Surface transient storage (STS) and hyporheic transient storage (HTS) have
functional significance in stream ecology and hydrology. Both provide refugia for aquatic
communities and their longer mean residence times (compared to the main flow) increase
the potential for biogeochemical reactions that can improve water quality. As STS and
HTS have...
