My friend and I are trying to find the surface area of a lake with calculus. The lake is an actual lake with very abnormal edges and deviations. We have a map with a drawing of the lake and some measurements but we don't know how to proceed. where is the Darcy flux [LT −1], q b is a specified rate source/sink [T −1], q e is the rate of water exchange between the subsurface and surface continua [T −1], ϕ is porosity [L 3 L −3], S w is water saturation [L 3 L −3], t is time [T], f a is the area fraction associated with each continuum [-], and f v is the volume fraction.

Thus, a lake may be surrounded with surface soil considerably more acid than the water. Such is the case around many lakes in the Adirondack mountains where most of the soils are strongly acid (Galloway et . a. By plotting the surface areas and volumes of Lake Buchanan at each 10 ft interval of lake level drop a correlation can be seen. Initially it was anticipated that although surface area and volume would have a linear relationship that at a certain lake level the surface would level off as the volume decreased because of a steeper channel at theFile Size: 1MB.

Recent advances in understanding the interaction of groundwater and surface water. because of the great increase in studies of the interaction of groundwater and surface water in landscapes other than riverine systems in the last 15 years. on Nearshore Habitats and Water Quality of Western Lake Erie, Journal of Great Lakes Research, Multivariate techniques, discriminant analysis, and WQI were applied to analyze a water quality data set including 27 parameters at 5 sites of the Lake Wular in Kashmir Himalaya from to to investigate spatiotemporal variations and identify potential pollution sources. Spatial and temporal variations in water quality parameters were evaluated through stepwise discriminant analysis (DA).Cited by:

The scatter in Figure 2 is likely related to uncertainty in lake‐surface area, as well as the distinction between snowmelt versus precipitation and precipitation‐runoff‐dominated lakes.

Surface area is determined by lake‐bed geometry and water level at the time of by: 2. Lake water temperature simulation model. Journal of Hydraulic Engineering, (11), in simulations on individual lakes, against gross lake properties such as surface area or Secchi depth.

Results of the deterministic lake water temperature stratification model using the functional relationships are not much different than results Cited by: water is referred to as consumed, because it is removed from the system. In some cases, this water consumption can be quite substantial.

AQUASTAT gathers country-level information about dams and reservoirs (see Section 2), but information about evaporation from artificial lakes and reservoirs is rarely reported. Due to itsFile Size: KB. Both sites are drainage lakes having distinct surface outlets and similar ratios of water-shed area/lake surface area and hydraulic residence time (Table I).

Previously, Grass Pond watershed was eval-uated with respect to the role of atmospheric sulphur deposition and sediment accumulation by Holdren et al.

A one-dimensional (1-D) physically based lake model was coupled to the Weather Research and Forecasting (WRF) model version developed by the National Center for Atmospheric Research to dynamically simulate physical processes of lakes and their effects on weather and climate at local and regional scales.

Our study area is focused on the Great by: Rivers, streams, ponds, lakes and swamps may seem full of water, but they hold only 3 percent of the planet's entire freshwater; 30 percent of that freshwater lies under the ground.

Because life on Earth needs freshwater to survive, it's important to find, use and maintain surface and subsurface water sources. If the elevation of the water surface of a lake is feet above sea level, what is the elevation of the water table at the lake.

View Available Hint(s) feet above sea level The elevation of the water table cannot be determined from this information. feet above sea level feet above sea level O. A model of glacial isostatic adjustment (GIA) is combined with GIS methods to predict the surface water history of the Great Lakes region of North America during the p years.

The extent of lakes continually changed as the Laurentide ice sheet margin fluctuated and GIA affected the elevations of Cited by: 6. The experimental model was used to generate the Lake Superior forecast and may later be used to create similar surface-water temperature forecasts for all five Great Lakes—possibly even.

Lake - Lake - Surface waves: Wind blowing over a calm lake surface first produces an effect that may appear as a widely varying and fluctuating ruffling of the surface.

The first wave motion to develop is relatively regular, consisting of small, uniformly developed waves called capillary waves. These are quite transient, dissipating rapidly if the wind dies away or developing to the more.

This book may be used for at least three different undergraduate courses including: 1. First course with an emphasis in surface water hydrology 2. First course with emphasis in groundwater hydrology 3. First course in hydrology with similar emphasis on ground and surface water by: 9.

Operational analyses of Lake Surface Water Temperature (LSWT) have many potential uses including improvement of numerical weather prediction (NWP) models on regional scales. In NovemberLSWT was included in the Met Office Operational Sea Surface Temperature and Ice Analysis (OSTIA) product, for lakes globally.

The Water Cycle - Water evapourates in the ocean and goes into the atmosphere. It then cools and becomes clouds. They then release moisture that comes down as rain or snow.

It melts or comes down and goes into lakes, rivers and into the ground to refill aquifers. Then it. Start studying science chapter 1 (water and atmosphere). Learn vocabulary, terms, and more with flashcards, games, and other study tools.

the small amount of the remaining water than runs off the surface of streams and lakes, most runoff seeps into groundwater. Calculating the size, or area, of a lake can be done a couple of different ways.

You can estimate the size by treating the lake as a the closest geometric figure, such as a circle, rectangle or triangle, or you can try to directly count the square footage of the lake by using graph paper on a scaled area map. The. of all outputs, A [L2] is the surface area of the lake, and dh/dt [L T−1] is the rate of water-level (h) change.

Note that A represents the water-covered area, which is normally dependent on h (the higher the water level, the greater the surface area). The water regime of a lake (i.e., how A and h change overFile Size: KB.

for to were analyzed to produce daily estimates of average surface water temperature for each lake. Results are compared to the long-term (28 year) mean annual cycle of average surface water tem-peratures.

The average surface water temperatures vary from as much as 4°C below climatology in to 2 to 3°C above climatology in Surface area also helps to keep the boat afloat. More surface area gives an object a better chance to displace enough water to offset its own weight.

For instance, a small ball of clay likely will sink before it can displace the amount of water equal to its weight. Lake - Lake - Currents: The principal forces acting to initiate water movements in lakes are those due to hydraulic gradients, wind stress, and factors that cause horizontal or vertical density gradients.

Lake water movement is usually classified as being turbulent. Hydraulic effects are frequently the result of inflows and outflows of water. The realistic simulations, in turn, consisted in modelling stream inflows in Toolik Lake during a storm event inwhen river water was colder than the lake surface.

In these simulations, the period of time simulated (which is referred to as the study period) started on dayand finished 20 days by:. To simulate effects of projected climate change on water temperature characteristics of small lakes in the contiguous U.S., a deterministic, one-dimensional year-round water temperature model is applied.

In cold regions the model simulates ice and snow cover on a lake.
