Contiene una descrizione dettagliata del corso di Costruzioni Idrauliche 2017 presso il Dipartimento di Ingegneria Civile, Ambientale e Meccanica dell'Università di Trento.
A variation on the linear reservoir method to design culverts. It use the so called "metodo italiano". It is actually known to have problems. However, for historical reasons, I explain it to students.
This is the lecture with which I usually conclude my class in hydrology. It talks about the impact of climate change on hydrology. Wit some specific on the Alpine areas.

Introduzione all'uso della Console di OMS e di QGIS (per le analisi del corso...Riccardo Rigon
Le slides contengono una descrizione della Console di OMS e di alcuni comandi elementari di QGIS per gestire i dati spaziali che saranno utilizzati nel corso di Idrologia dell'Università di Trento (2017).
1. The document discusses long wave radiation emitted by the Earth's surface and atmosphere. It describes the Earth as a gray body that emits radiation in the infrared band given its average surface temperature of 288K.
2. It explains that the atmosphere absorbs and re-emits long wave radiation from the Earth's surface, and without this greenhouse effect the average surface temperature would be around -17C instead of 15C.
3. It provides equations to calculate long wave radiation from a surface based on the surface temperature and the atmospheric emissivity and temperature, noting that multiple parameterizations exist to estimate the atmospheric emissivity.
1) The atmosphere is not a perfect absorber of radiation like a blackbody, but rather a "gray body" that absorbs some but not all radiation.
2) Radiation passes through the Earth's atmosphere, with 45-50% of incident radiation reaching the ground. Some radiation is reflected and scattered by the atmosphere.
3) Shortwave radiation that enters the atmosphere is transferred to the ground through reflection, absorption, and transmission. The incoming and outgoing radiation must be in balance.
1) Solar radiation intensity governs seasonal climate changes and local climates due to variations in the sun's apparent height.
2) Incoming solar radiation is not evenly distributed across latitudes, creating heating imbalances between the equator and poles.
3) Calculations of solar radiation incident on Earth's curved surface must account for variables including latitude, time of day, day of year, and Earth's tilted orbit which causes seasons.
It contains the description of the Solar radiation relation with the astronomical movements of both Earth and sun. Used in the class of Hydrology at the University of Trento

Metodo dei minimi quadrati
Consiste nel definire lo scarto quadratico tra le misure, di ECDF, e la probabilità

Tale minimizzazione si ottiene derivando l’espressione dello scarto rispetto
agli m parametri
Ottenendo così le m equazioni in m incognite necessarie.

Come risultato abbiamo 3 coppie di parametri, tutti in un certo senso ottimi.
Per distinguere quali tra questi insiemi di parametri è migliore, dobbiamo usare
un criterio di confronto (un test non parametrico). Useremo test di Pearson.
