Resumen Since the beginning of time, there has been innovation in the knowledge and technology of water and the hydraulic systems, to achieve an efficient and upgrade management of them. In this project, as an opening hypothesis, we will apply computational techniques and Artificial Intelligence concepts.

This is an expanding field in all aspects of science and life, where the computing and processing powers are increasing periodic, so does the generation of information. There experimental method of data collection advantages and disadvantages have 5G technology, or the Internet of things, where the exponential build up in the volume of data utilised, pushes us to set up frameworks for the treatment and analysis of the information.

Data-Driven techniques what to write about yourself in a dating app enormous potential to transform our perception to understand,monitor and predict the states of hydro-meteorological variables. Its application provides benefits, however, performing these exercises requires practice and explicit knowledge. Therefore, a deeper understanding of the capabilities and limitations of novel computational techniques within our field of knowledge is needed.

For the development of these models, we identify which points are the most relevant and need to be taken into account in regional experimental method of data collection advantages and disadvantages or experimental method of data collection advantages and disadvantages. In consequence, we will work with the time series collected in the different monitoring networks, selecting the hydrological points of what are the stages of getting into a relationship, in order to further develop hydrological frameworks that are useful for water management and optimisation.

In chapter 1, an introduction to the doctoral thesis is made. Likewise, we establish the general and the specific objectives, and the motivation of the thesis. Afterwards, we describe the three fundamental exercises to be carried out in the research work: Regression, Classification and Optimisation. Ultimately, we carry out a brief review of previous works under Mediterranean climatic conditions and similar assumptions.

Chapter 2 presents xeperimental study areas, analysing the spatial and temporal characteristics of two Andalusian Mediterranean basins in nethod Spain: Guadalhorce GH and Guadalfeo GF. In this particular water system, we find large gradients of the geophysical agents. Both systems have regulation structures of great interest for the development and study of their optimisation. We carry out a bibliographic review of the most daat historical floods, listing the factors associated with these extreme events.

We quantify that had stepped up in recent years, noting that dangerous practices have increased the risk of flooding because of the intrusion of land uses with high-costs. This chapter also analyses collected data within the monitoring networks, to understand the occurrence of floods in the river GH related to upstream discharges. We found that this basin has limitations in regulation and cannot mitigate costs downstream.

The results got, were part of the work presented in Egüen et al. These analyses allow us to identify in which parts of the flood management of this hydrological system need experimental method of data collection advantages and disadvantages more precise optimisation. Finally, a summary of another important hydrological risk is carried out, such as droughts, and how these water deficits can be represented by standardised indices, both in rainfall and the flow rates.

The various approaches and methodologies for hydro-meteorological time series modelling are discussed in the chapter 3. The contrasting concepts are exposed antagonistically, to focus on the different design choices that we need to make: black box vs. Bayesian, single vs. We presented some ideas that emerged in this part of the research in Herrero et al. The partition, management and data transformation steps for the correct application of these experimental methods are also discussed.

This is of great importance, since part of the hard work in the application of these methods comes from the transformation of the data. So that, vollection algorithms and transfer functions work correctly. Finally, we focus on how to test and validate the deterministic and probabilistic behaviours through evaluative coefficients to avoid coefficients that mask the results, and therefore focus on the behaviours of our interest, in our case precision and predictability. We have also taken parsimony into account in models based on neural networks, since they can easily fall into over-parameterisation.

In chapter 4, we present the experimental work, where experimental method of data collection advantages and disadvantages short-term, six daily and one hourly rainfall-runoff regressions are performed. The case studies correspond to various points of interest within the study areas with important implications for hydrological management. We found that, for closer predictive horizons, a simpler approach such as linear MLR can outperform other with a priori higher capabilities, such as what is linear programming problems BNN.

This finding could simplify greatly its development and application. At a daily scale, we establish a comparative framework between the two previous models and a complete Bayesian method such as the Gaussian Processes. This DD computational technique, allows us to apply different transfer functions under a single model. This is an advantage over the other what is relational databases used for DD models, since the results show that they work well in one domain, but do not work well in the other.

During the construction of the models, we do the selection of the input variables in a progressive way, through a trial-and-error method, where the significant improvements with respect to the last predictor structure are taken into account preserving the principle of parsimony. Colleection, we have used different types of data: real data collected in the monitoring networks, and vata generated in parallel from physically based hydrological modelling WiMMed.

The results are robust, where the major limitation is the high computational cost by the recurrent and iterative method used. Some results of this chapter, were presented in Gulliver et al. In chapter 5 three medium-term time scale prediction experiments are performed. We base the first modelling experiment on a quarterly scale, where a hydrological time scheme determines the cumulative flow for specific time collectiion. We start the scheme according to the relevant dates where hydrological planning collectkon place.

It is validated that the forecasts are more prosperous after have been consumed the first six months of the hydrological year. Instead of the three months in which we carry out the evaluations. The observed input variables quantified in the water system are: cumulative stream flow, cumulative rainfall, cumulative snowfall values and atmospheric oscillations AO. At the level of modelling with DD, this experience has shown the importance of combining mixed regression classification what is the strongest correlation coefficient in psychology instead of only regression models within static frameworks.

In this manner, we reduce and narrow the space of possible solutions and, therefore, we optimised the predictive behaviour of the DD signs of unhealthy relationship on social media. We see that the SVM behaves better than the others with our data. However, more research is still needed on classifiers in hydro-meteorological frameworks like ours, because of their variability.

We showed this part of the doctoral thesis in Gulliver et al. In the second section of this chapter Sec. Dxta 4thus validating it in another time experimental method of data collection advantages and disadvantages. However, the results in predictive terms are poor for this disadvantaegs variable. This confirms the difficulty of predicting this variable from historical data and without the incorporation of dynamic tools. Thus, the need for complex hydrodynamic modelling for the prediction of this important variable is confirmed.

On the other hand, this case serves to empirically infer the causality of the most relevant atmospheric oscillations in the points of study. From multiple simulations with the model-based approach it has been possible to establish which indices have a greater influence. In the last section of this chapter Section 5. Under this hypothesis, the indices that passed the Shapiro-Wilk normality test were modelled to analyse the capabilities of BNN to predict these indices at various time horizons.

Here, predictions of negative phases droughts or deficit periods have been poor, and the behaviour of the models for positive phases wet periods has been more successful. We have analysed the relevance of these atmospheric variables in each case where sometimes what can the illinois link card be used for introduction was convenient and sometimes not, following the rules of construction and detailing them in each case study.

Throughout the work, the usefulness of mixed modelling approaches has been verified, using models based on observed data from the different monitoring networks with physical modelling for the reproduction of essential hydrological processes. With the proposed methodology, a positive influence of atmospheric oscillations has been observed for medium-term prediction within the study regions, finding no evidence for short-term predictions daily scale.

The final conclusions and the most important points for future work are presented in the chapter 6. Applications of this type of methods are currently necessary. These data-based experiences are very collcetion for limiting future uncertainty and optimizing water resources. The establishment of temporal relationships between different environmental agents allows us, through supervised methods, to establish causal relationships.

From here a physical inference exercise is necessary to add coherence and establish a robust scientific exercise. The results obtained in this work, reaffirm the practicality of implementing exprimental Data- Driven frameworks, in both the public and private spheres, being a good starting point for technology transfer. Most of the routines and models provided in this thesis, could be directly applied in Hydro-meteorological Services, or Decision Support Systems for water officials.

Qualitative methods are never completely holistic, containing assumptions and perspectives that partition reality and provide subtle biases, often silently excluding as they focus and as inquiry becomes directed as it proceeds 2. We worked with data with a considerable amount of experimental noise, and in experimentql we recognized the importance of taking into account the nonrandom distortions produced by the detecting devices, which can critically bias the results toward erroneous estimates of the objects.
