Hydraulic Character of Discharge Hydrograph for Tunneling

Estimation of aquifer lower layer hydraulic conductivity values through base flow hydrograph rising limb analysis

[1] The estimation of catchment-averaged aquifer hydraulic conductivity values is usually performed through a base flow recession analysis. Relationships between the first time derivatives of the base flow and the base flow values themselves, derived for small and large values of time, are used for this purpose. However, in the derivation of the short-time equations, an initially fully saturate...

Schwinger Tunneling and Thermal Character of Hadron Spectra

It is shown that an oscillatory character of the solutions of the collisionless kinetic equations describing production of the quark-gluon plasma in strong color fields leads to the exponential (thermal-like) transversemomentum spectra of partons produced in the soft region (100MeV < p⊥ < 1GeV). In addition, the production of partons in the very soft region (p⊥ < 100MeV) is clearly enhanced abo...

Free-surface flow simulations for discharge-based operation of hydraulic structure gates

We combine non-hydrostatic flow simulations of the free surface with a discharge model based on elementary gate flow equations for decision support in operation of hydraulic structure gates. A water level-based gate control used in most of today’s general practice does not take into account the fact that gate operation scenarios producing similar total discharged volumes and similar water level...

Synthetic Unit Hydrograph Methods: A Critical Review

The present study critically reviews the synthetic unit hydrograph (SUH) methods available in hydrologic literature. The study reveals that the traditional methods of SUH derivation, e.g., Snyder, SCS, traditional methods like Snyder and TS method that does not yield satisfactory results, and their application to the practical engineering problems is tedious and combursome. On the other hand, p...
