Increasing water scarcity in many countries provides a strong impetus for investments in water quality remediation at the basin or sub-basin scale as a means to increase water availability. The application of mathematical river water quality modelling, as a support tool to evaluate remediation options, is often limited by the availability of reliable data. Current proposals to use the River Wat...

In this study data of multifrequency, polarimetric and interferometric airborne “Experimental Synthetic Aperture Radar (E-SAR)” were evaluated and analysed to derive land use information, surface soil moisture, vegetation parameters and topographic information after a standardized processing scheme. The experiments were integrated in two projects of hydrologic and solute transport modelling and...

The Restionaceae species of the Fynbos biome is part of the Cape Floristic Kingdom is threatened by urbanization, agricultural expansion, groundwater extraction, and climate change. Therefore, it is necessary to assess and monitor the Restionaceae species under the impact of climate change. South Africa is a semi-arid environment, and hydrological factors are the main variables in the determina...

In response to the growing water crisis in Australia, the Bureau of Meteorology has been given a mandate to develop and maintain an integrated national water information system. Section 126 of the Commonwealth Water Act 2007 provides for the making of Regulations to support these functions, which came into effect on 30th June 2008. These regulations (BoM, 2008) define the requirements for the c...

Crop canopies and residues have been shown to intercept a significant amount of rainfall. However, rainfall or irrigation interception by crops and residues has often been overlooked in hydrologic modelling. Crop canopy interception is controlled by canopy density and rainfall intensity and duration. Crop residue interception is a function of crop residue type, residue density and cover, and ra...

This paper considers distributed hydrological models in hydrology as an expression of a pragmatic realism. Some of the problems of distributed modelling are discussed including the problem of nonlinearity, the problem of scale, the problem of equifinality, the problem o f uniqueness and the problem of uncertainty. A structure for the application of distributed modelling is suggested based on an...

Modelling rainfall-runoff processes in urban catchments has become an increasingly relevant issue, for instance to estimate the risk associated with urban flooding in densely populated areas. This needs hydrological models which, besides rainfall information, require good input data of detailed surface characteristics, such as imperviousness to accurately predict rainfall-runoff. One way to obt...

The present work has been carried out because nobody has done the hydrological properties assessment of the water of this Sawangi Nullah Dam, and to create the knowledge about the quality and potability of the water in the village people. This dam is situated near Hingna M.I.D.C. about 34 Kms from Nagpur city. The water samples were collected for a period of 12 months from June 2009 to May 2010...

Determining the spatiotemporal water quality patterns and their corresponding driving factors is crucial for lake water quality managements. This study analyzed hydrological data and concentrations of 11 water quality parameters, including total nitrogen, total phosphorus, ammonia nitrogen and chlorophyll–a (Chl–a), for water samples collected from 15 sampling sites between 2009 and 2014. The w...
