Delumyea and McCleary report data for the determination of %w/w organic material in sediment samples collected at different depths from a cove on the St. Johns River in Jacksonville, FL. After collecting the sediment core it was sectioned into a set of 2-cm increments. Each increment was placed in 50 mb of deionized water and the slurry filtered through a piece of preweighed filter paper. The filter paper and sediment increment were then placed in a preweighed evaporating dish and dried in an oven at... 

The General Electric in-duct scmbbing (IDS) process involves the atomization of a slaked lime slurry, using a rotary disk atomizer A test at the 12 MWe scale at the Muskingum River Station of Ohio Power, performed in a duct with a 4.3-m cross section, achieved 50% SO2 removal with good lime utilization... 

Cathodic protection of water power turbines is characterized by wide variations in protection current requirements. This is due to the operating conditions (flow velocity, water level) and in the case of the Werra River, the salt content. For this reason potential-controlled rectifiers must be used. This is also necessary to avoid overprotection and thereby damage to the coating (see Sections 5.2.1.4 and 5.2.1.5 as well as Refs. 4 and 5). Safety measures must be addressed for the reasons stated in Section 20.1.5. Notices were fixed to the turbine and the external access to the box headers which warned of the danger of explosion from hydrogen and included the regulations for the avoidance of accidents (see Ref. 4). 

As mentioned in Section 1.1.4, bacterial action on river water can also produce methane.

Parker (1975), Lees (1980), Gugan (1978), and Sad e et al. (1976, 1977) have described extensively the vapor cloud explosion that occurred in the reactor section of the caprolactam plant of the Rixborough Works on June 1,1974. The nixborough Works is situated on the east bank of the River Trent. The nearest villages are Rixborough [800 meters (one-half mile) away], Amcotts [8(X) meters (one-half mile) away], and Scunthorpe [4.9 km (approximately three miles) away].

The primary industries are pulp and paper, lumber, electronics, and tourism. The basin supports extensive wildlife and fish habitat. Precipitation varies from 100 cm at the basin floor to more than 300 cm in the Cascade Range and summers are dry and warm with winters cloudy and wet. Daily average temperatures in the basin range from 1.7 C in winter to 28°C in summer. A cross-sectional profile of the basin is shown in Figure 2A. Figure 2B identifies specific morphological reaches of the main stem Willamette River.

In addition to runoff, rivers transport products of upland weathering to the oceans, forming a key link in the tectonic cycle of uplift and erosion. This interaction will be explored further in Section 6.6. 

A simple model can be used to describe this control of the concentration. In this model the input is from rivers and the output is uptake by reactions in the ocean crust under hydrothermal systems. (An application of this model is given in Section 13.5). Thus... 

All the factors mentioned in the previous sections play a role in the movement of metals through their overall biogeochemical cycle injection into the atmosphere, deposition onto land or water surfaces, transport via rivers and... 

In this section, an overview of the net transport of metals through rivers, estuaries, and the oceans provides an example of how these chemical and physical forces interact. 

Referring to the discussion of the fundamental concepts regarding half cells and the Nernst equation in Chapter 5 (Section 5.3.1) it is possible to briefly summarize the similarities and differences of these two sets of systems. It is important to recognize the ways in which they are different when considering the behavior of complex multivariate systems such as the oceans and clouds, or a lake-river system. 

It might be derived from previous suggestions that the river sections below dams can experience even higher stress than those upstream. In the case of the Ter River (NE Spain) during the unusually dry 2007-2008 period, differences were not high... 

Inputs of organic matter and nutrients, benthic metabolism, and nutrient retention at each stream section depend on diffuse and point sources. Yet, under low flow conditions, water and matter transport downstream becomes impeded or discontinued due to stream contraction and fragmentation during dry periods. Therefore, nutrient export from rivers in semiarid regions will depend, more so than in more humid regions, on the interplay between the spatial configuration of organic matter...
