Annual runoff assessment in arid and semiarid Mediterranean watersheds under the Budyko's framework

2017

The solution of many practical water problems is strictly connected to the availability of reliable and widespread information about runoff. The estimation of mean annual runoff and its interannual variability for any basin over a wide region, even if ungauged, would be fundamental for both water resources assessment and planning and for water quality analysis. Starting from these premises, the main aim of this work is to show a new approach, based on the Budyko's framework, for mapping the mean annual surface runoff and deriving the probability distribution of the annual runoff in arid and semiarid watersheds. As a case study, the entire island of Sicily, Italy, is here proposed. First, ti…

Late Pleistocene Detrital Sediment Yield of the Jura Glacier, France

2001

AbstractMeasures of present-day glacial erosion vary widely with the technique employed. This paper quantifies the glacial material trapped in a proglacial lake during the Würm glacial period. The Combe d'Ain site was occupied by a meltwater lake where all the detrital material entering it from the Jura glacier accumulated. Sediment yield is computed from three factors: (1) the size of the sediment source area, (2) the length of time the system operated, and (3) the volume of sediment trapped. The sediment budget of the lake system suggests a detrital sediment yield of 4400±1700 metric tons per square kilometer and per calendar year. This represents a denudation rate of 1.6±0.6 mm per year,…

ON THE USE OF SATELLITE THERMAL DATA FOR DETERMINING EVAPOTRANSPIRATION IN PARTIALLY VEGETATED AREAS

1992

Abstract The use of satellite data for determining daily evapotranspiration over completely vegetated areas has been analysed by different authors. However, if the soil surface is partially covered by vegetation the problem becomes more complicated, because in this case the value of the temperature measured by the satellite varies with the viewing geometry. In this work we have studied the influence of the satellite observation angle for crops with different cover degree, field geometry and ground emissivity. For this purpose we have used the simplified relation proposed by Jackson et al.LET d=Rnd−B(T3−T a)iwhere ET 4 and R nd are the daily values of evapotranspiration and net radiation res…

Erosion rates and sediment budgets in vineyards at 1-m resolution based on stock unearthing (Burgundy, France).

2008

Abstract A new and simple method is developed to efficiently quantify erosion and deposition rates based on stock unearthing measurements. This is applicable to spatial scales ranging from plot to hillslopes, and to time scales ranging from single hydrologic events to centennial scales. The method is applied to a plot area on vineyard hillslopes in Burgundy (Monthelie, France), with measurement of 4328 vine plants. A sediment budget established at the plot scale shows a mean soil lowering of 3.44 ± 1 cm over 20 years, involving a minimal erosion rate of 1.7 ± 0.5 mm yr − 1 . Locally, erosion rates can reach up to 8.2 ± 0.5 mm yr − 1 . This approach allows the sediment redistribution to be m…

Proglacial sediment dynamics from daily to seasonal scales in a glaciated Alpine catchment (Bossons glacier, Mont Blanc massif, France)

2018

The sediment yields of Alpine catchments are commonly determined from streamload measurements made some distance downstream from glaciers. However, this approach indiscriminately integrates erosion processes occurring in both the glacial and proglacial areas. A specific method is required to ascertain the respective inputs from (i) subglacial and supraglacial sediments, (ii) proglacial hillslopes and (iii) proglacial alluvial areas or sandurs. This issue is addressed here by combining high‐resolution monitoring (2 min) of suspended sediment concentrations at different locations within a catchment with discharge gauging and precipitation data. This methodological framework is applied to two …

Iedzīvotāju ienākuma nodokļu un valsts sociālā apdrošināšanas obligāto iemaksu piemērošana Latvijā

2018

Šī maģistra darba mērķis ir analizēt iedzīvotāju ienākuma nodokļu un valsts sociālā apdrošināšanas obligāto iemaksu piemērošanu Latvijā un to ietekmi uz valsts budžetu, kā arī sniegt priekšlikumus Latvijas nodokļu sistēmas uzlabošanai. Darba autore izvēlējas šo tēmu, jo uzskata, ka nodokļu politika ir ļoti aktuāls jautājums mūsdienās, kā arī tas ir būtisks instruments, lai palīdzētu valstij attīstīties. Darbā tiek analizēti darbaspēka nodokļi: IIN un VSAOI, kā arī, balstoties uz esošā gada izmaiņām, tiek aprēķināta darba samaksa pirms un pēc nodokļu reformas 2018. Darbā tiek apskatīti dažādi jautājumi saistībā ar šiem nodokļiem: gan nodokļu reforma, gan darbasspēka nodokļu ietekme uz valsts…

Darbaspēka nodokļu izpēte

2016

Darba mērķis ir balstoties uz nodokļu politikas teorētiskajām atziņām un darbaspēka nodokļu jaunāko aktualitāšu un prakses izpēti novērtēt to lomu budžeta ieņēmumu veidošanā, kā arī izstrādāt priekšlikumus sabalansētas darbaspēka nodokļu politikas izveidei. Darbaspēka nodokļi ļoti bieži ir diskusiju objekts, kuru pamatā galvenokārt ir neapmierinātība ar augsto nodokļu slogu. Vienlaikus tiem ir īpaša loma budžeta ieņēmumu veidošanā. Lai sasniegtu mērķi, autore izpēta teorētiskās atziņas par nodokļu nepieciešamību, sadalījumu un to ietekmi uz budžetu. Tiek aplūkotas aktualitātes Latvijas nodokļos un darbaspēka nodokļu izmaiņas Baltijas valstīs. Tiek aplūkoti Gulbenes novada pašvaldības nodokļ…

Iedzīvotāju ienākuma nodokļa piemērošana BALTIJAS VALSTĪS

2022

Maģistra darba mērķis ir izanalizēt iedzīvotāju ienākuma nodokļa piemērošanu Baltijas valstīs un to ietekmi uz iedzīvotāju ienākumiem, kā arī, sniegt priekšlikumus IIN pilnveidošanai Latvijā. Darba autors izvēlējas augstākminēto maģistra darba tēmu, jo uzskata, ka IIN piemērošana ir īpaši aktuāls jautājums mūsdienās, kā arī ir būtisks instruments ar kuru palīdzību valsts var attīstīties un mazināt nevienlīdzību starp nodokļu maksātājiem ar dažādiem ienākuma līmeņiem. Maģistra darbā tiek pētīta IIN piemērošanas kārtība, tiek analizēta IIN ietekme uz valsts budžetu, kā arī tiek veikta darba tirgus analīze kopā ar citiem aktuālajiem jautājumiem. Darbs sastāv no trim nodaļām. Pirmajā nodaļā tik…
