Experimental Studies on Water and Solute Transport Processes in a Hydraulic Model of the Severn Estuary, UK

Osei-Twumasi, A.; Falconer, R.; Bockelmann-Evans, B. - In: Water Resources Management 29 (2015) 6, pp. 1731-1748

<Para ID="Par1">A physical model that consisted of a glass reinforced plastic model, constructed to a 1:25,000 horizontal scale and with a 1:125 vertical scale of the Severn estuary was designed and fitted into a tidal basin at Cardiff University. The model, which was first of its kind, was used to conduct...</para>

Examining Point-Nonpoint Trading Ratios for Acid Mine Drainage Remediation with a Spatial-Temporal Optimization Model

Zhao, Xiaobing; Fletcher, Jerald J. - 2005

A trading ratio is required for water quality trading that involves nonpoint sources to compensate for the difficulty of determining nonpoint loadings, the stochastic characteristics of nonpoint loadings, and the uncertainty inherent in nonpoint source pollution control strategies. Compensating...

Tinto Versus Odiel: Two A.M.D. Polluted Rivers and an Unresolved Issue. An Artificial Intelligence Approach

Grande, J.; Aroba, J.; Andújar, J.; Gómez, T.; Torre, M. - In: Water Resources Management 25 (2011) 14, pp. 3575-3594

. Although the Tinto and Odiel Rivers, which cross the Iberian Pyrite Belt, have been widely studied by various authors, an issue … Fuzzy Logic. This showed that the order of abundance for the parameters analyzed for the Odiel River is SO<Subscript>4 … presents mean values of 361.1 mg/L, whereas in the Odiel River iron mean concentration is 5.34 mg/L. This difference is due to …

Time Evolution of an AMD-Affected River Chemical Makeup

Torre, M.; Grande, J.; Jiménez, A.; Borrego, J.; … - In: Water Resources Management 23 (2009) 7, pp. 1275-1289

Acid mine drainage is the main problem encountered by sulphide mining operations, not only because of its ecological aspects, but also because, once it appears, it is very difficult to remediate both technologically and economically. This paper characterises the response of an acid mine...

Nitrate, Total Ammonia, and Total Suspended Sediments Modeling for the Mobile River Watershed

Alarcon, Vladimir J.; Sassenrath, Gretchen F. - In: International Journal of Agricultural and Environmental … 8 (2017) 2, pp. 20-31

This paper presents details of a water quality model of the Mobile River watershed that estimates total suspended sediments at the outlet of the watershed. The model is capable of simulating Nitrate (NO3), Total Ammonia (TAM), and Total Suspended Sediments (TSS) for extended periods of time at a...
