<p>Changes in land use are closely related to the increasing number of people who from time time. This change has an impact on runoff coefficient because rain that falls will not be retained or seep and flows directly into river. is what causes increase peak discharge a watershed. The purpose this study was determine magnitude changes occurred Serenan watershed 2015 2021 due use. method u...

This paper examines the determinants of the choice of financial advisors and their impact on the announcement effects of US acquirers in cross-border M&As. Two hypotheses are tested: one pertains to the acquiring firms’ home preference in selecting financial advisors, and the other relates to advisors’ experience in target countries. Evidence supports the home preference hypothesis in the selec...

[1] Based on the diffusion equation and Darcy’s law, Criss and Winston (2008b) developed the one-parameter analytical subsurface flow diffusion hydrograph model to represent the theory of rapid displacement of ‘‘old’’ aquifer water and shallow pore water following rainfall events. We developed a two-parameter analytical surface flow diffusion hydrograph model for urban or other basins that gene...

The empirical evidence overwhelmingly concludes that in most merger and acquisition transactions, the value created typically goes to the shareowners of the target companies, i.e. acquirers typically overpay. There are two major reasons for this. First acquirers overestimate the value of the target firm and/or the value of the synergies that they will add. Second the rewards of most acquirers’ ...

Chemical and isotope based hydrograph separation methods, such as end member mixing analysis (EMMA), have been utilized in recent decades because they offer a better explanation of stream chemistry than can be obtained from flow partitions derived using graphical or mathematical filter hydrograph partitioning techniques (Chapman and Maxwell, 1996; Pinder and Jones, 1969). However, use of such c...

computing or determining the amount of maximum flood debit in watershed is one of the main important parts of hydrological research in river improvement. in this regard it is necessary to be distinguished peak of flood flow and its hydrograph for favorable return period. this needs to have long time statistic and leminograph tools in study research area. in this study with the comparison of ava...

In this study, an Artificial Viscosity (AV) technique was developed for direct runoff calculation, instead of using the conventional Synthetic Unit Hydrograph (SUH) methods. We solved Shallow Water Equations (SWE) with second-order accurate Godunov finite volume model and fourth-order Runge-Kutta explicit scheme. The AV devised a Laplacian biharmonic operator, employed to solve convective terms...

This paper examines whether firms are able to use acquisitions ease their financial constraints. The results show that do financing constraints for constrained acquirers. Relative unconstrained acquirers, financially more likely undervalued equity fund and target liquid firms. Using a propensity score matched sample in difference-in-difference framework, the acquirers become less post-acquisiti...
