“…Initially, hydro-bio-geochemical work on rivers focused mostly on the concentrations of dissolved and particulate constituents and, when discharge rates were available, enabled calculations of fluxes and mass balances for entire catchments (e.g., Paces, 1985;Probst, 1986;Probst et al, 1992Probst et al, , 1995Ramanathan et al, 1994;Jing, 1995;Guieu et al, 1998;Chiffoleau et al, 1999;Freyssinet and Farah, 2000;Vörösmarty et al, 2000;Anderson and Dietrich, 2001;Grosbois et al, 2001;Oliva et al, 2004;Lafrenière and Sharp, 2005;Zakharova et al, 2005).…”

Research on rivers has traditionally involved concentration and flux measurements to better understand weathering, transport and cycling of materials from land to ocean. As a relatively new tool, stable isotope measurements complement this type of research by providing an extra label to characterize origin of the transported material, its transfer mechanisms, and natural versus anthropogenic influences. These new stable isotope techniques are scalable across a wide range of geographic and temporal scales. This review focuses on three aspects of hydrological and geochemical river research that are of prime importance to the policy issues of climate change and include utilization of stable water and carbon isotopes: (i) silicate and carbonate weathering in river basins, (ii) the riverine carbon and oxygen cycles, and (iii) water balances at the catchment scale. Most studies at watershed scales currently focus on water and carbon balances but future applications hold promise to integrate sediment fluxes and turnover, ground and surface water interactions, as well as the understanding of contaminant sources and their effects in river systems.

“…3A). According to Probst (1986), for most world rivers the model obtained for the relationship between [TSS] and Q ([TSS] = a.Q b ) presents positive b exponent with values between 1 and 2, indicating that the increase in [TSS] is a function of the discharge increase. This exponent in the model established for the Sorocaba River was 0.7039, indicating that the [TSS] was also influenced by rainfall.…”

“…Pioneering studies to investigate the nature and composition of the dissolved and suspended load transported by rivers were performed in the 1960-70s (Barth 1961, Johnson et al 1968, Gibbs 1970, Tardy 1971, Martin and Meybeck 1979). Since then, many studies have been carried out to assess chemical weathering and soil erosion rates using mass-balance models adjusted to atmospheric and anthropogenic (mainly originating from domestic sewage and industrial and agricultural activities) contributions, once the total river fluxes integrate the contributions of these different sources (Probst 1986, 1992, Meybeck 1987, Lasaga et al 1994, White and Blum 1995, Boeglin and Probst 1996, 1998, Boeglin et al 1997, Gaillardet et al 1999, Semhi et al 2000, Millot et al 2002, Meybeck et al 2003, Walling and Fang 2003, Riebe et al 2004, Chakrapani 2005, Weijden and Pacheco 2006, Louvat et al 2008, Gurumurthy et al 2012, Laraque et al 2013, Li et al 2014. The interest in assessing the chemical weathering and soil removal rates in watersheds under different geological and climatic setting also occurred in Brazil (Stallard and Edmond 1981, 1983, 1987, Moreira-Nordemann 1980, 1984, Gaillardet et al 1997, Bortoletto Junior et al 2002, Conceição and Bonotto 2003, Mortatti and Probst 2003…”

Chemical weathering and soil removal rates are responsible for the Earth's landscape, composition of surface and groundwater, producing the soils and buffering the composition of the atmosphere. This study aimed to assess the chemical weathering and soil removal rates in the Sorocaba River basin, São Paulo State, Brazil, allowing answering the questions about the dynamics of fluvial transport of dissolved and suspended solids, the chemical weathering processes and associated atmospheric/soil CO 2 consumption, and the relationship between chemical weathering and soil erosion rates. The annual specific flux of total suspended solids and total dissolved solids were 49.59 and 60.97 t/km 2 /yr. The chemical weathering process dominant in the Sorocaba River basin was the monosiallitization (RE = 2.4), with an associated atmospheric/soil CO 2 consumption of 2.3 × 10 5 mol/km 2 /yr. The chemical weathering and soil removal rates were 7.2 and 29.8 m/Myr, respectively, indicating a soil thickness reduction. Finally, the soil removal rate in the Sorocaba River basin is almost 3-fold higher than the Cenozoic soil removal rates, being this difference related to the current land use which increased the soil removal processes.

“…SSC values estimated from turbidity measurements (SSC est ) were multiplied with flow to obtain instantaneous loading rates. We estimated total suspended sediment yield by integrating instantaneous loads over the period of record using the partial balance method (Probst, 1986). In the CC watershed, the estimated sediment yield included positive loads (sediment export) and negative loads (sediment import) associated with backwater events.…”

Many small streams in coastal watersheds in the southeastern United States are modified for agricultural, residential, and commercial development. In the South Carolina Lower Coastal Plain, low‐relief topography and a shallow water table make stream channelization ubiquitous. To quantify the impacts of urbanization and stream channelization, we measured flow and sediment from an urbanizing watershed and a small forested watershed. Flow and sediment export rates were used to infer specific yields from forested and nonforested regions of the urbanizing watershed. Study objectives were to: (1) quantify the range of runoff‐to‐rainfall ratios; (2) quantify the range of specific sediment yields; (3) characterize the quantity and quality of particulate matter exported; and (4) estimate sediment yield attributable to agriculture, development, and channelization activities in the urbanizing watershed. Our results showed that the urban watershed exported over five times more sediment per unit area compared with the forested watershed. Sediment concentration was related to flow flashiness in the urban watershed and to flow magnitude in the forested watershed. Sediments from the forested watershed were dominated by organic matter, whereas mineral matter dominated sediment from the urban stream. Our results indicated that a significant shift in sediment quality and quantity are likely to occur as forested watersheds are transformed by urbanization in coastal South Carolina.
