Chii chinonzi geomorphometry?
Geomorphometry, kana geomorphometrics, ndiyo sayenzi uye tsika yekuyera hunhu hwenzvimbo, chimiro chepasi repasi, uye mhedzisiro yechimiro chepasi ichi pahunhu hwevanhu uye zvakasikwa. Inobatanidza nzira dzakasiyana-siyana dzemasvomhu, dzokuverenga uye dzokushandisa mifananidzo dzinogona kushandiswa kuenzanisa morphological, hydrological, ecological uye zvimwe zvinhu zvepasi renyika. Mashoko anowanzoshandiswa achireva geomorphometry ndeaya anoti geomorphological analysis (shure kwe geomorphology), terrain morphometry, terrain analysis, uye land surface analysis. Geomorphometrics inyanzvi inodzidza nezvezvinhu zvakadai sezviyero zvekuenzanisa zvemaumbirwo, nzvimbo uye chimiro chemazamu epasi, uye kuchinja kwazvinoita munguva. Ichi chinhu chikuru chinobatanidzwa muzvirongwa zvemashoko ezvenzvimbo (GIS) uye zvimwe zvishandiso zvepurogiramu yokuongorora nzvimbo.  Zvichitaurwa zviri nyore, geomorphometry inovavarira kubvisa (nyika) pamusoro parameter (morphometric, hydrological, mamiriro okunze nezvimwewo) uye zvinhu (watersheds, rukova network, landforms nezvimwewo) vachishandisa chiyamuro digitaalinen nyika pamusoro womuenzaniso (aizivikanwawo digitaalinen kukwirira womuenzaniso, DEM) uye parameterization Software. [Extracted pamusoro parameters uye zvinhu zvinogona kushandiswa, somuenzaniso, kuvandudza mapping uye modelling ivhu, zvinomera, kushandiswa kwenyika, geomorphological uye geological zvinhu uye zvakafanana.  Nekuwedzera nekukurumidza kwenzvimbo dzeDEMs nhasi (uye kunyanya nekuda kweShuttle Radar Topography Mission uye LIDAR-based mapurojekiti), kucherwa kwepasi pevhu parameter kuri kuramba kuchikwezva kuminda yakawanda kubva pakurima chaiko, kugadzira ivhu-nzvimbo modelling, mamiriro ekunze uye hydrological kunyorera kuronga kwemaguta, dzidzo uye kutsvagisa nzvimbo. Nzvimbo yenyika inenge yose yave ichienzaniswa nhasi kana kuongororwa, kuitira kuti DEMs iwanikwe pane zvisarudzo zve 100 m kana zviri nani pamwero wepasi rose. Nhamba dzomusoro wenyika nhasi dzinoshandiswa zvinobudirira zvose zviri zviviri kuenzanisa uye kuenzanisa-kwakavakirwa, nyaya bedzi yakasara iri mwero wezvinyorwa uye kururama kweDEM.
