which incorporates decentralized options
for management of both stormwater and urban water
supply. Management options that can be evaluated
with this approach include restrictive irrigation
policies and rainwater harvesting. A simpler model
based upon SCS (Soil Conservation Service)
hydrology is then calibrated to the more complex
model using a commercially available nonlinear
solver. A method for calculation of costs to the
consumer and evaluation of total system cost is
presented.
