The Česma basin is fan-shaped and formed by a number of streams rising on the slopes of Bilogora and Moslavačka Gora hills.

Southern sides of Bilogora slightly goes downhill, rugged with numerous ravines and gullies, steeply and deeply cut in.

The area around the watercourse of Česma till a hundred years ago was subject of flooding, which is why it was swampy.

After that, Česma river and its tributaries was channelized, embankments were built for flood protection, and the soil is dried to obtain arable land as well as the fight against malaria.

At the site of former wetlands now are fish ponds that supply water from streams that flows into the Česma river.
