1 Stream Assessment and Discharge and Channel Measurements Objective: Learn how to measure the velocity, discharge and cross-sectional area of small streams. You will compare two methods of measuring discharge (Q = AV): current meter and float method. Learn how to look for macroinvertebrates and how to characterize channel substrate. Background: An understanding of how water flows is important for understanding how activities in the channel and watershed affect flow. 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 (1) where Q is stream discharge (volume/time), A is cross-sectional area, and V is flow velocity. Equation 1 is a form of a mass-balance equation typically referred to by hydrologists as the Continuity Equation. If you change the cross-sectional area, but have to pass the same discharge, Eqn 1 shows that flow velocity must increase to maintain continuity. An increase in velocity results in an increase in the energy in the flow. This means that the flow can do more work, such as erosion and transport of sediments. METHODS Discharge Measurements: 1. Float method inexpensive and simple. This method measures surface velocity. Mean velocity is obtained using a correction factor. The basic idea is to measure the time that it takes the object to float a specified distance downstream. V surface = travel distance/ travel time = L/t Because surface velocities are typically higher than mean or average velocities V mean = k V surface where k is a coefficient that generally ranges from 0.8 for rough beds to 0.9 for smooth beds (0.85 is a commonly used value) Step 1. Choose a suitable straight reach with minimum turbulence (ideally at least 3 channel widths long) Step 2. Mark the start and end point of your reach Step 3. If possible, travel time should exceed 20 seconds. Step 4. Drop your object into the stream upstream of your upstream marker. Step 5. Start the watch when the object crosses the upstream marker and stop the watch when it crosses the downstream marker. Step 6. You should repeat the measurement at least 3 times and use the average in further calculations. Step 7. Measure the cross-sectional areas at the start and end point of your reach. Use the water width and multiply it by the average depth as computed from 3 or 4 depth measurements made across the channel. Average your cross-sectional areas: Using the average area and corrected velocity, you can now compute discharge, Q. Correction factors to convert surface velocity to average velocity typically range from Many times 0.85 is used. In mountain streams with lots of roughness elements, the value may be much lower e.g. ~ With an estimate of cross-sectional area, discharge can be computed as Q = VA where V is average velocity

2 2. Velocity meter- We will be using a Swoffer meter: a propeller type meter similar to an anemometer. When using a current meter, the stream is divided into small sections perpendicular to the streamflow and velocity and depth are measured in each section. The subsection area extends laterally from half the distance from the proceeding observation vertical to half the distance to the next (see diagram below). The width of the subsections can be variable across the cross-section. The width of each subsection is calculated by subtracting the distance to the previous vertical from the distance to the next vertical, then dividing by 2. Ideally, the stream is divided into sections so that no more than 5-10% of the discharge flows through any subsection. Think about the figures shown in lecture and in your text. In practice, depth and velocity measurements are taken at up to 20 points along a cross section in the field while the sub-sectional widths, areas and discharges are calculated later by hand or with a spreadsheet (See example calculation below). Although the number of points will vary with stream width, desired accuracy, and available time. 0.2d and 0.8d The mean velocity is assumed to be 0.4 d from the bottom (or 0.6d from the water surface). In deeper streams (> 2.5 feet) you should take a velocity reading at 0.2d and 0.8d and then average those to get mean velocity in a section. For this lab, just take the one measurement at 0.6 d at each section across the stream. Q = stream discharge (Volume/time) V = stream velocity A = cross-sectional area W = top width BFW = bank fullwidth S = water slope (often assumed to be same as channel bed slope)

3 Example calculations for the flow meter discharge method: You enter data in columns 2 (initial distance), 3 (depth) and 5 (velocity). Set up formulas in the spreadsheet to fill in Interval width, area, Q interval and % total flow. W=(12-9)/2 Multiply W=(20-18)/2 W=( )/2 Sum Stream Width The width of the river must first be found. This can be done using the same tape along which you took the velocity meter measurements. T The start and finishing points for the measuring are the points at which the dry bank meets the water.. The zero point does NOT need to be at the river s edge, it can be up on the bank. Just record where the where starts and stops and do the math to get wetted width. The ends of the measured section should be determined by observation from directly above the tape at 90 to the ground. Observation from directly above the tape ensures that the margin of error is kept at a minimum. It is possible that the river or stream only occupies part of the whole channel, and that in flood conditions the river expands and currently dry bank areas become part of the channel. If you wish to include a prediction of the river's characteristics when in flood you will need to also measure the bankfull width. Bankfull Width The start and finishing points for measuring are the points where the vegetation and gradient of the bank suggest that the river has reached its maximum capacity. If the water were to rise above these points flooding of the surrounding area would occur. The tape distances between the two edges of bankfull width are determined by observation from directly above the tape at 90 to the ground. Observation from directly above the tape ensured that the margin of error was kept at a minimum.

4 Benthic Invertebrates At the stream in St. Edwards and at Juanita Creek, we will use a kitchen sieve to collect insects. One can also pick up cobbles (medium sized rocks) from the stream and look for invertebrates. Caddis flies will be in little rock tunnels. Mayflies and stoneflies will scurry across the rock. Use the field guide in your lab packet. Substrate At the site where you take your velocity-area discharge measurement, estimate the substrate coverage by category for the stream area extending 1 m upstream from your cross-section. If you have chosen a good site for discharge measurement this should be a riffle. Estimate the area of a near-by pool and estimate the substrate coverage by category for the pool. Substrate size categories Substrate 1- Sand, silt, clay. [<0.25" or <0.8 cm (smaller than pea size)] 2- Small Gravel [0.25"-1" or > cm (pea to golf-ball size)] 3- Large Gravel [>1" - 3" or > cm (golf-ball to baseball size)] 4- Small Cobble [>3"-6" or > cm (baseball to cantaloupe size)] 5- Large Cobble [>6"-12" or >15-30 cm (cantaloupe to basketball size)] 6- Small Boulders [>12"-40" or >30cm-1.0 m (basketball to car-tire size)] 7- Large Boulders [>40" or >1.0 m (greater than car-tire size)] 8- Bedrock
