  • Modelling spatio-temporal heterogeneities in groundwater quality in Ghana: a multivariate chemometric approach

    Chemometric techniques were applied to evaluate the spatial and temporal heterogeneities in groundwater quality data for approximately 740 goldmining and agriculture-intensive locations in Ghana. The strongest linear and monotonic relationships occurred between Mn and Fe. Sixty-nine per cent of total variance in the dataset was explained by four variance factors: physicochemical properties, ...

  • Rock Island adult fishway extension - Case Study

    Rock Island Dam is located on the Columbia River, approximately 15 miles south of Wenatchee, WA. The development of a crack in a spillway of Wanapum Dam, downstream of Rock Island Dam necessitated a 25 foot drawdown of the tailrace. This created a significant obstacle for the fish migrating upstream; they would not have access to the original fish ladder. With the arrival of the ...
