Authors: Soetopo Widandi ,   Suhardjono, Andawayanti Ussy , Sayekti Rini Wahyu , Ismoyo Janu 
Published: April 2018

AbstractThree models of release rule for operating a large reservoir for irrigation water supply are discussed in this paper. The models are a 50-grid storage continuous line restricted release rule, a single rule curve release rule, and a multi 4 rule curves release rule. These three models are to be optimized by stochastic simulation using 30 year inflow data with the maximization of the average monetary annual production in the irrigation area as the objective function. The purpose of this study is to look for the proper release rule for operating the Sutami Reservoir. The optimization is done first by the random search stochastic simulation model to generate a number of alternative solutions. Using these solutions as a generation of solutions, the genetic algorithm model is the applied to improve the solution. Afterward the best of solutions are checked by the Add-Ins Solver of MS-Excel 2010 to see if they can still be improved further. The results show that the 4 rule curves model gives the best solution with the average monetary annual production in the irrigation area of USD 72.248 million.

Authors: Wałęga Andrzej , Cebulska Marta , Gądek Wiesław 
Published: April 2018

AbstractThe objective of the research was to look into the role that bioretention systems play in a decentralized management of stormwater runoff from the impervious areas. The study took place at a catchment of a low permeability and equipped with a combined sewer system. Two rainfall options were selected: actual rainfall intensity q = 105.65 dm3∙s−1∙ha−1 and a hypothetic rainfall with a probability of exceedance p = 10% and q = 40.7 dm3∙s−1∙ha−1. All calculations were carried out using the SWMM EPA program (storm water management model; Environmental Protection Agency). They have shown that the bioretention system reduces the cumulative flow rates by over 55% and the flood wave volume by over 54%. Moreover, it was found that, a precipitation pattern significantly influences runoff from the urban catchment.

Published: April 2018

AbstractThis study detected, for the first time, the long term annual and seasonal rainfall trends over Bihar state, India, between 1901 and 2002. The shift change point was identified with the cumulative deviation test (cumulative sum – CUSUM), and linear regression. After the shift change point was detected, the time series was subdivided into two groups: before and after the change point. Arc-Map 10.3 was used to evaluate the spatial distribution of the trends. It was found that annual and monsoon rainfall trends decreased significantly; no significant trends were observed in pre-monsoon, monsoon, post-monsoon and winter rainfall. The average decline in rainfall rate was –2.17 mm·year−1and –2.13 mm·year−1for the annual and monsoon periods. The probable change point was 1956. The number of negative extreme events were higher in the later period (1957–2002) than the earlier period (1901–1956).

Abstract
The aim of the article is to get a closer overview of the non-instructional methods of the teaching-learning process of geography. To achieve this goal, the results of the international project Borderland: Border Landscapes Across Europe (undertaken in 2012 and 2013, within the framework of LLP-Erasmus Programme) was presented. Special attention was paid on the innovative approach to learning methods, namely learning by doing (LBD) that was experienced in a multinational environment during the project’s implementation.
Coastal Dunes of the Baltic Sea Shores: A Review

Abstract
The article summarises results of studies conducted along the Baltic Sea sandy coasts by scientists involved in coastal dune research, and presents an attempt to describe the types and distribution of dune coasts. The Baltic Sea coasts feature lower and higher foredunes. The lowland behind the coastal dune belt is covered by wandering or stabilised inland dunes – transgressive forms, mainly parabolic or barchans. The source of sediment for dune development includes fluvioglacial sands from eroded coasts, river-discharged sand, and older eroded dunes. Due to the ongoing erosion and coastal retreat, many dunes have been eroded, and some are withdrawing onto the adjacent land. There are visible differences between the south-eastern, western, and northern parts of the Baltic Sea coast with respect to dune development. The entire southern and eastern coast abounds in sand, so the coastal dunes are large, formerly or currently wandering formations. The only shifting dunes are found at the Polish and the Russian–Lithuanian coasts on the Łebsko Lake Sandbar as well as on the Vistula and Curonian Spits. The very diverse shoreline of the south-western coast experiences a scarcity of larger sandy formations. Substantial parts of the Baltic Sea sandy coasts have been eroded or transformed by humans. The northern part of the Baltic Sea coast features mainly narrow and low sandy coasts (e.g. in Estonia). Further north, sandy dunes are virtually absent.

Abstract
Demnate commune and High-Tessaout valley are located in the Moroccan central High-Atlas. They have a great and much diversified geological and geomorphological heritage and exceptional landscapes of high mountains. The data obtained from the current work indicate that the studied area present high tourist vocation, in the fact that this territory preserves a large number of geosites linked to many witnesses fossils of extinct animals such dinosaurs footprints, outcropping rock formations of the Precambrian and Mesozoic. Further, it has many remarkable landforms and geosites such as canyons, natural bridge, spectacular waterfalls and scree slopes. The findings support that the area attracts many tourists every year. However, this number remains restricted due to the lack of tools of promotion and mediation of its geoheritage and also due to the low exploitation of the geodiversity. Regarding this situation, geotouristic routes represented on touristic map appear as an essential tool for geotourism promotion and as an efficient means of geosciences popularisation. This paper illustrates three geotouristic routes describing the main geosites in rural areas of Demnate and High-Tessaout valley. These geotourism itineraries can help to explain the high potential interest of the studied areas in geotourism terms.

Authors: Marynowska Weronika Cecylia 
Published: April 2018

Abstract
Lake disappearance as a natural stage of evolution of lakes is an extremely important issue in the landscape and ecosystem research context. Studies of the changes that occur in the lake landscape, characteristic in the northern part of Poland, are aimed at defining the cause and forecasting the results. The possibilities of the Geographic Information Systems (GIS) were used in this paper to analyse and visualise the process of lake disappearance in the Iława Lakeland Landscape Park. GIS technologies which primarily are used for gathering, storing, processing and presenting spatial data have been used to interpret changes in lakes coverage over a period of 100 years. The analysis were based on data bases and cartographic former maps such as hydrographic maps, attribute data and bathymetric plans. The data was gathered by transfer from different geoportals, next vectorised, and then preprocessed. Former maps were rectified. The lake disappearance process was presented in several forms: lake cards, animations and interactive map. Basing on the GIS analysis about lake disappearance in Iława Lakeland Landscape Park it was possible to state that lakes are disappearing in rate of 3.99 ha a−1.

Thermokinetic study of the formation of carbon monoxide in the dimerization of isocyanic acid
Authors: Tho Nguyen Huu , Tri Nguyen Huu 
Published: April 2018

<p>The mechanism of the dimerization of HNCO was investigated using the ab initio method. The barrier heights, reaction energies and geometrical parameters of the reactants, products, intermediates and transition state were studied. It was found that there are possibly three reaction channels. The B3LYP 6-311++G(3df,2p)//CCSD(T) 6-311++G(d,p) calculated barriers show that reaction of formation of four-membered ring O=CNHNHC=O is more favorable than formations of CO<sub>2</sub> or CO. The reaction pathway of the formation of carbon monoxide from the dimerization of isocyanic acid is a new pathway. Its rate constant is very small, k = 2.62´ 10<sup>-19</sup> cm<sup>3</sup>/molecule/s at 2500K, 1atm, which is about 2000 times as small as rate constant of formation CO from a bimolecular mechanism of HNCO with Ar.</p>
