Inundation Height

Cerme District is located in South Gresik area which has an area of 71.73 km2. This area is located above the height of ± 4m sea level. While the slopes of the Cerme District are in the range 0-2% with a slope to the north. The land-use plan map of Cerme sub-district should be designated as an industrial area and residential area which is still inundated at several points. One of these puddles is in the left-hand cerme drainage system, especially in the secondary sub-catchment cerme kidul. The inundation height is between 20-30cm with inundation ± 2-4 hours. This final project can find out the results of the planned debit calculation using existing land use and land use plans, the difference in the calculation of the debit reaches 60%. While the calculation of canal capacity using planned land use can be known that 2 "safe" and 8 channel segments "need normalization".

This chapter tells the story of how the early Adirondack Park Agency (APA) struggled to meet the state's assignments. It details what the state legislature gave to the early APA: an extremely ambitious to-do list and a ridiculously small budget. Much of the work depended on the men who had also worked for the Temporary Study Commission (TSC). The chapter analyses the story of George Davis who turned the idea for his dissertation into a big map that transformed life in the North Country. Davis's passion was protecting land that he thought should remain free of human impact. His thesis would compile data to show which Adirondack lands were suitable for development and which should remain undisturbed. The chapter then shifts with the APA chairman, Richard Lawrence who overcame opposition on several fronts as he struggled to maintain a working majority of board members, and the tireless work of Peter Paine, a well-connected lawyer, who argued stridently for the two plans. Ultimately, the chapter explains the significance of the APA map project. It argues that map making was important because the legal requirements for the land use plan were unusual, as most land use laws use text to describe the boundary lines of the area being regulated.

SUMMARYIn many developing countries, high rates of deforestation and biodiversity loss make conservation efforts urgent. Improving existing land-use plans can be an option for enhancing biodiversity conservation. We showcase an approach to enhancing an existing forest land-use plan using widely available data and spatial tools, focusing on Argentina's Southern Yungas ecoregion. We mapped the distribution of wilderness areas and species and habitats of conservation concern, assessed their representation in the land-use plan and quantified potential changes in habitat availability and forest connectivity. Wilderness comprised 48% of the study area, and the highest concentrations of elements of conservation concern were in the north. In the current land-use plan, wilderness areas often occur in regions where logging and grazing are allowed, and a large proportion of the forest with the highest conservation value (43%) is under some level of human influence. Furthermore, we found that deforestation being legally allowed in the land-use plan could reduce forest connectivity and habitat availability substantially. We recommend updating the current land-use plan by considering human influence and elements of conservation concern. More broadly, we demonstrate that widely available spatial datasets and straightforward approaches can improve the usefulness of existing land-use plans so that they more fully incorporate conservation goals.

The changes in both climate and land cover have some impact on water resources. Dengkeng watershed, mostly located in Klaten district of Central Java Province. Dengkeng River as one of the raw water source of agriculture and drinking water of society, besides as main water body in the drainage system. Climate change and land use directly affect land use patterns, water availability, flood control performance, local social and economic development, and so on. Therefore, studying the impacts of climate change and land use becomes very important. The HEC-HMS model is used in this study. The observed discharge data used AWLR data of Paseban with period 2005-2017, climate data used nearest post data with observation period 1979-2014. While changes in land use were used data in 1990, 2000 and 2011. The results of the analysis on climate change showed an increase in rainfall both monthly rainfall and maximum daily rainfall. While land use changes can be reviewed on the watershed hydrological parameters, one of which is the change of Curve Number (CN). An increase in CN value has an impact on increasing runoff. However, if viewed against the availability of water, then there is a trend of decline.

The City

For quite some time, professional planning is being practiced in our cities. Unfortunately, drainage planning is the most neglected component of our city planning and management activities. Drainage engineering is done mostly on an ad hoc basis, often overtaking drainage planning. To understand the drainage problem of our cities, Chittagong in particular, Chaktai Commercial Area was identified as the case study area for further exploration and analysis. This case study examines the existing situation, assessing causes behind the problems, inquiring about the likings and disliking of the stakeholders, and identifying possible solutions as an essential input towards arriving at appropriate planning decisions. It identifies the guiding principles relating to the effective integration of a drainage network in the land use plan for the city. Considering physical characteristics, topography, catchment area and the routes of existing drainage channels, the urban area has been divided into 10 drainage areas. The Master plan sets out a staged development program of storm water, drainage and flood control works of the above drainage area up to the year 2015 to meet the Storm Water Drainage and Flood Control problems. Chaktai is the major seat of trade and commerce in Chittagong. It is observed that though Chaktai has lost its past glory as a national business centre controlling food business in the whole country, still it has retained its importance as a regional business hub and is continuing to contribute significantly to the national economy. The study thus helps us understand the nature, type and magnitude of the drainage and water logging problems faced by the city dwellers. The policy proposals and recommendations that are provided in the paper could be considered while preparing a land use plan for a city.DOI: http://dx.doi.org/10.3329/jbip.v2i0.9556  Journal of Bangladesh Institute of Planners Vol. 2, December 2009, pp. 49-60

The 19Th Century

Thousands of sub-circular closed depressions or “mardelles” are observed on Keuper marls of the North-eastern Paris Basin. Their anthropogenic or geological origin is highly debated by archaeologists and naturalists since the first half of the 19th century. During rescue archaeological excavations along the high speed train line ‘LGV-Est Européenne’ seven closed sub-circular depressions were investigated to resolve the question of their origin, their formation processes and their evolution of their sedimentary filling. To that goal, a new field methodological approach combining geoarchaeology, archaeobotany and archaeology was carried out by the optimization of mechanical excavator. The realisation of long and deep trenches allowed direct observations of both substratum and sedimentary filling. This study evidences the natural origin of closed depressions by the play of the following processes: (1) Initiation of closed depressions is realised by ancient fractures affecting the Triassic marls; (2) Deepening of closed depressions is realised by alteration of superficial marls and residual clays passage down several wells formed through existing faults; (3) When the closed depression exists, the modifications of the shape of the closed depression's edges, is due to degradation of marl blocks; (4) The following sedimentary filling traduces environmental conditions influenced by forest evolution and land use changes since Antiquity. Direct observations at the scale of closed depression complete spatial information from a Lidar survey along the LGV-Est line. The analysis of this survey shows alignments of closed depressions with orientations similar to those of the drainage system, the origin of which is probably linked to the fracturing of the Keuper marls. Finally, even if a process of natural formation is envisaged, a role of human activity in the initiation of the process could be envisaged in particular by the action on the evolution of the land use (plant cover) and thus in the marls karstogenesis.

The paper reviews various methods of flood control in the lower Yare Basin which has been subject to serious flooding caused by storm surges in the North Sea and by fluvial floods. This area is known as the Broads and is an area of scenic beauty, includes many sites of scientific interest and is a popular tourist area. The effects of the different flood control options on the environment are discussed. The primary economic justification for flood prevention was found to arise from the conversion of poor quality marsh grazing land to arable or improved pasture once the risk of saline flooding was removed. The consequences of this change in land use on the flora and fauna have aroused much concern among environmentalists.

Abstract Recently urban waterlogging problems have become more and more serious, and the construction of an airport runway makes the impervious area of the airport high, which leads to the deterioration of the water environment and frequent waterlogging disasters. It is of great significance to design and construct the sponge airport with low impact development (LID) facilities. In this paper, we take catchment N1 of Beijing Daxing International Airport as a case study. The LID facilities are designed and the runoff process of a heavy rainfall in catchment N1 is simulated before and after the implementation of LID facilities. The results show that the total amount of surface runoff, the number of overflow junctions and full-flow conduits of the rainwater drainage system in catchment N1 of Beijing Daxing International Airport are significantly reduced after the implementation of the LID facilities. Therefore, the application of LID facilities has greatly improved the ability of the airport to remove rainwater and effectively alleviated the risk of waterlogging in the airport flight area. This study provides theoretical support for airport designers and managers to solve flood control and rainwater drainage problems and has vital practical significance.

Snow Gliding

Abstract. Snow processes might be one important driver of soil erosion in Alpine grasslands and thus the unknown variable when erosion modelling is attempted. The aim of this study is to assess the importance of snow gliding as a soil erosion agent for four different land use/land cover types in a subalpine area in Switzerland. We used three different approaches to estimate soil erosion rates: sediment yield measurements in snow glide depositions, the fallout radionuclide 137Cs and modelling with the Revised Universal Soil Loss Equation (RUSLE). RUSLE permits the evaluation of soil loss by water erosion, the 137Cs method integrates soil loss due to all erosion agents involved, and the measurement of snow glide deposition sediment yield can be directly related to snow-glide-induced erosion. Further, cumulative snow glide distance was measured for the sites in the winter of 2009/2010 and modelled for the surrounding area and long-term average winter precipitation (1959–2010) with the spatial snow glide model (SSGM). Measured snow glide distance confirmed the presence of snow gliding and ranged from 2 to 189 cm, with lower values on the north-facing slopes. We observed a reduction of snow glide distance with increasing surface roughness of the vegetation, which is an important information with respect to conservation planning and expected and ongoing land use changes in the Alps. Snow glide erosion estimated from the snow glide depositions was highly variable with values ranging from 0.03 to 22.9 t ha−1 yr−1 in the winter of 2012/2013. For sites affected by snow glide deposition, a mean erosion rate of 8.4 t ha−1 yr−1 was found. The difference in long-term erosion rates determined with RUSLE and 137Cs confirms the constant influence of snow-glide-induced erosion, since a large difference (lower proportion of water erosion compared to total net erosion) was observed for sites with high snow glide rates and vice versa. Moreover, the difference between RUSLE and 137Cs erosion rates was related to the measured snow glide distance (R2 = 0.64; p < 0.005) and to the snow deposition sediment yields (R2 = 0.39; p = 0.13). The SSGM reproduced the relative difference of the measured snow glide values under different land uses and land cover types. The resulting map highlighted the relevance of snow gliding for large parts of the investigated area. Based on these results, we conclude that snow gliding appears to be a crucial and non-negligible process impacting soil erosion patterns and magnitude in subalpine areas with similar topographic and climatic conditions.

AbstractDespite harsh climate, agriculture on the northern margins of Russia still remains the backbone of food security. Historically, in both regions studied in this article – the Republic of Karelia and the Republic of Sakha (Yakutia) – agricultural activities as dairy farming and even cropping were well adapted to local conditions including traditional activities such as horse breeding typical for Yakutia. Using three different sources of information – official statistics, expert interviews, and field observations – allowed us to draw a conclusion that there are both similarities and differences in agricultural development and land use of these two studied regions. The differences arise from agro-climate conditions, settlement history, specialization, and spatial pattern of economy. In both regions, farming is concentrated within the areas with most suitable natural conditions. Yet, even there, agricultural land use is shrinking, especially in Karelia. Both regions are prone to being affected by seasonality, but vary in the degree of its influence. Geographical location plays special role, and weaknesses caused by remoteness to some extent become advantage as in Yakutia. Proximity effect is controversial. In Karelia, impact of neighboring Finland is insignificant compared with the nearby second Russian city – Saint Petersburg.
