Area 2 i the soiltype and as is Lend Cover allowing consideration of lateral low and other losses, How to solve for different recharge volumes: By default the spreadshect assigns the values of tolal deficit recharge volume "VdeF and total proposed impervious area “Aimp” from the “Annual Recharge” sheet to "VdeF" and "Aimp" on this page. This allows solution for a single BMP to hanale the enlire recharge requirement assuming the runoff from entire impervious area is available to the BMP. To solve for a smaller BMP or a LID-IMP to recharge only part of the recharge requirement, set Vdef to your target value and Aimp to impervious area directly connected to your infiltration fi |ABMP
