Non-perennial rivers and streams make up over half the global river network and are becoming more widespread. Transitions from perennial to non-perennial flow are a threshold-type change that can lead to alternative stable states in aquatic …
Characterizing the drivers of flow in non-perennial streams is increasingly important for understanding the effects of variable flow regimes on local communities and ecosystems. Regime shift theory has been used to explain changes in other hydrologic …
Groundwater pumping can cause reductions in streamflow (“streamflow depletion”) that must be quantified for conjunctive management of groundwater and surface water resources. However, streamflow depletion cannot be measured directly and is …
Groundwater use can reduce streamflow by reducing groundwater flows into streams and/or increasing losses from the stream into the aquifer (‘streamflow depletion’). Streamflow depletion can impact aquatic ecosystems through changes in the …
Groundwater pumping can cause streamflow depletion by reducing groundwater discharge to streams and/or inducing surface water infiltration. Analytical and numerical models are two standard methods used to predict streamflow depletion. Numerical …
Non-perennial streams are widespread but understudied relative to their perennial counterparts. In this study, we investigated the flow and intermittency regimes for the Arkansas River near Larned using historical streamflow, groundwater level, and …
Estimating reductions in streamflow caused by groundwater pumping (‘streamflow depletion’) is critical for conjunctive groundwater-surface water management. Streamflow depletion can be quantified using analytical models, which have low data …
Water scarcity is a key challenge to global development. In Brazil, the Sao Francisco River Basin (SFB) has experienced water scarcity problems because of decreasing streamflow and increasing demands from multiple sectors. However, the drivers of …
Groundwater pumping can reduce streamflow by reducing groundwater discharge and/or inducing streamflow infiltration, which together are referred to as streamflow depletion. Recently, analytical depletion functions (ADFs) have been suggested as rapid …
Streamflow observations can be used to understand, predict, and contextualize hydrologic, ecological, and biogeochemical processes and conditions in streams. Stream gages are point measurements along rivers where streamflow is measured, and are often …
