Incorporating seepage losses into the unsteady streamflow equations for simulating intermittent flow along mountain front streams

摘要: [1] Seepage losses along numerous mountain front streams that discharge intermittently onto alluvial fans and piedmont plains are an important source of groundwater in the Basin Range Province Western United States. Determining distribution seepage loss is when assessing resources region. Seepage a stream northern Nevada was evaluated using one-dimensional unsteady streamflow model. incorporated into spatial derivatives equations. Because from dependent on depth, wetted perimeter, streambed properties, two-dimensional variably saturated flow model used to develop series relations between depth for each reach. This method works separated by sediment. Two periods intermittent were simulated evaluate modeling approach. The reproduced measured channel. spring 2000 limited upper reaches plain totaled 196,000 m3, whereas 64% 2004 occurred at base 273,000 m3. A greater attributed increased hydraulic conductivity caused less armoring approach provides quantifying distributing cross or plains.
