Using OTIS to model solute transport in streams and rivers
Solute transport in streams and rivers is governed by a suite of hydrologic and geochemical processes. Knowledge of these processes is needed when assessing the fate of contaminants that are released into surface waters. The study of solute fate and transport often is aided by solute transport models that mathematically describe the underlying processes. This fact sheet describes a model that cons

Analysis of 20th century rainfall and streamflow to characterize drought and water resources in Puerto Rico
During the period from 1990 to 1997, annual rainfall accumulation averaged 87% of normal at the 12 stations with the longest period of record in Puerto Rico, a Caribbean island with a 1999 population of 3.8 million. Streamflow in rivers supplying the La Plata and Loíza reservoirs, the principal water supply of the San Juan metropolitan area, was at or below the 10th flow percentile for 27% to 50%

Primary food resources in the Sacramento-San Joaquin Delta
The Sacramento-San Joaquin River Delta, a complex mosaic of tidal freshwater habitats, is now a focus of ecosystem rehabilitation because of changes in critical functions associated with its geographic location at the landestuary interface. One of these functions is the production, transport, and transformation of organic matter that constitutes the “primary food supply,” that is, the food supply

A strategy for a stream-gaging network in Maryland
Water is a keystone resource. In abundance, it
supplies cities, industries, and agriculture. To
maintain healthy natural and human ecosystems,
water must not only be present in adequate
quantity, but it must be of suitable quality for its
intended use. Water quality depends on the
amount, or load, of contaminants, both natural and
anthropogenic, that it contains. Accurate
assessment of these conta

Equations for estimating Clark unit-hydrograph parameters for small rural watersheds in Illinois
Equations for estimating the time of concentration (TC) and storage coefficient (R) of the Clark unit-hydrograph method were developed for small rural watersheds [0.02–2.3 square miles (mi2)] in Illinois. The equations will provide State and local engineers and planners with more accurate methods to estimate the TC and R for use in simulating discharge hydrographs on small rural watersheds when de

Dissimilatory reduction of selenate and arsenate in nature
This chapter discusses the biogeochemical reduction of selenate (Se(VI)) and arsenate (As(V)) when they enter anoxic environments and are used as electron acceptors for the oxidation of organic matter. These reductions are of a dissimilative nature and support the anaerobic growth of selected bacteria which conserve energy from this process. The chapter summarizes what is known about the bacteria'
