Full textIn the majority of rainfall-runoff modelling applications, the objective function to be minimised in the parameterisation procedure is based on a measure of the goodness-of-fit that maximized the fit of the simulated data to the overall observed data, taking partially into account the specific model applications. The present dissertation focuses on the development and testing of an objective function based on the expected utility of the rainfall-runoff model. The method is based on the evidence that the performances of a hydrological model closely depend on the purpose of the application. For istance, the simulated data caught have different utility in a water resources management system or in a flood forecasting system. In the proposed method, at each time step, the comparison between simulated and observed data is carried out by using an “ad-hoc” utility function. The calibration is performed by maximizing the overall estimated utility of the simulated data. Different utility functions are tested and the results are compared against those obtained with traditional procedure. The results reveal that an adequate utility function allows an improvement of the model performances in the reproduction of the discharges considered most important to the purpose of the modeling application.

Full textBlack holes (BHs) are variegated and fascinating objects in Nature. Their realm extends from the stellar BHs with mass $sim 10-10^2 msun$ to the supermassive BHs of $10^{9-10} msun$ that reside in the center of galaxies. While the former are the expected outcome of stellar evolution, the latter are the results of multiple dark matter halo mergers in the standard $Lambda$CDM scenario. When two BHs are close enough, they form a binary BHs (BHBs) and emit gravitational waves (GWs) that we can detect with our inteferometers. Similarly to BHs, also BHBs can be divided into different sub-populations, each with its unique features and characteristics: stellar BHBs (SBHBs) form from the co-evolution of binary stars or in dense region, while massive BHBs (MBHBs) are the result of galaxy mergers. The challenges of GW astronomy are still numerous and require different knowledge and expertise to be solved. For this reason, I start this Thesis presenting result for SBHBs in the initial chapters and moving to MBHBs in the end. Each chapter has its own brief introduction and discussion of the main results and conclusions. In Chapter 1 I introduce some basic General Relativity (GR) concepts related to the emission of GWs. I summarise the current status of GW astronomy. I explain how GWs from BHBs can be easily modeled under some reasonable assumptions and report some formulas useful to understand the concepts of the following chapters. In Chapter 2 I study the minimum Post-Newtonian (PN) order necessary to accurately track SBHBs in LISA and perform an unbiased parameter estimation. SBHBs are expected to spend a large number of cycles in band, therefore an accurate waveform is necessary to avoid biases in the binary parameters. I show that the main factor affecting the PN accuracy is the time to coalescence with systems closer to merger requiring higher PN contributions. I apply the previous result to a realistic population of SBHBs in LISA in order to draw more realistic estimates: I find that most of the sources can be modeled with just 2PN corrections while systems merging during LISA time mission require up to 2.5PN and 3PN contributions. The topic of Chapter 3 is a model to describe SBHBs above the pair-instability mass gap, i.e. BHs with mass $> 120 msun$. I build a simple approach and, under the assumption that the binary formation does not change beyond the mass gap, I estimate the detected rate for current detectors, ET and LISA. Finally I also suggest the possibility that the undetected sources form a new source of stochastic background in LISA. In Chapter 4 I move to MBHBs, detectable only from space by LISA. I provide an introduction on MBHBs formation and evolution and the multimessenger possibilities. I also explain how we estimate source information with the so-called Fisher matrix formalism. In Chapter 5 I present a work I contributed where we explore the possibility to detect a Doppler modulated X-ray emission during the inspiral of MBHBs. In the last stage of merger, X-ray emission is expected as the result of gas accretion on each BHs and the orbital motion of the binary might imprint a Doppler modulation on the electromagnetic (EM) emission in phase with the GW signal. The detection of this modulation would allow to pinpoint the exact source location in the relatively large error area provided by LISA. From our analysis, we estimate few modulation detections over LISA time mission. Finally in Chapter 6 I report the results for the parameter estimation of MBHBs on the fly, i.e. as function of time before coalescence. In particular I focus on sky position, luminosity distance, chirp mass and mass ratio and how their errors decrease as the system approaches merger. For the benefit of the community, I release also the complete set of data and analytical fits to describe the time evolution in the aforementioned parameters. Finally I discuss the multimessenger prospects.
