Evaluation of a method of estimating low-flow frequencies from base-flow measurements at Indiana streams. Indianapolis, Ind.: U.S. Dept. of the Interior, U.S. Geological Survey ; Denver, CO: Branch of Information Services [distributor], (OCoLC) Material Type: Government publication, National government publication: Document Get this from a library! A practical method of estimating peak from mean daily flows with application to streams in Ontario. [B P Sangal; National Hydrology Research Institute (Canada); Canada. Inland Waters Directorate.] -- "A practical method has been suggested for estimating peak flow. The method uses variables that are the mean daily flows of three consecutive days, with the maximum mean   High-flow sampling also results in the smallest RMSPE values for all methods used for NO23, TP and SSC. High-flow and seasonal sampling improve the performance of some methods over uniform sampling for SC and TN, although most method estimates for these constituents are within 5 percent of observed decadal loads regardless of ://   of stream with the most even cross-sectional area. STEP 3: Calculate the flow in litres per second The flow is the product of the average stream area and the average velocity of the flow: Since the water moves more quickly on the surface than in other parts of the stream, an additional factor must

A drainage-area ratio method was developed to estimate peak-flow magnitude and frequency rela-tions for ungaged sites near gaging stations on gaged ://   for estimating streamflow statistics such as flow-duration exceedances, and helps water managers to understand the natural flow regime of a stream, which is critical to the sustainability and health of aquatic freshwater ecosystems (Vogel et al. , Poff and Zimmerman ). USGS, in cooperation with The /Research/Environmental/   Overview of NSSThe U.S. Geological Survey (USGS) develops and publishes regression equations for estimating streamflow statistics for every State, the Commonwealth of Puerto Rico, and a number of metropolitan areas in the United States. These equations have been compiled into the National Streamflow Statistics (NSS) Program. The NSS program should be useful to engineers,   Float-Area Method The amount of water passing a point on the stream channel during a given time is a function of velocity and cross-sectional area of the flowing water. Q = AV where Q is stream discharge (volume/time), A is cross-sectional area, and V is flow velocity You need: tape measure watch or
