A widely used procedure for estimating surface runoff in small watersheds is the curve number method (CN) (USDA) which is used in various hydrological models, water erosion estimation and contaminant generation and transport models. Due to its empirical nature, it is necessary to have calibrated ...
Other researchers also found that the land use types with high CN values are mainly urban area, farmland and water bodies, Conclusion The Curve Number approach is an effective, simple and widely used method to estimate surface runoff volume. The revised CN values calculated by using monitoring ...
Model always gives higher values than the measured values because the model estimates grass runoff but it is not all runoff that reaches the watershed outlet, as a fraction of it is trapped by ponds and water bodies. In this study, predicated runoffs were found higher than the measured ...
It’s long been known that compound has issues with universality, number four on the list above. Compound archery remains popular in North America and Europe, with smaller pockets of competitors, elite and recreational, spread unevenly around the rest of the world. Again much progress has been ...

A large number of field practices show that the water flooding characteristic curve will appear up-warping phenomenon in ultra-high water cut stage, and the conventional water flooding characteristic curve is difficult to accurately characterize. In this work, a new expression of oil–water relative...

The equations proposed may be applied for approximation of the rheological properties of viscoplastic bodies in discussing three-dimensional deformation (flow) problems. The determination of the yield stress in two (or three-) dimensional deformations is not trivial, especially for Hershel-Bulkley liquid...
This information is useful although the coyote hunts for the mouse, but later (considering the large number of bushes in the coyote’s world), it is probably not helpful. The same coyote may remember the location of a stream where it drinks; the water remains in the same location and a ...
