  4. Cross Section Interpolationganivi 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.

  5. Cross Section Interpolationganivi kveTis interpolacia Geometric interpolation is accomplished by linearly interpolating between elevations and stations along “cords” geometriuli interpolacia xorcieldeba, horizontebis gaswvriv mdebare sadgurebsa da simaRleebs Soris xazovani interpolaciis saSualebiT. • 2 Options – 2 parametri • Interpolate a reach (more than 2 cross-sections) • gawvdomisinterpolacia (2 zemetiganivikveTi) • Between 2 cross-sections • 2 ganivkveTsSoris
