Recent studies have shown that stormwater control measures (SCMs) are less effective at retaining phosphorus (P) than nitrogen. We compared P retention between two urban/suburban SCMs and their adjacent free-flowing stream reaches at the Baltimore Long-Term Ecological Study (LTER) site, and examined changes in P retention in SCMs across flow by:

Due to the clarification of the demarcation mark between the SWC project and the adjacent Deep Bay Link project, the Assessment Area for the SWC was re-defined as the area below the high water mark. The terrestrial part of the area covered by the field surveys of the SWC project is re-named as Study Area, and the information collected in which.

Surface Water and Groundwater Interaction The larger-scale hydrologic exchange of groundwater and surface water in any landscape is controlled by: The distribution and magnitude of hydraulic properties (hydraulic conductivity, transmissivity and storativity) The geometry and position of the stream channel within the alluvial plain Ground water is present in virtually all landscapes.
The interaction of ground water with surface water depends on the physiographic and climatic setting of the landscape. For example, a stream in a wet climate might receive ground-water inflow, but a stream in an identical physiographic setting in an arid climate might lose water to ground water.

Figure 1. Ground water is the second smallest of the four main pools of water on Earth, and river flow to the oceans is one of the smallest fluxes, yet ground water and surface water are the components of the hydrologic system that humans use most.

A quantitative analysis of Cited by: The levels, speciation of elements, and toxicity of selected trace metals as well as other parameters in selected surface water, shallow groundwater sources, landfill leachate, and associated surface runoff in the Lake Victoria basin, Uganda, were studied.

This research investigates the nature and controls of surface water–groundwater interaction at the watershed scale, and investigates how mechanisms which control this interaction during baseflow conditions might best be represented within an integrated surface-subsurface numerical model.
The study site is the 46 km² Bertrand Creek Watershed, which is situated in a glaciated Cited by: 2. The evolution of hydraulic gradients in the center of the streambed from connection to disconnection. To derive our mathematical analysis methods, we develop a lab-scale stream-aquifer system as an example for explaining the evolution of hydraulic gradients under the streambed (Fig.

aritcle. However, in watersheds where ground water is expected to be the major source of nitrate (i.e., Morgan Cr., DR2, and Valley Cr., Fig.
4), nitrate concentrations were commonly lower in stream-bed pore water than groundwater or stream surface water during base-flow conditions (i.e., BFI values >Fig. Because much of the book focuses on water and its isotopes, we will demonstrate how to apply the Rayleigh equations by using the fractionations during water phase changes (i.e., during the condensation of vapor and the evaporation of water) as examples.

University of California, Water Resources Center, Report No. 77, p. All geomorphic features that retain water or promote hydrologic mixing with near-stream ground water increase the residence time, the volume of sediment in contact with dissolved nitrogen, and, consequently, dissolved nitrogen interaction with subsurface biota.
Further intensification of coordinated research was performed by the Assessment. The USGS also continues to monitor water quality at the Charleston gaging station on the San Pedro River as part of the National Water-Quality Assessment program.
The Partnership has recently committed significant funding to a comprehensive, multiple-year analysis of progress toward sustainable groundwater use in the by: 5. Globally, in –, satellite observations showed that human-built impervious surface areas (ie, excluding rocks and ice) covered approximately 1% of the land surface of the United States (83, km 2) and nearly % of the world (, km 2) (Palmer et al., ).This area is expected to triple by (Seto et al., ).For example, as shown in Fig.

Ground water quality is protected by Federal, State, local and tribal governments through rules and regulations aimed at managing these categories of contaminant sources.For channelized Incline Creek, the slope of the water surface is very low relative to both the shoreline and unmodified stream.
In the adjacent shoreline, the water table is lowered (drawn down) as a result of the incised channelized creek, so the inclination of the water table toward the lake is less than locations farther away from the by: 8.
