The main aim of this study is to apply geographic information system (GIS) and data mining techniques to get the attribute data in a spatial and tabular form related to district wise availability of standing water bodies in their area and number of Bihar state. An analysis has been done on available spatial data and maps to get non-spatial/ tabular data, which are in a more easily understandable form. Data extracted district-wise related to area and number of standing water bodies according to their size of Bihar state. Study shows that the number and area of standing water bodies in Madhubani, East Champaran and Patna districts are 2185, 1753, 350 and 2355.42, 6752.36 and 8429.68 ham respectively. In this way, number and area of standing water bodies of other districts of Bihar are also extracted from geodatabases and digitized maps. This type of information is more useful than the spatial data because a common person is able to understand these tabular data and they can use this data for their own purposes. These data can be utilized by scientific personnel as well as farmers and that will be used in agriculture for better utilization of water resources to enhance agricultural productivity and income of farmers of Bihar state.

Small Water Bodies

Developing indicators to monitor environmental change in wetlands with the aid of Earth Observation Systems can help to obtain spatial data that is not feasible with in situ measures (e.g., flooding patterns). In this study, we aim to test Sentinel-2A/B images suitability for detecting small water bodies in wetlands characterized by high diversity of temporal and spatial flooding patterns using previously published indices. For this purpose, we used medium spatial resolution Sentinel-2A/B images of four representative coastal wetlands in the Valencia Region (East Spain, Mediterranean Sea), and on three different dates. To validate the results, 60 points (30 in water areas and 30 in land areas) were distributed randomly within a 20 m buffer around the border of each digitized water polygon for each date and wetland (600 in total). These polygons were mapped using as a base map orthophotos of high spatial resolution. In our study, the best performing index was the NDWI. Overall accuracy and Kappa index results were optimal for −0.30 threshold in all the studied wetlands and dates. The consistency in the results is key to provide a methodology to characterize water bodies in wetlands as generalizable as possible. Most studies developed in wetlands have focused on calculating global gain or loss of wetland area. However, inside of wetlands which hold protection figures, the main threat is not necessarily land use change, but rather water management strategies. Applying Sentinel-2A/B images to calculate the NDWI index and monitor flooded area changes will be key to analyse the consequence of these management actions.

Based on the current state’s emphasis on environmental governance, combined with a series of pollution problems faced by Dianchi Lake, traditional environmental governance methods do not have real-time effective information analysis and processing capabilities. Therefore, the construction of an information visualization system that meets Dianchi wastewater treatment is currently the general trend of environmental construction.In this paper, the (B/S) model system architecture is used to establish a WebGIS-based Dianchi basin wastewater treatment visualization system, which greatly improves the system’s interaction and development costs.The system database adopts the spatial database model of GeoDatabase, which well solves the correlation between spatial data and attribute data, and can display and analyze corresponding data according to the data format and attributes.It provides an accurate and efficient visualization platform system for Dianchi pollution treatment. The commissioning of this system has greatly improved the governance efficiency of the relevant management departments of Dianchi Lake, and provided reliable data support for the dynamic adjustment of the department’s governance strategy.

This article analyzes the applicability of spatial data for evaluating and monitoring changes in land use and their impact on the local landscape. The Coordination of Information on the Environment (CORINE) Land Cover database was used to develop a procedure and an indicator for analyzing changes in land cover, and the continuity of different land use types. Changes in land use types were evaluated based on land cover data. The results were analyzed over time to track changes in the evaluated region. The studied area was the Region of Warmia and Mazury in Poland. The preservation of homogeneous land cover plays a particularly important role in areas characterized by high natural value and an abundance of forests and water bodies. The study revealed considerable changes in land cover and landscape fragmentation in the analyzed region.

Sudden Water Pollution

Sudden water pollution incidents are incidents that the pollutants affected by some unexpected factors following into water bodies, resulting in contamination of water resources within a short period, which will lead to emergencies of adverse impacts on society. According to the ways of pollutants following into water bodies, sudden water pollution incidents could be classified into four categories. Sudden water pollution incidents have potentially risks, and some positive approaches should be adopted to control them. Those have been discussed in the research that three sudden water pollution incidents having taken place in Huanggang River basin and their treatment measures, and the four hidden pollution hazards existing in Huanggang river basin have been analyzed.

Present study deals with the physicochemical assesment of Khelna reservoir water. Life in water depends upon the physicochemical conditions prevailing in that water. A total of 20 parameters were analyzed at seasonal intervals. Results of present study reveals that all selected physicochemical parameters were found in normal range as per the guidelines of WHO. The water is potable and safe for drinking and irrigation purpose. In order to maintain better quality of water, regular monitoring of quality of water and protection and conservation of water bodies is required. A proper awareness among society has to be created about protection and conservation of water resources.

Vegetation in urban areas can be viewed, as compensation for environmental change due to urbanization of plant diversity affecting the diversity of animals in an ecosystem, the loss of plant species will disrupt the food webs in the ecosystem. Research on the diversity of soil insects found in shade trees species is still not widely done. The purpose of this study were to identify the types of soil insects found in shade trees along Dinoyo and Tlogomas roadside in sub-district of Lowokwaru, Malang and to characterize spatial distribution of soil insect species found in shade trees along Dinoyo and Tlogomas roadside in sub-district of Lowokwaru Malang by using GIS application. Sampling was conducted at two different locations (MT Haryono and Tlogomas Road). Soil insect analysis was calculated using Shannon-Wiener (H') index at different sites. Variables measured were Relative Frequency (FR) and Relative Abundance (KR), while mapping Spatial descriptions. Distribution of soil insects was done by stages in spatial data analysis including digitization, attribute data, map overlay, and map output results. The results of this study obtained the number of species of soil insects as many as 14 species with a total of 287 individuals. Soil insects most commonly found were family Formicidae, the species of Momorium destructor with the number of individuals as much as 87 individuals, and Paratrechina longicornis as many as 86 individuals.
