    Notes: A method is presented for selecting ground-water flow paths by comparing modeled and measured hydraulic conductivity distributions. A flow chart is included which shows the steps followed in selecting the concept of groundwater flow which best fits measured hydrogeologic conditions.Both noneffluent and effluent stream conditions are evaluated using the method. Residual maps of hydraulic conductivity are used to show how modeled hydraulic conductivity may be as much as 300 times that expected when the wrong concept is used. Flow nets of modeled and measured data downstream from a flood-water-retarding structure are developed using the selected hydrogeologic conditions.Fitting hydraulic conductivity data results in a distribution of ground-water flow paths which better represent actual flow conditions. The method provides a unique means of calibrating a model in a pilot test area and applying it to geologically similar nearby watersheds. It is also useful for checking paths of subsurface flow where flow distribution is important as it is in the movement of chemical pollutants or nutrients from a source of recharge, such as a watershed impoundment, to downstream waters.

    ELECTRONIC DATA PROCESSING SYSTEM FOR STREAMFLOW (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 4 (1968), S. 0 
    Details
    ISSN: 1752-1688
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying , Geography
    Notes: Daily, monthly, and yearly summaries of streamflow and sediment transport are computed from continuous gage height records and discrete measurements of sediment concentration and discharge rate. The system includes computer computation of discharge measurement notes and an accuracy check of gage height and time input data. Maximum volumes of runoff for selected time intervals up to eight days and flow duration data can also be compiled. Electronic data processing equipment including a chart reader, card punch, computers, and card sorter are used. The system software includes 12 Fortran programs.

    HYDROLOGIC IMPACT OF WEATHER MODIFICATION (1975)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 11 (1975), S. 0

    Notes: : Weather modification is being proposed as a routine method of augmenting agricultural water supplies in the Southern Great Plains. This paper discusses some of the potential hydrologic impacts of weather modification. Previous work in assessing hydrologic impact is covered; the conclusion is drawn that the work is insufficient. An approach based on hydrologic models is suggested that can consider uncertainties about the effect of weather modification on rainfall and some uncertainties about the effect of model error on impact conclusions.
