Cross Section Interpolation ganivi kveTis interpolacia

 Sometimes it is necessary to supplement surveyed cross section data by interpolating new sections between two surveyed sections  xandaxan saWiroa SevavsoT gamokvleuli ganivi kveTebis monacemebi, ori arsebuli ganivi kveTis interpolaciis saSualebiT.  Typically needed when the change in velocity head is large. HECRAS detects this by comparing conveyance values between two sections.  rogorc wesi am operaciis Catareba saWiroa maSin, rodesac gvaqvs mniSvnelovani cvlileba gadazidvis zewolaSi.
