The relief of Prut – Barlad Watershed Area belongs to Moldavian Plateau and to the North-Eastern part of the Romanian Plain. Landforms included in Prut – Barlad Watershed Area are the following: Moldavian Plain, fully located in Prut River Basin, with an average height of approx. 150 m. Sucevei Plateau, the Western boundary of Prut basin, where there is also the maximum altitude of 587 m (Dealul Mare – Tudora).

The Central Moldavian Plateau, made up of structural areas with an average height of approx. 400 m, fragmented by deep valleys (150 – 200 m). Pliocene hills (Tutovei Fells, Falciului Hills, Covurluiului Hills) with altitudes over 400 m to the North and of approx. 250 m to the South, separated by consequent valleys, 100 – 150 m deep, with slopes strongly affected by soil erosive phenomena. Tecuciului Plain and Covurluiului Plan are hilly plains, with widths of approx. 20 km to the South and heights ranging between 60 – 200 m.

By its position to the Eastern part of the country, the Moldavian Plateau has a temperate continental climate with certain particularities. In lowlands, a steppe climate is dominant, and in highlands, a climate characteristic to forested areas.
