The route crosses no major watercourses, although creeks adjacent to or spanned by the route drain into the Pazinčica and Boljunčica rivers, or directly into the Adriatic Sea in the case of watercourses flowing down Učka's eastern slopes.
However, while exclusion of buffer zones would result in some reduction of harvestable area, the majority of watercourses in these mainly dry sclerophyll forests are mapped as stream type of order 1 to 4, and have a buffer zone requirement of between 0 and 5 m stipulated by the Code of Practice (DNRM 2014).
A wall of sapele, a type of Nigerian mahogany, hangs above the watercourse.
In the EU, this type of monitoring activity already forms the central core of the Water Framework Directive (WFD), and requires that every watercourse within the EU27 has to be monitored periodically to determine its ecological status.

The great Maghribian wadis (French: oueds; channels of watercourses that are dry except during periods of rain) issue from the Atlas ranges.
Aerial and satellite photographs and maps can only begin to show the intricate tangle of watercourses and ancient irrigation channels present in the alluvial plain.
Catchment interventions such as fencing of watercourses, streamside buffer strips and constructed wetlands have the potential to reduce faecal pollution of watercourses.
Human interventions in the water cycle (drainage of landscape, amelioration of watercourses, pollution of water, etc).
Improvements are also documented regionally, such as successful support of farmland species, and improved condition of watercourses and landscapes.
The A5 motorway runs through plains crossed by a number of watercourses and railways running perpendicular to the motorway route, requiring a variety of bridges and viaducts.
