Buffer strips were calculated for all water bodies subject to water protection zone requirements; however, where no agricultural land is present near the water body, a buffer strip may not be necessary.

Soovituslik kaldavööndite puhverribade laius Eesti looduslikele veekogudele ja maaparanduskraavidele, mis on arvutatud mullastiku ja reljeefiomadustest lähtuvalt kui lai võiks soovituslikult puhverriba olla juhul kui veekogu ääres on põllumaa (Uuemaa et al. 2026). Puhverribad on arvutatud kõikide veekaitsevööndi kohustusega veekogude äärde, aga kui seal põllumaad ei ole, siis ei pruugi puhverriba üldse vajalik olla.

Input data included a 5 m digital elevation model (Estonian Land and Development Board, 2025), EstSoil-EH soil dataset, natural water bodies, and drainage ditch datasets for Estonia. Slope, flow accumulation, flow length, and LS-factor were derived from the elevation model and combined into a composite specific slope length index. Soil texture classes were reclassified according to the nomograph requirements. Estonia was processed in 22 overlapping zones with 5 km buffers to preserve hydrological continuity and minimise edge effects. The resulting raster of recommended buffer widths was vectorised along water bodies into 5 m segments and then dissolved into one continuous buffer. Estonian Land and Spatial Development Board, 2025.

Uuemaa et al. (2026) välja töötatud soovituslike veekogude puhverribade soovituslike laiuste andmestik loodi üleriigilise ruumilise modelleerimise töövoo abil, mis rakendati Pythonis ja QGIS-is ning põhines Manderi ja Kuusemetsa (1998) empiirilisel nomogrammil. Sisendandmetena kasutati Eesti 5 m kõrgusmudelit (Eesti Maa-ja Ruumiamet, 2025), EstSoil-EH (Kmoch et al. 2021) mullastikuandmestikku, looduslike veekogude ning maaparandussüsteemide eesvoolude andmestikke. Kõrgusmudeli põhjal arvutati nõlvakalle, vooluakumulatsioon, voolutee pikkus ja LS-faktor, mis ühendati nõlva pikkuse koondindeksiks. Mullalõimise klassid klassifitseeriti ümber vastavalt nomogrammi nõuetele. Tulemuseks saadud soovituslike puhverribade laiuste raster teisendati vektoriks ja jagati veekogude ääres 5 m lõikudeks, kuhu loeti rastrist külge soovituslik laius ning seejärel ühendati üheks pidevaks puhveralaks.
