Low Impact Development (LID)


Home

Low Impact

Development features

are small and part of

the subcatchment

runoff flow. They are

best simulated as part

of the subcatchment

and to be successfully

modeled they need to

be varied and

unlimited in number.

1. Evaporation and infiltration losses from

Storage nodes under Kinematic Wave and

Steady Flow.

2. Unlimited Low Impact Development/BMP

controls per Subcatchment connected to

infiltration and aquifers.

3. Pollutant buildup over a given landuse can

now be specified by a time series instead

of just a buildup function.

4. Improved linkages between lakes, flow

routing, evaporation and infiltration.

New Feature: You can now have an

external time series loading of

subcatchment buildup as well as no buildup

or the various functional buildup.
