Constraining the intermittency of flow and sediment transport in the geological past

Sinead Lyster - The Pennsylvania State University

Quantitative reconstructions of ancient river dynamics usually provide insights into either instantaneous flow conditions or mean flow conditions. There is a critical gap between these timescales of investigation, which reflects the intermittency of flow and sediment transport. At present, this gap is difficult to reconcile. If we can constrain intermittency, we can begin to narrow down hydrograph shapes and, therefore, hydroclimate in the geological past.
