“…It performs a mass balance of flow and water qualities sequentially down a river system. Its structure takes account of inputs from tributaries, groundwater and effluent discharges, and allows for abstractions, chemical decay processes and biological behavior along the river [44].…”

“…As a dynamic model, QUASAR seems to be well suited for modeling large freshwater river systems provided there are sufficient data [3]. There has been a range of model applications such as: the river Pelenna (in Wales, UK) to assess heavy metal pollution [46], the river Thames (UK) to assess the movement and distribution of nitrates and algae along the Fiver system [47], for modeling impacts of land use and climate change on nitrate-nitrogen in UK [44] and for land ocean interaction study [48].…”

The review discusses six major public domain water quality models currently available for rivers and streams. These major models, which differ greatly in terms of processes they represent, data inputs requirements, assumptions, modeling capability, their strengths and weaknesses, could yield useful results if appropriately selected for the desired purposes. The public domain models, which are most suitable for simulating dissolved oxygen along rivers and streams, chosen in this review are simulation catchment (SIMCAT), temporal overall model for catchments (TOM-CAT), QUAL2Kw, QUAL2EU, water quality analysis simulation program (WASP7), and quality simulation along rivers (QUASAR). Each of these models is described based on a consistent set of criteria-conceptualization, processes, input data, model capability, limitations, model strengths, and its application. The results revealed that SIMCAT and TOMCAT are over-simplistic but useful to quickly assess impact of point sources. The QUAL2Kw has provision for conversion of algal death to carbonaceous biochemical oxygen demand (CBOD) and thus more appropriate than QUAL2EU, where macrophytes play an important interaction. The extensive requirement of data in WASP7 and QUASAR is difficult to justify the time and costs required to set up these complex models. Thus, a single model could not serve all wide range of functionalities required. The choice of a model depends upon availability of time, financial cost and a specific application. This review may help to choose appropriate model for a particular water quality problem.

“…Loss of nitrate-nitrogen (NO 3 -N) has particular implications for site fertility, and may also result in increased N loading in the hydrologic system. Ferrier et al (1995) found that NO 3 -N levels increased with changing agricultural patterns and highlighted the importance of those changes in the River Don system, North East Scotland, UK. Metzger et al (2008) described a quantitative vulnerability assessment of ecosystem service change in Europe based on land use changes.…”

Impact of land use changes on water quality in headwaters of the Three Gorges Reservoir

The assessment of spatial and temporal variation of water quality influenced by land use is necessary to manage the environment sustainably in basin scales. Understanding the correlations between land use and different formats of nonpoint source nutrients pollutants is a priority in order to assess pollutants loading and predicting the impact on surface water quality. Forest, upland, paddy field, and pasture are the dominant land use in the study area, and their land use pattern status has direct connection with nonpoint source (NPS) pollutant loading. In this study, two land use scenarios (1995 and 2010) were used to evaluate the impact of land use changes on NPS pollutants loading in basins upstream of Three Gorges Reservoir (TGR), using a calibrated and validated version of the soil and water assessment tool (SWAT) model. The Pengxi River is one of the largest tributaries of the Yangtze River upstream of the TGR, and the study area included the basins of the Dong and Puli Rivers, two major tributaries of the Pengxi River. The results indicated that the calibrated SWAT model could successfully reproduce the loading of NPS pollutants in the basins of the Dong and Puli Rivers. During the 16-year study period, the land use changed markedly with obvious increase of water body and construction. Average distance was used to measure relative distribution patterns of land use types to basin outlets. Forest was mainly distributed in upstream areas whereas other land use types, in particular, water bodies and construction areas were mainly distributed in downstream areas. The precipitation showed a non-significant influence on NPS pollutants loading; to the contrary, interaction between precipitation and land use were significant sources of variation. The different types of land use change were sensitive to NPS pollutants as well as land use pattern. The influence of background value of soil nutrient on NPS pollutants loading was evaluated in upland and paddy field. It was found that total nitrogen (TN) and total phosphorous (TP) in upland were more sensitive to NPS pollutants loading than in paddy fields. The results of this study have implications for management of the TGR to reduce the loading of NPS pollutants into downstream water bodies.

“…Others examined the impacts of land use on only the quantity or the quality aspect of runoff. Examples of such work include those performed by Meissner et al (1999), Ferrier et al (1995), Tsihrintzis and Hamid (1998), Mattikalli and Richards (1996), Wu and Haith (1993), Hulme et al (1993), Henderson-Sellers (1994), and Bouraoui et al (1998). Only a few studies have employed an integrated approach involving the use of statistical and spatial analyses, as well as hydrologic modeling to examine the hydrologic effects of land use in both a regional and a local scale.…”
