Base Flows

During dry periods, the flow of medium and small streams is significantly reduced and equal to groundwater flow. Since the base flows provide information about aquifer characteristics and retention characteristics of a basin, the possibilities of analysis and simulation of base flows gain importance under the conditions of intensive water use and the increasing demand for adequate water quality protection. In this paper, a model was established and used for the description of the principles governing the changes of base runoff on the basis of a streamflow hydrograph registered at the outlet of the basin on the example of the Kolubara basin up to the ?Valjevo? profile. Since the amount of base runoff from a basin cannot be measured, the results of base flows obtained using the local minimum method were adopted as the criterion for the comparison of the modelled values of base runoffs. The created model was applied for making simulations of the base runoff hydrograph during three characteristic years (rainy 1970, average 1985, and dry 1990). Deviations between the base flow values obtained using the established model and by applying the local minimum method are acceptable from the standpoint of general hydrological accuracy.

Abstract The metal mining Environmental Effects Monitoring (EEM) program will require mines to conduct effluent characterization and water quality monitoring on an ongoing basis. Samples will be collected four times a year, and will be analyzed for a range of parameters. This information will be used to aid in the design and interpretation of fish surveys and benthic invertebrate community surveys. There are also a number of water quality monitoring methods that may be used to help determine the cause of any effects identified by the EEM program. Mines will also be required to collect sediment samples for determination of particle size distribution and total organic carbon. This information will be used in the design and interpretation of benthic invertebrate community surveys. A range of sediment monitoring techniques are available to aid in the determination of the causes of effects on the benthic invertebrate community.
