Abstract
Our understanding of hydrologic and sediment transport processes in low order, high slope, gravel bedded mountain streams is quite limited. Remoteness of sites, the infrequent nature of events and related logistical difficulties have left us with little integrated, quantitative data on the basic hydraulic, hydrologic and sediment transport processes in such environments. A research facility has been established within the Ouachita National Forest of Arkansas at which an artificial stormflow generating system has been put into operation. The system consisting of a combined pump and reservoir system provided a controlled release of water in a manner which enabled replication of stormflow conditions in an adjacent test study reach. The results of initial runs are presented. A series of five releases were undertaken to evaluate questions of sediment supply depletion and basic transport dynamics. Instrumentation employed involved integrated arrays of electromagnetic flow meters, suspended and bedload samplers, tagged rocks, and pre- and post-event channel and bank surveys at selected cross sections in the test reach.
