Description
Infiltration from Stormwater Retention Ponds
MODRET is an easy-to-use interactive computer program that calculates unsaturated and saturated infiltration losses from stormwater retention/detention ponds in unconfined aquifers using a modified version of MODFLOW. Other uniquecapabilities include: Generation of single watershed stormwater runoff hydrographs using SCS Unit Hydrograph, Rational and Santa Barbara Urban Hydrograph methods with graphical display of the results. Routing of runoff hydrographs (MODRET-generated and/or others) through infiltration losses of ponds and generation of infiltration routed hydrographs. Specification of overflow devices (weirs, orifices and rating curves) for the stormwater retention/detention ponds and calculation of total volume and peak discharges. Generation of ground-water elevation cross-sectional graphics with ZOOM capabilities. Generation of XYZ data files which can be used by other programs (SURFER, AutoCAD, etc.) to generate ground-water contour maps and 3-D surfaces. Generation of report-quality tabular and graphical printouts of input and output data.
