Abstract

Long-term data for understanding and simulating processes at the watershed scale CW Slaughter Eco-Hydraulics Research Group, University of Idaho, USA Abstract Ecohydraulic modeling to support management of landscapes and stream systems presupposes availability of data with which to develop and exercise numerical simulations. Otherwise "comprehensive" data sets may be inadequate for eco- hydraulic modeling. Examples include: long-term streamflow and climate records for a specific catchment without water quality or suspended sediment data or with inadequate characterization of essential landscape characteristics; and, stream channel characterization at the river basin level which is inadequate to support model application at the headwaters spatial and temporal scale. Hydrologic data from long-term research watersheds in northeastern Russia and central Alaska illustrate the former condition, in which data acquired at great effort and expense may be inadequate for specific eco-hydraul
