  1. Integrated hydrological and hydrodynamic modeling study has been conducted to investigate hurricane impact on Woonasquatucket River, Rhode Island, USA. Model simulation was conducted for the case study of 2010 storm event. The hydrological model simulates the runoff from the heavy rainstorm, while the river hydrodynamic model simulates the flood waves affected by the interactions of upstream rainfall runoff and downstream storm surge. Results indicate that the river floods was dominant by rainfall runoff in upper river reaches, but dominant by storm surge in the lower river area near the estuary

  2. Necessary and sufficient conditions are provided for a class of warped product manifolds with non-vanishing flux to be supersymmetric solutions of 11D supergravity. Many non-compact, but complete solutions can be obtained in this manner, including the multi-membrane solution initially found by Duff and Stelle. In a different direction, an explicit 5-parameter moduli space of solutions to 11D supergravity is also constructed which can be viewed as non-supersymmetric deformations of the Duff–Stelle solution.

  3. A one-parameter family of coupled flows depending on a parameter $$\kappa>0$$ is introduced which reduces when $$\kappa=1$$ to the coupled flow of a metric $$\omega$$ with a $(1,1)$-form $$\alpha$$ due recently to Y. Li, Y. Yuan, and Y. Zhang. It is shown in particular that, for $$\kappa\not=1$$, estimates for derivatives of all orders would follow from $C^0$ estimates for $$\omega$$ and $$\alpha$$. Together with the monotonicity of suitably adapted energy functionals, this can be applied to establish the convergence of the flow in some situations, including on Riemann surfaces. Very little is known as yet about the monotonicity and convergence of flows in presence of couplings, and conditions such as $$\kappa\not=1$$ seem new and may be useful in the future.
