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,

5Cross Section Interpolationganivi kveTis
interpolacia
- Geometric interpolation is accomplished by
linearly interpolating between elevations and
stations along cords - geometriuli interpolacia xorcieldeba,
