Estimation of Baseflow Recession Constants
Hydrograph recession constants are required in rainfall-runoff models, base flow augmentation studies, geohydrologic investigations and in regional low-flow studies. The recession portion of a streamflow hydrograph is shown to be either an autoregressive process or an integrated moving average process, depending upon the structure of the assumed model errors. Six different estimators of the bas...
متن کاملEstimation of baseflow residence times in watersheds from the runoff hydrograph recession: method and application in the Neversink watershed, Catskill Mountains, New York
A method for estimation of mean baseflow residence time in watersheds from hydrograph runoff recession characteristics was developed. Runoff recession characteristics were computed for the period 1993–96 in the 2 km2 Winnisook watershed, Catskill Mountains, southeastern New York, and were used to derive mean values of subsurface hydraulic conductivity and the storage coefficient. These values w...
متن کاملA Review of Techniques for Analysing Baseflow from Stream Hydrographs
Understanding the groundwater contribution to streams is critical when dealing with a wide range of water management issues. Analysis of the streamflow hydrograph, specifically separating and interpreting baseflow (the longerterm delayed flow from storage) from quickflow (the short-term response to a rainfall event) is a well-established strategy in understanding the magnitude and dynamics of g...
متن کاملAssessing Degree of Karstification: a New Method of Classifying Karst Aquifers
Karst aquifers are often classified as highly heterogeneous systems. Such systems are very complex to assess and model due to the presence of discontinuous porosity, large spatial variability of hydraulic parameters and the difficulties encountered in establishing the fundamental spatial properties of the system. In fact, karst aquifers have been studied and classified into groups based on seve...
متن کاملUsing a fully coupled surface water - groundwater model to quantify streamflow components
Separation of streamflow components into quickflow and baseflow is usually carried out in two main ways: hydrograph recession analysis and tracer-based methods. In this paper, it is proposed to use a fully coupled surface and subsurface flow and transport model to gain a better understanding of the relationship between physical catchment characteristics (e.g. aquifer hydraulic conductivity) and...
