The parking lot of the Spenditall Megamall has an area of 128 ac. It is partially landscaped to provide some areas of grass. Assume that an average of 63% of the water that falls on the parking lot will flow into a nearby drainage ditch, and the rest either evaporates or soaks into unpaved areas. If as summer thunderstorm drops 3.23 cm of ran, how many cubic feet of water will flow into the drainage ditch?

  • Water Resources/Science

    The soil infiltration rate can be described by i (mm/h) = 2 t-0.5 + 4.0 (where t is in hour) Estimate the total runoff during the 9-hour period (hint: runoff only occurs after the surface is under ponding.

  • Bank Storage and Flooding

    Since groundwater moves significantly slower that surface runoff or surface water, this will create a lag time between a rainfall event and water entering the river.

  • Isotope Chemistry of Groundwater

    _________________________________________________________________________________________ Rainfall or any precipitation makes its way from the atmosphere and can either hit the ground surface, be intercepted by vegetation or canopy, or runoff from

  • Research Methods and Freshwater Organisms

    - Increase rainfall change the ph of the water causing the organisms that could not survive to die. Water runoff can move organisms away from resources in the habitat needed for survival.

  • Geology of a Region for Potential Aquifers

    The area of greatest concern is the recharge zone (e.g., the Edward's aquifer) where point and non-point source runoff readily infiltrates the porous rock and flows into the main water-yielding zones of the aquifer.

  • Landscapes Fshioned by Water

    With little vegetation to absorb this water, runoff is rapid, with mass movement (Stewart, 2005, URL: http://books.google.com/books?id=QIognFPkjXQC&dq=are+certain+climates+more+susceptible+to+mass+wasting).

  • Importance of Rainforest

    With deforestation, there will be a higher rate surface runoff and this results in a higher rate of soil erosion and soil leaching. In soil erosion, the topsoil is being removed or washed away by the higher surface runoff.

  • Erosion and Mass Wasting

    Rain can saturate soil and runoff at high velocities. Arid climate may experience mass wasting more because of the lack of plants to hold the soil in place. This is what happens following large fires.

  • Hypothesis Testing, Normality check & Regression Analysis

    The Article "Characterization of Highway Runoff in Austin, Texas, Area" (J. of Envir. Engr., 1998: 131-137) gave a scatter plot, along with the simple regression line, of X = rainfall volume (m3) and Y = runoff volume (m3) for a particular location.
